Blue-white porcelain
Drawing the design with a cobalt pigment onto the stoneware body and painting over it with a transparent glaze creates the blue-white style, also known as "underglazed blue". The piece is then fired at a high temperature. Blue-white porcelain was introduced during theYuan Dynasty(1271-1368) and has been in production ever since thanks to its bright colors, simple yet elegant patterns, and smooth glaze that never fades.
The Yuan Dynasty is a key period for the development of the firing techniques for blue-white porcelain in China. Its unique characteristics were based on the techniques of former dynasties.Blue-white porcelain had become a major porcelain product in China by the Ming (1368-1644) and Qing dynasties (1644-1911).
Blue-white porcelain of the Yuan Dynasty is large, with a thick roughcast. Generally, the works include big bottles, pots, bowls and plates, with the traditional flavor of the Tang (618-907) and Song (960-1279) dynasties. Due to the underdeveloped techniques, there are two interfaces on the body and several veins inside the body. The roughcast is not as smooth as that of the Ming and Qing dynasties and the glaze is thicker due to more iron in the raw glaze materials.
