Kosometsuke cup fired in a private kiln of Jingdezhen in the late Ming dynasty. The shape that is the rim delicately outward is called Kabuto-gata (helmet shape), and a pair of horses painted with cinnabar and cobalt are drawn on four sides of the exterior body. It is an example called “Senkô-de” using underglaze red, but the copper-red glaze turns blackish and looks like dark bay horse colour. It was probably made as Mukōzuke, but it is a teabowl size enough to make tea. As if to symbolize the unity and intimacy of the two horses, a split pair are joined together.

The excellent Kintsugi is applied with the finest gold powder finish. There are no noticeable defects other than the glaze flakings on the rim and kiln grits in the interior, which is a significant feature of Kosometsuke.
