Where these two actually differ
- We flag Thermal shock and fracture and Edge chipping and glass fragments on the Big Boss and not on the Black+Decker.
- We flag Nonstick coating degradation and inhalation risk (thermal), Coating flaking into food (mechanical), Aluminum substrate leaching (if coating fails) and Bacterial growth in crevices if improperly maintained on the Black+Decker and not on the Big Boss.
- The Big Boss is borosilicate glass, bare uncoated where the Black+Decker is Non-stick coated cooking basket (type unspecified), which is most of the difference in these two grades.
- The gap is 60 points, wide enough that this is not a close call, and the Big Boss is the one to buy.
- We are less certain about the Black+Decker grade, at 35% confidence against 95%, 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 →
