Hudson Park Collection "Made In China" white ceramic plate with gold back mark: 171 ppm Lead on back mark.

When tested with an XRF instrument (60 seconds per test) this Hudson Park Collection white ceramic plate with a gold back mark had the following readings:

Food surface of the plate:

Lead (Pb): 42 +/- 16 ppm
Second Reading – Lead: 47 +/- 15 ppm
Mercury (Hg): Negative / Non-Detect
Cadmium (Cd): Negative / Non-Detect
Arsenic (As): Negative / Non-Detect
Antimony (Sb): Negative / Non-Detect
Barium (Ba): 2,961 +/- 145 ppm
Zinc (Zn): 57,500 +/- 1,600 ppm
Iron (Fe): 760 +/- 148 ppm
Vanadium (V): 2,110 +/- 156 ppm
Titanium (Ti): 4,598 +/- 286 ppm
Zirconium (Zr): 3,572 +/- 121 ppm
Platinium (Pt): 351 +/- 164 ppm

Test focused on gold back mark:

Lead (Pb): 171 +/- 24 ppm
Mercury (Hg): Negative / Non-Detect
Cadmium (Cd): Negative / Non-Detect
Arsenic (As): Negative / Non-Detect
Antimony (Sb): Negative / Non-Detect
Barium (Ba): 2,247 +/- 124 ppm
Zinc (Zn): 55,600 +/- 1,600 ppm
Iron (Fe): 2,609 +/- 239 ppm
Vanadium (V): 2,009 +/- 158 ppm
Titanium (Ti): 5,880 +/- 343 ppm

Each test was done using a freshly calibrated XRF instrument in “Consumer Goods” mode. Testing was repeated on each component to confirm the results. Testing time for each component was for at least 60 seconds. Results are replicable, science-based, and accurate. Metals not listed in the above test results sets were not detected by the XRF when testing in Consumer Goods mode.

The Lead level on the food surface of this dish is safe by all current federal standards (under 90 ppm Lead in the paint, glaze or coating is considered safe for items intended for use by children – for example.) My readers have differing opinions as to whether or not higher Lead levels in back marks present a concern. I found dishes in my home where the back mark was positive for more than 6,000 ppm Lead and, even though the food surface of the dish was negative for Lead, I chose to dispose of those dishes. Click this link to see those dishes. At the level found on the Hudson Park dish pictured here in this post (in the 150 to 200 ppm range) it is not as much of a concern – however, on principle, I personally don’t think I would choose to keep these dishes in my home.

Thank you for reading and for sharing my posts.

Please let me know if you have any questions.
