Please stop using vintage Pyrex glassware for cooking & serving food — it’s often coated with high-Lead paint & can test positive for Cadmium, Arsenic
“How much Lead is in my vintage Pyrex?” Here are pictures of each one I’ve tested, with links to test results.
Vintage Spring Blossom Green “Crazy Daisy” Pyrex cup: 39,300 ppm Lead + 833 ppm Cadmium (90 ppm Pb is unsafe for kids!)
