Ryan ★★★★★

The flux flows on way cleaner than the paste I used before, and the self-pickling part means I spend a lot less time at the pickle pot afterward. Joints on my silver rings came out smooth even at the higher temps.

Eli ★★★★★

I mostly work in silver and this flux keeps the solder flowing right where I want it instead of balling up. It's a liquid so a little goes a long way, and the joints came out clean enough that I barely had to pickle afterward.

George H. ★★★★★

The self-pickling part is what sold me, no separate pickle bath after soldering gold bands. It flows right at the higher temps I run and cleanup is way less fussy.
