The present example is remarkable for its exceptionally large size. Compare with a smaller example in the Zhejiang Provincial Museum, illustrated in Longquan Celadon of China, Hangzhou, 1998, pl.70; another discovered among a group of Song ceramics excavated at Lueyang, Shaanxi province, is illustrated in Wenwu, 1976, no.11, pl.6, fig.5; and a third is included in Chinese Ceramics in the Idemitsu Collection, Tokyo, 1987, pl.474. See also another zhadou of similar proportions but smaller size, illustrated by R.Krahl, Yuegutang, A Collection of Chinese Ceramics in Berlin, Berlin, 2000, no.226. Fragments of these smaller zhadou recovered from kiln sites at Dayao, Longquan county, Zhejiang Province, are illustrated in Longquan qingci yanjiu, Beijing, 1989, pl.6, fig.5. The latter examples appear to have much greener and slightly inferior crackled glazes.
