Outspark Cordierite Pizza Stone for Ooni Koda 16 — 16.7×20.5 in, 0.5" Thick for Faster, Crispy Crusts

Outspark's cordierite pizza stone is a heavy-duty baking slab sized to fit the Ooni Koda 16 and similar ovens, delivering a fast, even-heated surface for crisp crusts.

If you want restaurant-style texture from your home pizza oven or grill, this slab is engineered to store and radiate high heat while drawing moisture from dough for a crisper finish. Made from dense cordierite, the stone resists thermal shock and can be used inside countertop ovens, outdoor pizza ovens such as the Ooni Koda 16, and on grills. The single-piece stone measures 16.7 by 20.5 inches with a 0.5-inch thickness—large enough for multiple small pizzas or one sizable pie, and thin enough to reach baking temperature quickly.

How does this stone improve pizza crust texture?

The stone soaks up surface moisture and returns focused heat to the dough, which helps form a golden, blistered crust rather than a soggy base. Its cordierite composition balances heat retention and responsiveness so toppings cook without overbaking the rim.

• Absorbs water vapor from dough for a drier, crispier bottom.
• Conducts and radiates heat evenly to avoid hot spots.
• Half-inch thickness balances heat-up speed and thermal mass.
• Large surface fits most 16–17" oven footprints for even baking.

Will this work in my Ooni Koda 16 or other ovens and grills?

Yes—the Outspark stone is sized for the Ooni Koda 16 but also fits similarly sized countertop ovens or can sit on a grill grate. It’s oven-safe and built to tolerate the high temperatures used for fast pizza baking.

• Dimensions: 16.7" × 20.5" × 0.5" to match most 16" class ovens.
• Cordierite rated for very high temperatures, suitable for outdoor ovens.
• Works on gas, charcoal, and electric grill setups when used carefully.
• Also compatible with home ovens for breads, cookies, and pastries.

How do I care for and clean the pizza stone?

Maintenance is straightforward: let the stone cool fully, remove loose crumbs or baked-on bits with a scraper, and rinse with warm water. Avoid soaps and detergents which can be absorbed into the porous surface; dry completely before storing.

• Allow full cooling to avoid thermal shock and cracking.
• Scrape residue with a plastic or wood spatula; use minimal water.
• Never use dishwasher soap—cordierite is porous and can retain scents.
• Store flat and dry to extend the stone’s lifespan.

What else can I bake on this stone besides pizza?

The stone’s heat properties make it ideal for bread loaves, flatbreads, cookies, and reheating items to restore crispness. Sprinkle a little flour or semolina to prevent sticking and to create extra crunch under crusty bakes.

• Artisan breads: better oven spring and crust development.
• Flatbreads and focaccia benefit from direct radiant heat.
• Cookies and pastries brown more evenly than on metal sheets.
• Reheating leftovers keeps crusts crisp instead of soggy.

Who is this for: home cooks and outdoor oven enthusiasts who want a professional-style baking surface for their Ooni Koda 16 or similar ovens. It’s suited to anyone who bakes frequently—especially pizza and bread lovers—looking for a durable, high-heat stone that improves crust texture and holds up to heavy use. The Outspark stone is also a practical gift for people upgrading their pizza kit or outfitting a backyard pizza setup.
