Where these two actually differ
- We flag Metal lid corrosion and leaching, Silicone or rubber gasket degradation and Thermal shock fracture from glass on the Pyrex and not on the Rubbermaid.
- We flag Microplastics from degradation, Heat-induced leaching, Lid seal degradation and Mold/bacterial growth from poor ventilation on the Rubbermaid and not on the Pyrex.
- The Pyrex is borosilicate glass with metal lids (likely stainless steel or aluminum) where the Rubbermaid is BPA-free plastic (polypropylene/copolyester blend), 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 Pyrex 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 →
