Vintage Blue and White Porcelain Chinese Soy Sauce Jar

This item is a vintage Chinese porcelain lidded condiment jar, traditionally used for soy sauce or similar liquids. It features a tapered cylindrical body with molded rope-like texturing around the upper rim and base, simulating the appearance of a traditional woven basket or barrel. The piece is crafted from white porcelain and features underglaze cobalt blue hand-painted calligraphy and markings. The central character '上' (shang) is prominently displayed within a square border, often signifying 'superior' or 'high quality.' Flanking this are smaller inscriptions indicating 'Registered Trademark' and 'Soy Sauce.' The lid is dome-shaped with a central knob and two decorative loop handles styled like stylized feet or animals. The overall height is approximately 5 to 6 inches. Its condition appears fair to good for its age, with visible surface grime, minor pitting in the glaze, and some light brownish discoloration or patina near the top shoulder. There are no immediate large cracks visible, though tiny kiln firing flaws are present, which are characteristic of mass-produced mid-20th-century export ceramics. The craftsmanship reflects a utilitarian folk-art style rather than fine imperial porcelain, typical of the Republic period or early People's Republic of China era.
