I have  a old can of Fine Line 2000 paste that have hardened up, flux dried or someting, is it possible to soften it down again? Or is it EOL/Expired/DEAD on ARRIVAL?
Hmm,  borax and water ? Brazing flux is potassium salts of Boron and Fluorine if withe if black  +boron? The can says silver and antimon?!
Pure in some alcohol or water and stir , no?

Hi
If you wish to use it to solder copper water pipes, there are ways to still use it. For it's intended use, not so much.
