Introduction (for those new to this website):
Tamara Rubin is an independent advocate for consumer goods safety. 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. Tamara uses high-precision XRF testing (a scientific method used by the U.S. Consumer Product Safety Commission) to test consumer goods for metallic toxicants, including Lead, Cadmium, Mercury, and Arsenic.
Below are the XRF readings for the vintage clear wine glass (with press lines) pictured here; 60-second reading:
- Bromine (Br): 9 +/- 3 ppm
- Zinc (Zn): 34 +/- 16 ppm
- Iron (Fe): 257 +/- 114 ppm
- Vanadium (V): 75 +/- 20 ppm
- Titanium (Ti): 63 +/- 23 ppm
- Indium (In): 21 +/- 9 ppm
Vintage glass with press-lines is not *always* Lead-free, but it is *almost always* Lead-free, and in the absence of testing a vintage glass piece with a high-precision XRF instrument, checking to see if there are press lines (as an indicator that it is *likely to be* Lead-free) is a good place to start. You can read more about that on this post – link.
XRF readings are science-based, replicable, and accurate. Each component of each piece reported on here has been tested multiple times to confirm the readings, and one full set of readings (per component) is shared here on the blog.
