Is Weber Crafted Pizza Stone 7671 non-toxic? What it is made of
The Pizzacraft 7671 is cordierite ceramic, a mineral composite engineered to withstand thermal shock and high oven temperatures (typically rated to 1200F or higher). Cordierite is inert when fired and does not leach contaminants under normal use. Unlike glazed or enameled cookware, this uncoated stone has minimal surface chemistry to degrade or release unwanted substances into food.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Thermal shock and structural failure
Cordierite is durable but not indestructible. Rapid temperature changes or contact with cold liquid can cause cracking; impact damage during handling or storage is also a risk. A cracked stone may shed ceramic particles into food or collapse unexpectedly.
Mineral dust inhalation during prep and cleaning
New or aged cordierite stones may shed fine ceramic dust, especially if dry-wiped or lightly sanded before use. While cordierite itself is not a known respiratory carcinogen, prolonged inhalation of any fine dust is best avoided; brief exposure during handling is minimal risk.
Contamination from porous surface
Unglazed cordierite is porous and can absorb oils, food residues, and odors over time. If the stone is not cleaned promptly or if spills soak into the surface, mold or bacteria may grow in warm, damp conditions. This is a hygiene concern rather than a chemical hazard.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
The Pizzacraft stone is unglazed and uncoated, so traditional glaze hazards do not apply. No surface treatment is known to introduce lead or cadmium contamination in this product.
Source, ATSDR ↗PFAS
Uncoated ceramic pizza stones are not known to contain PFAS, which are typically found in non-stick coatings or water-repellent treatments. Cordierite as a raw mineral does not inherently carry PFAS risk.

The brand's record and disclosure
Pizzacraft does not publish extensive safety documentation or certifications for this product line. No recalls or safety complaints are on record for the Weber Crafted Pizza Stone 7671 specifically. The brand takes a silent stance on PFAS and other chemical safety metrics, which is typical for this product category but limits transparency. No third-party certifications (e.g., FDA, NSF) are marketed for this stone.
How it compares in its category
Uncoated cordierite stones are the industry standard for pizza ovens and home use; they are chemically simpler than cast iron or metal-core alternatives that may have surface coatings or treatments. This product sits in the middle tier of residential pizza stone offerings and does not employ proprietary coatings or additives known to raise safety concerns. Performance and durability are comparable to competitor models from Emile Henry or traditional Italian cordierite stones.
If you buy it
Season the stone lightly with oil before first use to reduce dust and improve heat retention. Preheat for at least 30 minutes before cooking; do not subject a cold stone to direct high heat (thermal shock can cause cracking). Hand wash only; dishwasher use or prolonged soaking can degrade the stone over time. Replace if visible cracks develop, as they may propagate during heating and risk breakage in the oven.
