There are many kinds of faience tea sets. Of them, the blue and white porcelain tea set, especially that produced in Jingdezhen of Jiangxi Province, is the best and the most famous. In ancient China, black, blue, and green were all referred to as blue. Therefore, the meaning of blue and white was more extensive at that time. The great feature of blue and white porcelain is its blue and white grains. With the porcelain-making techniques getting better and better, new varieties of faience have appeared, including the Red in Blue and White Glaze and the Blue and White with Overglaze Colors.
