Is there copper or brass solder so we can solder without leaving
silver solder lines in our work
Indian Jewelers Supply and Thunderbird Supply, both out of Gallup,
NM, carry brass colored solder. Both companies are online. This solder
does fine for red or yellow brass, but is too light for copper.
Orchidites mentioned using pre-1965 pennies rolled through a mill for
solder for copper successfully, as they have the right composition for
zinc and copper. Personally I haven’t tried it yet. Hope it helps.
