One pound of my favorite 120/220 blend of silicon carbide rock polishing grit. Rock polishing grit can be used to polish rough edges and surfaces of things like wine bottle drinking glasses, and trinket boxes. It can also be used to remove the shiny surface of glass for things like mica painting and making glue chip glass.
For best results, use a small amount of grit and water on a flat sheet of scrap glass to create a slurry. Rub the slurry around in a smooth figure 8 pattern until desired polishing result.
