# Best Cordierite Pizza Stones: Crack-Resistant Baking Source: https://pizzaovencraft.com/best/best-cordierite-pizza-stones Updated: 2026-10-20 Publisher: Pizza Oven Craft. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://pizzaovencraft.com/how-we-research#our-score 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. ## Picks ### 1.
