When tested with an XRF instrument the tiles pictured here had the following readings:
Glazed surface of the tile:
- Iron (Fe): 428 +/- 138 ppm
- some readings were also negative for all metals (depending on the color-range of the glaze captured in the scope of the XRF.)
Back (unglazed) side of the tile:
- Vanadium (V): 77 +/- 25 ppm
- Titanium (Ti): 70 +/- 29 ppm
All color variations of the tile shown were tested.
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.
