Should I Preheat Pizza Stone?
Preheating a pizza stone is usually worth it for thin- to medium-crust pizza in a hot home oven, because it creates a crisp, evenly browned bottom and helps the oven recover between pies. It is less suitable for cracked, low-rated, or damaged stones, or for thick, heavily topped pizzas that need a long, gentle bake. Weigh your pizza style, oven temperature, available time, and the condition of the stone before deciding.
