Uranium glass, also known as Vaseline glass, is a type of glass that contains uranium oxide, which gives it a unique glow-in-the-dark property. This type of glass has been around for over a century and has been used in various applications, including decorative objects, jewelry, and even medical equipment. One of the most fascinating aspects of uranium glass is its range of colors, which can vary greatly depending on the type of uranium oxide used and the manufacturing process. In this article, we will explore the different colors that uranium glass can be, and what makes each one unique.
The History of Uranium Glass
Uranium glass has a rich history that dates back to the late 19th century. In the 1880s, a German glassmaker named Friedrich Eduard Schulze discovered that adding uranium oxide to glass created a unique glow-in-the-dark effect. This discovery led to the production of uranium glass, which quickly became popular for its unique properties. During the early 20th century, uranium glass was used in a variety of applications, including decorative objects, jewelry, and even medical equipment. Today, uranium glass is still used in various applications, including decorative objects, jewelry, and even art.
The Colors of Uranium Glass
Uranium glass can be found in a wide range of colors, each with its own unique properties and characteristics. Some of the most common colors of uranium glass include:
Yellow and Green
The most common colors of uranium glass are yellow and green. These colors are created by adding different amounts of uranium oxide to the glass. Yellow uranium glass typically contains a higher concentration of uranium oxide than green, which gives it a brighter, more vibrant color. Green uranium glass, on the other hand, contains a lower concentration of uranium oxide, which gives it a more muted, earthy tone.
| Color | Uranium Oxide Concentration |
|---|---|
| Yellow | Higher concentration (typically 2-5%) |
| Green | Lower concentration (typically 0.5-2%) |
Orange and Red
In addition to yellow and green, uranium glass can also be found in orange and red shades. These colors are created by adding different types of metal oxides to the glass, such as copper or iron. Orange uranium glass typically contains a higher concentration of copper oxide, while red uranium glass contains a higher concentration of iron oxide.

| Color | Metal Oxide Concentration |
|---|---|
| Orange | Copper oxide (typically 1-3%) |
| Red | Iron oxide (typically 1-3%) |
Purple and Blue
Uranium glass can also be found in purple and blue shades. These colors are created by adding different types of metal oxides to the glass, such as cobalt or manganese. Purple uranium glass typically contains a higher concentration of cobalt oxide, while blue uranium glass contains a higher concentration of manganese oxide.
| Color | Metal Oxide Concentration |
|---|---|
| Purple | Cobalt oxide (typically 1-3%) |
| Blue | Manganese oxide (typically 1-3%) |
The Science Behind Uranium Glass
Uranium glass gets its unique glow-in-the-dark property from the presence of uranium oxide. When exposed to light, the uranium oxide absorbs the energy and releases it as a longer wavelength of light, which is what gives the glass its glow-in-the-dark effect. The amount of uranium oxide present in the glass determines the intensity and duration of the glow.
The process of creating uranium glass is complex and requires a high level of precision. The glassmaker must carefully control the amount of uranium oxide added to the glass, as well as the temperature and duration of the manufacturing process. If the glass is not made correctly, it may not glow at all, or it may glow too brightly.
Conclusion
In conclusion, uranium glass is a unique and fascinating material that can be found in a wide range of colors. From yellow and green to orange and red, purple and blue, each color has its own unique properties and characteristics. The science behind uranium glass is complex and requires a high level of precision, but the end result is a material that is both beautiful and functional. Whether used in decorative objects, jewelry, or even art, uranium glass is a truly unique and captivating material.
