There’s a kind of novelty in owning glass that glows (think of all the neat party tricks). There are several types of glass that were made with uranium in them. If it’s a green or canary yellow color, expose the piece to a black (or another kind of ultraviolet) light. Yes, the same uranium used for bombs and nuclear power reactors. The fluorescence occurs because there is uranium, used extensively as a colourant between the early 19 th and late 20 th century, in the glass.
