A Kogaratsu teabowl fired between the 1590s and 1600s at the Matsuura-type Dozono kiln. With its shape reminiscent of a tenmoku bowl, the bowl is covered with an ash glaze mixed with feldspar, reaching down to the waist. The kiln also produced works with a persimmon tenmoku glaze, further reflecting its connection to the Chinese Song ceramics within Japanese tea culture.

The bowl’s whitish lip, a result of natural glaze alteration, lends a delicate and fleeting nuance to the otherwise bold craftsmanship. Interestingly, faint pine needle-like patterns appear on both the interior and exterior, though it is unclear if these were deliberate or accidental. Even the fallen kiln grits contribute to the bowl’s charm, embodying the excellence of Kogaratsu.

Excavated and used over time, the bowl bears three old lacquer repairs on the lip and slight glaze chipping in some areas. It comes housed in an old box with an inscription reading “Kogaratsu Dozono Kiln Chawan.”
