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 Pyrex.
- We flag Plastic lid degradation and microplastic release and Borosilicate glass thermal shock fracture on the Pyrex and not on the Pyrex.
- The Pyrex is borosilicate glass with metal lids (likely stainless steel or aluminum) where the Pyrex is borosilicate glass container, plastic lids (likely polypropylene or polyethylene), which is most of the difference in these two grades.
