Hi, Sandra,

    Sorry to hear you are tearing your hair out over brass! 

    I've never constructed a brass box, but I (and my students) have
    worked with it a good bit. We've always been able to clean it up
    after soldering with the peroxide "bright dip". I find myself
    wondering whether part of the problem may be the brass you are
    using. It seems to me that the kind called "nugold" suffers less
    from copper-plating in heat than the others I've used, so maybe that
    would help... 

    There actually is a brass-colored solder: gold. Not necessarily an
    economical solution, but the amounts are pretty small. 

    Other than that, Indian Jewelry Supply sells "fos-flow #7". It is
    dark grey, but seems to take on color fron the metal it is used on,
    oddly enough. I've used it on brass and copper and had it pretty
    much disappear. It has a low melting point, as well. Plus, it is
    very cheap. 

    Good luck on your project! 

--Noel
