When tested with an XRF instrument, this miniature ceramic Starbucks cup Christmas ornament with red and green glazed / printed decorations and a red ribbon – purchased new at a Starbucks store in Washington State in 2019 – had the following readings:
- Cadmium (Cd): 529 +/- 37 ppm
- Chromium (Cr): 10,100 +/- 400 ppm
- Selenium (Se): 97 +/- 38 ppm
- Lead (Pb): Non-Detect / Negative
- Barium (Ba): Non-Detect / Negative
- Mercury (Hg): Non-Detect / Negative
- Arsenic (As): Non-Detect / Negative
- Antimony (Sb): Non-Detect / Negative
All tests were done for a minimum of 60 seconds each – using a freshly calibrated Niton XRF instrument (an XL3T XRF testing in “Consumer Goods” mode). Tests were repeated multiple times to confirm the results. All test results reported on this blog are science-based, accurate, and replicable.
