English: During the cultural trend of East-West exchange in the 16th century, China and Japan, situated in Asia, also embarked on a new chapter of mutual interaction. Aside from calligraphy and painting, a type of porcelain known as "kosometsuke" emerged in Jingdezhen around 1620, featuring both underglaze blue and wucai polychrome decoration. Distinguished by shapes and patterns deviating form the prevailing Ming dynasty style, some of these porcelain were suitable for Kaiseki cuisine, while other served as tea utensils.Regardless of whether ordered by Japanese tea masters, in the eyes of the tae ceremony artiats, the substantial texture and partial peeling of the glaze paradoxically became a showcase of natural charm and aesthetic appeal reminiscent of traces left by insect bites.
