WHAT IS IT
Uranium glass is a type of glass which contains a small amount of uranium—usually about 2% by weight. Uranium was once commonly added to glass for yellow or green coloration, but became less popular after more research into radioactivity and uranium’s uses caused the element’s availability to become more stricly regulated. While the glass sphere included is very slightly radioactive, it is harmless and safe to touch.
