Note: these are high-fire and likely non-leaching.

I was actually surprised to find the Lead and Cadmium levels on these pieces to be as low as they are; considering they are from Portugal, I would have expected much higher Lead levels.

Additionally, it is important to note that the testing component of the XRF instrument could not come in full direct contact with the designs on the concave interior surface of the bowls because the bowls are too small (relative to the size of the testing end of the XRF instrument) for flat purchase. That factor may impact the levels slightly (a test on a flat item of otherwise similar design, like a saucer or plate, may come up with slightly different Lead levels than found on these bowls). However, given there was full contact for the reading on the blue glaze on the exterior of the bowls (see first reading below), and given those levels are similar to the other levels found, I expect the readings noted below are fairly accurate (noting the margin of error).

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. 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. 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. Please click through to this link to learn more about the testing methodology used for the test results discussed and reported on this website.
