High Alumina kiln shelves are a good alternative to expensive silicon carbide while being roughly half the price.  These shelves have up to 12% more alumina than standard Mullite/Cordierite shelves that most commonly used. This gives these shelves a higher firing range, up to Cone 11 or 12. They are quite durable and not subject to thermal shock problems that afflict shelves that are mainly composed of alumina. We have had great success with these shelves in gas and electric kilns. You can save your back by buying thinner shelves that are stronger than their 1″ counterparts in the less durable compositions.

This is such a great place if you are a starving artist who is a clay addict! The employees are so helpful and Marcie and Quinn are great! I love how they have their own line of glazes and clays to choose from. I favor their Whitestone stoneware. It is a finely compounded stoneware with a porcelain appearance and feel, great for throwing on the potters wheel... Y'all should visit this store if you love exceptional quality materials and customer service. Five stars all day!
