Instructions
Wash rocks in soapy water. Scrub with a brush while washing to remove all possible dirt and debris. Sort your Mohawkite rocks by size and hardness. Place them into groups of similar size and hardness.
Fill your tumbler barrel approximately half-full with Mohawkite rocks. Weigh this amount of rocks. Add 1 lb. of medium grit to the tumbler for every 10 lbs. of rocks. Add 1 tbsp. of baking soda to the tumbler to neutralize any gases.
Add water to the tumbler barrel so that it is just below the top of the rocks. Do not allow the water to fully cover the rocks by more than 1/16."
Place the barrel onto the tumbler machine and turn it on according to the manufacturer's directions. Observe the machine for a few minutes to make sure there are no strange sounds coming from it.
Leave the Mohawkite rocks in the tumbler machine for four to six days before removing. Clean the rocks and machine with water once you are satisfied with the polish of the stones.
