Oops, damn - I actually learned something, now I'll have to go lie down for  
a while. Thanks Bruce.

>>Sorry, I should have clarified:  "Pyrolysis" literally  means breaking a
substance down by heat.  It is not truly burning,  which is the reaction
of the substance with oxygen.  However,  pyrolysis generally takes about
the same temperatures as does  burning.  The two reactions often occur
together.  Excess oxygen  leads to burning.  Limited oxygen leads to
pyrolysis.  Because  pyrolysis results is smaller compounds that may be
highly reactive, it is  definately possible that a drying effect could
happen.  (Whether it  DOES happen, I can't  say.)
