When tested with an XRF instrument the Grace’s Teaware saucer pictured here (with purple flowers with green leaves – additional photos below) had the following readings:
Green Leaves:
- Lead (Pb): 30,000 +/- 800 ppm
- Chromium (Cr): 3,060 +/- 170 ppm
- Antimony (Sb): 157 +/- 29 ppm
- Tin (Sn): 84 +/- 23 ppm
- Zinc (Zn): 11,100 +/- 400 ppm
- Iron (Fe): 1,935 +/- 231 ppm
- Vanadium (V): 75 +/- 35 ppm
- Titanium (Ti): 333 +/- 64 ppm
- Zirconium (Zr): 1,884 +/- 74 ppm
- Platinum (Pt): 361 +/-147 ppm
- Cobalt (Co): 986 +/- 140 ppm
Purple Flowers:
- Lead (Pb): 19,000 +/- 500 ppm
- Tin (Sn): 356 +/- 27 ppm
- Zinc (Zn): 11,000 +/- 300 ppm
- Iron (Fe): 481 +/- 140 ppm
- Vanadium (V): 127 +/- 37 ppm
- Titanium (Ti): 609 +/- 75 ppm
- Silver (Ag): 26 +/- 7 ppm
- Zirconium (Zr): 1,906 +/- 66 ppm
- Platinum (Pt): 305 +/- 121 ppm
- Cobalt (Co): 2,506 +/- 185 ppm
Each area was tested for a minimum of 60 seconds (one full minute) using an XRF instrument testing in “Consumer Goods” mode. All test results reported on this blog are science-based and replicable. Metals not listed in the reading sets above were not detected by the XRF in “Consumer Goods” mode.

I have a Grace’s teaware with a striped vintage style set with blue design on the inside and gold scalloping along the edges on the outside. I have matching cups and plates, have you tested that design?

I have a Grace Teaware Fine Poecelain storage container with decorative flowers on the outside, I can send you a picture, have you tested those by chance?
