Is there a method to determine how much of a compound has solidified 
during freezing?  For example, water placed in an ice cube tray will begin 
to solidfy when slightly sub cooled below 32 deg F.  If I wanted to 
measure how much has solidifed at any given time, how could I do this?  
Would some kind of light refraction measuring technique be useful?  Liquid 
and solid phases would be mixed with a moving interface.  Any thoughts?
