Iron oxide slip called oniita is applied to white clay unique to Mino, on which a motif is engraved via kugibori (a type of line engraving that makes the surface look like it is carved with a nail) and then a feldspathic glaze is applied. By using a technique based on the idea contrary to that of Shino ware that applies a rusty painting on the white surface, the Nezumi-Shino (gray Shino) ware that applies an outline motif on the gray surface was born.
This bowl has a tripod on its small bottom and the mouth that widely opens from the body is bent on all sides, displaying a spontaneous, free atmosphere. Iron oxide slip is applied casually from the inside to the outer surface of the bowl. Since something that looked like a rock accidentally appeared on the surface, it was used as a rock and a wagtail and river waves were engraved on it, while bamboo leaves were painted on it using iron pigments. The bluish color, which was probably produced accidentally, is rare for Nezumi-Shino ware and looks nice on the river scene. The clever representation created by a prompt response to the natural process of firing has successfully produced a lively, three-dimensional scene. There are four meato (traces of a base on which the item was placed when firing) on the back of the bottom. This is one of the best among the Nezumi-Shino ware.
