A question for the gurus of Histology.

Many years ago (and I emphasize many) the lab I trained in used a technique
for post treating paraffin sections to keep them on the slide through some
of the silver staining techniques.  It involved dipping the mounted,
deparaffinized slides in a mixture containing celloidin.  Does this ring a
bell out there, and if so do you remember the concoction and procedure
details?

Any pearls of wisdom would be appreciated.
