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 King Arthur Baking.
- We flag Coating composition opacity (PFAS risk proxy) and Coating transfer to food under heat on the King Arthur Baking and not on the Calphalon.
- The Calphalon is Steel with PFA-free nonstick coating where the King Arthur Baking is paper with water-repellent coating, composition unspecified, 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.
- We are less certain about the King Arthur Baking grade, at 25% confidence against 72%, because it discloses less.
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 →
