Revision as of 20:56, 22 December 2016
The Jewelry and Metal Craft Shop currently has two small kilns. One is owned by TinkerMill (gray) and one is personally owned and used for specific classes (while). Both are programmable. To use or for questions about the white one, please contact Sarajane Helm (sarajane.helm@tinkermill.org)
The gray kiln is a Satellite Manufacturing Co. J-100. Tinkermill modified it to add a programmable controller similar to the Advanced Temperature Controller, Ramp and Soak Controller (User Manual for Controller)
What follows documents the heat profiles that have been programmed and the basic programming steps. Temperature settings are in Centigrade unless otherwise noted.
(Accurate as of Dec. 22, 2016)
- STEP 1: Plug directly into wall outlet capable of handling 120V @ 14A as spec'd.
- STEP 2: Turn round knob to Hi (On)
- STEP 3: Hold down the STOP button for 2 seconds to stop any running process and reset the programmer. (Prior program can resume automatically when powered up.)
- Display: Left side shows current temperature in degrees C. Right side flashes between "stop" and a number indicating the first set point temperature in deg. C.
- STEP 4: depends on profile desired. See below.
_ Profile : Burn Out for burning out a wax model from an invested flask This is part of the process of Lost Wax Casting.
STEP 4: Hold down the RUN/HOLD button for about 2 seconds. -- Right display will change to "run" and then switch to the % on-time of the heater to accommodate the program. Preceding the % on-time number is either an "A" or an "M". It should be "A" for Automatic mode. If it is not, press the A/M button. It will switch it to "A".
The program does the following automatically:
- Start at room temperature (20C/68F)
- Ramp up for 5 minutes up to 204C/400F
- Soak for 60 minutes at 204C/400F
- Ramp up for 15 minutes to 538C/1000F
- Soak for 4 hours at 538C/1000F
- Stop. Cool naturally in kiln or crash cool by opening door.

Profile: Nancy's Program for Glass Annealing/Tempering
- STEP 4: Press the SET key briefly twice. The current Step number will display.
- STEP 5: Press the arrow UP key /\ to increment the Step number or the arrow DOWN key \/ to decrement it to the desired Step number.
- STEP 6: Press the RUN/HOLD key and hold 2 seconds until the right display shows "run".
The program does the following automatically:
- Start from room temperature (20C/68F)
- Ramp up for 15 minutes to 538C/1000F and hold there - display shows "hold"
- Holds indefinitely at that temperature awaiting command to continue (Allows Nancy time to load the kiln and resume program)
- STEP 7: Press the RUN/HOLD key for 2 seconds to resume the program execution. Display changes to "run"
- Ramp temperature down to room temperature (20C/68F) over a 5 hour period (= 93C/200F/hour)
