If you want to bake the Napoleon cracker crust pizzas.. I suggest using a baking steel (carbon plate 1/4-1/3").
At 500º, it mimics 900º on a standard baking stone, creating the same leoparding on the crust.
My baking stone works beautifully for bread and dough with yeast at about 550-600º.
The density of the stone determines how fast it cooks.. Heat transfer.
