G: Ok I see the results which to me are puzzling. I am certainly NOT a metallurgist but I would think that those tested combinations of silver and copper would yield a very durable metal that of course would wear well. As we know this was not the case with TK rings and they wore rapidly as anyone who has examined them can attest. I of course accept these results obtained by Pepera but they IMO in no way account for the wear seen in TK rings. Again; I have a TK copy made by Hapur of a known metal content which is .925(Sterling) and after 10 + years of constant use shows virtually no wear.
Here is the composition of Sterling from the Internet: "Sterling silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper. The sterling silver standard has a minimum fineness of 925."
I'd really be interested in some sort of explanation regarding the vast differences in apparent wear!
