Just wondering if this has happened to anyone else? I bought a
piece of Argentium silver and made a ring (using medium solder) and
got loads of purple patches which I found very difficult to remove.
Also, after leaving the piece out for a few days on my bench, it
turned close to black! Am I doing something wrong? Please help!
If I may hazard a guess it sounds like your Argentium Silver (AS)
hasn’t been sufficiently heat treated to “activate” it’s tarnish
resistance. It’s not an uncommon occurrence. The good news is that
it’s dead easy to solve: just heat the AS nicely and the problem goes
If you check the Orchid archives at
and search for “activate” or “activation” you’ll find a number of AS
specific threads related to just this topic.
If you’re interested in more info on this I talk about it a fair
amount on my “Working with Argentium Silver” blog (follow the "blog"
link at my site). Again, search for “activate” or “activation” and
you’ll get a couple of good hits. Search for “tarnish resistance” and
you’ll get several more.
