Where these two actually differ
- We flag Nonstick coating degradation over time, Coating fume release at high temperature and Microplastics from coating shedding on the Calphalon and not on the Kirkland Signature.
- We flag Silicone coating degradation at high heat and Undisclosed processing chemicals in coating manufacture on the Kirkland Signature and not on the Calphalon.
- The Calphalon is Steel with PFA-free nonstick coating where the Kirkland Signature is Silicone-coated paper (presumed), which is most of the difference in these two grades.
- The gap is 70 points, wide enough that this is not a close call, and the Calphalon is the one to buy.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
