ble. The temperature of a cone varies with firing
speed. The cone temperatures in Cone Table are
for self-supporting cones fired at a rate of 108°F /
60°C per hour during the last hour of firing.

Skip Segment Examples
For additional examples, see Chapter 4, pages 14 - 15.
Cone-Fire
■
In Cone-Fire you are firing to an 05 witness cone for the
first time. You select cone 04 with a 60 minute hold and a
slow cooling. After 30 minutes in hold, the 05 witness
cone bends to maturity. Use Skip Segment to end the
hold and begin Slow Cooling.
Note: Once you know how much hold time will
bend the witness cone, program that much hold for
the next firing.
Ramp-Hold
■
Skipping to a Cooling Segment: You have programmed
2167°F fora cone 5glaze firing, followedby a segmentfor
controlled cooling. Watching the witness cone through
the peephole,you notice thatcone 5 is bending at2150°F.
Use Skip Segment to end the firing segment and begin
the one for slow cooling.
Note: Make a note of the temperature at which the
cone bent. Program that temperature for the next
firing.

Skipping to a Hold: Skip Segment does not skip from a
ramp toa hold.It skipsto thenext segment. Ifyou needto
skip to a hold, program an additional segment with the
holdthat youwant. Thenskipto thatsegment.Example:
