Williams Sonoma Goldtouch Nonstick Muffin Pan
Skip until manufacturer discloses nonstick chemistry or reformulates.
Williams Sonoma's Goldtouch (made by Pyrex) is a hard-anodized nonstick muffin pan with no public disclosure of the coating's chemistry or PFAS status. Pyrex does not claim PFAS-free formulation. Without third-party lab testing or brand transparency, the nonstick layer's PFAS risk remains unknown and warrants caution.

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.
