Though there is some controversy about this, it is thought that porcelain was inventedabout the timeoftheEasternHanEmpire. It is thought that the first porcelain was made by firing the ceramic materials to the necessary temperature. By so doing, they made a kind of light but strong ceramic that was preferable for artistic and decorative purposes, and it has been in high demand ever since.
Recent archeological finds of porcelain pieces in Han-era sites show that porcelain was produced in the Han Empire, but not much is known about their porcelain production. It is known that celadon wares (greenish porcelain) with beautiful hues were produced in the Shangyu area in Zhejiang Province south of the Yangtze River. It is said that the Yue kilns of Shangyu made the area one of the major and foremost centers of celadon production then.
The Han Dynasty collapsed in 220 AD, and shorter-lived and regional empires arose and fell during the ThreeKingdoms period, the JinDynasty, and the SuiDynasty. Celadon porcelain production continued in the Shangyu area south of the Yangtze River, and in the north in Henan Province and Hebei Province a more translucent variety of porcelain was produced.
Then the next long-lived dynastic empire arose called the TangDynasty. Two things spurred the production and export of porcelain in the Tang Empire. Tea drinking became popular, and this necessitated the production of much durable and beautiful teaware.
Two major types of porcelain were recognized in the empire. The Xing porcelain in the north in Hebei Province gained fame both in the empire and in the West during the mid-Tang Dynasty. It is believed that Xing porcelain was produced in the counties of Lincheng, Neiqiu and Xingtai. Their white porcelain became a standard of Tang porcelain because it was known for its white color and hardness.
The other favorite porcelain was celadon that varied in shade from jade green to bluish green. The Yue area in Zhejiang was still known for its production of jade-like celadon porcelain.
After the Battle of Talas in 751, the Tang Empire lost control of the Silk Road trade routes, but Middle-Eastern people ruled Central Asia and became directly involved in extensive Silk Road trade. In 851, a traveler named Suleiman was in the Tang Empire in 851. He wrote:
“ They have in China a very fine clay with which they make vases which are astransparent as glass; water is seen through them. The vases are made of clay. ”
One of the first SongDynasty emperors named Zhenzong selected Jingdezhen in Jiangxi Province to be an imperial porcelain production center in the year 1004. It remained the main imperial production center for about 900 years until the end of the Qing era.
What made this town so famous was in part the quality and quality of extensive kaolin depositsfound near the town. There was a hill where kaolin was extracted. The hill is tall so that is how kaolin clay got its name. “Kow” or gao means tall and “ling” means hill so this is how “kaolin” got its name.
Jingdezhen was at first famous for white porcelain, but by the addition of cobalt, a blue colored porcelain was also produced. It is thought that cobalt for blue colors was introduced from the Middle East, and blue and white porcelain was highly prized there. The Moslem world was the biggest Western market, and the porcelain reached there by sea routes since the Silk Road was closed off.
Meanwhile, the Yue celadon green porcelain of Zhejiang continued to be a favorite also.
The Mongols defeated the Song Empire and created the YuanEmpire. They reopened Silk Road trade. The blue and white porcelain of Jingdezhen was further refined and continued to be a favorite porcelain in the empire, and it was exported as well. Jingdezhen was the imperial pottery center.
In the MingEmpire, Jingdezhen continued to be a production center for blue and white porcelain. But during this era, there was a technical innovation in that manganese was added to prevent cobalt from bleeding during furnace heating and so distorting the fine artwork. For this reason, the Jingdezhen Ming Dynasty blue and white porcelain is considered to be the pinnacle of beauty and exquisite artwork on this type of porcelain.
The Ming Dynasty rulers prefered Dehua porcelain of Fujian Province for ritualistic and religious uses. A dynastic law specified that idols and ritualistic objects used in shrines and temples should be made of white porcelain. The Ming people preferred the the distinctive warm ivory-white porcelain that the Dehua area produced. The ivory color is produced because the clay there contains a trace of iron.
Dehua is near Quanzhou that had long been a principal port, and the area’s seafaring merchants helped to bring Dehua porcelain to Europewhere the French called it “blanc de Chine.” The white porcelain was popular in Europe as was the blue and white porcelain from Jingdezhen.
About the year 1603, some Dutch people captured Portuguese cargo ships bearing thousands of pieces of Ming porcelain. These were auctioned, and this ignited aporcelain mania in Europe. Pieces of porcelain were sold at such high prices that porcelain was known as “white gold.”
The Manchu conquest of the Ming Dynasty and continuing wars along the coast temporarily disrupted porcelain production and export. But EmperKangxi reorganized the production at Jingdezhen and the dynasty’s export trade. His court administration carefully supervised the imperial porcelain factory at Jingdezhen.
During his reign, personalized or specially ordered porcelain art became popular in America and Europe. Rulers, rich people, and merchants sent portraits, designs, coats of arms, statues, and articles to the Qing merchants that they wanted reproduced. The finished articles were prized.
After the middle 1700s, the Europeans had learned to make good quality porcelain, but the porcelain of Jingdezhen was still appreciated for its high quality and relatively lower cost until the end of the Qing Dynasty and for a few years afterwards. Jingdezhen was a huge porcelain production center, and the price of labor was lower there than in Europe.
