Items generating “Negative Ions” are no strangers to this channel. In fact, my first proper video was on one of them! Today we take a closer look at another pendant but this one is pretty special!
Unlike the old pendant, this one is made out of green glass which also glows under black light and is radioactive so my first assumption was that it must be uranium glass.
Uranium glass (aka vaseline glass) was produced mainly during the age of atomic madness however because of the nuclear weapons, people got scared of radiation and as a result, they stopped buying products containing uranium. Today, Uranium glass can be mainly found in antique shops but also in the Czech Republic because it is one of the very few countries producing Uranium glass!
Anyhow, back to the pendant. My first guess was that it was made out of Uranium glass but just to be sure, I did gamma spectroscopy of it. To my surprise, gamma spectroscopy revealed that the pendant did not contain uranium but Thorium meaning that this Thorium glass! When compared to Uranium glass, Thorium glass looks a little bit darker and it doesn’t glow so brightly under black light. It is also much more radioactive (U-Glass X CPM, Th-Glass 3 000 CPM)
After making a video on my first negatrive ion pendant, many people pointed out to me that the authenticity card is also radioactive but sadly I could not detect anything. Who knows, maybe they are running out of Thorium?
