Hello, this item is a large Korean-style stoneware jar, most plausibly inspired by Buncheong ware traditions, but best classified as a later 20th-century Korean or Korean-influenced studio stoneware vessel rather than an authentic Joseon-period Buncheong example. The jar stands approximately 18 inches tall and is notably heavy, with thick walls and a dense ceramic body. The surface shows a blue-green celadon-toned glaze with incised and carved decoration beneath, forming abstracted cloud or wave-like motifs. While Buncheong wares of the 15th to 16th century are typically characterized by slip decoration, brushed white engobe, and a more spontaneous aesthetic, this vessel displays a more uniform glaze application, controlled symmetry, and a carefully finished foot, all of which point to a modern studio production drawing on historical Korean ceramic language rather than a period piece. The absence of kiln scars typical of early Buncheong and the regularity of the base further support a modern date.

The condition is very good, with no visible cracks, restorations, or major chips, and only minor surface irregularities consistent with studio-fired stoneware. Comparable large Korean or Korean-style studio stoneware vessels from the late 20th century, especially those produced without a known or documented master potter attribution, generally trade on the secondary market between USD 700 and USD 1,400, depending on scale, glaze quality, and decorative appeal.
