"The recipes dealt with the absence of chloral hydrate."

If I remember correctly Chloral Hydtrate is added as a preservative to
prevent bacterial/fungal growth. It shouldn't affect staining at all.

I have seen various Mayer's Hematoxylin recipes over
the months posted here. The recipes dealt with the
absence of chloral hydrate. My question is this:

Does anyone know what the staining intensity might be
like in 20 years if the slides are pulled from the
slide files. Especially if they use this for their H &
E stain.

Another way of asking: Has anyone been using this
recipe for awhile and if so, how do earlier slides
look after being pulled from the slide files?
