KitchenStar 16-Inch Pizza Stone for Oven and BBQ Grill with Handles, Round, 5/8" Thick - Natural Cordierite, 1800F Resistant, with Stainless Steel Rack & Scraper Tool
KitchenStar's 16-Inch round 5/8" thick cordierite pizza stone, 1800F resistant, with stainless steel rack and scraper tool.
Cordierite is a mineral-based ceramic prized for exceptional thermal shock resistance, meaning a cordierite pizza stone can go from cold to a 900 degree grill without cracking the way ordinary clay and ceramic stones often do. That durability makes cordierite the default recommendation for home pizza makers, especially anyone using a stone inside an outdoor pizza oven or on a grill where temperature swings are violent. Cordierite also absorbs surface moisture from dough, helping crusts crisp evenly. When picking one, compare thickness, with half-inch to five-eighths offering the best balance of heat storage and preheat time, verify the maximum temperature rating, match dimensions to your oven or grill, and check edge design for easier peel access.
