Where these two actually differ
- We flag Ceramic coating degradation over time on the Caraway and not on the Mirro.
- We flag PTFE fume risk (nonstick coating), Aluminum leaching and Coating degradation over time on the Mirro and not on the Caraway.
- The Caraway is ceramic nonstick coating where the Mirro is aluminum with nonstick PermaCote coating, unspecified fluoropolymer, which is most of the difference in these two grades.
- The gap is 85 points, wide enough that this is not a close call, and the Caraway is the one to buy.
- We are less certain about the Mirro grade, at 35% confidence against 92%, 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 →
