Unicook Cordierite Pizza Stone 15 x 12 in Rectangular — 0.6" Thick, Reversible Baking Surface for Oven & Grill

The Unicook 15 x 12 inch rectangular pizza stone is a durable cordierite baking surface designed to create crisp, evenly cooked pizzas and baked goods in home ovens and grills.

If you want restaurant-style crust without buying a pizza oven, this mid-size rectangular stone brings professional heat retention and moisture absorption to your kitchen. Made from high-density cordierite, it spreads heat evenly and tolerates very high temperatures so you can bake pizzas, bread, rolls, and cookies with fewer hot spots and a better crust texture. The stone’s reversible faces and included plastic dough cutter give straightforward, low-maintenance performance.

How does this stone improve pizza crust and overall bake quality?

The porous cordierite surface pulls moisture away from dough during baking, promoting a golden, crisp bottom while the stone’s mass stabilizes oven temperature for consistent browning. Preheating the stone helps transfer heat quickly to the dough, reducing soggy centers and uneven edges.

• Porous surface absorbs excess moisture for crisp bottoms
• Thick 0.6-inch profile stores and distributes heat evenly
• Cordierite construction resists thermal shock and warping
• Reversible smooth faces allow even wear over time

Will this stone fit my oven or grill and what size pizzas will it handle?

The Unicook rectangular stone measures 15" x 12" and weighs about 6.8 lbs, making it suitable for many standard home ovens and medium grills. For best performance leave 1–2 inches of clearance on all sides to allow airflow and safe handling; it’s recommended for personal pizzas up to 11" in diameter.

• External dimensions: 15" L x 12" W x 0.6" thick
• Ideal pizza size: up to 11 inches across
• Clearance tip: maintain 1–2 inches on all sides inside oven/grill
• For larger or round grills, consider Unicook’s alternate models

How do I use and care for the cordierite pizza stone safely?

Always preheat the stone in a cold oven to the baking temperature to avoid thermal stress; allow the stone to cool fully before cleaning. Clean by scraping or brushing off residue and rinsing with warm water—avoid soaps or detergents which can be absorbed by the porous material.

• Preheat stone inside the oven to recommended baking temperature
• Cool completely before attempting to clean or move it
• Use the included plastic dough cutter/scraper for crumbs and stuck bits
• No detergent—hand wash with warm water and a brush if needed

What else comes with the stone and what materials are used?

The package includes a multi-purpose plastic dough cutter that doubles as a cleaning scraper for removing baked-on residue once the stone is cool. The stone itself is made from heat-resistant cordierite rated to withstand high temperatures for long-term baking performance.

• Included tool: plastic dough cutter/cleaning scraper
• Material: high-quality cordierite, heat-resistant to very high temperatures
• Surface: reversible smooth finish for two-sided use
• Weight: approximately 6.8 lbs for stable heat retention
