I haven't seen a roll of acid core solder in perhaps 20 years. Most
plumbers that I'm acquainted with use sold-core solder and flux.
Liquid-cored solders tend to sputter when being used and spew flux
everywhere--they were a lousy idea. After all, you need only flux
the surfaces that you're going to solder befor you heat them--you
don't need flux mixed into the solder.
Other than for convenience, I've wondered why rosin-core solder
exists. Better to flux then solder with pure solder.
And the new crop of fluxes are acid-free and clean up with water.
Better living through chemistry.
