PFAS score
Stoneline · Ceramic Cookware
Stoneline Xtreme Series 2016 Stock Pot
Skip until Stoneline discloses nonstick chemistry or switches to ceramic/stainless alternatives.
Stoneline's Xtreme Series uses a proprietary nonstick coating with no public disclosure of PFAS status. The brand does not claim PFAS-free certification or third-party verification. Without transparency on coating composition or lab testing, the PFAS risk profile cannot be reliably assessed.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
