Chatter marking is made by applying a springy metal tool to the surface of a slipped pot. The tool bounces and creates a rhythmic pattern of nicks in the slip, exposing the contrasting clay underneath. As the pot revolves on the wheel, the blade is applied to the slipped surface.
It takes some testing and experience to determine the correct state of dryness, the correct speed of the wheel, and the desired chatter pattern. If the slip coat is too wet, the blade won't skip. If too dry, the surface becomes impenetrable.
