How are enamels for glass fired: (courtesy of Thompson Enamels)

After applying the enamel to a glass piece, the work is placed onto a kiln shelf or on kiln paper or ceramic or coated metal mold for slumping. It is placed into the kiln at room temperature. A firing schedule appropriate for the size and thickness of the glass should be consulted. The temperature needs to climb at a specific rate to above 700 degrees F. After reaching that temperature it can go up a little faster until it reaches the maturation temperature. For both window glass and stained glass we suggest 1430 degrees F. (although depending on the desired result the temperature could range between 1300 to 1500 degrees F.) The temperature is then allowed to cool down to 900 to 1000 degrees F. It is held there for at least 1/2 hour to allow stresses in the glass to be relieved. The power is turned off and the temperature is allowed to go back to room temperature before the ware is removed.
