Unicook 12" Cordierite Square Pizza Stone for Oven & Grill — Thermal Shock Resistant, Even Heat for Crisp Crusts

Unicook's 12-inch cordierite square pizza stone is a heavy-duty baking surface for oven or grill that delivers crunchier crusts by absorbing moisture and distributing heat evenly.

Whether you're recreating pizzeria-style pies, baking artisan loaves, or crisping cookies, this Unicook baking stone is built to handle direct oven and grill heat while resisting thermal shock. Made from durable cordierite that withstands rapid temperature changes, the 12" x 12" x 0.4" profile fits most home ovens and many grills. The package also includes a practical plastic dough scraper for dividing and handling dough.

How does this stone improve pizza and bread texture?

The Unicook cordierite stone has a porous structure that draws moisture away from dough during baking, yielding a crisper bottom and better oven spring. Its excellent heat retention and even heat transfer create a stable baking environment so crusts cook uniformly instead of developing hot spots.

• Porous surface wicks moisture to make a crisp crust
• High heat capacity maintains an even baking temperature
• Thermal shock resistance prevents cracking during quick temperature changes
• Suitable for pizzas, artisan breads, cookies, and reheating

Can I use this Unicook stone on both oven racks and outdoor grills?

Yes — the stone is rated for very high temperatures and is safe for use on both conventional oven racks and gas or charcoal grills when handled carefully. Place it on a preheated rack or grill grate and allow it to come to temperature gradually for the best results.

• Works in ovens and on most grills for versatile cooking
• Heat-resistant up to 1,450°F (787°C) for extreme cooking needs
• Use with a pizza peel or sturdy tongs when moving the hot stone
• Avoid sudden cooling to protect the stone’s integrity

What care and cleaning steps keep the stone performing well?

Unicook cordierite stones are low-maintenance: allow the stone to cool completely, then wipe or rinse with warm water and a soft brush. Do not use soap, detergents, or oil-based seasoning; those can clog the pores and affect baking performance.

• Cool fully before cleaning to prevent cracking
• Hand wash with warm water; scrub gently to remove residue
• Never use soap, detergent, or seasoning oil on the stone
• Store dry and flat to avoid warping

What extras come with the Unicook pizza stone and how does packaging protect it?

The stone ships in a reinforced box with foam and cardboard protection to prevent transit damage. Included with the 12-inch stone is a plastic dough scraper that functions as a cutter and handling aid for cold dough only.

• Secured in foam and cardboard for safe shipping
• Plastic dough scraper included for portioning and lifting dough
• Compact 12" square size fits many ovens and grills
• Neutral odor cordierite construction—no off-gassing
