You may then coat it with a thin layer of transparent nail polish or use a pray lacquer (used for isolation in electronics) to protect your key chain. Good luck!

This means that when copper is left out in the open the oxygen in the air causes a chemical reaction which in turn causes a patina to develop on the surface of the copper. A patina is the blue-green colouration that you are seeing on the copper. It is unavoidable, but it does create a very beautiful effect. The blue hue of the patina plays off of the orange hue of the copper. Blue and orange are complimentary colours, meaning they work well together and bring out the best in one another.<a href="http://www.resumeminers.com/Resume/Free-Resume.htm"> scoobycat72</a> Copper, when exposed, becomes oxidized.

For the short term, I would suggest holding it with a piece of cloth to slow the rate of tarnishing, or perhaps a eyeglasses cleaning cloth.<a href="http://www.medicalsupplyservices.com/diabetes-medical-supply.htm"> greekgirlie1122</a> (copied from your previous question)
