Tumbling Tips

To tumble soft material that is hard to polish, start with the second coarsest grit. Fill the tumbler 3/4 or 7/8 full so the stones will roll and not fall. About 1/4 the normal amount of cerium oxide polishes better that the usual polishes.

Get more out of your tumbling by adding specially shaped stones to your regular stones. Hearts, crosses, and elongated triangles made by cutting a rectangular slab across the diagonal are some of the possibilities.
