When tested with an XRF instrument the mug pictured here had the following readings:
Test focused on area of mug with black stripe:
- Lead (Pb): 6,300 +/- 157 ppm
- Barium (Ba): 184 +/- 50 ppm
- Chromium (Cr): 791 +/- 104 ppm
- Tin (Sn): 48 +/- 15 ppm
- Zinc (Zn): 11,500 +/- 300 ppm
- Iron (Fe): 1,606 +/- 182 ppm
- Bismuth (Bi): 58 +/- 27 ppm
- Vanadium (V): 561 +/- 54 ppm
- Titanium (Ti): 802 +/- 77 ppm
- Cobalt (Co): 1,576 +/- 139 ppm
- Mn: 954 +/- 233 ppm
Test focused on area of mug with only plain white glaze:
- Lead (Pb): 138 +/- 17 ppm
- Barium (Ba): 162 +/- 44 ppm
- Zinc (Zn): 12,800 +/- 300 ppm
- Iron (Fe): 1,476 +/- 166 ppm
- Bismuth (Bi): 87 +/- 16 ppm
- Vanadium (V): 109 +/- 29 ppm
- Titanium (Ti): 348 +/- 51 ppm
Metals not detected by the XRF in “Consumer Goods” mode are not listed. Tests were done for a minimum of 60 seconds each to confirm the reading. Results are science-based and replicable and conducted with a Niton XL3T XRF in “Consumer Goods” mode.
As always, please let me know if you have any questions.
Thank you for reading and for sharing my posts.
Hi,
I just called Corelle and they insist their products are 0.1 ppm. Is the mug you tested here a new mug, or something that was bought a while ago? Just trying to figure this out.
Many thanks
Hi Joe,
I don’t know the exact year of purchase for the mug, it is an item sent in by one of my readers.
Thanks for commenting.

I have the white Corelle with the black stripes. I have the mugs, plates, and bowls. Are they safe?
