- Ceramics
- Technique
A technique used in creating Bizen ware. In the normal nerikomi (literally, “kneading”) technique, different clays are kneaded together by hand to form a pattern.

This allows the variations in the composition of the original clay to be utilized, and the surface of the work can be made to look like a natural geological formation.
