Question: What do I use to polish the Chrysoprase. I have
other Chrysoprase stones that also need polishing.
Tin Oxide with a leather buff works well. Basil (sheep skin leather)
works well stretched over a backing plate on a motor shaft, cow hide
also works but these leathers should not be oil cured as they become
slippery when wet.
Make a thick slurry of the tin oxide using water and brush a little
on to the dampened leather buff.
Work the stone around on the revolving buff and as the moisture dries
you will feel the stone start to grip on the pad, at this point you
should be getting a good polish.
Add more tin oxide if necessary.
You could punch small circles out of stiff leather and use them with
the same result on small spindles on your flex shaft.
I use this latter system to polish jade carvings using various grades
of diamond paste… If you have diamond paste in grades around
3000/8000 it should also work on Chrysoprase.
To polish your loose stones on a revolving buff you will need to
attach dop sticks to the back of the cabs to give you some control.
Suggest you talk to your local rock shop if there is one handy re
means of sticking the dop sticks to the cabs. People seem to have
their own preferences for this… I use araldite epoxy resin but some
people seem to find this too hard to remove.
