Product Care: Stones arrive ready for immediate use – there is no need to "season" a new stone with oil or soak the stone in water before each use. The natural properties of a stones will cause it to darken and spot with age; do not attempt to remove this discoloration. Do not ever use soap when cleaning the stone, just hot water and a non-abrasive scrubber. USE: For best results, pre-heat oven or grill to 500˚ F (260˚ C) and place stone in middle of oven on lowest rack or middle of grill for 30 minutes. When it is time to bake, dust stone with cornmeal before placing baked goods on top. If baking a prepared food item, bake as directed by manufacturer on packaging. For fresh pizza, a flat metal spatula or a pizza peel dusted with cornmeal works well for transferring food to the baking stone. Alternatively, using an oven mitt or glove, remove the hot stone from the oven , place food to be baked onto the stone and return both to the oven or grill. STONE WILL GET HOT! USE OVEN MITT OR GLOVE WHEN HANDLING.
