Silver solder flux

Tried water ? I can't see a flux with HC solvents of any kind , my money's on water .

The stuff in the little plastic can with screw on lid? Yes, water. Done that many times.

Mine are in a ziploc bag because over time the plastic lid cracks and the stuff dries out . Pain in the a** to have to try to get some usable when you need it , this way it stays usable .

For joining which metals? Regular old NoKorrode works on most stuff and is much easier to work with than the liquid acid fluxes, like Harris Stay Clean, which are only necessary when you need something more aggressive. On stainless, for example. And I've never seen that dry out - I have a bottle of All State Duzall that's old as dirt and is just fine.

For the folks about to jump on me for suggesting NoKorrode, Stay Brite is a low temp silver solder. Its melting point is lower than 95-5 lead free solder's.

I didn't know another fan of nocorrode existed! Great stuff, but I've never used it on silver solder.

The best stuff for silver solder is at your jewelry making supply. My local guy sells one that is in a spray bottle, he calls it "Crystal Flux". I don't know if it is a commercial product or his home brew. But, your guy will have something similar, I bet.

water disolved it, thanks

I've been using plain old borax/water for years on gold and silver.

I juust keep adding a bit of water and mush it around in the container, been using the same 8oz. container of H&H" Handi Flux" for around 40 years.

Karl asked about silver solder flux:

Karl, did you ever mention what you were soldering together?

For copper and brass (like refrigeration and plumbing), I like the fluxless (or more precisely 'self-fluxing') silver solders, like Forney's Sil-Flo (and others). Note that they are NOT coated with or containing a flux of any kind; their self-fluxing nature has to do with the metallurgy.

Even a trace of even a non-corrosive flux getting loose inside a refrigeration circuit is a bad idea. Those types of solder eliminate that chance. That they also make doing a sweat joint so easy that even beginners can do it well is a boon.

I had a tiny cresent moon shape part to attach permanently to the top cover.

Karl Townsend fired this volley in news: snipped-for-privacy@4ax.com:

Well, the self-fluxers won't work on steel. They're copper-alloy specific.
