Jordan,

Reasons for drying slides above the melting point of wax:
1.	Remove excess water
2.	Allow sections to attach to slides (otherwise they will lift off
in
the dewaxing xylene).
3.	Aid in final spreading out of sections so that there are fewer
folds
(should I say NO folds!!)
4.	Remove some of the excess wax (ie it flows off the slide).
Remember
this requires regular cleaning of the oven to remove excess wax.
5.	Can't think of any other reasons

Good Morning All:

My lab is in a huge discussion about the reason why we put our slides in
an
oven before staining.  I told them that the reason was to dry all of the
water off of them, because xylene and water do not mix.  This statement
is
also backed up in literature that I have read.  They still do not
believe
me, because they think the purpose of the oven is to deparaffinize the
slides.

Can anyone help me out, so I can put this discussion to rest?  I will
print
off all of your comments for my technicians to read.  Is what I told
them
correct or not?

Thanks.
