Introduction (for those new to this website):
Tamara Rubin is a federal-award-winning independent advocate for consumer goods safety and a documentary filmmaker. She is also a mother of Lead-poisoned children, her sons were acutely Lead-poisoned in 2005. Since 2009 Tamara has been using XRF testing (a scientific method used by the U.S. Consumer Product Safety Commission) to test consumer goods for toxicants (specifically heavy metals), including Lead, Cadmium, Mercury, Antimony, and Arsenic. All test results reported on this website are science-based, accurate, and replicable. Items are tested multiple times, to confirm the test results for each component tested. Tamara’s work was featured in Consumer Reports Magazine in February of 2023.
Test on exterior red writing:
- Cadmium (Cd): 396 +/- 29 ppm
- Selenium (Se): 79 +/- 46 ppm
- Zinc (Zn): 17,300 +/- 800 ppm
- Iron (Fe): 1,431 +/- 287 ppm
- Chromium (Cr): 1,682 +/- 177 ppm
- Titanium (Ti): 2,822 +/- 284 ppm
Test on plain clear glass – on bottom exterior of cup:
- Cadmium (Cd): 18 +/- 10 ppm
- Titanium (Ti): 169 +/- 70 ppm
- Palladium (Pd): 9 +/- 6 ppm
- The Cadmium in this test may be from trace micro dust contaminating the surface as a result of deterioration of the red writing on other parts of the glass.
Test on plain clear glass – on pour spout/lip:
- Titanium (Ti): 134 +/- 52 ppm
