Wayne, Thanks for that extensive explanation. It’s all new to me and
makes complete sense.
My handicap is that I’m self taught in the lapidary area and never
heard of most of what you describe.
As for bonded laps, I’ve never thrown one out. I have a foot locker
full of laps. Once they’re no longer useful for stone they are very
handy for sharpening tools.
Thanks again for your explanation.
