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 nonstick and easy to clean. The stones heat evenly for crisp-crust pizzas and perfectly cooked baked goods.
