So how do you tell what grade of solder one is? I've tried
lining up pieces and hitting with the torch to see which melts
first but can't heat them all evenly to find out.
G’day; How about cleaning and fluxing small pieces and laying
them fairly close together on a piece of flat metal about about
1/16 or so thick and heating strongly from below? Not brass-
that melts below enamelling grade solder. Worth trying, I
reckon. I tried it and got a good result, but the metal had to be
red-hot and I had to be a bit patient.
