We wash our rocks in a colander over a plastic bucket so none of the mud goes down the drain. If the rock mud is allowed to dry on the rocks, it is almost impossible to wash off. Be very clean! Before you replace the lid on your barrel, be sure that both the lid and the rim are perfectly clean. This will allow the lid to fit tightly and prevent leaks.

For burnishing we grate up a bar of Ivory Soap with a vegetable grater. See our video about burnishing polished stones.

Your slurry should be a little thinner than in the last step varying with the softness or fragility of materials your are processing. Your goal again in this step is to see that all the scratches from the first step are ground away, and the rocks have a smooth, matte finish.

Using a magnifying glass may help check for smoothness. In this step the goal is to make the rocks extremely smooth. As always start as with Steps One and Two, put cleaned rocks in the cleaned and fresh barrel to make a full load. Use a pre-polish of either silicon carbide or aluminum oxide for this step, about 1 tablespoon per pound of load, and then add water up to the bottom of the top layer of rock.

Tumble time here is up to 7 days, with more checking slurry consistency and general progress every day or two. You may be pulling some of the rocks out earlier than others as they will become smooth sooner and even show some luster. For softer rocks, you may need to do a second pre-polish step or just keep them in a little longer. At the end of this step it is most crucial to really clean the rocks and barrel which will be more difficult as you are using a finer grit. This is so important because any grit can ruin the progress of your rocks in the final polish step.

By this time your rocks are looking pretty good and ready for that lasting final shine. You have been extra diligent on cleaning the rocks and barrel. Place your rocks in the tumbler and add Aluminum Oxide Polish, about 1 tablespoon per pound of rock. Step four takes up to seven days but be sure to check the rocks as you are proceeding because some will be finished earlier.

The best check for completed rocks is that they look as now as they would if wet. Once that is the case you are done with this step. One final detail, its best to clean up now by cleaning your equipment thoroughly before everything dries and encrusts.
