Each of the small images below is a link to an article with the test results for the dish pictured.
This article discusses the dish below (and specifically XRF test results for heavy metals for this dish).

Full XRF test results for the vintage “Meadow” pattern Corelle dish pictured are below.
For additional information please check out the following articles:
- More Corelle dishware I have tested
- Article discussing Corelle representative’s statement that pre-2005 dishware should be retired from food-use purposes

- No other metals detected in consumer goods mode. All tests are repeated multiple times to confirm the results.
How much Lead is “too much” Lead?
The painted / decorative elements on these particular dishes tested positive for 16,700 ppm Lead. For context, the amount of Lead that is considered toxic in a newly manufactured item “intended for use by children” is anything 90 ppm Lead or higher in the paint, glaze or coating, and anything 100 ppm Lead or higher in the substrate. Dishes (modern or vintage) are not considered to be items “intended for use by children”, and thus are not regulated for total lead content in the same way as toys and other similar children’s items (unless they are dishes expressly manufactured, marketed and sold as children’s dishes after 2010.)
Why is this much Lead a problem?
As both a mother of Lead-poisoned children and as an environmental activist, I have taken the stand that there is no place for Lead on our dining tables (or in our kitchens.) None at all.
It literally just takes a microscopic amount of Lead to poison a child (or any human for that matter) and there is currently (at the time of publishing this article) NO ONE studying the potential impact that eating off of Leaded vintage dishware has on the users (because no corporation has identified a direct financial benefit from such a study). Consequently. given Lead’s extreme toxicity, we need to err on the side of prudence, and proactively remove all potential sources of Lead exposure from our homes ourselves, starting with the easy stuff -like the dishes we choose to eat off of every day.

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 and reported on.
