KilnZone Rules

1) I3 KilnZone training is required to operate KilnZone equipment. A list of Trained Users is below.

2) When not firing, all private materials and components need to be removed to member's storage. The metal rack is for PUBLIC materials only.

3) Use Boron Nitride for public molds. Use Kiln paper for Kiln floor.

4) Clean or apply KilnWash or Boron Nitride OUTSIDE. No Exceptions. ALWAYS use a mask.

5) When using glass powder and other materials of 100 Micron or less, use a mask. And don't work near other people. (Farther than 20' and near ventilation if possible).

6) Do Not open a working Kiln unless you are the current user or there is an emergency.

6) If you are using a Kiln and need to leave the building, Make sure Your name and cell # is on the KILN IN USE Whiteboard and the Kiln In Use Side is outward.

7) Do not put cardboard or paper in the cage. Plastic is OK if more than 18" from the Kiln.



1) If needed call 911.

2) If possible and effective, turn off Programmable Controller with green switch.

3) Else, if possible turn OFF Kiln 1 by turning all 3 knobs on Kiln 1 to ZERO. You should hear a click and see the red light go out.

3) To contain fire, if necessary, use the fire extinguisher located at KilnZone.

4) Call current user at the cell number located on the clip board on the gate of the KilnZone.

How to Program the Kiln Controller

Ver 1.0

by Terry W.

Step 1) Turn ON controller with Green button. You should see the current temp in PV display.

Step 2) Push the SET button. You should see PASS in the PV display and 0000 in the SV display.

Step 3) Our convention will be > for the rightward arrow button, ^ for the upward and v for the downward, since I can't type that one. Use >, ^, and v to type in 2000 and hit SET.

Firing Schedules.

You will see in books on glass, things called firing schedules. They look like this:

You read that as a set of instructions:

Ramp up the temperature from room temp to 1250F at a rate of 300F per hour.

THEN hold 1250F for 30 minutes.

THEN ramp from there to 1420F at a rate of 300F per hour.

THEN hold it for 30-60 minutes.

THEN ramp as fast as you can from there to 960F

THEN hold it for 90 minutes

THEN ramp at 50F/hr to 800F

SKIP holding it.

THEN ramp at 100F/hr to 600F

THEN turn it OFF and don't open the kiln until Room Temp (No Venting).

Your Kiln Controller needs to be programmed in a series of steps. Each steps has 3 attributes, C,T,Sv. So your list of instructions will look like







Let me define what each of those are.

C is the PID setting we use. We always use PID#1, which I have preprogrammed into the controller. Please do NOT change PID#1.

T is time, in minutes. More later.

Sv is a target temperature in F. I believe Sv is short for “Set Value”. And Pv is Present Value....of what you are trying to control, in our case Temp F.

So from our example

C1=0001, T1, Sv1=0070 (room temp)

C2=0001, T2, Sv2=1250

Now Let me explain what T is. T1 is supposed to be the time (in minutes) we are telling the controller to get from Sv1 to Sv2.

So our programming looks like this:

C1=0001, T1=240, Sv1=0070 (room temp)

C2=0001, T2=30, Sv2=1250

C3=0001, T3= 60 , Sv3=1250




Note that I am rounding to the nearest half hour because kiln work isn't that fussy ...until you get to Pate de Verre, which is not covered in this lesson.

Once you have put in all steps, scroll up to END and hit SET. This enters your program. The controller will keep it, even if switched off.

Once programmed, you can

1) Make sure the Thermocouple (yellow plug) is plugged into the yellow socket (check polarity).

2) Make sure the data signal (blue cat5e wire) is plugged into the Controller and the Relay Box.

3) Make sure the Relay box is plugged into the wall and the circuit breaker is set to ON.

4) Roll the cart OUT of the cage.

5) Make sure the top of the kiln is plugged into the bottom.

6) Make sure all 3 knobs are set to 10 (or to 11 if you are a Spinal Tap fan).

7) Make sure the Kiln is plugged into the Relay Box.

8) Turn on the Controller with the Green Switch.

9) Hit the > key and you ???
