I can't swear anyone else will be interested, but I will be! Somewhere around here I have a couple of digital microscopes, one kid's toy, and one "real" scientific tool from the 90's or maybe a bit later. In the drawer next to me is a student's optical that I bought as pieces and am slowly putting back together. Whoever took it apart in the first place lost all the screws, or used them to fix the other identical microscope in the bag. Also a small tub of cerium oxide I bought when I was a teen for lapidary work. How I've managed to hang on to it for all these years, I couldn't tell you...

Expect in one hand, expectorate in the other. See which one gets full first.

If you look at the various abrasives under a microscope (electron) you can determine the shape. Silicon carbide is sharp for instance. Rouge is almost round at least is when milled, about 250 nanometers in diameter and very consistant in size.
If interested I can post the scans in a few days. I have several optical polishing g compounds and may have AlO.
