    Carla, All you need to do remove the calcium is place the shells in a
    pyrex dish of warm apple cider vinegar cut with a bit of water.  Let
    them soak for about 30 minutes and rinse.  Calcium that didn't
    disappear can be knocked off.  I would suggest using Muriatic acid
    but that can be pretty strong and hard to gauge the length of time of
    soaking. 

    Cheers from Don at The Charles Belle Studio in SOFL where we are
    getting ready for the big Palm Beach Gem and Mineral Show, and where
    simple elegance IS fine jewelry! dcdietz AT comcast.net
