Uranium glass contains uranium oxide, which gives the glass a yellow or yellow-green tint, and causes it to glow under a UV black light. Uranium glass became popular in the mid-19th century, with its period of greatest popularity being from the 1880s to the 1920s. The uranium glass used to make this ornament comes from depleted uranium which has minimal radioactivity and is harmless.
