The kitchen is the room with the highest concentration of plastic-chemical exposure. Heat dramatically accelerates chemical leaching.
Why We Rated It This Way
Pyrex's glass containers are borosilicate glass — no BPA, no BPS, no phthalates. Glass is completely inert. Note: the plastic lids are BPA-free but still contain other plastic chemicals — avoid heating with lids on.
