Want that deep, glassy shine from your rock tumbler? It all starts with using the right grit in the right stage—and knowing when to add media.
In this Short, I break down the four key stages of grit (coarse 60–90, medium 150–220, fine/pre-polish, and final polish with aluminum oxide, cerium oxide, or tin oxide) and explain how ceramic pellets or plastic media help keep your barrel running smoothly—especially in the final stages or when polishing softer stones.
This clip comes from my full rock tumbling guide on Will O’s Southwest Studio, where I walk through each stage in detail, from rough rock to mirror shine, plus troubleshooting dull or scratched stones.
👉 Be sure to check out the full video on my channel to see the complete start-to-finish process.
