Uranium glass, also known as Vaseline glass due to its distinctive yellow-green hue, is a fascinating type of glassware that contains trace amounts of uranium oxide. Its vibrant color and unique glow under UV light have made it a popular collectible among enthusiasts and historians alike. But many wonder: which company was responsible for manufacturing uranium glass? In this comprehensive guide, we will explore the origins of uranium glass, the key companies involved in its production, and the historical context that shaped its development.
Understanding Uranium Glass
Uranium glass is a type of colored glass that contains a small amount of uranium oxide, typically between 2% and 25%. The addition of uranium gives the glass its characteristic vibrant yellow-green coloration, especially when viewed under normal lighting conditions. When exposed to ultraviolet (UV) light, uranium glass fluoresces with a bright green glow, which has contributed to its nickname "Vaseline glass."
Its production dates back to the late 19th century, coinciding with the discovery and increased utilization of uranium during the early 20th century. While uranium was primarily used for its radioactive properties in nuclear applications, the glass industry found a use for small quantities of uranium oxide as a coloring agent.
Historical Development of Uranium Glass
The earliest known production of uranium glass dates to the late 1800s, when glassmakers discovered that adding uranium oxide yielded a striking yellow-green hue. The most prominent period of uranium glass production was from the early 1900s through the mid-20th century, especially during the Art Deco era, which embraced bold and luminous designs.
During World War II and the subsequent Cold War era, the production of uranium glass declined due to fears related to radioactivity and the shift in focus toward nuclear technology. Nevertheless, vintage uranium glass remains highly collectible today, appreciated both for its aesthetic qualities and its historical significance.
Key Companies Responsible for Making Uranium Glass
Several glass manufacturers and companies contributed to the proliferation of uranium glass during its peak production years. Some of the most notable include:
- Fenton Art Glass Company
- Westmoreland Glass Company
- Kaiser Glass (Royal China and Imperial Glass)
- Libbey Owens Ford (LOF) Glass
- Fostoria Glass Company
- Hawkes & Co.
Let's explore these companies and their roles in uranium glass manufacturing in more detail.

Imperial Glass, based in Ohio, was particularly known for its art glass and luminous Vaseline glass during the 1930s and 1940s. Their pieces often featured elegant designs, with some marked or labeled for identification.
Kaiser’s contributions helped expand the variety and reach of uranium glass products nationwide.
Libbey Owens Ford (LOF) Glass
Libbey Owens Ford, a major glass manufacturer, ventured into uranium glass production during the early 20th century. While primarily known for industrial and automotive glass, they also produced decorative uranium glass items. Their pieces are sometimes distinguished by their quality and consistency, reflecting their advanced manufacturing processes.
Fostoria Glass Company
Based in Ohio, Fostoria Glass Company was a leading producer of fine glassware, including uranium glass in the 1930s and 1940s. Their line included elegant tableware, vases, and other decorative items. Fostoria's uranium glass is appreciated today for its craftsmanship and historical significance, often featuring detailed patterns and shapes.
Hawkes & Co.

Other Notable Manufacturers
Beyond the major companies listed above, several smaller manufacturers and regional producers also contributed to the uranium glass movement. These include:
- Hocking Glass Company
- Diamond Glass Company
- Northwood Glass Company
- Bailey, Banks & Biddle
Many of these manufacturers produced limited runs or regional pieces that are now prized by collectors for their rarity and historical value.
How to Identify Authentic Uranium Glass
Identifying authentic uranium glass involves several key indicators:
- Color: Typically a yellow-green or chartreuse hue, often vivid under normal lighting.
- Fluorescence: When exposed to UV light, genuine uranium glass fluoresces bright green.
- Labeling and Marks: Some manufacturers marked their items with logos or labels, though many are unmarked.
- Weight: Uranium glass tends to be heavier than regular glass due to uranium content.
Always purchase from reputable sources or collectors to ensure authenticity, and consider testing with a UV flashlight for confirmation.
The Legacy of Uranium Glass
Although production declined after the mid-20th century, uranium glass remains a prominent collectible. Its unique glow, historical significance, and aesthetic appeal continue to attract enthusiasts worldwide. Museums and private collectors cherish vintage uranium glass pieces, which serve as tangible links to the technological and artistic innovations of the early 20th century.
Modern reproductions exist, but authentic vintage pieces from companies like Fenton, Westmoreland, and Imperial are highly valued for their craftsmanship and rarity.
Conclusion
In summary, multiple companies played a role in manufacturing uranium glass throughout the first half of the 20th century. Among the most notable are the Fenton Art Glass Company, Westmoreland Glass Company, Imperial Glass, and Hawkes & Co., each contributing uniquely to the development and proliferation of this luminous material.
