I just bought a rectangular baking stone, made by Old Stone Oven, to replace the one that finally cracked after 6 years of regular use. I've always seasoned my baking stones (have a round pizza one that is nearly black now) and many instructions online for care of stones recommend it, but the insert that came in the Old Stone Oven box says not to season it, not to ever spray oil on it, and not to bake high-fat foods on it. This seems contrary to everything I've ever done with a stone -- can anyone tell me if this stone is different somehow? Or are there just differing camps out there? Or has it been wrong all along to season them?
