Back in the day WinOx was the standard for oxidation effect on silver
jewelry. I used this product extensively dating from the early 1970s.
Commonly applied to "western style" jewelry, large cowboy motif
pieces with stamped and incised designs, intricate overlay patterns,
twisted rope borders, shadow boxes around cabochons, etcetera. (I am
sure John D and Sam P made a lot of similar things during that era
too, probably more than a few others on this list as well).
It gave a durable black coloration that was stable and relaible. It
did posess a decidely pungent and caustic aroma and it seemed that a
bottle of it kept forever without diminishing in strength.
Its funny, I was thinking about this product just a month ago or so
when some of my students in Milwaukee were talking about the
difficulty they had getting consistent results with liver of
sulpher. None of the students had heard of WinOx. I couldn't recall
when went off the market, I had not used it since the mid 1980s.
