Where these two actually differ
- We flag Ceramic coating degradation and flaking and Aluminum leaching on the GreenPan and not on the GreenPan.
- We flag Nonstick coating degradation and aluminum leaching, Fume risk from unknown coating additives at elevated heat, Microparticle shedding from coating wear and Lack of third-party verification for health claims on the GreenPan and not on the GreenPan.
- The GreenPan is Ceramic-based nonstick coating where the GreenPan is Nonstick coating (composition not disclosed), 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 GreenPan is the one to buy.
- We are less certain about the GreenPan grade, at 35% confidence against 72%, 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 →
