Hi again
is there anything i can add to the silver to clean up the silver when
i melt it i normaly put i pinch of borax in with my scrap. i used to
work in a foundry and when we refilled the casting pots we put in
some power and when the molten metal was mixed all the scum used to
come to the top which would then be scooped off which would leave the
metal clean and gas free so the castings would be perfect, the thing
is i can remember what the stuff was called, can anyone help, also
apart from borax what else can be used when melting scrap silver. i
saw something somewhere talking about salt peter/saltpetre (dont know
which is correct ) in melting metal. and im sorry to keep goin on but
can anyone tell me what the use for argoflux is.
many many thanks
jason
