How We Chose the Best Thick Pizza Stone
To build this guide to the best thick pizza stone, we compared pizza and baking stones and steels sold on Amazon US by material (cordierite, ceramic, cast iron or carbon steel), size, thickness, weight, heat rating, shape and included accessories. We then read patterns in verified-buyer reviews for cracking, heat recovery, crust results and cleanup, and flagged listings with few ratings or ratings shared across sizes.
Preheat stones slowly with the oven, never wash them with soap, and let them cool fully before handling. Follow USDA Food Safety and Inspection Service cleanliness guidance for handling dough and toppings. Our method is explained on the How We Test page; this is a research-based guide, not a lab test.
