Beautiful Piece!! _______________________________ First identified in 1789 by German chemist Martin Heinrich Klaproth, uranium was soon being added to decorative glass for its fluorescent effect. James Powell's Whitefriars Glass company in London, England, was one of the first to market the glowing glass, but other manufacturers soon realized its sales potential and uranium glass was produced across Europe and later in Ohio. Uranium glass was 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 1940s The normal color of uranium glass ranges from yellow to green depending on the oxidation state and concentration of the metal ions Vaseline glass The most common color of uranium glass is pale yellowish-green, which in the 1930s led to the nickname "Vaseline glass", based on a perceived resemblance to the appearance of Vaseline-brand petroleum jelly as formulated at that time. Specialized collectors still define Vaseline glass as transparent or semi-transparent uranium glass in this specific color. Vaseline glass is sometimes used as a synonym for any uranium glass, especially in the United States, but this usage is frowned upon, since Vaseline-brand petroleum jelly was only yellow, not other colors. The term is sometimes applied to other types of glass based on certain aspects of their superficial appearance in normal light, regardless of actual uranium content which requires a black light test to verify the characteristic green fluorescence. Uranium glass became popular in the mid-19th century, with its period of greatest popularity being from the 1880s to the 1920s. The first major producer of items made of uranium glass is commonly recognized as Austrian Franz Xaver Riedel, who named the yellow (German: Gelb) and yellow-green (German: Gelb-Grün) varieties of the glass "annagelb" and "annagrün", respectively, in honor of his daughter Anna Maria. Riedel was a prolific blower of uranium glass in Unter-Polaun (today Dolni Polubny), Bohemia from 1830 to 1848. By the 1840s, many other European glass works began to produce uranium glass items and developed new varieties of uranium glass. The Baccarat glass works in France created an opaque green uranium glass which they named chrysoprase from its similarity to that green form of chalcedony.

At the end of the 19th century, glass makers discovered that uranium glass with certain mineral additions could be tempered at high temperatures, inducing varying degrees of micro-crystallization. This produced a range of increasingly opaque glasses from the traditional transparent yellow or yellow-green to an opaque white. During the Depression years, more iron oxide was added to the mixture to match popular preferences for a greener glass. This material, technically a glass-ceramic, acquired the name "Vaseline glass" because of its supposedly similar appearance to petroleum jelly. a few manufacturers continue the Vaseline glass tradition: Fenton Glass, Mosser Glass, Gibson Glass and Jack Loranger. U.S. production of uranium glasses ceased in the middle years of World War II because of the government's confiscation of uranium supplies for the Manhattan Project from 1942 to 1958. Uranium glass can register above background radiation on a sufficiently sensitive Geiger counter, although most pieces of uranium glass are considered to be harmless and only negligibly radioactive. .
