The copper kettle has a straight mouth, a bulging belly, a flat bottom, and a plain surface. It is a practical device. The maximum diameter of the abdomen is below the shoulder and there are two ring-shaped ears. It was unearthed in the second room on the west. When it was unearthed, the kettle was filled with clear water. There seemed to be a scoop in the water. When it was moved, the scoop disappeared. The scoop in the kettle may be the water scoop placed at that time. After more than two thousand years, the water scoop has decayed. The kettle is a cooker, which should have evolved from the urn. This kettle is the same as the bathing utensil. When it is a bathing utensil, it is used for boiling water.
