Lead glass's primary contemporary use is in the construction of Television s and Monitor s. In a standard Cathode Ray Tube , high-energy Electrons are fired at Phosphor s painted on the inside of the tube. This impact creates the visible Light the monitor or tv screen produces; it also produces X-ray s. The lead in the glass acts as a barrier to this unwanted Radiation . Unfortunately, the amount of lead glass finding its way into Landfill s as a result of discarded electronic equipment may be more of a Hazard than the radiation it is designed to block. Lead glass has been used in aircraft used in testing Nuclear Weapons for this radiation blocking effect. Cut lead glass, also known as lead crystal, is used in fine tableware, particularly Wine glasses and Decanter s. It was unknown until a few decades ago that Alcohol stored in a decanter was capable of Leaching the lead from the glass and contaminating the contents. While fine wine glasses are still made of lead glass, use of lead glass containers for the storage of alcoholic beverages of any sort is discouraged. In addition, Lead acetate has a sligtly sweet taste, leading people to belive that wine is best served in leaded glass. SEE ALSO |
