Neriagede is an artistic technique for creating ceramic pottery by layering or blending of clay of different colors to create a striped or marbleized effect. It requires high level of pottery techniques. Quite simply saying, it can be a little like making a tiered cake (baumkuhen).

The Neriagede shaping process comprises the steps of stacking alternately a plurality of clay boards differing from each other in color, which creates beautiful striped or marble-like patterns. In order to avoid cracking and breaking which come along with mixing a variety of different kinds of clay or during firing, high level of thechniques and extensive experiences are required.

The thechnique of Neriagede is said to be derived from the marbeling tchnique (called “Kotai” in Japan) in the Tang Dynasty China in the 7th century. It is said to have been introduced to Japan around the Azuchi-momoyama period (1568-1598), for there are several pieces of Neriagede pottery, which were supposedly made in this era, have been found.

In recent years, the techniques to color the clay itself is invented and more complex and highly artistic works are being created. New “layers” of the techniques are overlapped on to the traditional “layers,” which continuously propels the development of this high-leveled ceramic ware.
