Soldering rose gold

Terry, because of the high copper content in rose gold it oxidizes
much more rapidly than yellow gold. 2 Possibilites exsist for your
problem, 1. You must heat the object at the jointyou are soldering
without overheating the solder, if the solder is sputtering you are
certainly burning it. or need to maintain a boric acid solution
over the metal to prevent oxidation to the rose gold. It will resist
the flow of the solder if not clean. Flame size & positioning are
"KEY" to any soldering joints. Also because of the copper content
rose gold tends to heat simiarlarly as sterling silver. It soaks up
and disapates much heat and you may be forcing the solder to flow
before the object is properly heated. I hope this helps
