I am looking for the melt and flow temps of 18k green gold when it is
composed only of silver and gold. Have only been able to find the
info when it has copper as well, but that doesn't help me.
Margaret- Do you alloy your own green gold?
If not then contact your supplier for the alloy ingrediaents and
melting temperatures. Hoover & Strong have several green gold alloys
and they're quite professional in supplying all the data.
If it is truly only gold and silver its solidus is 1023 C (1873 F)
and the liquidus looks to be about 40 C (104 F) higher
