I’m new to this forum and this is my first mail.I make jewells of
sterling silver and I would like to ask something that may seems
very simple to you but because I 'm from Greece the terminology you
and is common between you is very unfamiliar to me.So to my
question: what exactly are you doing with your flasks after casting?
What I mean is that I do the following:
take the flask from casting machine (mine is centrifugal)
immidiatelly put the flask in a barrel of water where flask
separates from the tree+a lot of investment
we put tree+a lot of investment in a water machine where we
we heat the tree with a torch and then we put it in
water+sulfiric acid (not boiling)
we repeat step 5 untill the tree becomes paper white After that we
cut off tree and compine the jewell parts then using 3 different
brushes we “smooth” the pieces and then we heat the pieces again with
the torch and put them again in sulfiric acid.The last step 3D is to
put them in a U shape polishing macine.
So I would like to ask is there a way to avoid the “mists” of
sulfiric acid but with the same result? Are there other methods to do
the same things? Are there any other order for doing the same things?
Thanks in advance
