Uranium glass.
- What is uranium glass?
Uranium glass, also known as Vaseline glass, is an attractive type of glass that contains uranium, which gives it a unique greenish-yellow color and an attractive fluorescent glow under ultraviolet (UV) light. This glass was mass produced from the mid-19th to early 20th centuries and remains a popular collector’s item today. - A brief history
Uranium glass has a rich history dating back to the early 19th century. It was first produced in the late 1830s by a German chemist named Martin Heinrich Klaproth, who discovered uranium oxide and began experimenting with its use in glassmaking. Glass gained popularity in the Victorian era, where it was used for decorative items such as tableware, jewelry, and decorative objects. - The science behind light
The secret to uranium glass’s distinctive luster lies in its uranium content, typically 0.1% to 2% uranium dioxide by weight. When exposed to UV light, the uranium atoms in the glass become excited and emit visible light, resulting in the characteristic bright green fluorescence. This phenomenon, known as fluorescence, is a key factor that makes uranium glass so attractive and visually appealing. - Is uranium glass safe?
A common question about uranium glass is whether it is safe to handle and use. Although it contains uranium, the level of radioactivity is generally very low and not considered harmful for casual handling or display. However, it is always wise to exercise caution, avoid using it for food or drink, and limit prolonged exposure, especially if the glass is chipped or damaged. - Collection of Uranium Glass
