FAQ:

Q: Can You reuse tumbling grit?

A: No, you cannot reuse grit. During the tumbling process, the grit breaks down and should not be used anymore, especially for the polishing stages. It will scratch your tumbled rocks. The rocks and the barrel must be thoroughly cleaned before passing to the next phase of the tumbling process.

Q: What is the best grit for polishing rocks?

A: Polishing grit comes in coarse, medium and fine grits, just like sandpaper. The 80 grit is coarse, like unground sea salt; 120 and 220 are medium grits comparable to sand; 500 is the finest and feels like powder. It is possible to make your own polishing grit with quartz and a lot of elbow grease.

Q: What is a rock tumbler?

A: Rock tumblers are small machines, usually small enough to rest on a tabletop. They consist of a motor, a barrel, and a chassis upon which the barrel rests. Many tumblers have only one barrel, but there are models that use two barrels at the same time. Rocks and water are loaded into the barrel, along with some type of abrasive grit material.
