Tamara Rubin is an independent advocate for consumer goods safety and she is also a mother of Lead-poisoned children. She began testing consumer goods for toxicants in 2009 and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. She uses XRF testing (a scientific method used by the Consumer Product Safety Commission) to test consumer goods for contaminants including Lead, Cadmium, Mercury and Arsenic.

XRF test results for the tile pictured. Tests were repeated multiple times to confirm the results and done for a minimum of 60 seconds each.
#1.) Glazed front of the tile
- Lead (Pb): 531,800 +/- 15,000 ppm
- Cadmium (Cd): 443 +/- 36 ppm
- Bromine (Br): 514 +/- 89 ppm
- Chromium (Cr): 1,566 +/- 183 ppm
- Vanadium (V): 2,247 +/- 433
- Iron (Fe): 11,800 +/- 400 ppm
- Zinc (Zn): 114,100 +/- 3,300 ppm
- Titanium (Ti): 3,017 +/- 540 ppm
- Tin (Sn): 309 +/- 46 ppm
- Barium (Ba): 1,351 +/- 222 ppm
- Gold (Au): 1,333 +/- 199 ppm
- Bismuth (Bi): 3,821 +/- 461 ppm
- no other metals detected
- Second test Lead level: 556,900 +/- 16,000 ppm [test on a slightly darker spot]
#2.) Reddish (terra cotta) unglazed backside (bare clay) of the tile
- Lead (Pb): 843 +/- 18 ppm
- Chromium (Cr): 794 +/- 109 ppm
- Manganese (Mn): 691 +/- 77 ppm
- Iron (Fe): 45,100 +/- 500 ppm
- Nickel (Ni): 655 +/- 36 ppm
- Zinc (Zn): 386 +/-15 ppm
- Barium (Ba): 153 +/- 14 ppm
