The Seto Kilns were opened in northern Aichi Prefecture in the 17th century and represent the origins of Japanese pottery production. The kilns first manufactured ash glaze pottery (similar to beginnings of Chinese ceramic art) and brown glaze pottery. Formal porcelain production began later at the start of the 19th century. Blue and white porcelain is the Seto Kiln's main ceramic, with celadon production being somewhat rare, and the majority of its pottery items use a light green glaze. This particular celadon inkstone has incised on the back the following inscription in blue and white porcelain: “By the Owari Seto potter 穎溪 (Katokichi Mamoru). Commissioned by Duke 應鈴 in the 花 Month of the 庚辰 Year of the 文 Government.”
From this inscription we know that this piece was made by Katokichi Mamoru at the Seto Kilns in 1820.
