Cone Fire–Fast
Fast is a speed that will take approximate-
ly 4 hours* firing depending on the cone
selected. Fast speed is probably not the
best choice to use during a bisque firing as
it does not allow enough time for the
physical water to burn off and the struc-
tural changes to occur. If you were to pro-
gram the segments for this firing, they
would look like the chart at right:
The graph at right illustrates the seg-
ments of a cone 04 firing in Cone Fire
mode, fast speed. The firing will take
approximately 4 hours to complete.
If Review is pressed near the end of the
firing (within one hour of completion) an
adjusted cone temperature of 1937˚ for
Cone 04 will be displayed. For more
explanation, see Appendix 2, Cone Chart
and Heat Work. This section explains why
the end temperature may be higher or
lower than the cone table indicated.
*Firing times are approximate, based on a
beginning temperature of 70˚F/21˚C firing to
Cone 04.

Messages and prompts in the Cone Fire
Mode.
A word about the funny digital characters:
they may seem unreadable now, but
you’ll get used to them.
PF
Power Failure, may indicate that the
controller was just plugged in. Press Enter
to clear the PF message and display inter-
nal kiln temperature.
HOLd
Hold time desired at end of firing
is entered in hours and minutes up to a
maximum of 99 hrs. 99 mins. To enter,
numbers on the right of the decimal are
minutes, to the left are hours. The default
setting is 00 hrs. 00 mins.
ConE
Requests firing cone number. Be
sure to enter the correct number keeping
in mind that cooler firing temperatures
have a “0” in front of the number.
SPd
Requests the speed of firing, either
slow, medium or fast.
IdLE
When idle is flashing alternately
with the internal temperature of the kiln,
the kiln is in IDLE MODE and ready to
pregram.
