With scope focused on the beige background:
- Lead (Pd): 94,800 +/- 3,800 ppm
- Cadmium (Cd): 435 +/- 47 ppm
- Antimony (Sb): 243 +/- 56 ppm
- Gold (Au): 645 +/- 281 ppm
- Zinc (Zn): 18,300 +/- 800 ppm
- Titanium (Ti): 19,500 +/- 1,200 ppm
- Zirconium (Zr): 3,579 +/- 213 ppm
- Platinum (Pt): 1,378 +/- 317 ppm
With scope focused on the white milk glass:
- Lead (Pd): 431 +/- 38 ppm
- Bromine (Br): 45 +/- 10 ppm
- Zinc (Zn): 76,700 +/- 2,100 ppm
- Iron (Fe): 958 +/- 156 ppm
- Titanium (Ti): 384 +/- 120 ppm
- Platinum (Pt): 542 +/- 198 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 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: The outside paint on many of these vintage Pyrex pieces will also 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 in your home (especially for functional applications/ daily use), 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: Thank you! https://www.gofundme.com/leadsafemama
Thank you for reading and for sharing my posts.
As always, please let me know if you have any questions.
Thanks so much for the information. I just found this dish at my mom’s and served vegetables in it last night. Guess I won’t be keeping it around. 🙁
