PFAS score
Granite Ware · Pizza Stones & Ceramic Bakeware
As Seen On Tv Granitestone Piezano Replacement Stone
Skip until brand clarifies coating chemistry and PFAS status.
Granite Ware's 'stone' cookware line markets a mineral-look nonstick surface but discloses neither the coating type nor PFAS presence/absence. 'Stone' branding is vague marketing, the actual binder and any Teflon-family coating content remain undisclosed.

Why this grade
Non-stick, chemistry undisclosed

Category baseline
cookware is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
