TC> Very interesting, Thanks for your input John, I was wondering

G’day Isaac; there is little difference in electroforming and
electroplating; in electroforming one simply continues plating
whatever metal one is using until the plate has become
sufficiently thick for what you need.

The reason that Rio’s solution is expensive is partly due to the
fact that silver based chemicals aren’t cheap, though I suspect
suppliers might load up the price a bit. To electroform with
silver I use a cyanide solution bath and use a piece of pure
silver as a positive electrode, and warm the bath a little. I’m
afraid I don’t know of any good replacement for cyanide.

You will get a plate from silver nitrate, but it will be as
granular as when you use copper sulphate, though you could try an
extremely low electric current to see if that improves grain
size. You would do best by texturing the article after it has
been formed by other methods. I’m afraid that cyanide plating or
forming baths seem to be the best electrolytes. Sorry , but
that’s all I can offer.
