White Subway-Tile Style Ceramic Tile by “Cabinet Concepts”: 110 +/- 17 ppm Lead (in substrate), safe by all standards.

When tested with an XRF instrument the tiles pictured here had the following readings:

Glazed surface of the tile:

• Barium (Ba): 548 +/- 105 ppm
• Zinc (Zn): 65,900 +/- 2,100 ppm
• Copper (Cu): 361 +/- 75 ppm
• Iron (Fe): 657 +/- 178 ppm
• Titanium (Ti): 214 +/- 68 ppm
• Zirconium (Zr): 22,100 +/- 900 ppm

Back (unglazed) side of the tile:

• Lead (Pb): 110 +/- 17 ppm
• Barium (Ba): 296 +/- 52 ppm
• Chromium (Cr): 155 +/- 67 ppm
• Zinc (Zn): 1,012 +/- 70 ppm
• Iron (Fe): 10,700 +/- 500
• Bismuth (Bi): 53 +/- 14 ppm
• Vanadium (V): 227 +/- 41 ppm
• Titanium (Ti): 2,409 +. 138 ppm
• Zirconium (Zr): 2,447 +/- 71 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.
