Just joined. I have had an interest in microscopy since childhood when I was given a cheap scope as a Christmas gift.
I have a couple of scopes that a little better now. A Nikon Labophot scope with a teaching head and an Olympus BH-2.
My interests include lepidoptera (butterflies & moths). I am really interested in learning how best to prepare slides of butterfly wings. Any suggestions would be greatly appreciated. I am really interested in how slides were made during the Victorian era.
I share your interest in wings and scales, particularly of old slides and those scales of species used as early test objects.
The old slides of butterfly wings in my modest collection use simple mounting techniques. A piece of wing typically less than 1 square cm in size has been cut and mounted dry, in a raised circular cell and sealed typically with black ringing.
When scales were mounted, especially if a test object, they were usually mounted dry. So would have had a slip placed on and again sealed around edge.
I do have one more modern commercial mount of a whole wing of a Monarch butterfly. This exploits the modern very very large (but possibly expensive coverslips that are available. This coverslip was just taped either end.
Although permanent mounts of scales are useful, its arguable if a slip covering on a wing aids its study. As epi techniques and epi objectives are ideally designed for uncovered subjects. Also the slip causes glare for simpler epi techniques. So keeping a part of whole wing specimen dust free and bringing out for study is one approach.

Greetings from Overland Park, KS.
Yet another student of the life sciences coming onboard. I'm currently a student at JCCC working my way into the Molecular Biosciences program out of KU Edwards campus. I'm currently driving a Ken-A-Vision T-1903 binocular compound microscope that I was able to find for a steal on Ebay ($75.00!). I've very satisfied with the instrument as a learning tool that will help me towards my degree and I hope to be able learn some additional skills that I can put toward my education. Hope to talk to you all soon!
