Hi most wonderful Orchidians
Rhodochrosite as you have discovered is soft.
It requires a light touch on the final finish… I find tin oxide to
usually you can go from 600 to finish on the leather… I use soft
elk hide for finishing… also a slow wheel for the final polish makes
a huge difference… I have a separate 300rpm wheel on my flat lap
just for the final polishing…
You can see some finished pieces of rhodochrosite on my site at:
Soft minerals are a near challenge… the Ruby in zoisite on my site
has take some real experiments to get a high polish on such disparate
minerals… from 6 mohs to 9 mohs for the ruby…but worth the
effort big time :>)
Enjoy your journey!
all the best to the finest online group anywhere.
