Fine white porcelain dish with blue and red underglaze decoration. This type of bichromy, obtained from copper oxide for the red, is rare because it requires talented craftmanship to avoide the blackening of the colour due to the high temperature. In this case the skillful mixing of the colored oxides, together with copper, made it possible to create pleasing chiaroscuro effects at clouds and tree foliage. Six-character Kangxi mark painted at the back.
