Good morning, Dr. Tobias.
	It looks like you have received several replies with good
information.  Here's an additional point you might want to consider.  If you
are being inspected by CAP, they no require documenting of the temp of
tissue floatation water baths.  (They did in the past. Apparently, common
sense prevailed.)  Histotechs are instantly aware when the water bath temp
is not correct when they place tissue on the water.  Too hot = excessive
spreading or disintegration of tissue section.  To cold = folds.  The
melting point of the paraffin determines the desired floatation bath temp.
The appearance of the ribbon on the water bath is THE best indicator of the
appropriate temp. 
	Good luck with your preparation for accreditation.
With kind regards,
Jeannie Fisher
