1. When completing work on a ceramic piece, you may find that certain areas have excess material, or "flashing," on one or more edges.
2. To remove the flashing and ensure a smooth finish, start carefully clamping the piece into the D-Vise. (It has cushioned clamps to protect your project.)
3. Using the #85422 silicon carbide grinding stone, work at the flashing until it's completely smoothed away.
4. You can also reshape areas or define detail using the #84922 grinding stone to create lines and features that are otherwise difficult to see.
