Skip Segment Example
You have pro-
grammed a target temperature of 1425°F for glass fusing,
followed by asegment for controlled cooling. Watchingthe
glass through the peephole, you notice that the glass edges
have rounded nicely at 1315°. Use Skip Segment to end the
firing segment and to begin the one for slow cooling.
Note: Make a note of the temperature at which the
glass fused. Program that temperature for the next fir
-
ing of that type of glass.
Add Hold Time
Add Hold Time adds 5 minutes to a hold. It is designed
for ceramists who watch witness cones and for glass artists
who watch the glass near the end of firing.

To stop a firing before completion, press
. will appear, alternating with total
firing time and kiln temperature.
Note: Do not be concerned if your kiln makes a
clicking sound during firing. Kilns use relays to
power the elements. The relays click each time
their electrical contacts come together.
Note: Thekiln’s actualfiring ratemay beless than
the rate you programmed, depending on the kiln
model, available voltage, and density of the load
you are firing.
When the kiln fires to completion, it will beep for 30
seconds. The display will show the following:
