Hello Jennifer,

    I'm not sure I follow you. I think you might be saying that one uses
    a large container so you can fit your whole piece in it for a nice
    dunk and then torch it, yes?  So basically it's your firecoat, if I'm
    on the right page here. 

    I'd have to say that in my experience there are better mixtures for
    this. I happen to use a water-based home-brew recipe that I got out
    of Erhard Brephol's book but that's just my personal preference.
    Personally I use the borax/boric acid/alcohol mixture as a soldering
    flux for my work with (standard) sterling silver and in that
    application I find the alcohol nice because it evaporates quickly.
    That helps me place solder chips, etc if that's what I happen to be
    doing at the time. 

Cheers,
