Can’t recall which list this was on, rockhounds or R&F, but am
trying to find info on a technique of jewelry casting. The
discussion was about that new clay jewelry metal, that can be
molded then cast; which brought up something called, “powder
casting?” It’s used in industry. Powdered metal is put into a
mold. Mold is heated, metal melts, hardens, and voila! another
self-lubricating gear.
I saw (and lost) a newspaper article about this, as a
technique for creating jewelry. Said this method of
jewelry-making goes back to the time of the ancient Greeks and
Romans. The article didn’t list any bibliographical info.
What I want is:
What is proper name given to this method?
Are there any books, manuals, web sites…etc. that more fully
explain how it’s done.
Also, given that the ancients were [supposedly] low-tech, is
there an economical way of " powdering" metal. Or can gold,
silver, sterling, etc. be bought in this form?
