A column base, also known as a plinth stone, is a stone block placed on the foundation to support columns. In traditional Chinese brick-and-wood architecture, it serves to bear loads and prevent moisture, playing an irreplaceable role in preventing building collapse. The third volume of Li Jie's *Yingzao Fashi* (Treatise on Architectural Methods) from the Song Dynasty records: "Column bases have six names: first called chu, second called shuo, third called tu, fourth called kua, fifth called jian, sixth called bian; today they are called stone drums." Column bases come in many styles including drum-shaped, melon-shaped, vase-shaped, palace lantern-shaped, hexagonal, and sumeru pedestal types. The "Drum-Shaped Teapot" is a late-period work by Gu Jingzhou. The body imitates the form of a drum-shaped column base, with the shoulder circumference slightly wider than the base. The body tapers slightly and straightens as it converges toward the bottom, thus visually emphasizing the tension of the pot's shoulder. Both the neck and spout are straight in style, full of strength. The lid design is distinctive—based on a flat lid but slightly raised upward, causing the entire pot's center of gravity to shift slightly upward, increasing the sense of balance in the form. At the same time, the slightly raised lid gives the entire pot a sense of being inflated, full and dignified. The "Hard Flat Teapot" presents an overall characteristic of hardness and simplicity. Only one piece was made, demonstrating that this is a masterwork meticulously crafted by Gu Jingzhou.
