Greetings, all. I’m making some going-away presents for people at my current job, and for one guy, I have a nice piece of picture jasper (looks like sand dunes under a blue sky). I wanted to make it all nice and shiny, but apparently it’s too big to work with a carbide belt machine, and not flat enough to flat lap (and also I don’t have the time to flat lap it).
My understanding is that there is some kind of epoxy or sealant or something that will make it look somewhat polished. Are there any suggestions from you all?
