Our kiln shelves are made from a refractory mix that is high in alumina and are rated for use up to cone 11 in oxidation or reduction atmospheres.

Due to the fragility of the shelves, only sizes 15" and under can ship through UPS/Mail - and to do so there is an additional $25.00 packaging fee. All larger sizes must be shipped through a freight company on a skid to ensure they arrive safely. Due to this it can be costly to ship, and is ideal to ship with larger clay orders. Contact our showroom if you have any questions.
