Love this Flux for Jewelry Soldering!
I use this now for all my sterling silver soldering. This flux really does it's job in 3 key ways for me! I have no problem with firescale. It helps the silver on silver and solder pallions on silver to almost stick together and stay in place in a way that I have not experienced with other flux. And...it is such a great indicator of how hot the silver has become and when the solder pallions are ready to melt and shortly thereafter flow. This brand of flux has improved my soldering success! Note: I do wear a mask when I solder.
