The allure of a neon light. No, we are not talking about those red and blue open signs that every business seems required to have these days. We are talking Times Square. Las Vegas. Old movie marquee signs. Maybe the glimpse of a sign while driving down a dark and lonely road that says—here there are people.
Art is what a neon sign is when done with skill and imagination. Take a glass tube, bend it, shape it, fill it with purified gas, put an electrode at each of the ends and seal. Now throw the switch to electrify.
A true neon light will glow reddish-orange. Most signs aren’t made from neon but use helium, argon, mercury, carbon dioxide and other gases. Colors can be produced by a coating applied to the glass. But we call all of them neon lights.
Congrats to Razor's Wife and razor1965 on the FTF!
