Made from the same reliable formula as our regular high alumina shelves, these shelves are also rated for cone 10 but are 35% lighter.

The extrusion process provides a kiln shelf with a core I-beam construction for strength and rigidity, but at a much lighter weight than regular kiln shelves. 

The Oval Kiln Shelf is 39” long X 22” wide X 1”:
This shelf will fit into any of the Cone Art oval pottery or glass kilns. It is perfect for those large glass projects or ceramic sculptures which would be affected by a seam between two shelves.
