[Histonet] paraffin wax

[Monfils, Paul]

Yes, we do want to avoid "slow cooking" our tissue samples by extended
exposure to heat.  However, 7 hours at 59 degrees is not likely to cause any
major problems for an average size specimen.  It could cause problems for a
small biopsy!  You can tell when you section it.  If it sections normally,
it should look normal microscopically.  If it doesn't section as well as it
should, soaking the faced block in water for 15 to 30 minutes before
sectioning should help.
