Red gold alloys


#1

Lest we scare off a lot of people from red golds, I’d like to
add a little hope. I use the 75/25 Au/Cu alloy on a regular
basis. I like the color. On some occasions I have found some
cracking during rolling. Usually it is not a real problem.
Sometimes I will remelt and roll again. I haven’t used an alcohol
quench but in very rare instances. Usually just water or pickle.
The times that I have problems with red golds are in castings.
Often I’ll get extremely brittle and crackly metal.

Yes! Let’s hear it for red! I love the red golds too. Especially
because I can deplete the copper from the surface and get a
gold-rich look. If there’s any silver in the mix I don’t get this
so well.

Hey Brian, Happy New Year! I love rose golds too and don’t have
many problems w/ them. I’m using a 14k rose from AAA in Portland
Or. andf I’m fairly sure it’s got Ag in it. I’ve been depletion
gilding it fro some time and it’s gourgeuos!

Whether casting, rolling, drawing etc., rose golds don’t seem to
pose much of a problem in my experience, at least 14k.

Hi to Ruth.
