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: The kiln’s actual firing rate may be less 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:

Press 
again. (If you change your mind and don’t want to skip that segment, don’t press 
after 
appears. The firing will continue in the same segment and the temperature will appear af- ter one minute.)
Skip Segment skips to the ramp of the next segment from either a ramp or hold of the current segment. (Skip Seg- ment does nothing during the final segment. To end the fi-
nal segment, press 
.)
You have pro- grammed a target temperature of 1425°F for glass fusing, followed by a segment for controlled cooling. Watching the 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.
