Each grit kit contains the following:
2 pounds of coarse grit
1 pound of medium grit
1 pound fine grit
1/2 pound of polish
1 bar of Ivory soap (for polishing & burnishing).
This is enough grit & polish to fully tumble approximately 12 pounds of rocks.
Why the Ivory?
Around here, we use a little bit of Ivory mixed with clean water + rocks between grit stages to clean (burnish) our rocks & barrels. We also like to add a little bit (1/2" cube) to our polish stage since it helps make clean up easier on your barrel & your hands. If you decide you don't want to do any of that, it's just great soap!
