When tested with an XRF instrument the tiles pictured here had the following readings:
Glazed surface of the tile:
- Barium (Ba): 162 +/- 55 ppm
- Chromium (Cr): 950 +/- 94 ppm
- Zinc (Zn): 10,600 +/- 400 ppm
- Copper (Cu): 120 +/- 43 ppm
- Nickel (Ni): 230 +/- 77 ppm
- Iron (Fe): 1,825 +/-217 ppm
- Vanadium (V): 202 +/- 36 ppm
- Titanium (Ti): 571 +/- 66 ppm
- Zirconium (Zr): 4,268 +/- 126 ppm
- Cobalt (Co): 963 +/- 133 ppm
Back (unglazed) side of the tile:
- Barium (Ba): 85 +/- 41 ppm
- Zinc (Zn): 115 +/- 22 ppm
- Iron (Fe): 5,329 +/- 302 ppm
- Bismuth (Bi): 24 +/- 10 ppm
- Vanadium (V): 167 +/- 35 ppm
- Titanium (Ti): 2,074 +/- 118 ppm
- Platinum (Pt): 75 +/- 35 ppm
Metals not detected 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.

Greetings, I’m new to your site (my wife is not) and am not familiar how to navigate here. What is the name / brand of this particular tile? Thanks.

Hi Steven,
I don’t have that information – sorry. Sometimes people don’t include that when they send me samples, but I post them anyway in case someone has something similar (as a potential point of comparison.)
Here’s how the testing on my site works: https://tamararubin.com/2017/07/subscribe-in-support-of-my-advocacy-work-you-can-become-eligible-to-send-in-a-box-of-your-things-for-testing/

Hello,
We have wood look ceramic tile. So, on these readings, is the chromium or any of the readings a health hazard?
