For those new to the Lead Safe Mama website:
Tamara Rubin is a multiple-federal-award-winning independent advocate for childhood Lead poisoning prevention and consumer goods safety, and a documentary filmmaker. She is also a mother of Lead-poisoned children (two of her four sons were acutely Lead-poisoned in 2005).
- Tamara owns and runs Lead Safe Mama, LLC — a unique community collaborative woman-owned small business for childhood Lead poisoning prevention and consumer goods safety.
- Since July of 2022, the work of Lead Safe Mama, LLC has been responsible for five product recalls (FDA and CPSC).
- All test results reported on this website are science-based, accurate, and replicable.
- Please check out our press page to see some of the amazing coverage of our work so far this year!
In the interest of publishing quite a few test results quickly, we will be updating this article with more information shortly. For context: As of 2011, anything over 90 ppm Lead (in the paint, glaze, or coating of an item) is considered unsafe and illegal in items intended for use by children. Dishes are not considered items intended for use by children (on a U.S. federal level), so this level of Lead (in the glaze) on a food-use item is not illegal.
Reading #1) 60-second test
(repeated multiple times to confirm results)
On food surface of the dish
- Lead (Pb): 34 +/- 12 ppm
- Cadmium (Cd): non-detect
- Mercury (Hg): non-detect
- Bromine (Br): non-detect
- Chromium (Cr): 777 +/- 333 ppm
- Manganese (Mn): 351 +/- 201 ppm
- Iron (Fe): 9,179 +/- 382 ppm
- Cobalt (Co): 2,235 +/- 165 ppm
- Copper (Cu): 135 +/- 34 ppm
- Zinc (Zn): 2,645 +/- 102 ppm
- Zirconium (Zr): 7,443 +/- 182 ppm
- Tin (Sn): 17 +/- 10 ppm
- Barium (Ba): 955 +/- 53 ppm
- Platinum (Pt): 143 +/- 46 ppm
- Bismuth (Bi): 69 +/- 14 pp
- No other metals were detected in consumer goods mode.
Reading #2) 60-second test on the back of the dish
- The reading on the back of this dish was nearly identical to readings from the front of the dish.
- The Logo area did not contain any Lead beyond background ceramic levels.
