Among various kinds of faience teawares, blue and white porcelains attract the most attention. They refer to the patterns made directly in the porcelain bases and added a layer of transparent glaze with oxidized cobalt as colorant. They will be deoxidized about 1300℃ and then the porcelain will be completed. Blue and white patterns set each other off, simple but elegant. Since the pattern is made over the glaze, it looks brighter, which also adds charm to blue and white porcelain teawares.
