Firing a Kiln with an Automatic Controller
When I fire my glaze loads I turn off my heat pump completely. Gary said even when the heat pump isn't cycling on and off, the pump still draws a lot of electricity on standby. I never realized that fact. If I had not been watching my kiln closely I never would have known about this problem; one of the benefits of having a kiln with an automatic controller. Keep an eye on how long it takes your kiln to fire even if you don't have an automatic controller. Keeping a firing log is a good idea. Firing times tell a lot about your kiln and how it is operating. Automatic controllers records and maintains a lot of useful information
I just finished a glaze load overnight and the kiln is now cooling down. I just inserted the top vent plug so the kiln can cool down naturally. I won't open the kiln till the temperature reaches 150 F. At 150 F I'll prop the lid open and remove the vent plugs to allow the kiln to cool down to room temperature. When you spend so much time making, bisque firing, glazing, and glaze firing, no sense getting impatient the last few hours. Thanks for reading and for all your comments.
