An early Koryo dynasty celadon Maebyeong vase. 11th to early 12th century. The color is a more drab, vitreous green than the more opaque, bluer examples from the accomplished production of the middle 12th through early 13th centuries. Height, 10 1/2 inches (25.4 cm). Condition is good. Some oxidized kiln adherence to the sides and particularly the rim, inclusions in the glaze from the firing, a couple small unglazed points along the girth and foot, course foot with a couple old small chips on the foot only, partially glaze inside the foot - exposing an earthy light-brown body. Some traces of red enamel decoration (including some spots on the foot) no doubt added well after production but quite some time ago - now almost completely worn away.
