When tested with an XRF instrument the 2017 Spectr Design “Coffee before Talkie” ceramic mug (pictured here) had the following readings:
Focus on the blue of the mug:
60-second test
- Lead (Pb): 24 +/- 10 ppm
- Barium (Ba): 68 +/- 33 ppm
- Zirconium (Zr): 3,170 +/- 81 ppm
- Platinum (Pt): 252 +/- 99 ppm
- Zinc (Zn): 31,500 +/-700 ppm
- Copper (Cu): 72 +/- 33 ppm
- Iron (Fe): 2,212 +/- 182 ppm
- Titanium (Ti): 15,600 +/- 900 ppm
Focuse on the black printed words:
60-second test
- Lead (Pb): 59 +/- 12 ppm
- Cadmium (Cd): 11 +/- 5 ppm
- Barium (Ba): 101 +/- 31 ppm
- Chromium (Cr): 6,406 +/- 402 ppm
- Tin (Sn): 25 +/- 11 ppm
- Zinc (Zn): 15,700 +/- 400 ppm
- Copper (Cu): 129 +/- 35 ppm
- Nickel (Ni): 650 +/- 85 ppm
- Cobalt (Co): 5,840 +/- 259 ppm
- Iron (Fe): 25,300 +/- 700 ppm
- Vanadium (V): 721 +/- 237 ppm
- Titanium (Ti): 9,876 +/- 690 ppm
Focus on the white of the mug (which is also the interior glaze):
60-second test
- Lead (Pb): 31 +/- 11 ppm
- Barium (Ba): 157 +/- 33 ppm
- Zirconium (Zr): 1,715 +/- 46 ppm

- Zinc (Zn): 32,600 +/- 700 ppm
- Iron (Fe): 2,418 +/- 186 ppm
- Manganese (Mn): 586 +/- 201 ppm
- Titanium (Ti): 16,000+/- 900 ppm
Focus on the logo on the bottom of the mug:
30-second test
- Zirconium (Zr): 4,209 +/- 147 ppm
- Zinc (Zn): 31,600 +/- 1,000 ppm
- Iron (Fe): 2,100 +/- 250 ppm
- Titanium (Ti): 15,800 +/- 2,400 ppm
As always, thank you for reading and for sharing my posts. I will likely update this post soon with more information, however in the meantime please check out the following links if you have questions:
- The testing methodology for all tests reported on on this blog.
- A video showing you how to search the blog most efficiently, given there are over 2,700 posts and pages here.
- My documentary feature film on childhood Lead poisoning.
Please let me know if you have any questions. With 1.165 Million unique readers in 2020 alone I am not always able to answer each and every question personally, but I do try.
