The 17th-century white porcelain with a grayish white color glaze revived by the first half of the 18th century, this time beginning to display a milky white tone. The beveling technique in particular made a remarkable development, which became one of the characteristics of this period. A mouth with a short neck, widely extended shoulder and the beveled octagonal body, all finely executed, are features of the first half of the 18th century. The interior of the mouth has a protruding stopper, suggesting that the jar originally had a lid. The jar was fired at one of the Gwangju official kilns, probably Kumsa-ri-type kiln.
