Chenghua color is refined and very distinct and this is one reason why Chenghua blue and white is so easy to identify. Some are only concerned how the Chenghua mark is written and do not emphasize enough about the color and tone of the imported cobalt and the painting style. These are the most important things to authenticate Chenghua Blue and White because this cannot be duplicated. The sumali / smalt cobalt alone would run uncontrollably and had to be mixed with Chinese domestic pitang / pingdeng cobalt to stabilize it. Not until the Chenghua period did the potters gain complete control over sumali / smalt imported cobalt. The Chenghua potters were capable of painting details as thin as a hair in a free style with motion and flare. Some say the sumali / smalt imported cobalt was not used after the 15th century. This is not correct there are some pieces that used this cobalt in the early 16th century. Very few photographs capture the different cobalt colors correctly in the book by He Li Chinese Ceramics plate 409 and Sotheby book 30 years in Hong Kong plate 245, the strong blue color and tone are good examples of the color and tone when the two cobalt's were mixed together.
