How to use a pizza stone
The pizza stone has to be preheated to a certain temperature to work and that often means leaving the oven on for quite a while before you begin to cook. Always place your stone in a cold oven and then turn the oven on. The purpose of this is to allow the stone to absorb the heat evenly. Once the stone has reached the required temperature then it is far too hot to handle with a conventional oven glove. Remember that you are working with a fire brick! If you place your cold pizza stone (no matter how expensive it was) into a hot oven it will very probably not withstand the thermal shock and it will shatter.
