Thermarite is our copyrighted name for the proprietary formulation we use to make our pizza stones.
Our formulation is a premium-quality mineral blend developed over years of research and development. It is fired at extreme temperatures to give Thermarite exceptional performance as well as extreme durability.
We’ve actually tested the stone by heating it in an open campfire and then plunging it into a snowbank—and it still did not crack or break. (p.s. Don’t try this at home!)
