I use hard silver solder for my electrum soldering. If I amsoldering a 22k bezel to the surface then I use 18k solder. I trynot to solder, I usually fuse. electum fuses nicely.

You will have to make your own solder. But it isn't too hard to do.If you add about 1% fine silver to your alloy it should lower themelting temperature enough to act as a solder for the original alloy.Cadmium will work even better but it is toxic so you must use verygood ventilation when soldering or melting. Make some solder thenroll out a thin sheet of solder and a piece the original alloy to thesame thickness. Now melt both samples side by side. this trial willgive you a pretty good idea of the melting temperature of the solderrelative to the original alloy. Keep in mind that the lower themelting temperature of the solder the greater the color differencewill be.
Hope this helps. Good luck.Jim Miller
14k white in med. and easy work for me. Hard is a little to hot forthat alloy. IMHO.
