When tested with an XRF instrument, the tile pictured here had the following readings (metals not listed were not detected, tests were completed for a minimum of 60 seconds each):
- Lead (Pb): 37 +/- 15 ppm
- Barium (Ba): 1,590 +/- 89 ppm
- Chromium (Cr): 1,594 +/- 155 ppm
- Zinc (Zn): 8,862 +/- 315 ppm
- Copper (Cu): 121 +/- 44 ppm
- Iron (Fe): 3,628 +/- 303 ppm
- Vanadium (V): 5.491 +/- 246 ppm
- Titanium (Ti): 11,600 +/- 500 ppm
- Zirconium (Zr): 4,071 +/- 124 ppm
- Cobalt (Co): 867 +/- 124 ppm
- Manganese (Mn): 820 +/- 305 ppm
Test results are only accurate and true for the EXACT specific tile pictured (above). Please realize that — with glazed ceramics especially — glazing and base ceramic formulations can change from time-to-time, which means a later or earlier version of this same tile could possible have different test results for the presence (or absence) of toxicants. That said, IF the tile is generally the same (similar year of manufacture, same pattern, serial number and brand, for example) it is a reasonable educated guess to conclude the XRF test results for that product could likely be expected to be similar to what we have reported here.
For the ceramic tiles Lead Safe Mama has tested (and reported here in this “TileBar” series), the readings above are the glazed/ decorated surface of the tile (not the back/ base ceramic of the tile). If not otherwise noted, I also tested the back side of the ceramic tile (the unglazed base ceramic) and found Lead levels to be either “ND” (non-detect) or far below the surface level of Lead on the tile — an indicator that the Lead is definitely in the glaze/ decorative design elements of these specific tiles.

Please note that new, modern tile is NOT currently REGULATED for total Lead content (nor other toxicants), and you can not make assumptions like “it’s new, so it should be Lead-free.” That said, manufacturers are getting smart — using less Lead and making their manufacturing processes more transparent — so it is always possible to make an inquiry with the manufacturer about the presence or absence of toxicants like Lead, Mercury, Cadmium, and Arsenic (depending on the manufacturer or vendor, the company may or may not know — but it’s worth a call).
Please note: In my experience, man-made items — manufactured glass and ceramic tiles — are likely to have at least some Lead. Natural materials (stone, marble, slate), on the other hand, are unlikely to test positive for any heavy metals.
The main concern with finding toxicants in any tile is the concern for dust — created during demolition or remodeling — and breakage or damage, whether from run-of-the-mill accidents (or disasters such as fire, fallen trees, tornadoes, earthquakes, etc). It also raises a concern over the need to observe responsible/ strict manufacturing practices to avoid potential worker exposure to toxicants during the fabrication process.
As always, thank you for reading and sharing these articles.
