This maebyeong (prunus vase) was created through a series of intensive production processes. First, the original celadon clay was delicately curved and shaped into the characteristic maebyeong form-- wide at the top and curving down into a more narrow foot. Then the vase was painted with iron-brown underglaze, and the leaf patterns were carefully carved and inlaid with white clay. Finally, a layer of glaze was applied to complete the vase. The technique of making inlay designs in underglaze iron first appeared in the early 12th century, but the method is so intricate and complex that it was rarely used. The full, curvilinear line of this maebyeong exudes elegance, while the vivid, natural brushstrokes of the white leaf design evince the vein of a leaf. The bold white strokes of the stems create a magnificent contrast with the dark color of the underglaze. This maebyeong presents a wealth of delicate aesthetics: the contrast of dark and light, the concise delineation of the leaves, and the masterful brushstrokes to apply the white clay. During firing, a refractory clay support was attached to the foot rim; fragments of vessels similar to this maebyeong were found at the kiln site in Sadang-ri, Daegu-myeon, Gangjin.
