This rare antique Chinese Henan black-glazed jar, dating from the Jin to Yuan Dynasty (1115–1368 AD), is a magnificent example of northern Chinese stoneware. Characterized by its robust, balustre-style form, this piece features a lustrous, thick black glaze that stops short of the foot, revealing the buff-colored earthenware body beneath. The vessel is distinguished by its "oil spot" or russet-splashed decoration, where iron-rich brown spots have blossomed through the dark glaze during the firing process, creating a striking "starry sky" effect. Its classic silhouette includes a wide, rounded shoulder and a tapered lower body accented by subtle horizontal kiln-spun ribbing, a traditional technique that adds tactile depth and authentic character to the piece. This expertly crafted storage vessel represents the sophisticated ceramic artistry of the Henan kilns and would make a significant addition to any collection of early Chinese art. Weight is 962,2 gr. Height 16 cm. Width 15 cm.
