Synonymous to nightlife, neon is probably among the fabulous findings by mankind. It was first discovered in 1898 by the British physical chemist Sir William Ramsay and Morris W. Travers while they were conducting one of their experiments on the principles of electrical discharge by using glass tubes. Neon is an inert gas that is colorless and odorless. Ramsay and Travers both named it neon - after the Greek word meaning "new".
It was much later in 1910 that neon signs made its' debut at the Paris Expo. It was a neon sign of two 38-foot long tubes. Georges Claude was the one who found that by filling a tube with neon gas will caused electrical discharge to occur. The tube glowed of deep red. The neon must be purified of any other gases in order for the electrical discharge to permeate it and pass through the tube. In other words, the tube has to be vacuumed of any other gasses. Purification is accomplished by the use of charcoal which, when cooled to -180 to -190 degrees Centigrade, absorbs impurities in the tube and is subsequently removed.
Now and then, neon signs have been widely used in advertising and commercial application. Neon lightings were quickly recognized in the early twentieth century, and soon other vapors besides neon were used such as Argon, Helium, Xenon and Krypton. Besides that, other color pigments can also be embedded to the glass tube's walls to produce lightings of other colors. Neon in its' natural state is harmless to human beings. Neither is it poisonous or explosive like some other gasses, which is mainly the reason why, it is widely used by in advertising.
