Uranium glass, often referred to as “Vaseline glass” due to its resemblance to the petroleum jelly’s color, is a type of glass that contains uranium dioxide, which gives it a distinctive green or yellow glow under ultraviolet light. This unique characteristic has made uranium glass a subject of fascination for collectors and historians alike. But what is uranium glass worth? The value of uranium glass can vary widely depending on several factors, including its age, rarity, condition, and the demand among collectors.
Historical Context and Production
Uranium glass was first produced in the early 19th century, with its popularity peaking during the late 19th and early 20th centuries. The addition of uranium dioxide to glass not only provided a unique color but also enhanced the glass’s durability. However, the use of uranium in glass production declined after World War II due to concerns over radiation, although it was never entirely discontinued.
Factors Influencing Value
-
Age and Rarity: Older pieces of uranium glass, especially those from the 19th century, are generally more valuable. The rarity of certain designs or colors can also significantly increase the worth of a piece.
-
Condition: As with any collectible, the condition of uranium glass plays a crucial role in determining its value. Pieces that are free from chips, cracks, or repairs are more desirable.
-
Design and Maker: The design and the manufacturer of the glass can also affect its value. Pieces from well-known glassmakers or those with intricate designs are often more sought after.
-
Demand: The current demand among collectors can greatly influence the price of uranium glass. Trends in collecting can shift, affecting the desirability and thus the value of certain pieces.
Collecting Uranium Glass
Collecting uranium glass can be a rewarding hobby, offering a glimpse into the past and the opportunity to own a piece of history. However, potential collectors should be aware of the following:
-
Radiation Concerns: While the levels of radiation in uranium glass are generally considered safe, some collectors prefer to handle these pieces with care, using gloves or limiting exposure.
-
Authentication: Due to the value of some uranium glass pieces, it’s important to ensure authenticity. This can often be done through expert appraisal or by using a black light to confirm the presence of uranium.
-
Market Trends: Keeping an eye on market trends can help collectors make informed decisions about when to buy or sell.
Conclusion
Uranium glass is more than just a collectible; it’s a piece of history that glows with the stories of the past. Its value is not just monetary but also lies in its unique beauty and the craftsmanship of its creators. Whether you’re a seasoned collector or a curious newcomer, the world of uranium glass offers a fascinating journey into the art and science of glassmaking.

Q: How can I tell if a piece of glass contains uranium? A: The most common method is to use a black light. Uranium glass will glow a bright green under ultraviolet light due to the presence of uranium dioxide.
Q: Are all green or yellow glasses uranium glass? A: Not necessarily. While uranium glass often has a green or yellow hue, not all green or yellow glass contains uranium. The definitive test is to check for fluorescence under a black light.
Q: Can uranium glass be used for drinking or eating? A: While uranium glass was historically used for tableware, modern collectors generally do not recommend using it for food or drink due to the potential, albeit minimal, health risks associated with uranium.
