Over 25 years ago the Old Stone Oven Company first introduced the original baking stone for home use, designed by international pizza expert, Pasquale Bruno. It is still the best on the market. It has a porosity and heat retention that is unmatched for giving a delicate crispy, restaurant-quality crust to any pizza, focaccia or bread in a standard home oven. Stone is a pure ceramic product made of clays fired at over 2000-degrees Fahrenheit. 7-inch by 10-inch fits all Toaster Ovens or can also be used in the microwave by preheating for 5 minutes. Perfect for recrisping last night"s pizza, baking frozen pizza slices or made-from-scratch mini-pizzas. Complete instructions and recipes are included. Made in the USA.
