Hi Robert and list I can't comment yet on the polish as I don't believe I have a large enough piece or stone that isn't already polished, but I'm getting great results on my thin sections with 1000 grit. I use a two part epoxy, they only have to be resistant to yellowing and uv degradation and of course, clear. Super glue is hygroscopic which means it wants to attrack water over time (unless they've gotten a better formula) and it will become brittle and loose adhesion (they learned this the hard way in implantable pacemaker assembly). Opticon is good, but its a tad expensive, as is the uv curable epoxies. I currently am trying a clear fly rod 2 part epoxy which seems to give good results. It has a added feature in which it is somewhat flexible which most other epoxies aren't.

I take my slices and go up through 600 and maybe 800 then still don't get that great finish. Is it diamond.... Question 2.  I've been making up some thin sections. Using the lap on a facetor. Does pretty good job. Several have come out great on the polarized microscope. But the glues that you use on the slide. Super glue is not so good. Opticon is best so far, any ideas.
