The lid and body of this covered box are each articulated with lobed ridges in the form of chrysanthemum petals, and a fine incised floral motif is rendered at the center of the lid. The glaze is a limpid, supple bisaek celadon of exceptional quality. Five traces of quartz kiln supports remain on the interior of the foot ring. The box is thought to have served as a container for incense or cosmetic powder. Its production is dated to approximately the mid-twelfth century, a attribution supported by close comparison with a celadon chrysanthemum-shaped covered box excavated from the royal tomb of King Injong — known as Jangreung — who passed away in 1146, which presents a strikingly similar form. Combining a luminous and supremely refined bisaek glaze with a composed and serene vessel form, this covered box is presumed to have been produced as a work of royal commission at the Sadang-ri kilns in Gangjin during the mid-twelfth century, at the very apex of Goryeo celadon production.
