January 2, 2023 – Monday
When I was in France (November 2022) I made sure to find and purchase several new items from major French brands (or items commonly found in France) to test and report on. This is one of the items I chose as an example. It is a small ceramic dish from the department store Monoprix [which is kind of like our Sears department stores]. Below are the XRF test results for this dish (as well as additional photos – showing that it was “Made in China” and the price was 4.99 Euros).
While I had hopes that this dish might be free of metallic toxicants [e.g. Lead, Cadmium, etc.] – or that it might test better than perhaps a similar item found in the United States…that was not the case! The white raised logo marking on the bottom of the dish (which you can feel with your finger as a slightly raised / rough area) was positive for a significant amount of Lead (just as painted logo markings on American-sold dishware counterparts often are).
Here are some articles highlighting the concern:
- Will this item poison me?
- But it is only a small amount of Leaded paint or glaze, why is that a problem?
- But it is only high Lead on the “outside” of the dish, why is that a problem?
- Some general background on the issue of Lead in glaze and other decorative elements of dishware.
Metals highlighted in red are generally considered toxic.
Metals highlighted in blue are not considered toxic in this application.

Tamara Rubin is a multiple-Federal-award-winning independent advocate for consumer goods safety, and a documentary filmmaker. She is also a mother of Lead-poisoned children. Tamara’s sons were acutely Lead-poisoned in August of 2005. 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. This year [2022], her work was also responsible for three CPSC product recalls — the Jumping Jumperoo recall (June, 2022); the Lead painted NUK baby bottle recall (July, 2022); and the Leaded Green Sprouts Insulated Stainless Steel Baby Bottles (November, 2022) — and she was recently featured in an NPR story about Lead in consumer goods (August, 2022); The Guardian (December, 2022); and an upcoming article in Consumer Reports (2023). Tamara uses 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 tested and reported on.

How does this work, for the numbers. There are two numbers mentioned , one is very high, the second is not as high. So which one is it?
The second number in a reading is the margin of error. So if something is 1000 +/- 100 ppm that means the margin of error is 100 ppm and the level is in the range of 900 and 1100 ppm. (900 = (1000-100) & 1100 = (1000 + 100))
Oh, I get it, that makes sense, thank you for the explanation.
Since it is often the logo marking on the bottom (like this one) that has the highest lead I am wondering if you tested the logo on the plain white corelle plates a lot of us have bought because they are supposed to be lead free? I would rub a swab on the logo (which often works on logos) but I just found out the 3M lead swabs are actually made of lead themselves!
Yes – there are test results for the Corelle logo on several of the posts with tests results for new corelle.
