This white porcelain jar from the mid-17th century is widely admired for its attractively voluminous body decorated with a dragon and cloud design in iron underglaze, the dynamic brush strokes, and the bold shaping. The main design, consisting of a dragon playing with a magic pearl amid the clouds, is accompanied by various subsidiary motifs including a scroll design around the mouth and an Anuruddha head design on the shoulder. While it shares certain traits with white porcelain jars with an iron underglaze design produced in the government-run kilns in Gwangju, the comparatively low quality of the clay and glaze suggests that it was made at a private kiln outside the capital area.
