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 Instant Pot.
  • We flag PTFE thermal degradation and fume release, Coating peeling and microplastic ingestion, Aluminum leaching from basket substrate and Lack of material transparency and third-party validation on the Instant Pot and not on the Big Boss.
  • The Big Boss is borosilicate glass, bare uncoated where the Instant Pot is nonstick-coated cooking basket, material 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 Instant Pot 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 →
