you are right about the difficulties of getting
ready-made 22ct gold. It’s probably even more difficult in WA than in NSW.
If you want to DIY, you could melt up old sovereigns (shock, horror) or
melt up a batch using any one of the following recipes: 91.6% fine gold
(Au) + 8.4% fine silver (Ag), no copper (Cu) good for enamelling. 91.6% Au
- 5.5% Ag + 2.8% Cu 91.6% Au + 4.2% Ag + 4.2% Cu. Lovely rich colour.
91.6% Au + 8.4% Cu. Reddish hue.
Depending on how much you want, there are several companies that will make
it up to order for you. I’m fairly certain the following would have agents
Johnson Matthey Ltd.
Golden West Refining Corp.Ltd
Alloy and Gold Supply
All these supply the industry and would also advise you on 22ct alloys
appropriate to your needs.
Kindest regards from Rex in Sunny Sydney.
