Black Flux for Silver Soldering – Approx. 10ml or .75oz.
Black flux is used for intense localized heating.
Sold as a two pack. Keep one closed till you use up the first one.
Tip! If your black flux has dried out, don’t order another (no,no) simply add water!
Just add water a few drops at a time and stir till it’s back to the consistency you prefer.
