Item #219

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.

  • Size is around ⅞ – 1” diameter.
  • These are vintage, so some dents, small chips, and manufacturing imperfections can be expected.
  • Slightly radioactive, but they're harmless.
  • Makes a great uranium sample if you're collecting the elements.
  • Comes in an acrylic storage box.

Interesting and awesome

Uranium in glass, very interesting! Even when I showed it to my wife under UV light, she was quick to ask "Is it safe?". I assured her it was safe - "Just don't eat it!" I replied. Just a cool item to own and show off now and then.


Really a neat item! Just as described and arrived quickly
