Vintage Pyrex Spring Blossom Green “Crazy Daisy” Pattern Cups.
The dark green/almost black paint on these mugs tested positive for the following elements at the following levels (with a one-minute test, using an XRF instrument):
- Lead (Pb): 39,300 +/- 1,600 ppm
- Cadmium (Cd): 833 +/- 61 ppm
- Arsenic (As): ND
- Mercury (Hg): ND
- Platinum (Pt): 1,017 +/- 264 ppm
- Gold (Au): 492 +/- 273 ppm

For context, the amount of lead that is considered toxic to children in a newly manufactured item intended specifically for use by children is anything 90 ppm and higher (in the coating.)
Vintage dishware is not regulated at all for “total lead content as detectable with an XRF” and neither is modern dishware (yet.) [Isn’t it interesting that it was positive for gold and platinum!]
NOTE: When well used, most vintage Pyrex pieces will also usually test positive with a reactive agent test (like a LeadCheck swab: http://amzn.to/2DfE3ER*.)

Take away: if you can AVOID having functional vintage Pyrex pieces (or any vintage mugs or glasses) in your home, I would highly recommend that.
