The rim is shaped like a clam shell, and the bowl is crafted in a smooth, square form from the rim to the body. While the “Masu” (Fig. 1) is known as a classic example of a square tea bowl, Dōnyū favored creating vessels of this shape. A distinctive feature of most of these pieces is that the clay is left exposed from the footring to the lower body. Here, too, Dōnyū’s unique touch is evident in the rounded lower body, and the interior is crafted to be wide and generous. A thick layer of curtain glaze covers both the interior and exterior; some areas where the glaze has cracked have turned yellowish, and it is likely that the name “Yūka” (Evening Haze) was given in reference to this appearance. The sharp definition of the rim is particularly interesting; furthermore, the “Raku” seal is clearly stamped in the center of the footring, and five glaze marks remain inside the footring. This piece serves as an excellent example of a work with visible markings. From the Fujita family collection. On the underside of the box lid, Yutaku Sai has inscribed: “Nonkō Black Tea Bowl, titled Yūgasa, Left (Seal).”
