PFAS score
Pyrex · Pizza Stones & Ceramic Bakeware
World Market Red Glazed Pizza Stone
Lower PFAS concern, uncoated ceramic pizza stone unlikely to contain PFAS.
Pizza stones are typically fired clay or stoneware with glazed surfaces, materials not inherently associated with PFAS chemistry. Pyrex has not disclosed PFAS concerns for this product, and ceramic cookware generally avoids the Teflon-family coating coatings linked to PFAS.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
