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.

A primary concern with tile like this is demolition.

Thanks for reading. Thank you for sharing my posts. As always – please let me know if you have any questions and I will do my best to answer them personally as soon as I have a moment (which may not be right away – but I will try!)
