Have you experienced glaze running down to the bottom of your cup, leaving messy foot rings? Or do you simply need to polish the base of the cup? Here's the game changer: our diamond grinding disc. Just place the disc on your pottery wheel along with the batmate, and use it to lightly grind and polish away the unwanted texture.
 
Come in two different grits:
120 (Coarse/Medium)
240 (Medium/Fine)
 
Note: must add water while polishing.
