copper? Answered

I have only been working with copper since I can get it for free. Is there a solder that is copper so it will match the copper wire? I have tried soldering with a soldering iron and that goes well (no need for the pickle process), but the solder is silver-colored.

Not that I know of-- when learning this stuff in school I used copper for practice soldering shapes in sheet metal, and always used the same solder as with silver. Afterwards we'd file and sand as much of the overflow away as possible, then plate the solder joint with copper by using well-used pickle that has steel in it (has lots of copper suspended in it, and the steel charges the solution causing it to plate non-ferrous metals).

copper plating by the pickled solution isn't sustainable. Copper gets too flaky and too easy removed by polishing. Better to use flow stopping technic - cover area with chalk, where you want to no sign of solder. It is tricky but possible

Recently I have been reading up on metal working and jewelry making and came across 'copper phosphorus solder', this solder is self fluxing, so no flux needed, but can only be used to solder copper to copper (this is just what I read, no experience yet)...
