Vintage Pyrex Mugs: The blue 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): 71,800 +/- 2,200 ppm
- Cadmium (Cd): 697 +/- 43 ppm
- Arsenic (As): ND
- Mercury (Hg): ND
- Platinum (Pt): 1,333 +/- 207 ppm
- Gold (Au): 709 +/- 146 ppm
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 paint or coating.)
–
Vintage dishware is not regulated at all for “total lead content as detectable with an XRF” and neither is modern dishware regulated for total lead content measured in this way (yet.)
–
Isn’t it interesting that these mugs are also positive for gold and platinum!
–
NOTE: When well used, these vintage Pyrex pieces will also usually test positive with a reactive agent test (like a LeadCheck swab: http://amzn.to/2DfE3ER affiliate link*).
–
Take away: if you can AVOID having vintage Pyrex (or any vintage mugs or glasses) in your home, I would highly recommend that.

Do you appreciate my independent consumer goods testing and childhood lead poisoning prevention advocacy work? If so, please consider contributing to my GoFundMe, to help me to continue to be in a position to do this kind of testing (it normally costs $1,500 to $2,000 a week to rent the instrument I use for testing!) Here’s my GoFundMe link. Even $5 or $10 makes a difference. Thank you! https://www.gofundme.com/leadsafemama

How do you recommend disposing of these dishes?
But I just got into pyrex a few months ago. :”(
I’m so sorry! Julie check out this post: https://tamararubin.com/2020/07/if-the-lead-is-only-on-the-outside-of-my-dish-measuring-cup-mixing-bowl-etc-why-does-it-matter-that-it-has-lead/

Wow. I had those blue cups and donated them. I’m wondering about Corelle’s Indian Harvest pattern.
Yes – that pattern is also very high lead.
