With scope focused on exterior green painted area:
(minimum 60-second test)
(minimum 60-second test)
- Lead (Pd): 65,200 +/- 2,300 ppm
- Cadmium (Cd): 200 +/- 26 ppm
- Chromium (Cr): 385 +/- 156 ppm
- Antimony (Sb): 699 +/- 66 ppm
- Bromine (Br): 52 +/- 16 ppm
- Gold (Au): 697 +/- 318 ppm
- Zinc (Zn): 33,600 +/- 1,200 ppm
- Iron (Fe): 415 +/- 175 ppm
- Titanium (Ti): 12,700 +/- 800 ppm
- Platinum (Pt): 1,152 +/- 269 ppm
- If a metal is not listed then it was not detected by the XRF in consumer goods mode.

With scope focused on plain white milk glass of bottom (image above):
(minimum 60-second test)
(minimum 60-second test)
- Lead (Pd): 1,128 +/- 65 ppm
- Cadmium (Cd): 30 +/- 11 ppm
- Antimony (Sb): 206 +/- 30 ppm
- Bromine (Br): 62 +/- 10 ppm
- Zinc (Zn): 79,600 +/- 2,300 ppm
- Iron (Fe): 541 +/- 135 ppm
- Titanium (Ti): 130 +/- 64 ppm
- If a metal is not listed then it was not detected by the XRF in consumer goods mode.
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, glaze or 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 this dish was positive for gold and platinum!]
NOTE: The outside paint on many of these vintage Pyrex pieces will also test positive for Lead 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.

Thank you for all your work. I’m 70, live aloneand have lots of Vintage Tupperware as I also sold it for a few years, 40 years ago. My question is how toxic is it now, given that I’ve been using it all this time. I also have the 70s Corning Ware casseroles and bowls and Pyrex clear bowls and glass measuring cups with the outside red lettering.
As I would have already been exposed for years, how much more harm is there in continuing to use them. I know you aren’t a Doctor and can’t really answer that unless I get blood tests, but any anecdotal information would be grateful. If I get rid of all the dish ware, bowls, mugs, I would have to replace my whole kitchen which I can’t afford to do – or switch to paper if I have people over.
I am getting rid of almost all my Tupperware as I use glass Pyrex or Anchor bowls with lids. I do have 2 young grandsons, and I make sure they do not play or use any of the dishes.
It certainly is a First world issue. I really do appreciate all your testing & work.
Thanks. Ann
