The source of the name “AIDAI ISSEI SANSUI MIDORI” refers to the phase from a classical Chinese poem. The piece is made by using a hand-forming technique, which is the traditional style of Raku ware. This is a thin, shoe-shaped tea bowl. The notched lip is rightly warped like mountain roads. From the mouth to the low hip, a cobalt, a black glaze is poured in a belt shape contrasting with the underlying tone of an ash glaze. The area from the low hip to the trimmed foot is covered with a light cobalt glaze. It represents a state of the water flowing from the mountains seen in a great distant, being coloured in a deep blue. This work is one of the “Day Voyage” series.
