This is a Shigaraki-yaki tea bowl by Kiyotsugu Sawa (residing in Shigaraki-cho, Koka City, Shiga Prefecture), who also appeared on NHK's "Bi no Tsubo" (Beauty's Secrets) in January 2020. I obtained this directly from the artist and have never used it. (I'm listing it as "Like New" because some time has passed since I purchased it) Size: Body diameter: 13.5 cm, Rim outer diameter: 12.5 cm, Foot outer diameter: 6.5 cm, Height: 10.0 cm (Please allow for slight variations as these are amateur measurements) Kiyotsugu Sawa Born in Shigaraki-cho, Koka City, Shiga Prefecture in 1948 Graduated from the Kyoto Prefectural Ceramic Training School in 1968 Studied under Harusai Takahashi of Shigaraki in 1972 Became independent in 1981 Featured in the quarterly magazine "Tsukuru Tojiro 43" (with DVD) in 2008 As the size indicates, this is a large tea bowl. Weight: 649 grams I think the pale green natural glaze is a highlight. Comes with a signed box and cloth. There is a "ki" signature on the side of the foot. (He changed it from the previous "Ki") Thank you.
