When tested with an XRF Instrument this dish had the following readings:
On the food surface of the dish:
60-second test
- Lead (Pb): 18,400 +/- 500 ppm
- Cadmium (Cd): 16 +/- 7 ppm
- Barium (Ba): 158 +/- 43 ppm
- Bismuth (Bi): 131 +/- 45 ppm
- Tin (Sn): 494 +/- 26 ppm
- Zinc (Zn): 329 +/- 38 ppm
- Iron (Fe): 1,000 +/- 169 ppm

As always, thank you for reading and for sharing my posts. Please let me know if you have any questions and I will do my best to answer them personally (as soon as I have a moment.)

Thank you for doing this testing. Did you test the blue version of this dish? If not, can I assume the lead content of the blue version would give the same or similar results?
Lots! If you put “blue willow” in the search bar or click the “blue willow” keyword at the top of the page you will see quite a few examples.
Have you tested the Currier and Ives blue dishes by this same company: Royal China in Sebring, OH? It was mass produced for daily use and still widely used. I haven’t been able to find anything about it with a google search.
Yes – results are similar – typically in the 20,000 to 40,000 ppm range.
