About this Item

This kiln was donated to Hive13 by a gold and silversmith who used it for enameling and wanted to help spread the art to new people. It was in very poor condition on arrival, all fasteners were heavily rusted, the kiln floor and walls were heavily erroded and contaminated with enamel, and the case and electrical cabinet were covered in a thick layer of dirt, dust, and rust.

It was originally a Thermolyne Type 6000 Kiln (Model Number F6020C), with a very basic single-temperature temperature controller.

A member vote was passed in Summer 2021 to purchase a programable ramp/soak controller similar to the one on our Paragon SC2 kiln so that this kiln could be used for more activities that require programable function, like ceramics, glasswork, and wax burnout for casting.

While installing the new temperature controller (Fall 2021), Kevin decided the kiln really needed to be thoroughly cleaned and refurbished. It was fully disassembled, the case blasted and painted, all screws, washers, and nuts replaced with stainless steel hardware, and reassembled. The Rebuild was finished on November 16th, 2021.

From the Manufacturer: "Features an 860 cubic inch heating chamber, width 12 3/4 inches wide x 6 3/4 high x 10 inches deep. Embedded heating elements provide uniform chamber gradient. Maximum operating temperature is 1093°C."

The model we have is designed to draw 18.3 amps at 240vac (4400W). Real measurements put the actual current draw closer to 19.3 amps, with the receptacle in hot crafts measuring 246 vac, for a total power closer to 4750W.

Starting A Program

  1. Check if it is on already and if it is in a cycle. If cycling, let it finish. DO NOT OPEN THE ANNEALER IF IT IS CYCLING, ANNEALING GLASS. Opening the annealer at any time it is not holding the loading temperature for loading or cooled to below 125F will cause the glass in it to crack. If off, or cycle is complete and temperature has reached under 125F, empty the annealer of any annealed pieces.
  2. If off, flip switch up to turn on. wait for the temperature controller to boot up and the display to reach a stable rotation of information. If it says anything other than Idle/<Current Temp>, press the Program/Start/Stop button till it says Idle/<Current Temp>.
  3. Press the Program/Start/Stop button to enter the program group list.
  4. Press Up Arrow/Increase/option button to scroll through the program groups (USER has our custom programs in it, like for glass, read the controller manual for the others). Only the up arrow may be used to scroll through the list, if you go past the program group you need, just keep scrolling up till it comes back around.
  5. Press the Program/Start/Stop button to select the program group and view the list of programs in that group.
  6. Press Up Arrow/Increase/option button to scroll through the available programs till the display shows the program you want.
    1. USER/PR01 is programmed for Garaging and Annealing Soft Glass
    2. USER/PR02 is programmed for Garaging and Annealing Borosilicate Glass
  7. Once the desired program is located, press the Program/Start/Stop to enter the "Program" mode for that program. Continue to press Program/Start/Stop to step through all the steps of the program without changing the parameters. Once you have stepped through all the programmed steps of the program, the controller screen with show START.
  8. Press the Program/Start/Stop again and the controller will ask for the DELA (Delay) time to start the program, if you wish to delay the start (like for a wax burnout to be finished at a specific time), use the UP and DOWN arrows to set the delay time (time in HH:MM to starting the program).
  9. When you have set the desired delay (or zero delay), press Program/Start/Stop to start the program.
  10. The display should show “-ON-” and the run light should start blinking (if not, Press the Start/Stop/Enter/Program button again). In a few moments the red light below the controller should turn on indicating the annealer is heating.
  11. While running, the display will indicate the current temperature of the annealer.
    1. If loading torch glass - Do not load any glass in the annealer until it reaches at least 925F. Loading glass in the annealer at less than 925F can cause it to crack.

Starting Annealing For Glass Programs

When you are done making and loading glass pieces, and ready for the annealing to begin, you must skip the infinite hold that is programmed in for garaging/loading.

  1. Press the Up Arrow/Higher button till the "SStp" (Skip Step) option appears on the screen.
  2. Press the Start/Stop/Enter button to select the "SStp" (Skip Step) option.
  3. The screen will display "Hld1", press the Start/Stop/Enter button to confirm you want to skip step Hold 1
  4. The screen should now no longer be flashing between a temperature and "99:59" as it was during the infinite hold garaging step, instead it will display the temperature and begin to ramp up the temperature to the annealing temperature. Once the annealing temperature is reached, it will begin to flash between the current temp and the remaining hold time (starts at 1 hours and counts down).
  5. The full annealing cycle takes between 2 and 3 hours to run, and then an additional 2-3 hours for the kiln to cool to unloading temperature (below 125f). Do not open the kiln till it reaches unloading temperature (below 125f).


Maximum Heat & Cool Rates

The charts below show the maximum heating and cooling rates for different temperature ranges based on preliminary testing. Programed rates must fall within these limits or the controller will enter an alarm state for "Failure to Heat" (FTH) or "Failure to Cool" (FTC).
