When tested with an XRF instrument (with repeated tests on each component, for a minimum of 60 seconds per test) the small Oneida Culinaria ceramic bowl (with a sort of beige colored glaze) pictured here had the following readings:
Food surface of the bowl:
- Zinc (Zn): 25,300 +/- 800 ppm
- Copper (Cu): 218 +/- 57 ppm
- Iron (Fe): 526 +/- 164 ppm
- Vanadium (V): 82 +/- 31 ppm
- Titanium (Ti): 278 +/- 54 ppm
- Zirconium (Zr): 12,900 +/- 400 ppm
Logo on bottom of the bowl:
- Lead (Pb): 33 +/- 16 ppm
- Chromium (Cr): 7,681 +/- 285 ppm
- Zinc (Zn): 21,500 +/- 700 ppm
- Copper (Cu): 239 +/- 57 ppm
- Nickel (Ni): 1,131 +/- 121 ppm
- Iron (Fe): 3,568 +/- 291 ppm
- Vanadium (V): 84 +/- 34 ppm
- Titanium (Ti): 240 +/- 54 ppm
- Zirconium (Zr): 10,400 +/- 300 ppm
- Cobalt (Co): 1,540 +/- 168 ppm
