Place the pottery in an electric kiln. Raise the temperature of the kiln to 850 degrees for 12 hours. This will produce "bisque" or "unglazed pottery." This initial firing removes the physical and chemical water so that the piece can be glazed without returning to mud and breaking. Ranges of temperature are referred to as "cones" in the ceramics world.[2]
Allow the temperature to drop and remove the pottery 48 hours later after the temperature has completely cooled.
