    can anyone recomend a flux for low temp silver solder?

    By low temp silver solder do you mean silver bearing lead or tin based solder melting about 400 to 500 degrees? If so use any commercial solder flux. I prefer to use "No-Korrode" flux because it stays where you want it.

    If you're looking for especially clean joints then use a zinc cloride acid flux but clean it up thoroughly afterwards and neutralize the acid.

    As with any soldering operation work with clean bright bare metal.

        Yes Forrest, thats the stuff. I have a problem with the flux turning black like its turning to carbon before the work is hot enough to melt the solder. I have tried a couple of fluxes, maybe I will try some more. By the way Forrest, I find your writing in H.S.M. very informative. I am not a rookie in the maching area but I never fail to learn new things from your articles.

        Brownells used to sell a flux called blitz, I think. It worked pretty well but they don't seem to sell it anymore and won't ship any flux they do sell,to Canada.
