The alloy is simply 80% fine silver and 20% copper,
I use a higher copper ratio: 15% fine silver and 10% copper to 75%
fine gold. The color is only slightly redder, but the alloy is a bit
harder that the 20%Cu / 5%Au alloy suggested. You can easily
depletion guild this alloy by allowing an oxide to form, then
removing it in the pickle. I pre-polish the piece, but do not rouge
polish it. Then heat it WITHOUT ANY FLUX to get a black oxide. When
you remove it from the pickle, it looks just like 22k. Rouge polish
of use a soft brass brush to polish it.
This alloy is great for casting and rolling. It will work harden
very quickly. Great for ring shanks, but a bear for bezel setting.
Takes some getting used to, but I love the color. It may look like
22k, but it sure doesn't work like 22k. One of the things I love
about working with gold is that there are SO many alloy
