Bake perfect pizzas and flatbreads while camping with this 12mm/0.47'' thick pizza stone. This pizza stone can be used on most gas- and charcoal barbecues (and even your electric oven at home). The stone is made from durable, heat-resistant cordierite, which draws the moisture out of the dough while the aluminum heat spreader distributes the heat evenly over the stone, making for great pizzas and flatbreads.
