Making sterling alloy for casting

Hi,

Thanks for the replies everyone.

If I decide to try this should I do it in a single melt as suggested
for gold? Or should it be pickled to remove oxides before being
cast?

Also, where could I get a charcoal crucible?

Thanks again,
Douglas

I make my own alloying crucibles using a charcoal soldering block as
material. I simply make a depression into it using a dapping punch.
