Uraline is a type of glass containing uranium, usually in the form of diuranate, which gives it a characteristic yellow to green hue and green fluorescence under ultraviolet light.
Rest assured, Uraline emits slightly more radioactivity than natural uranium, but is generally considered harmless.
It has been used since antiquity to color glass, but was most popular between 1880 and 1920 for decorative objects such as crockery and trinkets.
Production declined with the confiscation of uranium during the Second World War.
Today, ouraline is prized by collectors and used for decorative objects.
