Questions on making Copper-Silver-Zinc alloy

Casting alloy | copper | silver | zinc

Hi Everybody,

My first post here, a question:

I'd like to make an alloy of 80% Copper, 10% Silver and 10% Zinc, to be poured into lost-wax molds (plaster/sand) on a small scale (eg. 10oz total). Copper and silver have reasonably close melting points (Cu 1981F and Ag 1762F), but Zn has a boiling point of 1664F, meaning it could boil off before the other two melted.
