Specialties. Joseon tea bowl, split high table, Koryo. It belonged to Yugyeong Shim, a Yugyeong general who came to Japan as a peace envoy during the Japanese invasion of Korea in 1592-8, and was given to the king of Joseon as a gift in case he was asked to give a speech in Japan when he was about to leave for Japan. After the meeting with Hideyoshi, he returned to Japan as soon as the peace agreement was broken, and presented this to Takeda Hoin, a doctor who had healed him during his stay in Japan. The Takeda family later gave it to Inoue Shinzaemon due to debt, and Shinzaemon sold it to Kyogoku Tango-no-mori Takahiro, lord of the Miyazu domain in Tango Province (Kyoto Prefecture), for 150 large gold coins in October 1639. After Takahiro’s death, it was given as a relic to his son-in-law Sadanao Matsudaira Oki, lord of the Matsuyama domain in Sanuki Province (Ehime Prefecture), and since then it has been passed down as a treasured item of the Matsudaira family. It has a brush-washed form, slightly tightened, and the mouth rim is slightly warped, with concavities on both sides and a small ear in the center of the concavity. The outside of the body has a shallow wheel that runs from the bottom of the mouth rim to the body, and a vertical line running the entire length of the body to the hem of the body. There is a large crescent-shaped fire crack from the body to the waist, and small penetrations appear on the entire surface both inside and outside. There are also some interesting scenes of blue and white glaze around the base of the bowl. The inside of the potter’s wheel is shallow and the wheel is a bit rough, and the tea reservoir is slightly concave with a mirror drop shape, and there are four irregular eyes. There are small repairs at the edge of the mouth, and there is a two-turned fire crack in the mirror fall. The shape is tight and tall for a brush washer, making it a unique and exceptional piece. The overall appearance is shiny and elegant with a blue-gray glaze, and in particular, there is a concave part on the mouth rim with an ear shape in it, which adds a kind of charm to this tea bowl, and it is no coincidence that it has been popular among tea masters since ancient times.
