The image shows a black pottery filter on display in a museum. The filter is round and cylindrical in shape with a wide base and a narrow opening at the top. It appears to be made of a dark material, possibly clay or stone, and has a rough texture. The bowl is slightly tilted to the side, with a small opening on one side and a wider opening on the other side. There is a label on the bottom right corner of the filter that reads "Black pottery filters" in Chinese characters. The background is a plain beige wall.
