Our pizza stones are made from a premium, proprietary blend of cordierite that will withstand temperatures above 1400°F. We crafted your stone in a refracting oven at temperatures over 1800°F. It’s designed to withstand the intense heat of a pizza grill, a professional pizza oven, a gas grill, a pellet grill, or even a Big Green Egg or a Kamado Grill—we’ve even used ours over a roaring campfire.
