Electric Burnout Furnaces

Grobet Fiber Burnout Furnaces
are insulated with space-age ceramic fiber for fast heating and cooling at low electrical cost. The firing chamber is 13" W x 13" D x 9" H (33 x 33 x 23 cm), large enough for volume jewelry making. These kilns fire to 1700° F (967°C), so you can also use them for low-fire ceramics, enameling on metal, china painting or glass fusing. A heavy steel case protects the firing chamber for long life and the chamber is supported by a double-layer steel bottom. The base lifts the furnace off the work surface so no stand is needed. You can watch the firing chamber during heating through a peephole in the door. The peephole and top vent-hole are sealed with: metal covers when not in use. The door remains tightly sealed, even at high temperature, with the spring-loaded latch. Heats to 1,000° F (538° C) in 30 minutes.

The digital control models use the DTC-800 controller, eliminating the need for a pyrometer. With this feature packed temperature controller, you can program up to eight ramps (raising or lowering the temperature at the rate you specify) and eight dwells (holding the temperature constant for the length of time you specify). The digital models use a type-K thermocouple, long proven for it's reliability. The controller will shut off automatically should the thermocouple fail and the controller stores up to six programs even if the power shuts off. The furnace has a one year warranty. The controller has a two year warranty. Can be shipped UPS. Shipping weight 108 lbs. (49 kg).
