Electric Kiln Bisque Firing Schedule

There are two main approaches to bisque firing.

Electric kiln bisque firing schedule.

For a bisque firing there will be no soak and the ramp the increase in which the kiln s temperature is changing should be very slow. The heat will be applied just enough to slow the cooling. Bottom switch on low for several hours if necessary candling. Without it organic and sulfur compounds won t burn off and can then cause faults in a later glaze firing.
