When tested with an XRF instrument this Burgundy colored small plate by Longaberger Pottery had the following levels:
- Lead (Pb): 56 +/- 21 ppm
- Cadmium (Cd): 101 +/- 16 ppm
- Barium (Ba): 931 +/- 103 ppm
- Tin (Sn): 6,271 +/- 271 ppm
- Zinc (Zn): 76 +/- 29 ppm
- Copper (Cu): 210 +/- 59 ppm
- Iron (Fe): 1,132 +/- 236 ppm
- Bismuth (Bi): 76 +/- 21 ppm
- Vanadium (V): 1,086 +/- 79 ppm
- Titanium (Ti): 2,225 +/- 148 ppm
- Indium (In): 60 +/- 19 ppm
- Zirconium (Zr): 10,900 +/- 400 ppm
The level of Lead found in this plate is considered safe by all standards. The level of Cadmium is low, and it is common to find Cadmium in many red glazed items. It is slightly above some of the safety standards – but there is no specific safety standard for total Cadmium content in dishware as detectable with an XRF instrument.
Metals not listed were not detected by the XRF instrument. All tests were done for at least 60 seconds and levels were confirmed with multiple tests.
