Homemade pizza night just got easier and more delicious with this pizza stone set. Four 7.5" square pans bake separately for personal-size pizzas, or the squares can combine into a 15" stone to make one large pie. Made of highly durable cordierite, the pizza stones have excellent thermal properties that allow them to cook pies in high-heat ovens or on the grill or open fire. The handsome matte finish in dark grey prevents oils and fat from penetrating, making the pans virtually non-stick and easy to clean. The stones heat evenly for crisp-crust pizzas and perfectly cooked baked goods.
