This is a sweet little water coupe with the lovely soft blue glaze color that distinguishes Qingbai ceramics. It measures 2 3/8" diameter at the top - 3 1/2" diameter at the widest - 2½ " diameter at the base and is1 2 1/2" high. It is in generally good condition. We believe that the top has been ground down for some reason some time in the past. We very much believe that the coupe could be from the Song dynasty based on the clay and the glaze. There are some indications that the glaze has been degraded somewhat from burial. However, there have been so many reproductions and copies made over the years that we are going to be conservative and date it to the Late Qing dynasty, 19th century.
Qingbai (bluish white) ware is a type of pottery made in the Song Dynasty (960-1279) that has a bluish tint to it. It is also referred to as Yingqing (shadow blue) ware in modern times. It is made using a specific type of porcelain and then adding a tinted glaze over the white porcelain. Much of Qingbai ware was used by the common people, which is very rare for this time period. A great deal of the pottery that was made at this time period was made strictly for imperial use.
The Qingbai ware achieved true translucency through using kaolin and fine-grained porcelain stone that supported thin walled vessels. The high point of Qingbai ware was between the 10th and 13th centuries. This accomplishment was achieved in the province of southeast Jiangxi in the town of Jingdezhen.
After creating the chemical achievement that supported the thin vessels the next aspect to master was the glaze. This type of smooth, glassy glaze is achieved by using a small amount of iron in a reduction-fired kiln. This type of glaze then achieved a bluish green tint. Qingbai ware has a pure white porcelain body with a bluish tinted glaze.
Qingbai initially appearing in the Northern Song period from about 960-1127 and then became a popular item in the Chinese market. They gained their widespread important popularity during the Southern Song period, which lasted from around 1127-1279. They were also widely exported to Chinaï¿½s neighboring nations.
