    If your raku shards are multicolored and iridescent, the color comes
    from copper, and behaves similarly to iridescent patina. That is to
    say, anything you put over it (including finger prints) will affect
    the color. You might be able to add opticon to the back to
    strengthen the piece-- allowing the glue to soak in from one side.
    The best use is probably to set the shards in bezels with E6000 or
    epoxy supporting the back.
