Very interesting! Thanks for this new info, Paul. :)

I found this written by Adrian: "A problem with wet preserved material is that dusting is hard to see . However it is usually possible with a bit of experience and changing the lighting and background carefully. I find that alcohol preserves morphology (apart from dusting) much better than does dry-mounting but colour can be a problem. Experience with a particular key usually solves this problem but not always, especially as wet material tends to fade." :) in
