RE: BRYONET: Hoyer's Solution & chloral hydrate


Daer all,

I have used both glycerin gelatine and Hoyer's for years. When I have just
added Hoyer's to a slide many details become clearer (like in KOH).
The disadvantage of Hoyer's as mounting medium is that after a while the
contrast of tissues tends to become less so that many details become
invisble, also (like in glycerine gelatine) the slides dry out. Many of my
glycerin gelatine slides (rounded with nail polish) have lasted for over ten
years, but eventually (after 15 -30 years) they all dry out and/or get
infected by fungi.
