History of Uranium Glass

Uranium glass, also known as Vaseline glass, has a rich and fascinating history that spans over two centuries. The use of uranium in glassmaking can be traced back to the early 19th century, with its popularity reaching its peak during the late Victorian era and the early 20th century. The incorporation of uranium oxide into glass compositions was initially motivated by the desire to achieve vibrant and striking colors in glassware.

During the 1830s, glassmakers began experimenting with uranium oxide as a colorant, leading to the creation of glass pieces with a distinct yellow or greenish tint. This unique characteristic set uranium glass apart from other types of glass and quickly captured the attention of consumers and collectors alike. The vivid hues and the ability to emit a soft fluorescent glow under ultraviolet light made uranium glass a highly desirable and sought-after commodity.
