    Hi Sandra, Is there a reason why you want to do this with clay?  For
    over 30 years years now I've been using either a dental impression
    material called Aquasil, or Castaldo's Quick-Sil, or one similar to
    Quick-Sil that I got from an audiologist.   All three self-cure, the
    Aquasil taking about a 15 minutes at 70F (surface temperature) and
    although the container on Quick-Sil says 15 minutes I find it takes
    closer to 30.   In the Arctic two summers ago it took overnight! 
    It's not easy to warm a rock surface to 70F in the Arctic, or on the
    coast of Newfoundland for that matter! 

    All products involve mixing two parts together.  Aquasil is about
    the consistency of toothpaste and gives the most detailed
    impression.  It's also messier to use.  The other two are putty-like
    and easiest to use in the field. Both give very good results.
