Cordierite

Core Lite

Hollow Core

Silicon Carbide

Here at The Ceramic Shop, we have a wide variety of kiln shelves in stock and ready to ship. Pressed Cordierite (high-refractory) shelves are the standard shelf that comes with most American-made kilns. These are also 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 Hollow Core Shelves and Corelite these shelves are extruded and have hollow centers. Although they are slightly more expensive than the standard Cordierite shelves, they are just as strong, which will save your back when loading. We also carry silicon carbide shelves. These shelves are ideal for high temperature firing in gas kilns, and especially for use in atmospheric firings. We do not recommend them for use in your electric kiln, because these shelves can conduct electricity.
