Extra information:
Uranium glass is a distinctive type of decorative glass coloured with small amounts of uranium oxide, producing characteristic yellow to green hues. First developed in the early 19th century, it became especially popular during the Victorian period for tableware and ornamental objects. When exposed to ultraviolet light, uranium glass fluoresces a vivid green, a feature that makes it easily recognisable today. Production centres included Britain, Europe, and the United States, where it was used for both pressed and blown glass items. Despite containing uranium, the levels are
typically very low and considered safe for handling. Its popularity declined during the mid-20th century as uranium became a regulated material. Surviving fragments are valued for their striking colour and unique optical properties, offering a glimpse into both decorative trends and historical glassmaking techniques.
