Eva Solo’s baking stone can be used to bake pizza, bread, cookies and other baked goods both on gas and charcoal grills and in the oven. Its porous surface draws moisture out of the dough and gives pizzas and breads a delicious, crunchy crust. The stone is made of unglazed ceramic and has a diameter of 13.98 x 0 in (35,5 x cm. cm). Clean with hot water after each use.
