The Perfect Tool for cleaning up and smoothing out the bottom of your ceramic ware. Best results are if you use water to lubricate the sanded surface as wet sanding cuts down on dust created. Always wear a respirator or N95 dust mask when sanding ceramics. We recommend wet sanding starting with the 60 Grit, and working your way to the higher grit numbers. At 1800 grit your pieces will feel smooth as glass!
