Where these two actually differ
- We flag Microplastic shedding from wear, Lid seal degradation leading to mold or bacterial growth and Chemical absorption and odor/flavor transfer on the OXO and not on the Pyrex.
- 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 OXO.
- The OXO is Plastic (polypropylene/polycarbonate) food storage containers and lids where the Pyrex is borosilicate glass with metal lids (likely stainless steel or aluminum), which is most of the difference in these two grades.
Both products run through the same public rubric, which covers 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 →
