Swatow ware or Zhangzhou ware is a loose grouping of mainly late Ming dynasty Chinese export porcelain wares initially intended for the Southeast Asian market. The traditional name in the West arose because Swatow, or present-day Shantou, was the South Chinese port in Guangdong province from which the wares were thought to have been shipped. The many kilns were probably located all over the coastal region, but mostly near Zhangzhou, Pinghe County, Fujian, where several were excavated in the mid-1990s, which has clarified matters considerably.
Many authorities now prefer to call the wares Zhangzhou ware, as it seems that Swatow did not become an important export port until the 19th century, and the wares were actually probably exported from Yuegang, now Longhai City, Zhangzhou. The precise dates for the beginning and ending of production remain uncertain, but the evidence from archaeology suggests production between about 1575–1650, though an earlier start has been proposed. The peak levels of production may have ended around 1620.
Compared to contemporary Jingdezhen porcelain, Swatow ware is generally coarse, crudely potted and often under-fired. Decoration in underglaze blue and white using cobalt is the most common, and was probably the only type of decoration at first, but there are many polychrome wares, using red, green, turquoise, black and yellow overglaze enamels. Underglaze blue decoration had been common in Chinese ceramics for over two centuries, but polychrome enamels had been relatively unusual before this period. The pieces are mostly "large open forms such as dishes, painted with sketchy designs over the glaze in red, green, turquoise and black enamels". On the other hand, the "drawing has a spontaneity not found in the central tradition" of finer wares.
