Blue and white porcelain
"Blue and white wares" (Chinese: 青花; pinyin: qīng-huā; literally "Blue flowers") designate white pottery and porcelain decorated under the glaze with a blue pigment, generally cobalt oxide. The decoration is commonly applied by hand, by stencilling or by transfer-printing, though other methods of application have also been used.
Origin and development 
The technique of cobalt blue decorations seems to have come from the Middle-East in the 9th century through decorative experimentation on white ware. Cobalt blue pigments were excavated from local mines in central Iran from the 9th century, and then were exported as a raw material to China.
The blue-and-white technique was fully developed in China with porcelain technology in the 14th century. On some occasions, Chinese blue and white wares also incorporated Islamic designs, as in the case of some Mamluk brass works which were converted into blue and white Chinese porcelain designs.
Tang and Song blue-and-white 
The first Chinese blue and white wares were as early as the ninth century in Henan province, China; although only shards have been discovered. Tang period blue-and-white is even rarer than Song blue-and-white and was unknown before 1985. The Tang pieces are not porcelain however, but rather earthenwares with greenish white slip, using cobalt blue pigments which probably originated in the Middle-East. The only three pieces of complete "Tang blue and white" in the world were recovered from Indonesian Belitung shipwreck in 1998 and later sold to Singapore.
14th century development 
In the early 14th century mass-production of fine, translucent, blue and white porcelain started at Jingdezhen, sometimes called the porcelain capital of China. This development was due to the combination of Chinese techniques and Islamic trade. The new ware was made possible by the export of cobalt from Persia (called Huihui qing, 回回青, "Islamic blue"), combined with the translucent white quality of Chinese porcelain. Cobalt blue was considered as a precious commodity, with a value about twice that of gold. Motifs also draw inspiration from Islamic decorations. A large portion of these blue-and-white wares was then shipped to Southwest-Asian markets through the Muslim traders based in Guangzhou.
Chinese blue and white porcelain was once-fired: after the porcelain body was dried, decorated with refined cobalt-blue pigment mixed with water and applied using a brush, coated with a clear glaze and fired at high temperature. From the 16th century, local sources of cobalt blue started to be developed, although Persian cobalt remained the most expensive. Production of blue and white wares has continued at Jingdezhen to this day. Blue and white porcelain made at Jingdezhen probably reached the height of its technical excellence during the reign of the Kangxi emperor of the Qing Dynasty (reigned 1661 to 1722).
Evolution of blue and white ware 
14th century 
The true development of blue and white ware in China started with the first half of the 14th century, when it progressively replaced the century-long tradition of bluish-white ware, or Qingbai. The main production center was in Jingdezhen, Jiangxi Province.

15th century 
With the advent of the Ming Dynasty in 1368, blue and white ware was shunned for a time by the Court, especially under the Hongwu and Yongle Emperors, as being too foreign in inspiration. Blue and white porcelain however came back to prominence with the Xuande Emperor, and again developed from that time on.

18th century 
In the 18th century export porcelain continued to be produced for the European markets. As a result of the work of Francois Xavier d'Entrecolles however, an early example of industrial spying in which the details of Chinese porcelain manufacture were transmitted to Europe, Chinese exports of porcelain soon shrank considerably, especially by the end of the reign of the Qianlong Emperor.
Influences on Islamic pottery 
Chinese blue and white ware became extremely popular in the Middle-East from the 14th century, where both Chinese and Islamic types coexisted.
From the 13th century, Chinese pictorial designs, such as flying cranes, dragons and lotus flowers also started to appear in the ceramic productions of the Near-East, especially in Syria and Egypt.
Chinese porcelain of the 14th or 15th century was transmitted to the Middle-East and the Near East, and especially to the Ottoman Empire either through gifts or through war booty. Chinese designs were extremely influential with the pottery manufacturers at Iznik, Turkey. The Ming "grape" design in particular was highly popular and was extensively reproduced under the Ottoman Empire.
Influences on European porcelains 
Early influences 
Chinese blue-and-white ware were copied in Europe from the 16th century, with the faience blue-and-white technique called alla porcelana. Soon after the first experiments to reproduce the material of Chinese blue-and-white porcelain were made with Medici porcelain. These early works seem to be mixing influences from Islamic as well as Chinese blue-and-white wares.

Direct Chinese imitations 
By the beginning of the 17th century Chinese blue and white porcelain was being exported directly to Europe. In the 17th and 18th centuries, Oriental blue and white porcelain was highly prized in Europe and America and sometimes enhanced by fine silver and gold mounts, it was collected by kings and princes.
The European manufacture of porcelain started at Meissen in Germany in 1707. The detailed secrets of Chinese hard-paste porcelain technique were transmitted to Europe through the efforts of the Jesuit Father Francois Xavier d'Entrecolles between 1712 and 1722.
The early wares were strongly influenced by Chinese and other Oriental porcelains and an early pattern was blue onion, which is still in production at the Meissen factory today. The first phase of the French porcelain was also strongly influenced by Chinese designs. Early English porcelain wares were also influenced by Chinese wares and when, for example, the production of porcelain started at Worcester, nearly forty years after Meissen, Oriental blue and white wares provided the inspiration for much of the decoration used. Hand-painted and transfer-printed wares were made at Worcester and at other early English factories in a style known as Chinoiserie. Many other European factories followed this trend. In Delft, Netherlands blue and white ceramics taking their designs from Chinese export porcelains made for the Dutch market were made in large numbers throughout the 17th Century. Blue and white Delftware was itself extensively copied by factories in other European countries, including England, where it is known as English Delftware.
The plate shown in the illustration (left) is decorated with the famous willow pattern and was probably made at a factory in the English county of Staffordshire. Such is the persistence of the willow pattern that it is difficult to date the piece shown with any precision; it is possibly quite recent but similar wares have been produced by English factories in huge numbers over long periods and are still being made today. The willow pattern, said to tell the sad story of a pair of star-crossed lovers, was an entirely European design, though one that was strongly influenced in style by design features borrowed from Chinese export porcelains of the 18th Century. The willow pattern was, in turn, copied by Chinese potters, but with the decoration hand painted rather than transfer-printed.
