Trisha,
		the easiest way is to cover with a thin layer of paraffin
wax. This is
best done by heating the slide until the paraffin wax JUST melts and then
applying a thin layer of paraffin wax using a second slide. With a little
practice this can be done quite rapidly. Slides can then be stored as you
would  store paraffin blocks. Can also store these in the refrigerator.
Be careful not to use too thick a layer as this then takes some time to
dissolve in preparation for staining.
I still have some slides prepared in 1962 that have been stored in this
manner and staining appears to be unaffected.
