Jen-Ken Kilns and Orton have produced the most user friendly and powerful, kiln controller for artists. If the Jen-Ken Kiln can perform all the above tasks, then all of the above settings will been turned on. The Chilipepper is a low firing annealing kiln and will only have the ­BEAD- setting turned on. The AF4X Bead Annealer with flip door will have all of the above turned on except the Cone feature because the
kiln cannot fire that hot. If the kiln is a glass kiln then the CONE feature will be turned off as well.
PLEASE DO NOT PROOGRAM A JEN-KEN KILN FOR GLASS OVER 1700°F AS YOU WILL

This manual contains instructions on the operation of our JenKen Kilns with the AF4X Pre-programmed 3-Key Controller,
that was made for us by Orton, as well as a discussion of general fusing procedures. It is not intended to replace a fusing
class or comprehensive fusing instructional media. The products you put in the kiln to fire will come with or have
available firing schedules for these products. Jen-Ken Kilns wants you to have this manual to get you firing sooner and to see sample programs that you can use or modify the programs to match the one’s for the items you are firing.

SAFETY FIRST

Read and understand all operating instructions before operating your kiln.
SAFETY PRECAUTIONS: Kilns are as safe as any other electrical appliance when used under normal and proper operating conditions. All safety precautions throughout this manual should be observed.
1. Do Not install kiln closer than 12 inches from any surface. (Also, read first paragraph of page 2 “Choosing a Location”).
2. Do Not place the kiln on any flammable surface (i.e. Carpet, Wood, Linoleum, etc.) 3. Make sure all electrical specifications are followed. Use correct voltage, wire size and breaker. Make
sure all connections are tight. Avoid using aluminum wire. 4. Always use the proper receptacle. 5. Install in covered, well-ventilated area. Fumes from the ware have to be vented to the outside. Never
use your kiln outside! Avoid moisture. 6. Always keep children and unsupervised personnel away. Surface will get hot and a burn could result.
Be extremely careful when working near a kiln! 7. Do not operate kiln over maximum temperature rating. (Ceramic to 2300°F, Glass to 1700°F) 8. Fire clay, glaze, overglaze and glass only to the manufacturer’s recommended firing temperature.
Improper fire temperatures could result in damage to your kiln. 9. Replace any worn or defective parts with ONLY genuine JEN-KEN Kiln replacement parts. 10. Never place anything above or under the kiln for storage, nor should anything be propped up against
the kiln. 11. Do not store or use flammable products near your kiln such as gasoline, paint, aerosol cans, paper,
curtains, plastic, etc. 12. A qualified electrician or service person should be used for all electrical service or repairs. 13. If the kiln power cord becomes damaged or corroded, replace the cord immediately. 14. Unplug the kiln before servicing or vacuuming. 15. Always unplug the kiln when not in use or during a storm. 16. Do not touch or attempt to replace the elements while the kiln is plugged in. 17. Kiln must be properly grounded. 18. Never allow the power cord to touch the kiln. Never use an extension cord. 19. Do not drop or slam the lid shut. 20. Let the kiln cool to room temperature before opening the lid. 21. Make sure all switches are turned to “OFF” before opening the lid. 22. NEVER LEAVE THE KILN FIRING UNATTENDED. 23. Use common sense while installing and using.
NOTE: If you are in doubt about anything turn the kiln off, call your dealer or the factory at 863-648-0585 M-F 8-4 Eastern Time
NEVER LEAVE A FIRING KILN UNATTEND. THIS MEANS TO NEVER RUN A KILN AND GO TO BED or LEAVE THE PREMESIS. RUN THE KILN WHEN YOU ARE ABLE TO CHECK ON THE KILN DURING THE FIRING AND AT COMPLETION OF THE FIRNG CYCLE. THEN TURN THE KILN OFF AND ALLOW TO COOL, VERIFY THAT IT IS COOLING AND NO LIGHTS ARE ON THE PANEL. UNPLUG IF NEEDED
SAFETY IS JOB ONE.

ABOUT YOUR KILN
CHOOSING A LOCATION:
The proper location is as important as choosing the right kiln. Below are some safety guidelines: · The best and safest place for your kiln is on a cement floor. (If not, some type of adequate fireproof
material should be used beneath the kiln to prevent a possible fire hazard or prevent discoloration of the floor. i.e. stone tile or drywall) · There must be an air space under all kilns. Concrete blocks may be used to raise the kiln or a metal stand that is available from JEN-KEN Kilns. · Proper electrical service must be available. Refer to the section on Electrical Specifications. · Area should be free from flammable or combustible materials such as gasoline, paper, paints, plastics, etc. · Area should be covered, dry and with good ventilation to the outside. Kilns do not produce foul odors and fumes, however some products (like glazes, china paints, glue, decals and glass) go through a chemical change in the kiln. They could release fumes in the air, that with ample cross-ventilation to the outside, can be kept to a minimum. If ventilation is a problem, then call to see if an Orton Vent System is applicable. · A minimum of 12 inches should be allowed between the kiln sides and the nearest non-combustible wall or object. If the kiln is for pottery or ceramics and the kiln is a 22″ more in height the kiln will need 18″ or more in wall distance for the additional heated area of the kiln. If the wall behind the kiln gets hot then the kiln is too close and should be moved. · Never place the kiln in a small enclosed area (such as a closet, cabinet or very small room). The room a kiln is in should have an open front to dissipate the heat. The room temperature will increase past a reasonable level quickly. Air circulation and ventilation are needed to remove heat and vapors that may be released in the firing. In a larger room, the exterior of the kiln will stay cooler than in a very small room. · Since the exterior of the kiln gets very hot, place the kiln out of the way of children, traffic and work areas. · Never install a kiln outside and avoid undue moisture. · Never let the power cord come in contact with the kiln. The kiln may need to be rotated a little for the cord not to touch the kiln. If the cord makes a right-angle cord to the plug, have the receptacle installed so that the cord goes down and not up. The cord should not make a loop in the air. · Level the kiln using a level across the top of the open kiln.

A Minimum of 12″ Away From a Block Wall
A Minimum of 18″ for All Other Materials.

Kilns must also have an Air Space Under the Kiln. Kilns cannot sit directly on a floor or any surface. Use a kiln stand or concrete blocks with the holes up and down at a minimum. Small Table Top Kilns can be used with a kiln stand or the kiln bricks supplied, as long at the material under the kiln is not combustible. For kilns with base brick put a large smooth stepping stone on the table first, then the base
bricks under the kiln to the outside, then the kiln on top of the base brick.

This Location has the kilns out of the way with a vent hood to remove fumes and heat from the room. Around the alcove cement board has been placed with an air space in between to reduce heat from the
higher temperatures the ceramic kilns produce.

ELECTRICAL SPECIFICATIONS:
To operate the kiln safely and efficiently, your kiln needs the proper electrical outlet with the correct electrical capacity and voltage. The kiln should be on its own breaker/outlet with nothing else running on it when in operation! The chart below will assist you with the selection of the proper wire and breaker size for your JEN-KEN Kiln. A licensed electrician or the local power company should determine if you have the proper voltage. A kiln that is manufactured for 240 volts of service will not run properly on 208 volts. This difference of 32 volts is about a 25% reduction in power, which hinders a kiln from reaching high temperatures. Likewise, if you have 240 volts and you install a kiln manufactured for 208 volts, it will heat so rapidly it will hurt the ware in the kiln. Improper elements can be dangerous. Be sure to have the proper elements in your kiln to match the electrical service.
If you have 208 volts of service, you NEED 208 volt coils. If you have 240 volts of service, you NEED 240 volt coils.
Any changes to your kiln or improper electrical installation will void the warranty.
ELEMENTS: Elements are the coils of wire that produce heat inside the kiln. They are made from a high quality, high-temperature wire. During the firing, they become very soft and when cool become brittle. Life expectancy of the elements will depend on the number of firings, the firing temperatures, and the products being fired. At lower temperatures, the elements will last longer than firing at higher temperatures. Long high firings such as pot melts and glass casting can shorten the element life and are best perform in a side firing style kiln. Care should be taken to make sure that no foreign matter (such as glass, glazes, clay or kiln wash) come in contact with the elements. This will greatly reduce their life expectancy. Regular vacuuming of the kiln lid, bottom and the element grooves is recommended.
In a digital kiln, the coils as a group turn on and off during firing. You will hear the clicking of the relays. It will click more if a slow rate of rise in temperature is used and less if the kiln is told to fire quickly. Your Jen-Ken Kiln has one relay in the single coil kilns and separate relays for the top and side elements models to increase the life of the relays.
Glass kilns that are small have one side coil that will fire the piece well because small pieces of glass do not care where the heat comes from. Larger glass kilns have coils in the lid and side walls. The lid coils do most of the work in the kiln and get the hottest to put an even blast of heat evenly across the shelf. Without the lid coil the piece would have to absorb the heat from the outside and pass it to the center that could cause it to thermal shock. Side coils are supplemental heat and help bring the kiln to temperature. It takes the side and the lid coils to bring the kiln to fusing temperatures.

• The 2829, Oval, JK Squared Series can be ordered as a 45-amp kiln or a high-fire 55-amp kiln, requiring

direct wire installation. The higher amperage means the kiln con fire to higher cone numbers more times

with the added power.

For kilns ordered with the 208-volt elements, the same amperages, wire size, breaker and receptacle should be followed as the 240 chart above.

THE FARTHER THE ELECTRICAL RUN THE HEAVIER THE WIRE HAS TO BE!!!!

If your kiln in not listed call the factory and we will be glad to help you. 863-648-0585
Some kilns are special orders, some are over 30 to 60 years old or limited runs of a unique type of kiln.
So, if in doubt about anything, please call.

KILN BRICK:

All JEN-KEN KILNS are made of hand selected 2300°F refractory brick. This brick is an insulating fire brick that has holes inside and throughout the brick to give it an insulating value. If it was solid brick it would not hold the heat inside the kiln but transfer the heat through the solid material to the outside. The brick is strong as a whole as has a very long life. The brick can chip easily, and care should be taken to avoid bumps while loading and unloading shelves. Frequently vacuum the brick lid, the grooves that the elements are in and the bottom of the kiln. This will remove the dust, sand and loose kiln wash from the kiln.
KILN JACKET:

Your JEN-KEN KILN is encased in a stainless-steel jacket and is also equipped with handles for easy moving. Due to the high temperatures, discoloration may appear on the stainless. A good metal polish can remove this discoloration, but most do not worry about the looks of the kiln after years of use.

ACCESSORIES:

SHELVES: Shelves help you make the most of the inside of your kiln. Shelves are sized a few inches smaller than the inside diameter of the kiln so that they can be placed in and out of the kiln easier. They are made of refractory material so that they should be handled carefully. Shelves come in full and half sizes. Half shelves enable you to fire tall pieces on one side of the kiln and smaller ones on the other side. Should a crack appear in a shelf, break the shelf along the crack and use it as two separate pieces. A good coat of kiln wash should ALWAYS be maintained on top of the shelves. Ceramics use ceramic kiln wash with silica in it and glass requires glass kiln wash with no silica in it to stick to your glass. Store shelves upright on edge leaning on a sturdy structure. Shelves stacked flat can put too much pressure on the bottom shelf and cause it to stress and crack. It usually breaks in the kiln during the next heating.

9

AF4X Kiln Controller
POSTS: Posts are also made from refractory material and should be handled carefully. Post sizes range in heights from ½” to 14″. They are used to support the shelves in your kiln at different levels depending upon the height of the ware you are firing. Usually, three posts will allow you to level the shelf easier (though some prefer four). Glass kilns with lid elements usually only use one shelf at a time. The lid element does most of the work heating the one shelf and would not provide the direct radiant heat to a lower shelf. The top shelf would fire fine with the bottom shelf lagging behind by a large temperature differentiation. Posts do not need to be to the outer edge of the shelf. Move the posts in several inches so that the posts help support more of the middle of the shelf. This will help keep the middle of the shelf supported from underneath without a post there. For large shelves this is required so that the shelf is not supported at the edges, but more towards the center.
RECOMMENED ACCESSORIES:
CERAMIC KILN WASH: Ceramic kiln wash is a protective coating used to keep glazes and porcelain from sticking to the kiln shelf and the kiln floor. Mix the desired amount of dry, high fire kiln wash with water to the consistency of a thick cream and stir thoroughly. Apply several thin coats of kiln wash with a haike brush to the kiln floor and the tops of the shelves, alternating directions. Let dry. When areas wear thin they may be re-coated. If glazes have dripped onto the shelves or the kiln floor, chip the glazes off, sand and smooth the area then reapply the kiln wash. To test kiln wash, slide your hand over the surface of the kiln washed shelf. If you hand is white and powdery, the kiln wash is satisfactory. Perform this test periodically. When the palm of your hand is clean, then re-apply kiln wash to the shelf to prevent the ware from sticking.
Apply a thin coat of kiln wash to the cone supports on the kiln sitter and to the bottom of the sensing rod (where they come in contact with the cone). However, do NOT apply kiln wash to the cone or to the side of the porcelain tube.
GLASS KILN WASH: Glass kiln wash is a coat that keeps glass from adhering to the kiln shelf and the kiln floor in the event of a glass run. It is best to wear a dust mask while cleaning and working with the kiln wash.
First stir the dry kiln wash powder with a spoon to mix the clays. The add the kiln wash to water in a separate sealable container. The most common mixture is 4-5 cups of water to 1 cup of kiln wash powder. Stir well to get all the lumps out. Apply kiln wash using a soft bristled brush to the kiln shelf. Flow the first coat on in one long brush stroke. Repeat this with parallel brush strokes. Allow the shelf to absorb most of the moisture then apply another coat in a cross direction to the first. Between coats be sure to stir the kiln wash in a mixing container with the brush as this will keep the clays from settling. Repeat this for 8-10 THIN coats. If the kiln wash layers are too thick, it will crack when fired and will then need to be removed and reapplied.
Let the shelf stand for several days to dry or place it in the kiln and heat it up to 500°F with the lid propped open a few inches. If the shelf surface is not smooth when dried, use the palm of your hand and rub the kiln washed shelf gently in a circular motion till smooth. Also apply a protective coating of kiln wash to the floor of the kiln, as hot glass can create holes in the fire brick of the kiln. Store the unused kiln wash (liquid or powder) in a sealed container.
Over time the wash may begin to chip or crack, or if applied too thick then then you need to scrape the old kiln wash off with a putty knife and reapply another 8-10 layers.

Always wear Safety Glasses whenever you look into a hot kiln to protect your eyes from infrared and ultraviolet light. Hot gloves made of Kevlar and a Lid Lifter: An operating kiln is very hot. These items can help preclude burns. Caution: A hot handle looks like a cold handle and if the kiln is hot inside the handle is hot also.

SETTING UP YOUR KILN

o Assemble the kiln stand and place it on the floor

in your work space. The round top carriage bolts are on top and the

8 hex head bolts are used on the side of the stand. Tighten all bolts

and make sure the stand is sturdy before putting the kiln on top of the

stand.

o Remove all packaging from the kiln and place it on the stand. Do

not plug it in yet.

o Make sure that your kiln sits completely level. It may be necessary

to use a level to determine

o Open the lid of the kiln and inspect the interior looking for anything Make sure your kiln sits level.

unusual like broken brick.

o Carefully inspect both the side and top heating element coils to make

sure that they are seated back in the grooves. Try to avoid touching

the coils with your fingers, as oil from your skin may cause

premature element failure.

o Vacuum out the interior of your kiln and along the

grooves in the lid to remove any debris that may

come loose when you close the lid or during firing. o Carefully brush kiln wash on the floor of your kiln. This is

Do not brush kiln wash on either the sides or lid of the kiln. Do not

get kiln wash on any heating elements.

o Position the ½” kiln posts on the bottom of the kiln

spaced out evenly to support the kiln shelf.

o Your kiln has been pre-fired at the Jen-Ken factory and should not

NEVER FIRE A KILN UNATTENDED NO MATTER WHAT BRAND KILN, MAKE, OR
MODEL
LET THE KILN FIRE AND SHUT-OFF. IF THE KILN CANNOT BE MONITORED WHILE ON, THEN IT IS FAR BETTER TO TURN THE KILN OFF AND REFIRE AT A LATER TIME. THE ONCE THE KILN
HAS SHUT DOWN AND IS COOLING AND POWER HAS BEEN SWITCHED OFF, THEN AND ONLY THEN, CAN THE KILN BE
CONSIDERED READY TO BE UNMONITORED. DO NOT LET ANYONE NEAR A HOT OR COOLING KILN.

Use the increase and decrease keys to change the display prompt, when you see what you want on the display, press the Program key. Display Lights The controller uses (4) numerical displays and 3 indicator lights. The bottom light tells when the controller is turning on the relays to power the heating elements. The top is lit when the controller is in programming mode, the middle light is lit when the controller is in Program review mode.
Two of the four decimal points on the display are also used as indicators. The decimal point on the far right is used to indicate if the controller is displaying temperature in degrees Fahrenheit (F) or Centigrade (C). If this decimal point is lit, the controller is set to display temperatures in C.

The center decimal point (between the second and third digit) lights whenever the display is showing a time value. The decimal point separates Hours (on the left) from Minutes (on the right).
When the Controller is first turned on
The controller runs a brief self-diagnostic test. The display will light up and the audible alarm should beep. After a few seconds, the display will alternate between the kiln temperature and IDLE. IDLE is the mode where the controller is not actively firing the kiln or being programmed for a firing. Starting a Firing
The display shows -ON- for 5 seconds when the firing begins. The display will show kiln temperature throughout the firing. The temperature display will alternate with alarm messages if any alarms occur. If the controller is programmed to hold at a specific temperature, the remaining Hold Time will alternate with the temperature during the active hold period.
Stopping a Firing
When the controller completes the firing, the display alternates 4 messages: CPLT (Firing Complete); Firing Time (hrs.mins); Final Firing Temperature and Current Kiln Temperature. Press any key to return to IDLE. If you stop the firing before completion with the Stop key, the display will indicate ABRT (abort) in place of CPLT. Press Stop again to return to IDLE
Programming values
Whenever a change is made from the keys, you must press the Program/Start key to load the changes. If the key is not pressed, the controller will simply wait for your next selection. Pressing the Program/Start key will advance you to the next option if you are setting up a program or changing settings.
Note: If you are programming the controller options and no keys are pressed for 90 seconds, the controller will exit the options menu automatically.
Program Review
To review the current program in the controller memory before or during a firing, press the Decrease/Review key. The entire program will automatically scroll through the display and then return to normal operation. Delay time is included in the review.
Repeating a firing
If power is not cycled off to the controller, you can repeat a firing without viewing the entire program, simply press the Decrease/review key when the controller display is showing the desired program group. The controller will scroll through the program review and advance directly to the Start prompt. Press the Program/Start key to set a delay time and again to begin the firing.
Program Sets
The AF4X controller allows the operator to select 1 of 6 program modes for different glass art or craft applications.
The program mode is prompted on the controller display when the controller is turned on. The 6 available modes are:
-LP- For larger glass projects for the kiln (full shelf size and/or 3 or more layers) -SP- For smaller glass projects (small pieces on the same shelf and/or 2 layers) bEAd For bead annealing projects
15

AF4X Kiln Controller
CONE For Cone Firing of Ceramics (Only if kiln is rated for over 1800ºF and is not top firing)
CLA For Metal Clay projects USr For custom firings
-LP- Large Piece Program Mode For pieces that are large in size for the shelf of the kiln (over
2/3 the shelf area and/or 3 or more layers thick). This is a good place to start for that large project knowing that you can speed up the rates (Ra) later if the piece turns out well.

FUSED GLASS PROJECTS
Working with Tested Compatible Glasses
To ensure success when fusing glass, use glass that has been pre-tested by the manufacturer
How to prepare your glass project
· Select glass that is “tested compatible” and has the same COE (Coefficient of Expansion) for the entire project.
· Glass projects should be comprised of two or more layers of glass from edge to edge because at a full fuse, glass likes to be approximately ¼” (6mm) thick. The best designs are constructed using a single piece of glass for the base piece, with a cut design as the second layer. If you’d like you can add more detail to your design with frit, stringers, and confetti. During assembly, take the time to make sure your glass pieces fit well together. If necessary, use a glass grinder to aid with the fit. A helpful tip to reducing and eliminating grinder marks from showing up in your fused pieces is to use an extra fine grit grinder bit.
· Oil from your glass cutter, as well as oil from your fingers while handling the pieces, is left on the surface of the glass. Thoroughly clean your glass pieces with either a light detergent, like Dawn dishwashing detergent, and water or with denatured alcohol. If you did any heavy grinding, also use a soft bristled brush, like an old toothbrush, to scrub the edges and remove any residual ground glass debris. After the glass had been cleaned and dried well, only handle it by the edges when assembling your project.
· To make transporting your project between your workspace and the kiln easier, you can use water soluble glue. Use glue very sparingly on the backside of the glass. Allow the glue to completely dry before you try to move your piece.
· Before setting up your glass projects on the kiln shelf, first place the kiln shelf in the kiln. If you are planning to fire more than one piece at a time, make sure to position your glass projects no closer than ¾” to 1″ to each other and also no closer to the edge than ¾”.

Firing your Glass Project

When you first start fusing, the entire process may seem to be complicated, but it’s really simpler than it may have originally sounded. Fusing is all about controlled heating and cooling of glasses in a kiln. As glass is being fired in a kiln it goes through many physical changes based on the temperature zone that it’s in.

· Below 1000°F (538°C), glass is very rigid and is very susceptible to thermal shock, or breaking, if heated or cooled too quickly. Visually, the glass appears to be very rigid and it will look the same as if it were room temperature. Resist the temptation to open the kiln and peek inside, because glass is very fragile at this point and large temperature swings in the kiln will cause the glass to break.
· Between 1000°F and 1250°F (538°C ­ 677°C), the glass is softening, becoming more pliable, and starting to act more like a liquid and less like a solid. At the top end of this temperature range, glass will slump if held for a period of time. Visually the top layer of the glass will begin to soften and round over on the edges and the sides will start to become wet and glossy looking, or fire polished. At this point, the layers of glass haven’t begun to stick together yet.
· Between 1250°F and 1350°F (577°C – 732°C), the glass is becoming even softer, and at the top end of this range will be fully slumped. It’s not recommended to exceed 1350 F if you are slumping because at higher temperatures, there is a loss of control of the glass and it may slide down too far or unevenly into the mold. Visually the edges have softened and rounded even more and the surface is very glossy. If your project is held for an extended period of time in this temperature zone, it will be more prone to devitrify. Devitrification is the compositional change of the glass from an amorphous material to a more crystalline structure. As the molecules crystallize, devitrification appears to cloud the surface of the glass.
· Between 1350°F and 1400°F (732°C ­ 760°C), the glass will have very round edges on the surface and will stick together and become fully tack fused.
· Between 1400°F and 1500°F (760°C ­ 816°C) the glass becomes more fluid and fully melts together at the higher end of this temperature range, which is a full fuse.

Firing Process

In fusing, the fired appearance of the glass is referred to as the firing process for the purpose of a selecting a firing schedule.

Full Fuse:

The glass has been completely melted together into one solid piece of glass that is smooth on the surface and all of the edges are well rounded.

Tack Fuse: Glass has a textural feel on the surface. All the edges of the surface pieces are well rounded and fully attached to the base glass.

21

Slumping:

AF4X Kiln Controller
The glass has been placed onto a mold and bent to shape and conform to the mold.

Fire polish: All surfaces of the glass have been fired to a glossy finish, yet the outside edges of the piece are crisp, clean, and somewhat square.

Firing stages
Initial Heating from Room Temperature (room temperature to 1200°F range): During the initial heating, the glass is very brittle and susceptible to breaking (thermal shock) if it’s heated up too quickly. During this stage, it’s best to take a conservative approach and slowly heat up the glass. At the end of this range, it’s a good idea to add a heat soaking period to allow the project to equalize to the same temperature throughout. Never peek in the kiln during this stage, or you risk thermal shock breakage.
Process Heating (1200°F to 1500°F range): The glass becomes softer and more fluid. During the process heating stage, the glass can be fired more quickly to the target temperature and soaked only long enough to achieve the desired look. It’s important not to hold the project at these temperatures for a long period of time, or you run the risk of devitrification (a visible clouding of the glass surface due to crystallization).
Fast Cooling (1500°F to 1100°F range): After the finished look has been achieved, it’s important to cool the inside of the kiln and the glass as quickly as possible to stop the firing action so that it “freezes”. During the fast cooling stage, the surface of the glass is cooler and it has contracted more than the heated center which remains expanded, thus introducing stress into the glass piece.
Annealing (1100°F to 700°F range): At the beginning of the annealing stage, it’s necessary to heat soak the glass for an extended period of time to allow the glass to equalize in temperature throughout and release the stress that’s in the glass. This makes the glass more stable. Then the glass is slowly cooled through the annealing temperature range to better ensure the glass piece is free of internal stresses and is physically stronger. NEVER OPEN THE KILN DURING THIS STAGE!
Cooling to Room Temperature (700°F to room temperature range): After the glass temperature has cooled below the annealing temperature zone, the kiln can be turned off to allow it to cool at it’s own pace to around 150°F ­ 200°F. Again, to avoid thermal shock, do not open the kiln until it has cooled down to at least 200°F. Even at this temperature, the glass is very hot, so do not attempt to pick it up in your bare hands. Simply open up the lid of your kiln and allow the glass and the kiln shelf to cool down to room temperature.
Factors to consider before selecting a firing schedule
First envision what you want your finished piece to look like and ask yourself the following questions:
22

AF4X Kiln Controller
· What is the size (diameter) of the piece? How many layers thick will it be? · What is the desired finished look? · Will it be a full fuse, a more textural tack fuse, a combination of both? · Will it be slumped or draped to become a more 3 dimensional and possibly functional piece? · Will it be embellished with any surface decorations like enamels or metallic paints?

The size of your project is defined by both the diameter of the piece as well as the number of layers of glass. Glass as a material is a very poor heat conductor. The larger or thicker your project is, the more slowly it needs be fired so that the glass has more time to heat or cool evenly all of the way through.

Imagine that you are going to bake a cake. You have set your oven on preheat to heat it up quickly, put the cake into the oven to bake, and forgot to change the dial setting to bake. When the timer goes off, you look in the oven and discover that the cake is overcooked and possibly burned on the edges, yet the center is still sunken and uncooked.

It’s just the same for glass. If you heat the glass too quickly, the edges may be fused to the desired finish you like, but the center hasn’t finished fusing. One solution would be to soak the piece at the process temperature for a longer period of time, but you are also taking the risk that devitrification (visible
clouding due to crystallization) on the surface or that the edges will over fire and have an unusual
appearance.

Another possible scenario is that the edges of the glass have melted more quickly, trapping a large amount of air in the center of the piece which expands into large bubbles within the glass, thus distorting the design.

Both scenarios could have been avoided simply by slowing down the firing program.

Think about your finished piece again. You are creating a 10″ bowl that will have a full fused appearance with some added textural design elements that will be added using liquid stringer. The finished appearance will also have Hanovia gold added as accents and be slumped into a 10″ bowl mold.

Seldom can a fused piece be finished in one firing. It’s usually necessary to fire your piece multiple times in order to achieve the finished look that you have envisioned. With this in mind, make a list of the steps that you will need to do to create this piece, then organize them in order by process temperature from the hottest to the coolest.

bEAd Program Mode
The bEAd mode provides 4 preset firing schedules for bead annealing and 4 optional User Programs for creating custom firing schedules. The 4 preset programs are recommended firing schedules that can also be customized if necessary. These programs provide the various heating and cooling steps for easy selection.

Ramp and Holding Working Programs are useful while beading and lampworking. When the program is started the kiln heats fast and then holds at an annealing temperature for the longest amount of time that is planned to work. In this case 4 hours and if the time to work suddenly becomes less, then use skip step feature (sstp) (the middle button once and the left button twice) to advance the segment of the program. This segment has the same annealing temperature to hold so that the last couple beads have a chance to anneal for a time before the kiln proceeds to lower in temperature at 100 degrees.

RECAP: If you plan on working for 8 hours making beads and you need to stop after 5 hours, then skip step will advance you to the next segment so that the last few beads inserted into the kiln will have a chance to anneal before the kiln starts to cool.

FIRING METAL CLAY

Drying Time
Allow your pieces to be completely dried before firing them in the kiln to ensure that they don’t warp.
Loading the kiln
If you fire both glass and metal clay in your kiln, it is recommended that you invest in a second shelf so that you can fire only glass on the glass kiln shelf, and only metal clay silver on the other kiln shelf. After firing your PMC piece, some of the metal particulates impregnate the kiln shelf and leave stains on the shelf’s surface. If you fire glass on the very same shelf, there is a chance that glass and metal may have a reaction that will result in silver stains left permanently on the glass. Pieces that have a flat side can be placed directly onto the kiln shelf. They can be positioned closely together, but they shouldn’t touch. Pieces that are rounded, hollow or very delicate in composition will need support while firing so they don’t collapse. Pour alumina hydrate or vermiculite into an unglazed ceramic bisque bowl and carefully place the metal clay pieces onto the alumina hydrate/vermiculite. Again, they can be positioned closely together, but they shouldn’t touch. Begin in the IDLE mode To begin programming the kiln, it must be in the IdLE mode. This can be determined by viewing the LED display. The display will alternately display both the current temperature and the IdLE message. When the kiln controller is first turned on, it will display the current firing configuration that it is in. Press (Program) button to return to the IdLE mode.

Once the kiln has completed firing, the display will show CPLt and this message will alternate with the temperature display and the total firing time from start to finish. DO NOT open the kiln until it has completely cooled and the temperature shows room temperature.
User Programs
25 User Programs are available. The User Program mode allows you to customize your firing schedule and specify how fast the kiln heats or cools to any temperature. All Programs allow 20 ramp steps. Each ramp step consists of a heating rate (or cooling rate), a target temperature and a hold time. Temperature Units If your controller is configured to display temperature values in F, heating rates will be programmed as Degrees Fahrenheit per hour and target temperatures will be programmed as Degrees Fahrenheit. If your controller is configured to display temperature values in C, heating rates will be programmed as Degrees Centigrade per hour and target temperatures will be programmed as Degrees Centigrade. To change the temperature units, see the F/C option.

Heating/Cooling Rates

AF4X Kiln Controller

Each program step requires you to program the desired rate value.

Rate is the speed of the ramp step. Rate is programmed as Degrees per Hour if the RATE option is set to HOUR. Some calculations may be required to determine your desired heating rate.

Example; if you know that you want to heat the kiln from room temperature (75F) to 212F over a 2-hour period, First determine the amount of temperature rise:

212 – 75

=

137 degrees

Then divide the amount of temperature rise (or drop) by the number of hours you would like it to take to get there. (For Example, 2 hours)

137 2

=

68.5 degrees per hour

Round the calculated rate to the nearest whole number and your heating rate would be 69 degrees/hour.

If you prefer to program heating and cooling rates in degrees per minute’, adjust the RATE option in the options menu to MIN. If you prefer to program heating and cooling rates inHours and Minutes’, adjust the RATE option in the option menu to TIME.

RA is the controller display for rate. Each rate segment will have its own number. The rate for the first ramp step
will be displayed as RA 1, the rate for the second ramp as RA 2 and so on. Maximum Ramp Rate for User Programs The range of values available for a controlled ramp rate setting is 0-1798F per hour or 0-29.97F per minute. To program a rate that heats or cools as fast as possible, Set the rate to FULL. FULL appears as a selection for 1799F/hour or 29.98F/min. Just above the maximum ramp rate. You can also find the FULL setting by pressing the decrease/review button one time when the display shows zero for the rate setting. When the RATE option is set for TIME, the maximum ramp rate or FULL setting is 00.00, the range of controlled rates is 00.01 (1minute) to 99.58 (99hours.58minutes) When the Ramp Rate is set to FULL the controller will interpret this as full power for a heating ramp. This will allow the kiln to heat as fast as possible to the target temperature without rate control. If the ramp is a cooling step, the controller will interpret the same values as no power and allow the kiln to cool as fast as possible without rate control.
A Program Review will show the message FULL to indicate the uncontrolled rate. Deviation alarms will not be active during the heating/cooling ramp.
Caution: Overshoot in temperature may occur when a kiln is heating at full power, especially at lower temperatures.
Target Temperatures Each program step requires you to program a desired target temperature.
F or C is the controller display for target temperature. Like rate, each temperature segment will have its own
number. The temperature for the first ramp step will be displayed as F 1 or C 1, the temperature for the second ramp step as F 2 or C 2 and so on.
29

AF4X Kiln Controller
Caution: Do not program target temperatures that exceed the temperature rating for your kiln. The maximum programmable value for target temperatures can be viewed in the SFTY option.
Cooling Ramps
Cooling ramps are programmed the same as heating ramps. You must program the Rate for the cooling and the target temperature. The criteria for a cooling ramp is the target temperature must be lower than the preceding target temperature.

If you program a target temperature at the end of the firing that is below your room temperature, the controller will never be able to complete the firing. This may result in an FTL alarm. To avoid this alarm, manually stop the firing by pressing the Program/Stop key or program a higher temperature to complete the firing
Changing a Target Temperature During a Firing
If the kiln is firing and you need to modify the current ramp target temperature, use CHGT option. The controller will display the current setting and allow you to change it. See the Option menu section of this manual for more details.
Hold Time
Each program step requires you to program a desired hold time.
Hold time refers to the amount of time you want the kiln to remain at the target temperature. Hold Time is often referred to as Soak or Dwell Time. Each ramp allows the option of programming a hold time. Hold time is programmed in Hours and Minutes. The decimal point light in the center of the controller display separates hours from minutes. The two digits to the left of the decimal point indicate hours while the right side indicates minutes.

Example;

A 1 hour hold time should be programmed as

01.00

or A 30-minute hold time would be

00.30

During a Hold time, the controller will count-down the remaining time of the Hold on the display.

HD is the controller display for hold time. Each Hold segment will have its own number. The hold time for the
first ramp step will be displayed as HD 1, the hold time for the second ramp step as HD 2 and so on.
Set-Point Hold You can program the controller to hold at a temperature indefinitely by programming a Hold Time of 99.59. The controller will hold the kiln temperature until the Program/Stop key is pressed.
Adding Time to a Hold If the kiln is firing and you need to increase the hold time, use the HLDT option. The controller will display the current setting and allow you to change it. See the Option menu section of this manual for more details.

Shortening a Hold To end a hold before the time has expired, use the SKIP option to advance to the next ramp. See the Option menu section of this manual for more details.
30

Vent Fan (Optional)

AF4X Kiln Controller

If your controller has been configured to control an auxiliary vent fan, each ramp step will allow the fan to be turned on or off during the specified ramp. Refer to the Options section for additional details on the AOP1 output.

FN is the controller display for vent fan. Each ramp will have its own fan setting. The fan setting for the first
ramp step will be displayed as FN 1, the fan setting for the second ramp step as FN 2 and so on.

Programming User Programs
During programming, default values may appear in the display. If the controller was previously programmed, the last settings will appear.

1. Press the Program/Start key. A program group will show on the display.

2. Press the Increase/Option key until the display shows USER, then press the Program/Start key.

3. Using the Increase or Decrease key, select the desired program number (PR01-PR25) then press the Program/Start key.

Test Firing with Witness Cones

A test firing will help in learning the operation and features of the controller. Place a series of Orton SelfSupporting Cones on the middle shelf of your kiln so that they can be seen through a kiln peephole. Use a series of cones close to the final firing temperature (see Appendix C). For example, if firing to 1945F (Cone 04), use a Cone 03, Cone 04, and Cone 05 for the test firing.
To evaluate heat distribution, place a set of cones on each shelf during the test firing. Most kilns fire more uniformly at Cone 06 than they do below Cone 06. Provide ventilation for the kiln in accordance with the kiln manual or Vent Master® instruction manual.
After the firing, examine the fired cones. Some variation in the bending of the cones may occur, depending on how the kiln was loaded and the location of the cones.
Cone-Fire ­ How it works
When firing to a cone number, the controller constantly monitors the actual heating rate of the kiln. If the kiln does not fire as rapidly as programmed, the controller re-calculates and adjusts the top firing temperature to compensate for the slower firing rate. This process more accurately fires to the cone number selected. When the heating rate slows, cones deform at slightly lower temperatures. At faster heating rates, cones deform at slightly higher temperatures. This ability to recalculate and to fire to a cone value is a unique, patented feature of all Orton controllers.

Orton Controllers contain three preset program groups for firing to a cone number ­ Low Fire, Mid Fire, and High Fire. Each of the programs can be adjusted for speed, hold time and cooling rate. The standard programs are designed to fire normal loads of thin ware ceramics. When a kiln is more heavily loaded or when thick ware is fired, additional firing time is needed. Experiment to determine the best firing conditions. The preset firing programs in the controller are:

Program Low Fire Mid Fire High Fire

Product Fired Decal, Luster, China Glaze, Bisque, Earthenware Stoneware, Porcelain

Cone Range Cones 022 ­ 011 Cones 010 – 01 Cones 1 ­ 10

Keeping a log

AF4X Kiln Controller

There is no “one program fits all” firing schedule for kilns. Even supposedly identical kilns behave slightly differently. Plugging the same kiln into different outlets in your house may also alter the firing schedule you need. Additionally, different size projects or different colors of glass will react differently, necessitating changes to your firing schedules. It is therefore very important for you to keep detailed firing logs whenever you do a new project or change any parameter in an existing project.

As you gain experience using your kiln, you may find that you need to use the “add hold time” or the “skip step” sequences to get exactly the results you want. If this is consistently the case for your particular project, you may want to generate a user program, written to your desired specifications or modify one of
the pre-programmed firing schedules.

Alarm Display Codes

Alarms are used to notify the operator of problems with the kiln performance or controller performance. Some alarms will terminate the kiln firing while others allow the firing to continue with the alarm condition on the display. Some alarms have no effect on the outcome of the kiln firing.

Appendix B ­ Mid Fire Cone Programs
Cones O10 to O1
This firing range is used to fire earthenware and low temperature glazes. If the ware is not thoroughly dried, a preheat cycle can be added. With lead-free glazes, a 10 to 20-minute hold is beneficial.
Earthenware or other bodies containing ball clays, talc, and kaolin contain compounds such as water, carbon, and sulfur that are burned-off during the firing. The body will lose about 10% of its weight. In addition, a physical change in any silica present can cause cracking of ware unless the heating rate is slowed near 1063F (573C). This change occurs during both heating and cooling.
The complete firing schedules for Cones O10 to O1 are shown below. The standard firing time is about 7-9 hours.

Appendix C ­ High Fire Cone Programs

Cones 1 to 10

The firing range of higher temperature bodies, such as stoneware and porcelain vary between Cone 4 and Cone 10. These bodies are fired nearly to vitrification and can shrink up to 16%. As with earthenware bodies, water, carbon, and sulfur are potential burnout materials and venting is important to remove gases generated. With the presence of silica, the firing needs to be slowed near 1063F (573C) to prevent cracking.

Typical porcelain bodies are formulated from kaolin, feldspars, silica, and ball clays. The weight loss during firing can be around 10 to 12% and shrinkage can approach 20%.

Porcelain bodies require good temperature uniformity at their final firing temperature. If slightly overfired, the body may warp or blister. On maturing, the body becomes its own “glaze.” A hold time is usually desirable for best fired results.

The complete firing schedules for Cones 1 to 12 are shown below. The standard firing time is about 1012 hours.

AF4X Kiln Controller
The JEN-KEN SAMPLE PROGRAM THAT YOU CAN ADD IN THE USER MADE AS NEEDED.
The new AF4X controller software has undergone a major software update! The controller contains several sets of preset programs. Jen-Ken Kilns and Orton have produced the most user friendly and powerful, kiln controller for artists. If the Jen-Ken Kiln can perform all the above tasks then all of the above settings will be turned on. The Chilipepper is a low firing annealing kiln and will only have the ­BEAD- setting turned on. The AF3P Bead Annealer with flip door will have all of the above turned on except the Clay and Cone feature because the kiln cannot fire that hot. Program sets include: LP (Large Pieces) ­ SP (Small Pieces) ­ CLAY (PMC) ­ CONE (Ceramic) ­ BEAD – USER (custom) There are 25 User Programs available if you switch modes to the USER program set. The User Program mode allows you to customize your firing schedule and specify how fast the kiln heats or cools to any temperature. All 25 programs allow 20 ramp steps. Each ramp step consists of a heating rate (or cooling rate), a target temperature and a hold time. Once programmed they remain in the controller memory until you chose to change them. Here is a list of 25 programs created by us to assist you as you learn and grow as an artist! You can alter and change these programs as you progress as an artist. Once you program these schedules, they will remain in the USER program set of the controller memory until you chose to alter them.
Program 01 is a full fuse for pieces smaller than 10 x 10 and program 02 is a full fuse for pieces larger than 10 x 10.
Program 03 is a contour fuse for pieces smaller than 10 x 10 and program 04 is a contour fuse for pieces larger than 10 x 10.
Program 05 is a tack fuse for pieces smaller than 10 x 10 and program 06 is a tack fuse for pieces larger than 10 x 10.
Program 07 is a fire polish for pieces smaller than 10 x 10 and program 08 is a fire polish for pieces larger than 10 x 10.
Program 09 is a slump program for pieces smaller than 10 x10 and program 10 is a slump program for pieces larger than 10 x 10.
