If you bake bread or make homemade pizza, you know the value of a ceramic baking stone. A porous baking stone allows moisture to be released from the crust that's in contact with the stone, helping create light, flaky crusts. The stone also helps maintain a consistent oven temperature, giving better results. Experienced bakers swear by these stones.

That said, all baking stones are not alike. These are genuine Old Stone Oven baking stones, thicker, heavier and stronger than other brands. They're made of ceramic material similar to that which lines kilns, guarding against thermal shock that can crack or shatter lesser stones.
