Our Superstone® Baking Stone replicates the effects of a professional pizzeria oven. The stone absorbs moisture, creating a crispy pizza crust! The rectangular shape is great for a Sicilian-style pizza. Also great for cookies, pretzels and anything with a dough! To clean, simply scrub under hot water -- do not use soap. Superstone® measures 13" wide x 15" long. With rack, it measures 17" long. Includes recipes.
