Longquan celadon in the context of "Yuan Dynasty"

Chinese export porcelain includes a wide range of Chinese porcelain that was made (almost) exclusively for export to Europe and later to North America between the 16th and the 20th century. Whether wares made for non-Western markets are covered by the term depends on context. Chinese ceramics made mainly for export go back to the Tang dynasty if not earlier, though initially they may not be regarded as porcelain.

It is typically not used as a descriptive term for the much earlier wares that were produced to reflect Islamic taste and exported to the Middle East and Central Asia, though these were also very important, apparently driving the development of Chinese blue and white porcelain in the Yuan and Ming dynasties (see Chinese influences on Islamic pottery). Longquan celadon, which is mostly not porcelain on Western definitions, is one of the wares to produce large dishes that reflected Islamic dining habits, rather than the deeper bowls used by the Chinese. In general, wares made for export, especially in the early periods, were "mainly strong and rather roughly-finished articles", compared to those for the elite domestic market, to allow for the stresses of transport, and less sophisticated customers.

A resist, used in many areas of manufacturing and art, is something that is added to parts of an object to create a pattern by protecting these parts from being affected by a subsequent stage in the process. Often the resist is then removed.

For example in the resist dyeing of textiles, wax or a similar substance is added to places where the dye is not wanted. The wax will "resist" the dye, and after it is removed there will be a pattern in two colours. Batik, shibori and tie-dye are among many styles of resist dyeing.

Celadon (/ˈsɛlədɒn/) is a term for pottery denoting both wares glazed in the jade green celadon color, also known as greenware or "green ware" (the term specialists now tend to use), and a type of transparent glaze, often with small cracks, that was first used on greenware, but later used on other porcelains. Celadon originated in China, though the term is purely European, and notable kilns such as the Longquan kiln in Zhejiang province are renowned for their celadon glazes. Celadon production later spread to other parts of East Asia, such as Japan and Korea, as well as Southeast Asian countries, such as Thailand. Eventually, European potteries produced some pieces, but it was never a major element there. Finer pieces are in porcelain, but both the color and the glaze can be produced in stoneware and earthenware. Most of the earlier Longquan celadon is on the border of stoneware and porcelain, meeting the Chinese but not the European definitions of porcelain.

For many centuries, celadon wares were highly regarded by the Chinese imperial court, before being replaced in fashion by painted wares, especially the new blue and white porcelain under the Yuan dynasty. The similarity of the color to jade, traditionally the most highly valued material in China, was a large part of its attraction. Celadon continued to be produced in China at a lower level, often with a conscious sense of reviving older styles. In Korea, the celadon produced during Goryeo period (918–1392) are regarded as classic wares of Korean porcelain.
