Tamara Rubin is a Federal award winning independent advocate for consumer goods safety and childhood Lead poisoning prevention. 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 metallic toxicants (including Lead, Cadmium, Mercury and Arsenic).

First – A Video!
Here’s a short (3-minute) video I made in which I discuss this dish and test it for Lead using a LeadCheck Swab. It is important to note that MOST dishes will not test positive with a LeadCheck Swab even if they are positive for high levels of Lead. Those that do are especially dangerous. The swabs were not designed to test dishes (you can read more about that on this link.) Because the swabs were specifically designed to test for Lead in house paint, IF a dish does not test positive with a swab that does not mean it is necessarily safe and it also does not mean the swabs do not work.
Full XRF Test Results For The Dish Pictured
Test on the food surface of the Stangl brand vintage / antique dish pictured
- Lead (Pb): 504,700 +/- 14,000 ppm
- Cadmium (Cd): 548 +/- 44 ppm
- Mercury (Hg): non-detect
- Bromine (Br): non-detect
- Chromium (Cr): 1,375 +/- 189 ppm
- Iron (Fe): 1,561 +/- 125 ppm
- Nickel (Ni): 175 +/- 64 ppm
- Copper (Cu): 946 +/- 125 ppm
- Zinc (Zn): 284 +/- 35 ppm
- Tin (Sn): 11,200 +/- 300 ppm
- Antimony (Sb): 56,500 +/- 1,600 ppm
- Barium (Ba): 7,496 +/- 364 ppm
- No other metals detected
This is what a LeadCheck swab looks like when used on this plate (the bright red/pink one on the left is from this dish, the light pink result on the right is from a newer glass Pyrex bottle that had Lead paint on the outside – paint that came in at about 19,000 ppm Lead – link):
