What were you trying to make? Soldering flux (usually a mix of zinc

conductive.


That's acid plumbing solder for copper pipes.

But you brought up a question. Electrical solder is rosin. What exactly
is roisn and how does it work for a flux? Is it the same thing used for
playing a violin, which as far as I know, is made from pine tree sap?
