Counterintuitively in low fire the cone number is higher up to 04 to ensure that all the carbon and other materials in the clay burn out during the first firing. Bisque firing schedule for automatic kiln controllers see above electric kilns with automatic controllers break firings down into ramps or segments of heat increase or decrease and the readout has abbreviations that correspond to different factors controlling the temperature rise per hour top temperature in each segment and thus the. The firing schedule for bisque firing is extremely important. Bottom switch on low for several hours if necessary this is called candling.

Turn all switches to high until kiln has reached temperature. The ramp rate is usually measured in degrees per hour. 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. Turn all switches to medium for 3 4 hours.
