This handcrafted, one-piece lost-wax cast vase by renowned Japanese bronze casting master Seiun from Takaoka features the classic long-necked, celestial-sphere vase shape. The vase utilizes a unique blue-green mineral enamel technique, with flowing gold-threaded patterns in varying shades of turquoise. The glaze has a warm, mirror-like finish, its texture resembling natural turquoise. The slender, tapering neck complements the full, rounded body, creating a balanced and harmonious silhouette. It comes with a matching paulownia wood box, the lid bearing Seiun's own calligraphy and two exclusive vermilion seals. The base is engraved with the artist's signature. The original wooden box is fully preserved. The vase is in excellent condition: the bronze body is cast in one piece, without dents, pinholes, cracks, or chips; the blue-green and gold enamel on the surface is complete and even, with no large areas of glaze loss or exposed bronze wear, only slight signs of age; the mouth and foot edges are intact and without chipping, and the artist's signature on the bottom is clear and complete.
