Bottom of a Chinese Gourd with Calligraphy Mark

This image primarily shows the bottom section of what appears to be a small, possibly decorative, object. The material is a tarnished brass or bronze alloy, displaying a rich, uneven patina with shades of gold, brown, and dark gray, indicative of age and handling. The central feature is a recessed circular area, within which a square-shaped inscription in traditional Chinese calligraphy is prominently displayed. The characters, from what is discernible, suggest a maker's mark or perhaps an auspicious phrase. The surrounding circular rim is raised and shows subtle concentric tooling marks, implying it was turned or cast. The outer edge of the object, partially visible, has a ridged or segmented pattern, suggesting the craftsmanship of the full item. This pattern could be wood grain, carving, or a textured metal design that continues around the body of the object. There are no obvious signs of significant damage such as cracks or major dents, but the surface exhibits a natural wear and oxidation consistent with an antique or vintage piece. The craftsmanship appears to be of good quality, with clear, albeit aged, inscription details. Given the context (Hulu gourd shaped with yin yang), this bottom piece is likely from a Chinese brass or bronze hulu, a traditional decorative and symbolic item. The calligraphy could provide key information regarding its origin, maker, or period, potentially linking it to the Qing dynasty or later, depending on the specific characters and style. The overall feel is one of an item that has been cherished and used, with the patina contributing to its aesthetic appeal and historical character.
