You told me that the only thing I really must concern myself with
is a separate set of buffing wheels.
If you go back and check that email I think you’ll find that I
recommended two things:
- separate polishing buffs, etc.
- separate fire bricks.
I think, as does ArgentiumSilver.com if you read their datasheet on
Argentium Sterling (AS), that both of these are important. IMHO, the
second even more so than the first.
If I were to take a fully polished piece in Argentium Sterling, and
put it for a few minutes in the Super Pickle would I be preventing
later oxidation from residual copper?
Personally I doubt it but it’s probably not going to hurt anything
either so why not give it a try. The question, of course, is how do
you know if it worked. This brings us to accelerated tarnish testing.
One of the little tricks I use to see how good the tarnish resistance
is on a piece of AS it to put it and a polished strip of regular
sterling silver in a steamer with a handful of fresh broccoli (cut
into flowerlets). It is important to degrease the metals first. Let
the steamer run at full boil for about 10 minutes, you should be able
to smell the broccoli. This is usually enough to turn the sterling
quite grey, longer in the steamer will darken it even further.
If your AS is still clean after this test, or has light blush of
straw colored oxide on it, then I’d say your tarnish resistance is in
pretty good shape. If the AS darkens noticeably then it’s not in such
good shape after all. I realize that this test is about as
bush-league as it gets but at least it’s something.
