Teesa Supreme+ Pizza Oven Stone The secret to achieving crispy and perfectly baked pizza dough in the Teesa Supreme+ oven is the use of a ceramic stone that distributes heat evenly, maintains a very high temperature, and absorbs moisture. New Stone, New Possibilities So if the stone in your Teesa pizza oven with a viewing window wears out, you can buy a new one that perfectly fits this model. Two metal handles with a burn-resistant coating ensure easy and safe stone replacement.
