Unicook Cordierite Pizza Stone 16x16 Inch Square — 0.6" Thick, Heavy-Duty Heat Retention for Crisp Crusts

This square cordierite stone measures 16" x 16" with a 0.6" (15 mm) thickness and weighs about 9.6 lbs, engineered to absorb and hold high heat for consistent baking. Built to resist thermal shock up to 1,450°F (787°C), it works on gas and charcoal grills, conventional ovens, and compatible outdoor pizza ovens like the Ooni Koda 16 — just allow a full inch of clearance on all sides for proper airflow. The stone’s porous surface wicks away moisture so crusts brown evenly and become crisp without sogginess.

How does this stone improve pizza and bread crust?

The cordierite material stores and radiates heat evenly, removing cold spots that cause underbaked centers. Its porous structure soaks up excess dough moisture for a crunchier bottom and edges, while the heavy mass maintains steady temperature when the oven door opens.

• High thermal mass preserves heat for crisping crusts quickly.
• Porous surface absorbs moisture, reducing sogginess.
• Even heat distribution prevents hot and cold spots.
• Reversible smooth faces let you rotate use across surfaces.

Will this stone fit my oven or grill and how should I install it?

Measure your oven or grill interior and confirm at least 1 inch of clearance on all sides before placing the 16" square stone inside. For safe, even results, place the stone in a cold oven or grill and bring the heat up slowly to avoid thermal shock; preheating together prevents cracking and improves cooking performance.

• Check interior dimensions and allow 1" clearance on each side.
• Start heating from a cold oven/grill to preheat the stone gradually.
• Use oven mitts or a grilling spatula to handle the hot stone safely.
• Compatible with Ooni Koda 16 and many conventional/charcoal grills.

How do I use and care for the pizza stone to keep it working well?

Use a pizza peel to slide pizzas onto the preheated stone and a multi-purpose plastic scraper to remove stuck-on residues once the stone has cooled. Clean with warm water and gentle scraping only — avoid soaps, oils, or seasoning; discoloration over time is normal and does not affect performance.

• Remove excess food with provided scraper after cooling.
• Hand wash with warm water; do not use soap or oil-seasoning.
• Allow full cooling before cleaning or storing to avoid cracking.
• Minor discoloration or dark spots are typical and harmless.

What else can I bake on this stone besides pizza?

The stone is versatile enough for bread, calzones, cookies, pies, and flatbreads. Its heat retention and moisture-wicking properties improve crusts and bottoms for a wide variety of baked goods, turning ordinary home baking into bakery-style results.

• Fresh and frozen pizzas bake more evenly with crisp bottoms.
• Artisan breads develop better oven spring and crunchy crusts.
• Cookies and small pastries achieve more uniform browning.
• Calzones, tarts, and flatbreads benefit from the same heat transfer.

Who is this for: Home cooks and pizza enthusiasts who want a professional-style baking surface that fits larger ovens and many grills. It's ideal for families who bake regularly, hobby bakers looking to improve crust texture, and outdoor cooks who need a durable, high-temperature stone that resists thermal shock. If you need a reliable, easy-to-maintain stone for pizzas, breads, and more, the Unicook 16 x 16 cordierite stone is a practical upgrade for kitchen and grill use.
