When Kiln Shuts Off Too Soon

If the kiln shuts off below maturity, you can turn it back on
and keep firing. Simply program a higher temperature or hot-
ter cone. Then from

begin firing, taking up where it left off.
Ceramic firings: if the kiln shuts off within 100°F/55°C of
maturity, and the temperature drops 50°F/28°C or 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

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
firing. (See "Present Status," page 13.) The segment number
will appear (see left column in the following charts), informing
you of how far the firing has progressed.
Fast (1)
Consider Fast for overglazes, decals, china paint, or small,
thin-walled ceramic greenware.

have been heated to within 100°F/55°C of maturity, they will
not bend properly. This is because they form a hard shell.

Portable Controller (TnF II) Installation

The wall-hanging portable DTC 1000 TnF II includes a
temperature sensor called a thermocouple. Keep the thermo-
couple wire away from electrical wires. Wrapping the thermo-
couple wire around the kiln's power cord or taping it to the
cord may cause erratic temperature display.

Cone-Fire Programming
