Emile Henry · Pizza Stones & Ceramic Bakeware
Emile Henry Pizza Stone EH349514
Low PFAS risk, traditional stoneware pizza stone with no coatings or treatments.
Emile Henry pizza stones are made from unglazed or naturally glazed clay/stoneware without synthetic nonstick or waterproofing coatings. This material class does not inherently require or commonly contain PFAS. No brand PFAS claim exists, but the product category and material composition pose minimal concern.

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
The Emile Henry EH349514 is cast from natural clay and stoneware, fired at high temperature with no glazes, enamel coatings, or synthetic finishes applied to the cooking surface. This means there is no Teflon-type coating (nonstick resin), no epoxy liners, and no chemical treatments to degrade or release harmful compounds into food over time. High-fired stoneware is chemically stable under normal baking temperatures (up to 500°F typical use, often rated to 600°F).
The brand's record and disclosure
Emile Henry is a French heritage cookware brand with a long established history in ceramic bakeware and does not publicly disclose specific third-party safety certifications for individual products. The brand has no known recalls or public safety controversies related to lead, cadmium, or other heavy metals in its stoneware lines. Emile Henry maintains general quality standards but does not provide itemized material testing reports to consumers on this product.
How it compares in its category
Uncoated stoneware pizza stones are among the lowest-risk options in the bakeware category because they eliminate coating degradation, Teflon-type coating fume risk, and nonstick chemical leaching concerns entirely. Unlike glazed ceramic pieces, the EH349514 has no glaze layer where lead or cadmium contamination could hide, though raw stoneware does still carry a residual (very low) heavy metal leaching risk common to all clay products. Compared to metal or silicone alternatives, stoneware is functionally superior for pizza and bread baking and carries no polymer-related hazards.
If you buy it
Season the stone lightly with oil before first use and allow it to heat gradually to avoid thermal shock cracking. Do not use above 500°F for extended periods, and allow it to cool completely before washing; stoneware can crack if exposed to sudden temperature drops. Inspect periodically for deep cracks or chips that could harbor bacteria; replace if structural integrity is compromised. Hand wash only; dishwasher use will degrade the surface and accelerate wear.
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 and cadmium in raw clay
No recalls or public testing data exist for this specific Emile Henry product. Lead and cadmium leaching from unglazed stoneware is theoretically possible but occurs at trace levels well below regulatory thresholds in high-fired products from established manufacturers. No evidence of contamination in Emile Henry stoneware is on record.
Thermal shock and breakage
Stoneware pizza stones are susceptible to cracking if exposed to rapid temperature changes (e.g., moving from a hot oven directly into water). This is a mechanical failure risk rather than a chemical one but can create sharp edges and potential injury or food contamination if fragments enter food.
Coating degradation
This product has no synthetic coatings, enamels, or glazes on the cooking surface, eliminating the risk of chip-off or flaking common to glazed ceramics or nonstick cookware. The uncoated stoneware surface is inherently durable and does not degrade chemically with use.
Bacterial growth in porous surface
Stoneware is porous and can trap moisture and food residue if not dried thoroughly after washing. Poor drying practices or storage in damp conditions could promote bacterial growth, though this is a hygiene issue rather than a material toxicity concern. Regular hand washing and air drying mitigate this risk.
Teflon-type coating and nonstick fume risk
This uncoated stoneware product contains no Teflon-type coating, silicone, or other nonstick polymers, eliminating the risk of fume release at high temperature. Stoneware naturally resists sticking without chemical coatings.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 88% 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.
