greenware, large or thick walled pieces. We recommend that most teachers use Slow Speed because
it is often hard to tell how thick the walls are in a student’s project. If you are unsure if the piece is
completely dry, use this speed.
Cone Fire – Medium
Medium Speed will take approximately 7.5
hours to fire. Medium Speed is fine for most
glaze firings. When in doubt, use the Slow
Speed.
Cone Fire – Fast
Fast Speed will take approximately 4 hours. This
speed is only recommended for items such as
lusters and decals which can handle the fast
increase in temperature.
Hold Time
HOLD is another important feature of CONE
FIRE MODE. Once the kiln has achieved its
peak firing temperature, HOLD can maintain
that temperature for a set amount of time. This
allows the user to make fine tune adjustments
to the firing process by introducing more heatwork which can help witness cones reach maturity.
Additionally, a HOLD permits the kiln to equalize temperature, allowing for even firings and firings
that fall between cone temperatures, for example cone 05.5.
CAUTION: Excessive hold time can result in over firings. A common mistake is to enter ten hours
when a ten-minute hold is desired. 00.10 equals ten minutes, 10.00 equals ten hours.
Start
Start initiates the CONE FIRE MODE firing program. If a Delay is entered, the kiln will start a
countdown from the amount of entered delay time. Before pressing START, verify that the lid latch is
engaged, and that all combustible materials are moved out of the vicinity.
Advanced Cone Fire Menu Features
In Cone Fire mode, the operator has the ability to modify the firing program. They can do this in one
of two ways. The first method allows the user to program custom Cone Fire programs. The second
involves controlling the rate in which the kiln cools down.
Writing custom Cone Fire programs
This new feature on the 700 Board allows you to utilize the cone correlation benefits of Cone Fire
Mode coupled with the flexibility of RAMP/HOLD Mode. To use Cone Correlation to calculate
your final temperature during a RAMP/HOLD program press CONE TABLE instead of entering a
temperature for your final heating segment. Input the Cone Value you would like to correlate and
Press ENTER.
Slow Cooling (Cone Fire Controlled Cooling)
COOL is a feature that allows you to add a 1-segment cooling program to the end of a Cone Fire
program. When COOL is toggled “ON”, it will prompt you to enter a “Rate”, “Temperature”, and “Hold
Time” after you finish entering the Hold Time for a Cone Fire program. This is helpful when trying to
achieve certain glaze effects. For instructions on how to use this feature refer to pages 23 thru 25 of
this manual.
