Vintage Corelle glass saucer in the “Old Town Blue” pattern. The dark blue paint on this dish tested positive for the following elements at the following levels (with a one-minute test, using an XRF instrument):
- Lead (Pb): 18,200 +/- 400 ppm
- Cadmium (Cd): 133 +/- 13 ppm
- Arsenic (As): Non-Detect / Negative
- Mercury (Hg): Non-Detect / Negative
- Barium (Ba): Non-Detect / Negative
- Chromium (Cr): 3,433 +/- 164 ppm
- Antimony (Sb): Non-Detect / Negative
- Selenium (Se): Non-Detect / Negative
- Zinc (Zn): 94 +/- 24 ppm
- Copper (Cu): 106 +/- 41 ppm
- Nickel (Ni): 594 +/- 98 ppm
- Iron (Fe): 816 +/- 157 ppm
- Titanium (Ti): 5,290 +/- 260 ppm
- Zirconium (Zr): 3,256 +/- 96 ppm
- Platinum (Pt): 320 +/- 95 ppm
- Cobalt (Co): 4,890 +/- 252 ppm
- Magnesium (Mn): 770 +/- 256 ppm
- Gold (Au): Non-Detect / Negative
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 platinum!]
Take away: if you can AVOID having vintage dishes in your home, I would highly recommend that.
