What is fenton glass uranium?

Fenton glass uranium is a type of glassware that contains uranium. This type of glass is also known as Vaseline glass because of its yellow-green color, which resembles vaseline. The use of uranium in glassmaking began around 1830 and became popular in the mid-19th century.

Fenton Glass, a US-based glass company known for its art glass and collectibles, produced uranium glassware from the 1920s to the 1940s. The company used uranium oxide to create a bright and distinctive yellow-green color in their glassware. The glass also possesses a unique property of fluorescing under black light due to the uranium content.

Although the use of uranium in glassmaking declined after World War II due to safety concerns, antique Fenton glass uranium pieces remain highly collectible today. However, it is important to note that the uranium content in these pieces is generally considered safe unless ingested in large amounts, which is unlikely to occur in normal use or handling.
