Our protocol is to:

Use a positively charged slide
Fix in 10% formalin for 1 minute
Rinse in tap (a few dips)
Gill 3 for 1 minute
Rinse in tap (a few dips)
3-5 dips in bluing
Rinse in tap (a few dips)
Eosin 2-3 dips
100% ETOH (a few dips)
100% ETOH (a few dips)
Xylene (dip until clear)
Mount with Richard- Allan Mounting Medium

After the Gill3, Eosin, and last alcohol, the back of the slide is wiped clean of excess solution to prevent carryover.

We do this frequently. 
Fix slides in Methanol (45ml) + formaldehyde (5ml) for 10 minutes. 
Wash several changes of tap water
Stain with Harris Hematoxylin for 3 minutes Proceed as you would for paraffin  sections Get great staining. 
I am sure if you are using a different Hematoxylin you could use it the same way you use it for paraffin

Does anyone have a good protocol for staining frozen sections with H&E?? Also, any mounting medium suggestions?? This is the first time I've been asked to do this for frozen. 
Thanks a bunch everyone!
