The Glow of Uranium

The eerie green fluorescence of uranium, caused by the uranyl ion added to this glass "salt dip", from the 1940s. It takes very little uranium to impart this green fluorescence, although this piece is more radioactive than most glass--but still safe to handle. Still, I wouldn't use it for food.
