When tested with an XRF instrument the orange and white Threshold brand dish (from Target) pictured here had the following readings:
Test focused on area of dish with orange glaze:
(this glaze is inside and outside of dish & had similar readings in both locations.)
- Cadmium (Cd): 384 +/- 25 ppm
- Barium (Ba): 2,040 +/- 122 ppm
- Selenium (Se): 126 +/- 21 ppm
- Copper (Cu): 296 +/- 59 ppm
- Iron (Fe): 3,231 +/- 311 ppm
- Bismuth (Bi): 66 +/- 20 ppm
- Vanadium (V): 2,121 +/- 119 ppm
- Titanium (Ti): 4.567 +/- 240 ppm
- Zirconium (Zr): 16,800 +/- 500 ppm
- Platinum (Pt): 220 +/- 61 ppm
Test focused on area of dish with orange and white patterned surface:
(readings on bottom over logo were similar for Lead and Cadmium content)
- Lead (Pb): 67 +/- 17 ppm
- Cadmium (Cd): 54 +/- 9 ppm
- Barium (Ba): 709 +/- 62 ppm
- Zinc (Zn): 83 +/- 23 ppm
- Copper (Cu): 254 +/- 48 ppm
- Iron (Fe): 2,841 +/- 260 ppm
- Bismuth (Bi): 80 +/- 16 ppm
- Vanadium (V): 1,722 +/- 97 ppm
- Titanium (Ti): 3,702 +/- 190 ppm
- Zirconium (Zr): 6,054 +/- 166 ppm
- Platinum (Pt): 118 +/- 47 ppm
Base ceramic/ stoneware, test focused on raised unglazed rim of bottom:
- Lead (Pb): 108 +/- 18 ppm
- Barium (Ba): 475 +/- 54 ppm
- Zinc (Zn): 253 +/- 35 ppm
- Copper (Cu): 224 +/- 46 ppm
- Iron (Fe): 4,580 +/- 318 ppm
- Bismuth (Bi): 121 +/- 18 ppm
- Zirconium (Zr): 3,149 +/- 88 ppm
Metals not detected by the XRF in “Consumer Goods” mode are not listed. Tests were done for a minimum of 60 seconds each to confirm the reading. Results are science-based and replicable and conducted with a Niton XL3T XRF in “Consumer Goods” mode.
As always, please let me know if you have any questions.
