Where these two actually differ
- We flag Silicone leaching (oligomers), Surface degradation and fragmentation and Bacterial colonization (if damaged) on the Dough Box and not on the GreenPan.
- We flag Silicone degradation and leaching, Color dyes or pigments in silicone and Bacterial growth in grip seams or joints on the GreenPan and not on the Dough Box.
- The Dough Box is silicone where the GreenPan is silicone, stainless steel handle, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
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 →
