The distinctive blue color of the wares in this case was called "powder blue" by early Western collectors. The "powder" in the name did not refer to the color, but to the technique of applying the glaze in a powder form by blowing it through a bamboo tube onto the surface of the ceramic. During this process, the areas that were to remain white were covered, to be later painted with overglaze enamel colors.
