Rock Tumbling Instructions
This four-stage silicon carbide grit for rock tumbling systems is the ideal way to give rough rocks a smooth, polished look. The first rock polishing stage smooths rough edges and provides initial shaping. The second smooths the rock surfaces even more. The third stage provides a strong pre-polish, followed by the fourth stage which completes the grit polishing process.
The 10 mL scoop in the grit refill kit ensures accurate grit measurements for every stage, allowing you maximize your grit usage for up to 9 kg of rocks! This grit refill pack is compatible with any rock tumbler on the market, but for best results, use this rock tumbler grit and polish refill with National Geographic rock tumblers and rock tumbling supplies, including ceramic media and GemFoam.
