Large Pizza Stone 20in x 13.5in Rectangular - Thick Cordierite Stone

In this review of the Large Pizza Stone 20in x 13.5in, the bottom line is simple: this is a workhorse baking stone for home cooks who want restaurant-style, crispy crusts without fuss. Built from 100% all-natural cordierite and sintered at very high temperatures, the stone delivers steady heat, strong thermal shock resistance and no off smells when heated. It suits people who bake family-size pizzas, breads or calzones and who value a heavy, durable stone that holds heat for even, consistent baking.

Key Features

• 100% Cordierite: Sintered in a 2100F kiln, the stone resists thermal shock and stays odor-free when heating for reliable performance.
• Generous size: The 20in x 13.5in rectangular surface fits family-size pizzas or two medium pizzas, expanding what can be baked at once.
• Thick, heavy build: At about 0.67in thick and roughly 13.4 lb, the stone holds heat longer for better crust browning and consistent oven temperature.
• Superior heat retention: Rated heat resistant up to 1450F, the material helps maintain a stable baking temperature even in grills or smokers.
• Moisture-absorbing surface: Fine, deep pores draw excess moisture away from dough to help produce a crisper crust similar to pizzeria results.
• Plastic scraper included: A multipurpose scraper helps remove residue and cut dough without risking the stone surface when cooled.

Who It's For

This stone is ideal for home bakers and grill owners who regularly cook larger pizzas or multiple items at once and want a durable, high-heat capable surface. Families who buy large take-and-bake pizzas or who like baking bread and calzones will appreciate the size and heat stability.

It is less suited to people who need ultra-light or very thin portable stones for travel, or those who prefer metal baking sheets for faster preheating and easier washing. Users should also be comfortable following stone care instructions rather than soaking or using soap.

Pros & Cons

Cons
