Although the mounts I produce are for my own enjoyment, I recognize that permanence and uniformity is certainly desirable from a scientific and curatorial position. The more I think of it the more I feel inclined to break from my habit of producing semi-permanent mounts in aqueous media, though I will sorely lament the added time slides must be left unexamined as they cure.

It honestly hadn't occurred to me that I had been destroying important structures by speeding the process along, no doubt because I am sufficiently ignorant to fail to notice the absence of the destroyed features!

If I might impose on your expertise one last time; I general employ a 10% solution of NaOH. Is potassium preferable, and is 10% simply too strong do you think?

In any case, thank you, sincerely, for taking the time.
