Here at The Ceramic Shop, we have a wide variety of kiln shelves in stock and ready to ship. Pressed Cordierite (alumina) shelves are the standard shelf that comes with most American-made kilns. These are also typically the most economical. They are relatively durable, they can be fired repeatedly to cone 10, and they can be used in either electric or gas kilns. There is now a lighter-weight version of these alumina shelves available - called Corelite shelves, these are the shelves shown above with the hollow centers. Although they are a bit more expensive than the standard Cordierite shelves, they are stronger and stay flat longer -- and are also much lighter than the standard shelves, which makes them a breeze to load if you are building stacks in a kiln by yourself. The black shelves pictured above are silicon carbide shelves. These shelves are ideal for high temperature firing and for gas kilns - because they conduct electricity, we do not recommend them for use in your electric kiln.

A Note for Glass Makers: Kiln shelfs may often have a rough surface, or are made with slight imperfections and pockmarks. While this is rarely an issue for ceramic artists, this may be troublesome for those who work with glass. While we cannot accept returns on shelves due to surface variations, we do suggest that glass artists use Thin Fire Shelf Paper which will help combat imperfections in the shelf surface.
