Please stop using vintage Pyrex glassware for cooking & serving food — it’s often coated with high-Lead paint & can test positive for Cadmium, Arsenic
“If the Lead is only on the OUTSIDE (… of my dish, measuring cup, mixing bowl, etc.) why does it matter?”
“How much Lead is in my vintage Pyrex?” Here are pictures of each one I’ve tested, with links to test results.
Vintage Pyrex Honeydew Summer Impressions Custard Cup: 4,949 ppm Lead, 97 ppm Cadmium. 90 ppm Lead is unsafe for kids.
