In Wikipedia. Blue and White Porcelain is described :
"Blue and white wares" (Chinese: 青花; pinyin: qīng-huā; literally: "Blue flowers") designate white pottery and porcelain decorated under the glaze with a blue pigment, generally cobalt oxide. The decoration is commonly applied by hand, by stencilling or by transfer-printing, though other methods of application have also been used.
