How would I "charge with rouge"?
I would not polish coral beads with rouge charged walnut shells.
Rouge is better used for polishing metal.
My "secret recipe" tumble polishing compound is 1 part crushed
walnut shells to 1 part baking soda used dry. I use a vibratory
tumbler. It should work as well for barrel tumbler. Try it and check
it frequently and see how it does. I use it on polishing up heirloom
jewelry with set stones. That is before I got an ionic cleaner. But
still resort to the walnut shells and baking soda if the customer
wants to maintain some of the patina of the piece.
If the walnut shells and baking soda don't produce the desired
results. Try Tin Oxide or Pro Polish in a tumbler with water and
plastic beads. Check often to be sure you are not polishing down to
