Does anyone know how to preserve fish scales and mount them?

Sorry, I don't do permanent mounts. I prefer wet mounts and photos.

Simple protocol, wash well with tap-water, then into >=95% alcohol, 2 changes (IPA is cheap and easy to get hold of) for about 4hrs total. Then simply mount in clear nail-polish with coverslip of course.

Should do the trick for a quick start.

In my field of work we age fish scales. The way it's done, for that at least. Is by making impression slides. The scales are put on a plastic acetate slide and the run through an impression roller mill. The pressure from rolling leaves a perfect impression of the scale. Which can then be viewed under the microscope for ageing.

I have a a whole bag I need to do for my next project.

I don't know how one could mount an actual scale due to the fact that they will always curl, which is why impression scales are made. I would suspect the scale would need to be wet so it won't curl.
