Uranium Glass Ball
Uranium Glass Ball
- Radiation: 0.14 μSv/h
Uranium glass is a type of glass made with a small amount of the radioactive element with atomic number 92. This causes it to glow intensely bright green under ultraviolet light.
It was once common for glass manufacturers to add small amounts of uranium oxide, around 2% by weight, to their items to achieve yellow or green coloration. This practice became less popular after the element was strictly regulated in the US under the Atomic Energy Act of 1954.
Since UV lights are now widely accessible, interest in uranium glass has risen again and is now sought by collectors. The presence of uranium also means the glass is slightly radioactive. It is harmless to handle, but please avoid eating it.
In America, uranium is illegal to own without a license; however, an exception has been made for glassware containing uranium, according to the Nuclear Regulatory Commission.

I've got a bunch of black lights that make it light up pretty good. Very cool purchase that got here WAYYYY earlier than I expected. It was like 3 days and the shipping notification said like 2 weeks. Very pleased indeed.
