38×30CM Heat-Resistant Natural Cordierite Rectangle Pizza Stone
Our 38×30CM natural cordierite pizza stone blends food safety with industrial durability: made from high-purity cordierite (with SiO₂ 48%, MgO 10%, Al₂O₃ 40%), it resists 800-1350℃ high temperatures, has ultra-low thermal expansion (similar to diamond), and contains no harmful ingredients. Suitable for both household/commercial pizza ovens (gas, charcoal) and ceramic kiln carts, it ensures even heating for crispy pizza crusts while enduring frequent thermal cycles in industrial kilns. Backed by CE certification, SGS test reports, and 100,000 pieces monthly capacity, we offer customization and 5-year quality warranty to meet retail and industrial demands.
Description
1. Product Overview
This dual-purpose cordierite product is manufactured via natural mineral purification, precision cutting (38×30CM standard size), high-temperature sintering (1400℃+), and surface polishing. Its unique cordierite crystal structure delivers two core advantages: food safety (no harmful substances released at high temperatures, compliant with global food contact standards) and industrial-grade durability (low thermal expansion coefficient, resisting cracking from rapid temperature changes). For home use, it absorbs excess moisture from pizza bottoms to create crispy crusts; for ceramic kilns, it serves as a stable kiln cart plate, withstanding 1280-1350℃ long-term use. It solves the pain points of ordinary pizza stones (easy cracking) and ceramic kiln plates (uneven heating), with a service life 3× longer than ceramic alternatives.
2. Key Features
Extreme Heat Resistance: Safe for 800-1350℃ use (max refractory temperature 1580℃), 适配 pizza oven preheating and ceramic kiln firing without deformation.
Ultra-Low Thermal Expansion: Thermal expansion coefficient close to diamond, enduring 20+ rapid cold-hot cycles (e.g., 1300℃ to room temperature) without cracking-ideal for frequent oven/kiln startup/shutdown.
Food-Safe & Eco-Friendly: SGS-certified, no heavy metals (CrO ≤0.01%, SiC ≤0.01%) or harmful additives; high-temperature sintering ensures no odor or contamination to food.
Dual-Purpose Design: 38×30CM rectangle size fits most household/commercial ovens; 1.85-2.0g/cm³ density balances heat retention and lightweight handling (single piece net weight ~1.5kg).
Easy to Clean & Durable: Smooth polished surface prevents food sticking; waterproof coating simplifies cleaning (wipe with a damp cloth after cooling); 5-year quality warranty for retail, 1-year warranty for industrial use.
