This is going to be my first post. I’m based in Kathmandu, Nepal. I
have a small jewelry shop in Kathmandu and suiting small jewelry
workshop adjacent to the shop with 5 jewelry makers.
Does any member know how can we make a gold soldering alloy with 97%
pure gold with mixture of 3% of other metals? Zinc mixture is not
practical when soldering tiny piece of jewelry. Read somewhere that
Gallium can be a good option. However, I do not know much about that
metal. Cadmium is restricted metal in Jewelry in Nepal. Please advise
if any one has an idea. Thank you.
