For larger surface areas, it's best to move to a mid grade disk like a 100 or 140 grit to slowly grind down your surface and get it prepped for polish. It may be more steps, but it will be more efficient and move faster in the long run when all your disks wear evenly. For smaller surface areas, you can easily move from a rougher grit like 60 or ...Web

Our four main abrasives when coldworking glass are: diamond, silicon carbide (carborundum), aluminum oxide, and pumice. Diamond is a 10 on the Mohs scale, so it is one of the hardest substances on the planet. Silicon carbide and Aluminum oxide are both a 9 on the Mohs scale, so they are slightly less hard than diamond.Web
