Channel Page: http://www.youtube.com/user/mopatin/ Twitter: https://twitter.com/mopatin Google + : http://www.google.com/+mopatin 10, 20 and 50 cent of euro coins are made of nordic gold, and alloy made of: 89% copper, 5% aluminium, 5% zinc, and 1% tin. I melt two of these 10 cent coins with an oxi-butane torch. The problem is oxidation. I will try to solve the problem with borax and or boric acid.
