In its form, color, and style of decoration, this handsome jar is representative of blue-and-white porcelain produced at court-patronized kilns in eighteenth-century Korea. It most likely was used as a wine jar. The calligraphic quality and minimalism of the underglaze cobalt-blue decoration, as well as the abundance of white space, are among the features that distinguish Korean blue-and-white porcelain—especially that dating from this period—from its contemporary equivalents in China, Japan, and Europe.
