This Kingsley brand grit kit used for rock tumbling and polishing contains 1 pound each of 80, 220 and 600 Silicon Carbide grits, plus 4 ounces of Micro Alumina Polish compound. This kit will polish 8 to 10 pounds of stone. Each level of grit will need its own stage in the tumbler. Be sure to follow the instructions included with the specific rock tumbler you own. To get started: Place your rough rocks into the barrel with coarse silicon carbide abrasive (80 grit) and water. The barrel must always be at least half full for the tumbler to operate properly, but take care not to overload. Barrels more than 3/4 full (including grit and water) may be too heavy and burn out the motor, and might not allow enough space inside for the rocks to tumble. Add the recommended amount of coarse grit and then add enough water to reach the bottom of the top layer of stones, but not so much that they are covered. You want to see some of the rocks above the water. Clean the inside and outside rims of the barrel and the edges of the lid. Make sure the surfaces that will form the seal are clean and dry. Place the lid on the barrel and seal the barrel. Put the barrel on the tumbler and start the motor. Wait a few minutes to make sure the tumbler is running smoothly and the barrel isnt leaking. If the barrel is leaking, stop the machine, remove the lid and re-clean the surfaces of the lid and barrel that form the seal. Double-check that they are clean and dry. Replace the lid securely and proceed. Also, check the tumbler in a few hours again to make sure its still running smoothly. After this, it can probably be left unattended, but its not a bad idea to check the tumbler every few days. Although it takes years and years for nature and its elements dirt, rock, water, and sand to smooth a rock\'s surface, lapidaries can get those same results in considerably less time using this grit kit in a rock tumbler.
