The Pizza Stone is made of all natural materials and is manufactured using Emile Henry's proprietary Flame® technology. The Pizza Stone can withstand high oven temperatures. The glaze is micro-crazed contributing to crispy well-baked crusts, just like a pizza oven. The Pizza Stone is not recommended for use on the stovetop. You can cut directly on the glazed pizza stone without damaging or scratching the surface. The Pizza Stone is easy to clean with soap and water and is dishwasher safe.
