Thanks for all the great advice both offline and online. With all
the ideas I think I'll try a little experiment, although it won't be
scientific. The cripple creek turquoise I work with comes in both
blue and green with the blue having more copper and the green having
more iron. I'll polish 3 pieces of flat sterling. In three
separate bags I'll place a piece of silver and in two of the bags a
piece of turquoise. One green; one blue. I'll place them in the same
drawer as I keep all my finished pieces.
If I don't get the yellow tarnish in one of 3 the bags I'll heat and
pickle the silver and polish again. I'll use the southwestern
screen method of heating from underneath. Then see if I get any
Of course the best solution would be to use paper job envelopes. The
situation is one of my clients prefers the pieces in individual bags
with my wholesale price on them. That way when we do our transaction
she can see the price of each piece and not have to trace it back to
the invoice. It also makes in easier for her to price them as we do
most of our transactions at shows and she is greeting and waiting on
customers at the same time.
I'll post my results when and if I get them and will also check out
the antitarnish paper recommended to me.
