Chinese Art A celadon glazed cup China, Song dynasty (960-1279) . . Cm 20,00 x 8,50. Hemispherical cup with olive green coating. The external wall marked by the traces of the turning process, while the interior is elegantly decorated with a sgraffiato large stylized flower. This artifact is probably attributable to the so-called Yaozhou production, the best known within the great family of Northern Song celadon, made in various locations in Northern China, especially in the Shaanxi province. As in this case, the Yaozhou celadons are easily recognizable by the olive color of the glaze and the scratch decoration visible in transparency under the light layer of the glaze.
