Hanger stone

Profile picture for user easyquilts
I have been wanting a baking stone for a while, so when I saw a Haeger Pizza Stone at Cosco, for a really good price, I bought it. I want to bake both pizzas and bread on it. The directions say to preheat the oven... Not the stoneware. I had wanted to be able to preheat the stone, for breads... Does this mean I cannot? Also, it says not to exceed 450 degrees. Should I keep the stone? Sandy
