Designed to work perfectly with a Breville Countertop Convection Oven, this pizza stone's porous surface draws moisture away from the dough for crispier crusts. Its special construction also distributes heat evenly across the entire pizza to maintain an even baking temperature. To use, simply preheat the stone in your Breville Countertop Oven at 450deg. F for 15 minutes. The stone can also be used with a traditional full-size oven. Model #BOV800PS13 13" diam. Made in China.
