Please stop using vintage Pyrex glassware for cooking & serving food – it’s often painted with high-Lead paint & can test positive for Cadmium & Arsenic, too.
“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 4 kids!]
“Old Town Blue” Pattern Vintage Pyrex Tea Cup, c.1972 – 1982: 17,700 ppm Lead [90 ppm is unsafe for kids.]
Vintage Pyrex Teacup & Saucer with Pink Stripe & Gold Edge: 79,800 ppm Lead [90 is unsafe] + Cadmium Too
