CONE FIRE Programming
This is the quickest and easiest method to program the controller to fire ceramics. Programming
consists of choosing the firing speed and entering the clay or glaze’s cone number. The firing speed is
chosen by the type of firing and thickness of the clay. The bisque firings include water smoking and
carbon burn-out stages. The glaze speeds allow for faster firings. All 4 speeds will calculate the firing
rate at the end of a firing and adjust the final temperature for correct heat-work. Follow these few steps to
enter a cone fire program.
Press
Slow Bisque
Display shows
S-bC
The slow bisque speed is used for thicker hand thrown ware. The
slow speed gives extra time for release of water and carbon burn-out.
Typical firing times range from 13-17 hours depending on the cone #.
Hand built pieces may need a preheat stage.
OR
Fast Bisque
Display shows
F-bC
The fast bisque speed is for thinner ware that requires less time for
water smoking and carbon burn-out. Firing time is 9 – 11 hours,
typically, and depends on the cone number.
OR
Slow Glaze
Display shows
S-GL
Slow glaze is used for firing glaze on thicker ware or for bisquing
very thin ware. Typical firing time is 6-8 hours depending on the
cone number.
OR
Fast Glaze
Display shows
F-GL
Fast glaze is the fastest speed and is used for glaze firing on thin ware,
china paint firings, and decal firings. Firing times range from 4 to 5
hours

CONE/xxx
The displayed firing speed was accepted and now the controller is
waiting for the cone number to be entered. The x’s represent the cone
number last selected.
Press
Number keys for
cone number

Use the number keys to display a new cone number. Remember, cone
numbers starting with a 0 are lower temperature than cone numbers
not starting with a 0. For example, don’t mistake a cone 6 for a cone
06!
Press
ENTER
Display shows
HOLd/0.00
The displayed cone number was accepted and now the controller is
waiting for the hold time at the top temperature to be entered. Usually
this value is left at 0. If a time is entered the hours are to the left of
the decimal and the minutes to the right.
Press
ENTER

Display is back to Idle
Zero hold was accepted and programming is complete.
NOTE - A preheat segment for drying (candling) ware can be added to any cone fire program. See
options
section for PREHEAT instructions.
TEMPERTURE REACHED at the end of a cone fire program:
When the display is at IdLE, pressing Review Program, will show the heat-work adjusted temperature that
was reached. The temperature is displayed after
o
F in review program. This temperature will remain until
the controller is reprogrammed. Record this temperature in your log after each cone firing.
