Posted By: <b>Darren</b><p>What's the chemical composition of gold borders of T205? I seem to recall that it's part copper and my gas chromatograph is on the fritz again.

Posted By: <b>Shoppincher</b><p>I do think it has some copper because one of my t205's has a greenish border. That happens when copper rusts.
