    My favorite solder for brass comes from a welding supply store --
    1/16" Lincoln Low Fuming Bronze brazing rods (BARE RBCuZn-C). 
    Despite their being called "bronze," they are a brass, as indicated
    by the zinc content, and are a decent color match for brass. 
    However, they can only 

    be used with red brasses, with a high (85% or more) copper content,
    because standard brasses (which contain more zinc and sometimes
    lead) have lower melting points than the brazing rods do.  The brazing
    rods can also be used with copper and nickel-silver -- the colors
    don't match, but the warm gold of the brazing rod creates a nice
    color contrast. 

    I use these brazing rods for decorative brazing on base metals. 
    When I use them as solder, I hammer out the rod somewhat (it is
    brittle) and cut it up into little pieces with my aviation snips.  I
    use the same fluxes as with silver soldering. 

    Shameless plug:  if you are a beginner, I'll be teaching a course,
    "Jewelrymaking and Metalworking," at Ghost Ranch, near Abiquiu, New
    Mexico, during the week of August 12-19, 2002.  It covers the
    basics, including hard-soldering, bezel-setting, decorative brazing,
    photo-etching, and more.  Their web site is <www.ghostranch.org>.
