Unicook 12" x 12" Cordierite Pizza Stone for Oven & Grill — 0.57" Thick Square Baking Surface for Crispy Crusts

Unicook's 12"x12" cordierite pizza stone is a durable square baking surface that soaks up moisture and delivers evenly browned, crisp crusts in ovens and grills.

This 12"x12" Unicook pizza stone is engineered from high-quality cordierite to withstand extreme temperatures and to spread heat uniformly across your pie, loaf, or pastry. At 0.57" (14.5 mm) thick it fits many 12" pizza ovens such as Ninja MO201/OO101, Cuisinart CPZ-120, and similar models — just be sure to leave at least 1" of clearance around the stone for airflow and safe use. The stone’s porous surface draws out excess moisture from dough, helping pizza and bread develop a crisp bottom without burning or sogginess.

How does this stone create a crisper pizza crust?

The cordierite material has a porous structure that absorbs surface moisture while it conducts and stores heat. That combination yields a drier dough surface and steady radiant heat, which encourages a quick oven spring and even browning.

• Porous cordierite wicks away moisture for a firmer crust texture.
• High thermal mass holds heat to brown and crisp bottoms consistently.
• Preheating the stone in a cold oven/grill ensures uniform heat penetration.

Will this stone work in my pizza oven, oven, or grill?

The Unicook stone is sized for 12" pizza ovens and many countertop pizza ovens but will also function in conventional ovens and grills. Measure your interior space and allow a 1" clearance around all sides to ensure proper airflow and safe heating.

• Measures 12" x 12" and 0.57" (14.5 mm) thick — compatible with many 12" ovens.
• Suitable for gas, electric ovens and grills; avoid direct flame contact.
• Not recommended if your oven interior leaves under 1" clearance on any side.

How do I care for and maintain the cordierite baking stone?

Caring for cordierite is straightforward: allow the stone to cool before cleaning, use the included plastic scraper to remove debris, and rinse with warm water. Do not season with oil or detergents; discoloration over time is normal and doesn’t affect performance.

• Clean cooled stone with scraper and warm water only — no soap or oil seasoning.
• Frequent use may cause natural discoloration; this is cosmetic only.
• Avoid thermal shock by preheating the stone inside a cold oven/grill rather than placing it into a hot appliance.

What else can I bake besides pizza?

The Unicook stone is versatile enough for breads, calzones, cookies, pies, and reheating frozen items to crispness. Its reversible smooth surface lets you use both sides, and the package includes a multipurpose plastic scraper for dough cutting and residue removal.

• Ideal for artisan loaves, flatbreads, and calzones that benefit from bottom crisping.
• Great for reheating frozen pizza to recover texture lost in microwaves or metal pans.
• Reversible surface increases usable life and allows rotation to manage wear patterns.

Who is this for: Home cooks and pizza enthusiasts who want restaurant-style crispness without complicated equipment, owners of countertop 12" pizza ovens seeking a reliable replacement stone, and bakers who value a durable, high-temperature surface for breads and pastries. If you use ovens or grills regularly and want a simple way to improve crust texture and evenness, the Unicook 12"x12" cordierite stone is a practical tool for everyday baking.
