Brand New (2019 Open Stock at Fred Meyer) Corelle Prairie Garden Gray Dish: 16 ppm Cadmium (within safe levels.)

What are the exact XRF readings for this dish?

When tested with an XRF instrument the dish (brand new off the Fred Meyer shelf, purchased in 2019) pictured here (Made in the USA Corelle white glass with the “Prairie Garden Gray” pattern) had the following readings (note: given the shape of the dish and placement of the pattern it was difficult to get a single color in a reading):

Scope focused on a dark blue area of the dish:

• Cadmium (Cd): 15 +/- 6 ppm
• Chromium (Cr): 420 +/- 104 ppm
• Zinc (Zn): 573 +/- 45 ppm
• Iron (Fe): 686 +/- 131 ppm
• Vanadium (V): 793 +/- 92 ppm
• Titanium (Ti): 11,000 +/- 400 ppm
• Cobalt (Co): 506 +/- 84 ppm

Scope focused on a gray area of the dish:

• Cadmium (Cd): 16 +/- 7 ppm
• Chromium (Cr): 313 +/- 84 ppm
• Zinc (Zn): 141 +/- 27 ppm
• Iron (Fe): 688 +/’- 150 ppm
• Vanadium (V): 320 +/- 55 ppm
• Titanium (Ti): 4,415 +/- 226 ppm

All tests were done for a minimum of 60 seconds on a freshly calibrated instruments. Tests were repeated multiple times to confirm the results. Test results reported here on this blog are science-based and replicable.

Is Cadmium a problem?

Cadmium is a known carcinogen which, in my opinion, does not belong in any amount in any kitchenware (especially in the dishes we eat off of every day with our family!) This is one of the reasons I avoid the Corelle dishes with painted decorative elements (of any color.) You can read more about Cadmium toxicity here on this link. That said, the amount of Cadmium that is considered toxic and illegal in the country of Denmark (the only country I am aware of that has a total Cadmium content limit for consumer goods) is anything 75 ppm or higher. Washington State (here in the U.S.) has a Cadmium toxicity level (for consumer goods) of 40 ppm and higher. As a result the amount of Cadmium I detected in this dish is within safe levels by all current applicable standards.
