1.) Tumbling works best when all of the rocks in the barrel are about the same hardness. If soft rocks are tumbled with harder rocks, the softer rocks will wear away quickly - before the harder rocks are properly shaped and smoothed. 2.) Tumbling works best when all rocks in the barrel are of the same type.
