I hope no one is trying to say that the silver on Petes oxidizes any faster than any other sterling silver. I don't think you are, but being a Pete thread, someone will get that idea. All sterling is of the exact same composition, so no sterling is better than another. argentium now, that's a different story. But, that would have to be stamped as such, being British (or is Ireland still a part of Britain?) anyways, argentium silver was formulated by my buddy, James Binnion, and it doesn't oxidize, and it is .925 also. But, I haven't heard of it being used in pipe production... yet. Maybe it should be, but it requires an extra step in production that would make it a tad more expensive.
