White Ceramic Bone China Fine Porcelain Dowan Bowl: 35 ppm Lead + 17 ppm Cadmium (safe by all standards).

This product is marketed online and sold as “Lead Free” on Amazon (below is a screenshot from the Amazon listing for this product taken on 3/25/2019 – 7:50 p.m.):

When tested with an XRF instrument this white ceramic bowl had the following readings (with a one-minute test in consumer goods mode):

Inside food surface of bowl:

  • Lead (Pb): 35 +/- 12 ppm
  • Cadmium (Cd): 17 +/- 8 ppm
  • Zinc (Zn): 16,400 +/- 500 ppm
  • Iron (Fe): 1,165 +/- 166 ppm
  • Vanadium (V): 160 +/- 36 ppm
  • Titanium (Ti): 432 +/- 62 ppm
  • Indium (In): 43 +/- 11 ppm

The bottom logo area (black image and writing) had the following readings:

  • Barium (Ba): 1,602 +/- 177
  • Selenium (Se): 35 +/- 14 ppm
  • Zinc (Zn): 8,811 +/- 133 ppm
  • Iron (Fe): 501 +/- 41 ppm
  • Bismuth (Bi): 49 +/- 10 ppm

The levels of Lead and Cadmium found on the inside surface of this bowl are within safe levels by all standards. While there is not a regulatory restriction for total Lead or Cadmium content in new (or vintage) dishware in the United States, I like to share the regulatory standards for toys, which are the only relevant regulations when it comes to XRF detectable levels of metals. In my opinion dishes should be regulated at least to the same strict levels as toys. Below is a chart from the following study (link) that shows acceptable limits of these toxicants:

As always, thank you for reading and for sharing my posts.

Please let me know if you have any questions.
