Le Creuset · Pizza Stones & Baking Surfaces
Le Creuset Round Pizza Stone
Pizza stone is ceramic; lower PFAS concern for baking use.
Le Creuset pizza stones are fired stoneware ceramic, an inherently PFAS-free material with no nonstick coating or surface treatment. No PFAS risk expected from normal baking use.

What’s concerning
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Thermal cracking and structural failure
Stoneware is prone to thermal shock if moved rapidly between temperatures or exposed to direct heat sources. Cracking is a structural failure mode, not a chemical hazard, but compromised surfaces can harbor bacteria or ceramic fragments in food.
Water absorption and mold growth
Unglazed stoneware can absorb moisture if not properly dried after washing, creating conditions for mold or mildew in storage. This is a maintenance and hygiene risk rather than a chemical exposure.
What’s reassuring
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Lead
No recalls or testing documentation on record for Le Creuset or Sur La Table stoneware. FDA permits lead migration testing but does not require pre-market disclosure for cookware; reputable ceramic cookware manufacturers typically test negative, though public proof is not always published.
Source: ATSDR ↗Aluminum leaching from base or support
This product is pure ceramic with no metal components listed; aluminum leaching is not a concern unless the stone is used with aluminum accessories or on aluminum racks.
Coating degradation (glaze)
Ceramic glaze, once fired, does not degrade under normal baking use and does not flake or peel like non-stick coatings. The risk of glaze release into food is negligible for intact stoneware.
The full breakdown
What it's made of and why it matters
This is a stoneware ceramic pizza stone, a fired clay product without non-stick coatings or metal substrates. Stoneware ceramics do not rely on synthetic polymers or fluorinated compounds for their baking function, eliminating Teflon-type coating fume risk entirely. The material is inert once fired; food contact poses minimal chemical leaching risk under normal baking temperatures (typically 400-500°F, well below ceramic degradation thresholds).
The brand's record and disclosure
Sur La Table (which sells Le Creuset products as a retailer) does not prominently disclose ceramic production standards or heavy-metal testing data on product pages. Le Creuset, the manufacturer, has no documented recalls or safety controversies related to their stoneware cookware. Neither brand publishes independent third-party certification (e.g., lead/cadmium testing reports) as standard practice, which is typical for premium ceramic cookware but limits transparency.
How it compares in its category
Ceramic pizza stones avoid risks inherent to metal alternatives: aluminum leaching, non-stick coating degradation, and lead in enamel glazes. They are safer than unglazed ceramic from unknown manufacturers, where lead/cadmium in surface finishes can pose a hazard. The main trade-off is durability and thermal shock sensitivity (thermal cracking if exposed to rapid temperature swings), which is a use limitation rather than a chemical safety issue.
If you buy it
Preheat slowly to allow even heat absorption and avoid thermal shock cracking. Do not use on stovetops or under direct flame; this is a baking-only tool. Hand wash gently; stoneware can absorb water and crack in dishwashers. Replace if deep cracks or chips develop, as they can harbor bacteria or cause sudden failure, though intact ceramic poses no chemical risk.
