Teadust glazes are found in a variety of tones. Those referred to as 'eel-skin' are among the most prized by traditional collectors.
Compare this vase with two other teadust vases of the same form, the first illustrated in Chinese Ceramics in the Idemitsu Collection, Tokyo, 1987, pl. 229; the other in the collection of Mr. Matsuzo Matsumoto, illustrated in Sokenan Bijutsu Shusei Zuroku, Kushu Denki Kido Gaisha, Japan, 1993, no. 206, however both vases are of darker tone than the current example.
Compare also to a ru-type vase of this shape included in the exhibition held in Toyota prefecture, The Hirota Fukkosai Collection, Ceramics, Tokyo, 2007, fig. 169, now in the National Museum of Tokyo.
