has anyone got a alloy recipe for 18 k.y.g. solder? does anyone
make there own solder.
You can use this procedure:
Let’s say you need 18k yellow solder. Set your scale for grains.
1 dwt = 24 grains
1 dwt = 18 grains of gold and 6 grains of alloy.
Add 1 grain of copper and 1 grain of silver you got 18 grains of gold
and 8 grains of alloy.
in karats = (24 * 18) / (18 + 8) = 16.6k solder.
Melt it on charcoal and roll it very thing.
cut in strips and melt it again to insure uniformity.
Gold content will rise to approximately 16.7k Now it is ready to use.
The solder is not as easy flowing as commercial and requires more
soldering skills. It is almost impossible to unsolder, which is a
benefit for some projects.
