How to Polish a Rock
For rock collectors, learning how to polish the rocks to bring out their natural beauty is as important as the collecting itself. Polishing a rock requires no extraordinary proficiency. It just requires patience and interest. The following steps will help you keep your collections at its best.
Use 80-Grit Sandpaper
After you wet the rock, sand it with the lowest grit (80-grit) sandpaper. Start sanding the rock in a steady, rotating motion. Keep dipping your rock in water while you are using sandpaper. Continue sanding the rock down till the desired shape and size. This process should continue till the rock achieves the desired smoothness.
Use 180-Grit Sandpaper
Wet the rock again and sand with a 180-grit sandpaper to eliminate the deeper scratches under the surface.
Use 600-Grit Sandpaper
Wet the rock once more and sand with a 600-grit sandpaper to smooth the rock even more and to remove the lighter scratches. Keep dipping the rock in water to remove the dust.
Polish the Rock
Wet and squeeze out extra water from a thick cloth like denim. Put a small amount of powdered polish on a damp cloth and polish the rock with the cloth in tight little circles rotating all around the rock.
Keep dipping the cloth in polish and buffing up the rock till you are satisfied with its appearance.
