I make jewelry by weaving a frame from copper wire for a gemstone, then making copper coils or spirals, etc for further decoration. Even 'on the roll', the copper wire smells bad - and the smell increases as I work with the wire. The smell also clings to my hands, and I have to wash it off. I read about the chemistry that is created when copper touches skin. But the problem is, copper jewelry that has been hanging, without being worn, has begun to smell even worse - to the point that I can't even consider hanging it around my neck. Can you give me a reason for this odor (not a chemical reaction after touching my skin), and hopefully a remedy for it? I would hate to imagine what other sensitive customers would think after having one of my jewelry pieces for a few months. Thanks for helping.
