    I'd think the 24 ga is a little bit thin, not because it's mokume but
    just because it's pretty lightweight for the rough and tumble
    environment that a ring is subjected to... but then I tend to build
    things like unto an Abrams tank so don't take that part of my reply
    TOO seriously ;-) 

    With regards to the copper, nope, Baldwin's won't save you. It's
    pretty but won't permanently prevent further oxidation. 

    I have been counseled by people whom I trust implicitly that copper
    (pre oxidized or not) will tarnish and, in the presence of other
    metals, will form galvanic cells (causing rapid depletion of the
    copper). In general copper or copper alloys shold not be used in a
    ring, at all, ever. Hands sweat (a lot!), get wet, exposed to soaps,
    chemicals, etc, and copper will turn into a nasty mess when used ON A
    RING in no time, even on people who exhibit little sensitivity or
    reaction to copper in general. 

good luck,
Kevin
