Looking around for some DIY flux recipes and came across this one:
5% Potassium Nitrate (KNO3)
5% Ammonium Chloride (NH4CI)
Anyone have a strong opinion on this recipe? I know Potassium Nitrate is used in gunpowder as an oxidizer, but that seems bad for soldering right? I’m about 10% confident in what I’m saying about that though, so please chime in.
