Where these two actually differ
- We flag Nonstick coating degradation and fume risk, Coating integrity loss over time and Proprietary coating composition undisclosed on the Calphalon and not on the GreenPan.
- We flag Ceramic coating degradation and peeling, Aluminum leaching from base metal and Coating adhesion loss and metal exposure on the GreenPan and not on the Calphalon.
- The Calphalon is Hard-anodized aluminum with proprietary nonstick coating (unspecified) where the GreenPan is ceramic nonstick coating, which is most of the difference in these two grades.
- The gap is 75 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
- We are less certain about the Calphalon grade, at 35% confidence against 82%, because it discloses less.
Both products run through the same public rubric: 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 →
