Vintage Corelle Blue & Yellow Flower Pattern Dish with Butterflies (year of manufacture unknown).
When tested with an XRF instrument the painted decorative border on the food surface of this vintage Corelle plate was positive for a very high level of Lead. To see the full XRF readings for this exact plate, scroll down. Note: I don’t know the exact year of manufacture of this piece as it was purchased second hand at Good Will. If you have information about the year of manufacture (or year-range) for this pattern, please comment here on this post.

As a mother of Lead-poisoned children and as an environmental activist, I have taken the stand that there is no place for any amount of Lead on our dining tables. None at all.
It literally just takes a microscopic amount of Lead to poison a child (or any human for that matter) and, as of the moment of publishing this post, there is NO ONE (no individual, company, educational institution or other agency) studying the potential impact that eating off of Leaded vintage dishware has on the users (because no corporation stands to benefit financially from such a study). Consequently, as consumers we need to err on the side of prudence, and proactively remove all potential sources of Lead exposure from our homes ourselves, starting with our kitchens.

These particular dishes tested positive for 41,500 ppm Lead.
For context to better understand what this level of Lead means; the amount of XRF detectable 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, finish 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 (as detectable with an XRF) in the same way as toys and other similar children’s items (unless they are dishes expressly marketed and sold as baby dishes – manufactured after 2010.] In my opinion, they should be.

All tests reported on this blog were done for at least 60 seconds each (unless otherwise noted), using an XRF instrument. The XRF instrument used in the testing is a Niton XL3T, a scientific instrument specifically designed and intended expressly for testing consumer goods for Lead and other metals. The results are science-based, replicable and accurate.
Decorative Edge / Food Surface (image above):
- Lead (Pb): 41,500 +/- 1,200 ppm
- Cadmium (Cd): 659 +/- 44 ppm
- Zinc (Zn): 361 +/- 53 ppm
- Copper (Cu): 126 +/- 54 ppm
- Titanium (Ti): 9,349 +/- 504 ppm
- Zirconium (Zr): 2,896 +/- 124 ppm
- Platinum (Pt): 461 +/- 170 ppm
Plain White Center of Plate / Food Surface:
- Iron (Fe): 404 +/- 129 ppm
- Vanadium (V): 93 +/- 26 ppm
- Titanium (Ti): 127 +/- 33 ppm
