Introduction
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.

Wow!! Cannot believe these results I am SO glad I sent this for testing. I was told by THREE different pottery barn associates that these plates were lead FREE. I am boycotting pottery barn. Thank you, Tamara for your amazing work in ensuring we know the real truth of lead levels in our home products 🙂
Oh no. These have been the family dishes for a decade. I wish your work would go mainstream so these stores would stop selling these products.
Thank you.
