Paint the bisque with the glaze of your choice. Apply the glaze with a paintbrush in small, smooth strokes. Any streaks will show once the bisque is baked. If you want to layer colors, bake the piece between the application of each color.
Vacuum the inside of the kiln with a soft brush attachment. Don’t touch the heating element.
Set the temperature of the kiln to 400 degrees Fahrenheit. Preheat the kiln for at least 30 minutes.
Open the door insert ceramic stilts into the kiln. Ceramic stilts keep the bisque from touching the bottom of the kiln so the glaze doesn’t stick.
Set the glazed ceramic bisque on the ceramic stilts. Position the bisque so it is level to the bottom of the kiln.
Close the kiln door and open the vent holes. If the kiln doesn’t have vent holes, crack the door open 1/2-inch.
Bake the bisque for one hour.
Close the vent holes. If the kiln doesn’t have vent holes, close the door.
Bake the bisque until the glaze is dry. Depending on the size of the bisque, this may take between 30 and 60 minutes.
Open the door. Slide an enamel fork underneath the base plate of the kiln.
Lift the enamel fork and balance the base plate on it. Pull the enamel fork out of the kiln and set the base plate on a heat resistant surface.
