I was trying to use some silver solder paste that came from Rio
Grande, delivered via a large plastic syringe.
However, it’s all dried up in a lump which cannot be removed without
cutting open the syringe. Don’t blame me, it was a gift from someone
That said, how can I salvage this as solder? Do I take the plunger
out and put in some solvent such as water or alcohol? Or do I just
remove the solder, hit it hard with a propane torch to melt it into a
charcoal recess, and then roll it into sheet solder?
