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.
Vintage Pyrex “Made In USA” orange mixing bowl:
61,100 ppm lead when tested with an XRF instrument.
Notice all the flecks of paint (leaded paint) missing from this vintage Pyrex mixing bowl! I love this image. I illuminated the bowl from the inside to show the worn/chipped exterior finish.
Please share and browse the photo library of this site (click on the #XRFTesting tag in the tag list at the top of the post) to see items I have personally tested that have tested both positive and negative for lead.
As always, thank you for reading and for sharing my posts.
Please let me know if you have any questions.
