The term tenmoku, derived from Mount Tianmu in northern Zhejiang Province, also refers to black-glazed bowls. Yuteki or oil-spotted tenmoku bowls were also produced at the Jian kilns in Fujian Province. The name yuteki describes the gold, silver and blue iridescent spots resembling the oil drops on the surface of the water. They are the result of crystallization of the iron contained in the glaze. In China yuteki is called dizhu or drops of jewel. The gold band covering the mouth rim is not only for reinforcing the mouth rim but also for visual attraction. This work was brought into Japan during the Kamakura period (1185-1333) and owned by Chancellor Toyotomi Hidetsugu (1568-1595), which was later handed down through the Nishihonganji temple, the Mitsui Family of Kyoto and the Sakai Family of Wakasa Province (present-day Fukui Prefecture). Weight: 349g. Three pieces of lacquer tray from the Southern Song dynasty accompany this bowl.
