      "text": "Blue and white pottery (Chinese: 青花瓷, qīnghuā cí) is ceramic ware decorated with cobalt-blue designs painted on a white body and covered with a transparent glaze. It is most closely associated with porcelain made at Jingdezhen in Jiangxi province, China, but the technique spread across Asia, the Islamic world and Europe, and it became one of the most widely traded ceramic styles in history."

    {
      "heading": "Technique and materials",
      "text": "Blue and white is an underglaze technique. Cobalt pigment is painted onto the unglazed or lightly dried body, a clear glaze is applied over it, and the piece is fired at high temperature. The cobalt therefore fixes permanently beneath the glaze, which gives the decoration its characteristic softness and resistance to wear. The white ground depends on a fine, high-fired body, which in China was made from kaolin-rich clays and fine stone. Early Chinese cobalt was often mixed with other materials, and its colour varied with the ore used and the firing conditions.\n\nCobalt was the decisive material. Early pieces used cobalt that was imported, probably in cake form, from Iran and was ground into pigment before painting. Later, Chinese potters found and used domestic cobalt ores, and the balance between imported and native pigments shaped the colour of each period. The change in colour from bright, deep blue to a greyer tone in some later Ming wares is usually linked to this shift in supply."

      "heading": "Origins in the Tang dynasty",
      "text": "Cobalt was used to decorate ceramics in China during the Tang dynasty (618–907). Stoneware with underglaze cobalt decoration was among the cargo recovered from the Belitung shipwreck, which dates to about 830 and was carrying goods toward the Middle East. Blue-and-white stonewares from the Baihe kiln site in Gongyi, Henan, are often described as the earliest high-fired Chinese ceramics painted in cobalt blue. These early wares were technically different from the later Jingdezhen porcelain and did not lead to a sustained tradition, so their place in the lineage is treated with caution."

      "heading": "The Yuan dynasty and the Persian cobalt trade",
      "text": "The decisive development came under the Yuan dynasty (1271–1368), when the Mongol Empire linked China and Persia within a single political system. Persian cobalt, known in Chinese as huihui qing (回回青, \"Muslim blue\"), was imported in quantity and used to paint white porcelain at Jingdezhen from the early 14th century. Yuan blue-and-white was exported along maritime and overland routes, including the Silk Road, to the Middle East and Southeast Asia, where it was highly valued. Many of these pieces reflected the aesthetic preferences of buyers in Islamic markets, including geometric motifs and, in some cases, inscriptions."

    {
      "heading": "The Ming dynasty",
      "text": "Blue and white became the most prized type of porcelain under the Ming dynasty (1368–1644). Early Ming potters continued to use imported Persian cobalt, but local cobalt ores came into use during the Xuande period (1426–1435), which made the Ming court less dependent on imports. Xuande-period wares are often regarded as a classic phase, featuring dragons, phoenixes, cranes and sea creatures, along with designs such as the Three Friends of Winter. Under the Hongwu emperor, the style became more sinicised and moved away from the densely decorated Yuan pieces.\n\nLater in the dynasty, the decline of Central Asian trade reduced the supply of good imported cobalt, and the quality of some mass-produced wares fell as output rose. The Ming imperial kilns at Jingdezhen nevertheless remained the leading centre of production, and their wares were used both at court and for export."

    {
      "heading": "The Qing dynasty",
      "text": "Production continued and expanded under the Qing dynasty (1644–1912). The Kangxi reign (1662–1722) is often described as a second peak of the style, with technically refined pieces and a wide range of forms. Scientific studies of Qing blue-and-white from Jingdezhen, covering the Kangxi, Yongzheng and Qianlong reigns, have examined the sources of cobalt used in this period. Qing wares were made both for the court and for a large commercial market, and they remained the mainstay of Chinese porcelain exports."

      "heading": "Export and global influence",
      "text": "Blue and white was one of the most widely traded ceramics of the premodern world. For Middle Eastern buyers, Jingdezhen workshops produced large dishes with densely packed geometric patterns inspired by Islamic metalwork and architecture. Some pieces carried Arabic or Persian inscriptions, which reflected the consumption of such wares among Muslim elites and the long-standing commerce between China and the Islamic world.\n\nEuropean demand grew after the arrival of Portuguese and other maritime traders in the sixteenth century, and some wares were produced with European heraldry for overseas clients. Blue-and-white porcelain strongly influenced European ceramics, including Delftware in the Netherlands and early European porcelain manufactories. In Japan, the style inspired Arita and Imari wares, and it also shaped the Korean and Vietnamese traditions, as well as Iznik pottery in the Ottoman lands and later ceramics in India."

      "heading": "Cobalt sources and scholarly debates",
      "text": "Several questions about blue and white remain under discussion. The first concerns chronology. Some archaeologists regard the Tang wares as the true beginning of the tradition, while others date its mature development at Jingdezhen to the late Yuan period, because the Tang wares show little continuity with later production. The second concerns cobalt provenance. Historical texts associate Ming cobalt with ores from Zhejiang, but analyses of Qing material have pointed to a closer match with cobalt from Yunnan. Analyses of Yuan and early Ming pieces have identified Persian cobalt by its mineral composition, though some scholars argue that certain Yuan and Ming wares may have been made locally in response to Chinese models."

      "heading": "Legacy",
      "text": "Blue and white is a central subject in the study of Chinese ceramics and of cross-cultural exchange in the premodern world. Its designs, which range from imperial dragons to landscapes, reflect the values of successive dynasties and the tastes of the markets it served. Museum collections in China, Europe, the Middle East and elsewhere hold large holdings of Yuan, Ming and Qing pieces, and the style remains a symbol of Chinese craftsmanship."
