Pizza stones are great for those who want to make their own pizza but don't have a pizza oven, as the stone removes moisture from the dough and provides a crispy crust. They can make a pizza feel much higher quality than an oven on its own, but you may want to think twice before using it with a frozen pizza.

Most pizza stones are made from ceramic or similar material, making them prone to thermal shock — a rapid temperature change that strains the product and causes cracking. Your stone should ideally be pre-heated with the oven to avoid this shock, so placing a frozen pizza directly onto the hot pizza stone can break or destroy it due to the sudden temperature change.

It's best to bake a frozen pizza directly on the oven rack to allow the heat to circulate underneath it and crisp the crust without the risk of thermal shock. You can also cook a frozen pizza on a baking sheet, though you might not get the same crunchy, crispy results.
