Unicook 13" Cordierite Pizza Stone for Oven & Grill — 13x13in Thin 0.4" Baking Stone with Dough Scraper for Crispy Crusts

If you want a reliable, high-heat surface for pizza, bread, cookies and more, this 13 x 13 x 0.4 inch baking stone from Unicook is built for the job. Made from dense cordierite, the stone tolerates extreme temperatures and resists thermal shock so you can move between cold and hot environments without cracking. It ships with a plastic dough scraper for shaping and portioning, and fits many compact outdoor pizza ovens as well as standard kitchen ovens and grills.

How does this stone improve pizza and bread baking?

The Unicook cordierite stone absorbs and conducts heat quickly into dough, encouraging faster oven spring and a crisp bottom crust while keeping the interior tender. Its porous surface wicks moisture away from the dough so steam doesn’t soften the crust during baking. That combination yields a balance of crunch and chew you expect from wood-fired ovens.

• Porous cordierite draws moisture away for crisp crusts
• Even heat distribution reduces hot spots and burning
• Thin 0.4" profile heats rapidly while retaining steady heat
• Works with fresh, par-baked, and frozen dough

Will it fit my oven or outdoor pizza oven?

This stone measures 13" by 13" and suits ovens, grills, and compact pizza ovens with similar dimensions — such as Ooni Fyra 12, Karu 12/12G, and Koda 12. Check your cooking chamber or grill grate dimensions to confirm clearance, and allow space for air circulation on all sides for best performance.

• Nominal size: 13" x 13" x 0.4" (33 x 33 x 1 cm)
• Compatible with many 12" class outdoor pizza ovens
• Fits standard home ovens and most gas/electric grills with adequate surface area
• Measure interior dimensions before purchasing to ensure fit

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

Caring for the Unicook stone is simple: let it cool completely, then hand-wash with warm water and a plastic or nylon brush. Do not use soap, detergent, or oil-based seasoning — cordierite absorbs and can retain residues. Avoid sudden temperature changes to reduce risk of cracking despite the stone’s thermal shock resistance.

• Cool completely before cleaning to prevent thermal shock
• Hand-wash with warm water; avoid soap or detergent
• Do not oil or season; no greasy coatings needed
• Use the included plastic dough scraper on cool surfaces only

What temperatures and cooking tasks is this stone designed for?

Unicook cordierite withstands very high temperatures (up to 1,450°F/787°C) making it suitable for fast, high-heat pizza bakes and general baking tasks. While home ovens rarely reach those extremes, the stone’s high tolerance adds durability and consistent performance for pizzas, artisan breads, flatbreads, cookies, and reheating leftovers.

• Rated up to 1,450°F (787°C) for durability
• Ideal for pizzas, bread, pastries, pies, and cookies
• Great for both fresh and frozen convenience foods
• Compatible with ovens, grills, and compatible outdoor pizza ovens

Who is this for: home bakers and outdoor pizza enthusiasts who want a durable, quick-heating baking surface that produces crisp, evenly-cooked crusts without complicated maintenance. It’s a practical upgrade for anyone using compact pizza ovens, grills or standard kitchen ovens who wants better texture and consistent results for pizzas, artisan breads, and baked goods.
