PFAS score
Pyrex · Pizza Stones & Ceramic Bakeware
15" Ceramic Pizza Stone
Lower concern; ceramic pizza stones are PFAS-free by material nature.
Pyrex's ceramic pizza stone is made from fired clay, an inherently PFAS-free material with no nonstick coatings or water-resistant treatments applied. Pyrex does not claim PFAS-free status, but ceramic cookware poses minimal PFAS risk. No public lab testing found; material composition is the reassurance here.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 92% 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.
