Uranium glassis glass which has had uranium, usually in oxide diurinate form, added to a glass mix before melting for coloration
The normal colour of uranium glass ranges from yellow to green depending on the oxidation state and concentration of the metal ions, although this may be altered by the addition of other elements as glass colorants. Uranium glass also flouresces bright green under ultraviolet light and can register above background radiation on a sufficiently sensitive Geiger Counter, although most pieces of uranium glass are considered to be harmless and only negligibly radioactive.
