Surface Enrichment of Clay

Rule 9a. Surface enrichment of clay must be so designed as to be able to withstand the action of heat to which all ware must be submitted.

Rule 9b. Incised, pierced, and modeled decoration in clay should be simple and bold and thus adapted to the character of the material.

Rule 9c. A border should not be located at the point of greatest curvature in the contour of a cylindrical form. The contour curve is of sufficient interest in itself at that point.
