This is the only flux I use for silver soldering. Before using it I could never get solder to stick. I tried several other fluxes and thought flux is flux. Obviously I was wrong. You must use the correct flux for the type of solder and type of metal you are working with. This is made for high quality silver solder and is excellent for this purpose. Always read the label on your silver and flux to make sure you have compatible products. That being said, if you start with a really clean metal, apply a liberal coat of flux, and use the right solder, the rest is just practice knowing when you have a hot enough part without overheating. Not enough heat, the solder will not melt. Too much and he will run away without "sticking" to the joint. This thread meant everything to me. From the inability to get the solder to flow into the connection and succeed 99% of the time.
