    I do a lot of married metal pieces with copper or bronze combined
    with sterling silver. I patinate the pieces with cupric nitrate and
    heat until it turns from turquoise to black. I repeat this process
    for about 3 or 4 applications to create a deep black. I then gently
    scrub the piece with superfine steel wool. The cupric nitrate doesn't
    like to adhere to the sterling, so I end up with silver and black
    patterns.  You can get a brown colour by only applying one or two
    solutions. You might want to try that.
