The tiles are unglazed, 8 inches square and about 3/4" thick. I bought them to get a crispier and darker bottom to the crust than the pizza stone I used.
The best I got was a pale tan color. I like when the pizza is actually burnt in some places.
I heated up my oven, wolf electric convection, to 550 degrees, the highest temp and cooked several pizzas over 1 1/2 hours so even if the first pizza was cooked on a stone not fully heated, i would have thought the one of the following ones would have.
before I through them out, can anyone offer suggestions?
