Uranium glass glassware

Vaseline glass, like the candlestick holder shown here, is a term for the transparent yellow to yellow-green glass that owes its color to its uranium content.

Uranium glass is glass that has had uranium added to it before melting to create colours. The uranium was added for the fluorescent effect it created. It soon became incredibly popular and started to be manufactured across Europe and North America. Most uranium glass is decorative, tableware or household items, with many pieces looking like carnival glass. Uranium glass bowls are particularly popular.

It became popular in the U. According to Michigan State University , the use of uranium was deregulated in , and production of uranium glass picked up again—except this time, only depleted uranium was used. This is when uranium glass reached the height of its popularity in the United States between and , with more than 4 million pieces of decorative uranium produced, according to Oak Ridge Associated Universities' Museum of Radiation and Radioactivity. Today, uranium is still used as a colorant in some countries, but glassmakers in the United States stopped using it in the s, when there were more easily accessible materials available. Glassmakers can achieve the look of uranium glass using other neon green colorants, but they don't react to black light the way the real thing does.

The Baccarat glassworks in France created an opaque green uranium glass which they named chrysoprase from its similarity to that green form of chalcedony.

Uranium glass is glass which has had uranium , usually in oxide diuranate form, added to a glass mix before melting for colouration. First identified in by German chemist Martin Heinrich Klaproth , uranium was soon being added to decorative glass for its fluorescent effect. Uranium glass was once made into tableware and household items, but fell out of widespread use when the availability of uranium to most industries was sharply curtailed during the Cold War in the s to s. Most such objects are now considered antiques or retro-era collectibles, although there has been a minor revival in art glassware. Otherwise, modern uranium glass is now mainly limited to small objects like beads or marbles as scientific or decorative novelties. The normal colour of uranium glass ranges from yellow to green depending on the oxidation state and concentration of the metal ions, although this may be altered by the addition of other elements as glass colorants.

Back to Glass Encyclopedia Home. Uranium glass is a term used to describe any glassware that glows green under UV light. It is made by adding small amounts of uranium oxide to the glass mixture, usually the purpose is to give a strong green or yellow colour. Vaseline glass is a type of uranium glassware that has a pale yellow green colour similar to that of petroleum jelly, often with opalescent white sections. The two terms "vaseline" and "uranium" are often used to describe the same type of glass, but to be clear, while most vaseline glass has uranium content, there is a huge amount of uranium glass, of various shades of green and yellow, even blue, cream, and white, that does not fit the description of "vaseline". Uranium glass can be detected with a geiger counter, or an ultraviolet UV light. The fact that uranium glass glows bright green under UV light, has led to uranium glass becoming popular with collectors. An Italian Murano uranium green and red glass bull sculpture.

During the Depression years, more iron oxide was added to the mixture to match popular preferences for a greener glass. The brightness of the colour will depend on the uranium content, but if glass glows under UV, it is unmistakably uranium glass. Glossary of glass art terms Glass recycling. Chemically processed uranium of the sort we are considering here consists of the following radionuclides: U, Th, Pam, U, U and Th The ratio between the effective dose equivalent rate and dose rates vary with distance because the further away from the source, the greater the area of skin that was exposed. He called the yellowish-green uranium glass Annagruen and the yellow Annagelb. Prior to World War II, natural uranium was used, but when Vaseline glass production resumed in , the switch was made to depleted uranium DU.

Vaseline glass, like the candlestick holder shown here, is a term for the transparent yellow to yellow-green glass that owes its color to its uranium content.

That being said, while your mind might be quick to jump to nuclear power plant disasters when you hear "uranium," the naturally occurring mineral is in just about everything—soil, rocks, air, water, according to the Centers for Disease Control's Agency for Toxic Substances and Disease Registry. Despite this, it is recommended that you avoid eating or drinking out of uranium glass objects, as you can end up ingesting small fragments of radioactive material. Uranium glass became popular in the midth century, with its period of greatest popularity being from the s to the s. Conversely, "Depression glass" is a general description for any piece of glassware manufactured during the Great Depression regardless of appearance or formula. After estimating the effective dose equivalents for a variety of potential exposure pathways, NUREG concluded that the highest doses would be to the personnel involved in the transportation of the glassware from a manufacturer to a truck distribution center. Retrieved 9 July Uranium was first used to color glass in the s and it has continued to be used for this purpose with the exception of a fifteen year or so period beginning in World War II.
