Uranium glass is a colored glass, made by adding a small amount of uranium into a base glass.
It has a typical color tone, i.e., either light yellow or light green. The glass has, however, a unique and beautiful shining, due to the fluorescent effect of uranium contained in the glass. For instance, the specific shining makes it possible to identify easily this type of glass pieces exhibited among the other ordinary colored glasses. Since the middle of the last century, people in Europe as well as the US very much cherished the uranium glass. Indeed, it was then the most popular colored glass in these countries.
