microscope slide crystals - mounting medium

soreff - 28-7-2022 at 10:49

I'm planning on growing some small crystals of water soluble compounds
(e.g. alums, Tutton's salts) in microscope well slides.
These all crystalize as hydrates, and tend to lose water if exposed to
air. I'm planning on sealing them in with cover slips, with mounting
media sealing the cover slips to the slides.
Does anyone have a recommendation on which mounting media are
least permeable to water vapor?
An old material used for the seal is canada balsam.
Does anyone know if this is the best choice, or if there is something
better?
Cyanoacrylates?
Epoxy?
Something else?

Does it harder between two glass surfaces? Does it harden by evaporation or polymerization?

Yes it does harden between glass, been using it for years as a mount. I believe evaporation.

Integrated circuits are embedded in epoxy resin so I guess it would be a good choice.
Polymerises, adheres well to clean glass,
I like Araldite rapid, maybe not THE best but excellent and easily available.
