Does this tumbler is suitable for polishing shuttered glass? Will it be able to even out the sharp edges of the glass shutterings? I wanted to pillish glass particles to mimic sea glass which is rounded snd safe for holding it in hands. Do I need to use some kind of polishing granulate, wchich kind? Thank you in advance for your response
