Glass Meal Prep Set vs Brilliance StainShield Plastic Food Storage Containers: which is safer?
Pyrex Glass Meal Prep Set is the clear pick. Rubbermaid Brilliance StainShield Plastic Food Storage Containers carries a failing PFAS grade, and we never recommend buying a failing product.

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 Fluorinated coating leachates (likely PFAS-containing stain treatment), Coating degradation and migration, Microplastic shedding from wear and Heat-induced leaching from coating 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 Polypropylene (PP) plastic with stain-resistant treatment, which is most of the difference in these two grades.
- The gap is 55 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 →
