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?”
Vintage pink Pyrex refrigerator dish: 179,000 ppm Lead (nearly 18%!!!) + 7,003 ppm Cadmium and 12,300 Arsenic!
Vintage clear glass small Pyrex casserole: 866 +/- 61 ppm Arsenic (this is the first time I have found Arsenic in one of these)
Vintage Pyrex Spring Blossom Green Crazy Daisy Mixing Bowls: 109,900 ppm Lead (90 is unsafe) + Cadmium too!
