Introduction:
Tamara Rubin is a Federal award winning independent advocate for consumer goods safety and childhood Lead poisoning prevention. She is also a mother of Lead-poisoned children. She began testing consumer goods for toxicants in 2009, and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. She uses XRF testing (a scientific method used by the Consumer Product Safety Commission) to test consumer goods for metallic toxicants (including Lead, Cadmium, Mercury and Arsenic).

Short (3-minute) video discussing this tea cup:
September 6, 2021 – Monday
XRF test results for the Spode Copeland’s China tea cup pictured
Reading #1) focus on purple flower
60-second reading

- Cadmium (Cd): non-detect
- Mercury (Hg): non-detect
- Bromine (Br): non-detect
- Chromium (Cr): 604 +/- 101 ppm
- Manganese (Mn): 535 +/- 70 ppm
- Iron (Fe): 1,876 +/- 69 ppm
- Cobalt (Co): 3,591 +/- 75 ppm
- Copper (Cu): 287 +/- 18 ppm
- Zinc (Zn): 8,464 +/- 102 ppm
- Tin (Sn): 291 +/- 9 ppm
- Antimony (Sb): 126 +/- 9 ppm
- Barium (Ba): 89 +/- 22 ppm
- Platinum (Pt): 308 +/- 54 ppm
Reading #2) focus on plain white area
60-second reading
- Lead (Pb): 40,800 +/- 400 ppm
- Cadmium (Cd): non-detect
- Mercury (Hg): 31 +/- 12 ppm
- Bromine (Br): non-detect
- Chromium (Cr): non-detect
- Iron (Fe): 1,850 +/- 70 ppm
- Copper (Cu): 223 +/- 16 ppm
- Zinc (Zn): 90 +/- 9 ppm
- Tin (Sn): 8 +/- 5 ppm
- Barium (Ba): 40 +/- 19 ppm
- Platinum (Pt): 266 +/- 46 ppm
Reading #3) focus on red flower
60-second reading
- Lead (Pb): 51,500 +/- 500 ppm
- Cadmium (Cd): non-detect
- Mercury (Hg): non-detect
- Bromine (Br): non-detect
- Chromium (Cr): 1,140 +/- 114 ppm
- Manganese (Mn): 1,086 +/- 81 ppm
- Iron (Fe): 3,572 +/- 90 ppm
- Cobalt (Co): 2,621 +/- 65 ppm
- Copper (Cu): 309 +/- 18 ppm
- Zinc (Zn): 2,228 +/- 38 ppm
- Antimony (Sb): 17 +/- 8 ppm
- Barium (Ba): 68 +/- 20 ppm
- Platinum (Pt): 210 +/- 48 ppm
All tests on each component are repeated multiple times (using a freshly calibrated XRF instrument) to confirm the levels of toxicants found. XRF test results are accurate, replicable and science-based.

Thanks for reading. Thank you for sharing my posts. As always, please let me know if you have any questions and I will do my best to answer them personally as soon as I have a moment (which may not be right away – but I will try!)
