begin firing, taking up where it left off.

maturity, and thetemperature drops 50°F/28°Cor more after
the kiln shuts off, do not depend on the pyrometric witness
cones in the kiln. Once the cones cool 50°F/28°C after they
have been heated to within 100°F/55°C of maturity, they will
not bend properly. This is because they form a hard shell.

Ceramic Cone-Fire
Cone-Fire mode is based on pyromet
-
ric cones. It is not designed for heat treat
-
ing, glass fusing and enameling. For these
firings, see “Ramp-Hold,” page 9. Use
Ramp-Hold to fire ceramic pieces that re
-
quire a custom firing schedule, such as
some types of stoneware sculpture or crys
-
talline glaze. To fire faster than Cone-Fire
Fast speed, use Ramp-Hold.
Do NOT use Cone-Fire until you have
read “Cone-Fire Basics” and “Cone-Fire
Programming.” To take full advantage of
other features in Cone-Fire mode, read
“Advanced Cone-Fire,” pg 8.
Cone-Fire Basics
Firing Speeds
Cone-Fire operates in Fast, Medium or Slow speed. The
instructions that follow will show you how to select speed.
To view the firing segment of a cone-fire, press 5 during
