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. Tamara’s work was featured in Consumer Reports Magazine in February of 2023.
When tested with an XRF instrument, this brass metal sheeting (sold for hobby projects at the local hardware store) had the following readings:
- Zinc (Zn): 308,800 +/- 2,500 ppm
- Copper (Cu): 689,800 +/- 3,200 ppm
- Vanadium (V): 328 +/- 143 ppm
This material was tested for a minimum of 60 seconds for each (repeated) test to make sure to report the most accurate possible reading.
I will update this post with more information shortly, but in the meantime – please read some of the other posts I have written to understand better the test results reported on this website.
As always – thank you for reading and for sharing my posts.
Please let me know if you have any questions.

Thank you for testing this! Is there a link to buy this specific product? A google search takes me to generic products at big box stores…..
I bought some of this metal, one sheet of brass and one sheet of copper…at the local True Value store. Also you can get it here:
