Incised decoration
Incised decoration is a ceramic decorative technique in which lines, patterns, or images are carved into the surface of clay before firing. The decoration is typically created when the clay is in a leather-hard state, allowing the potter to cut clean lines into the surface.
The technique is usually carried out using sharp tools such as needles, knives, or specialized carving instruments. By removing small amounts of clay from the surface, the potter can create linear patterns, geometric designs, or figurative motifs.
Incised decoration may be used on its own or in combination with other techniques. In some cases the carved lines are left unfilled, creating subtle surface patterns. In other cases the incised areas may be filled with slip or glaze to produce stronger visual contrast.
In Japanese ceramics, incised decoration has been used in various pottery traditions and may appear on bowls, plates, and other vessels. The technique is closely related to methods such as Mishima inlay, where carved designs are filled with contrasting slip before firing.
Because the decoration is cut directly into the clay surface, the patterns remain permanently embedded in the ceramic body after firing.
