When I traded in a batch of scrap silver, I got some deox for
casting and really like it very very much.
I am using a centrifuge for casting and everything has come out just
fine. Yes, I have soldered on it with no problems. The best part is
the fact that it does not seem to tarnish.
It is not brittle, and seems to behave the same as sterling. I made
a ring which I enlarged by hammering it against my mandrel. Again, I
had no problems–no cracks, no signs of it being brittle.
The only change I made was to let the flask cool for 20 minutes
after casting before plunging into the bucket of water. Also, I let
it cool down after soldering before quenching it in the pickle.
