Le Creuset 15" Round Pizza Stone
Lower PFAS concern, pizza stone material itself is uncoated ceramic, a traditional low-risk substrate.
Le Creuset pizza stones are unglazed stoneware/ceramic with no nonstick coating, eliminating the primary PFAS vector in cookware. No PFAS disclosures are needed or made by the brand because the material class carries minimal legacy risk.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This is unglazed stoneware, a fired clay product with no surface coating, glaze, or resin finish. Unglazed ceramic avoids the lead and cadmium leaching risks associated with glazed or enameled bakeware, since those hazards live in the glaze layer itself. The material is thermally stable and inert at typical pizza-oven temperatures (up to 500F for home use). No synthetic polymers, adhesives, or chemical treatments are involved in the substrate.
The brand's record and disclosure
Le Creuset is a legacy European cookware brand (owned by Groupe SEB) with established quality control practices, though they do not publicly detail PFAS testing or certification for individual products. No recalls or safety controversies specific to their pizza stones have been documented in public databases. The brand maintains general food-contact safety compliance but does not volunteer detailed material safety disclosures beyond regulatory minimums.
How it compares in its category
Unglazed ceramic pizza stones are among the safest substrates in the baking category because they eliminate glaze-based hazards entirely. This contrasts with some enameled cast iron or vitreous glass alternatives, which can release lead or cadmium if glazes are degraded or non-compliant. Unglazed stoneware is also simpler than composite materials or treated ceramics that may incorporate proprietary coatings.
If you buy it
Season lightly with oil before first use to prevent sticking and slow moisture absorption. Avoid thermal shock by preheating gradually and never running it under cold water immediately after use. Hand wash only; dishwasher can cause cracking over time. Replace if visible cracks develop, as they can propagate during high-heat use and may affect food contact integrity. Store in a dry location to minimize mold or bacterial growth in pores.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Lead/cadmium in glazes or ceramic coatings
This product is unglazed stoneware with no surface coating. Lead and cadmium hazards are confined to glaze layers, which this stone does not have.
Thermal degradation and glaze cracking
Unglazed ceramic is durable but can microcrack if exposed to thermal shock (rapid heating or cooling). Microcracks may trap food debris and bacteria; replacement is advisable if visible fractures appear.
Bacterial or mold colonization in porous substrate
Unglazed stoneware is porous and can harbor bacteria or mold in surface pits if stored damp or not dried thoroughly. Proper air-drying and storage in dry conditions mitigates this.
Heavy metals in clay raw material
Naturally occurring lead or cadmium in raw clay is extremely rare in modern commercial ceramic products from established brands. No contamination has been documented for Le Creuset bakeware.
Coating or adhesive off-gassing
Unglazed ceramic has no synthetic coatings, glazes, or adhesives that release volatile organic compounds or formaldehyde resins during use.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
