In winter, in order to prevent the water storage of "auspicious tank" from freezing, not only the cylinder head should be added, but also the work of "fumigation tank" should be carried out. The specific method is that a special "iron drawer" is set in the cylinder head to store carbon fire; at the same time, each cylinder is not directly placed on the ground, but at the bottom of the cylinder there is an arc-shaped stone base base, in which one arc-shaped stone is movable In this way, it is convenient to place the charcoal just below and place the implication and function of the copper cylinder to melt the frozen ice in the cylinder. This job has always been a "fire department" of the house of internal affairs, which decides when to start according to the seasonal climate changes, until the next year's hibernation.
Although the copper cylinder is not often seen, the large-scale pure Bronze Cylinder foundry, but in ancient times, it is a kind of common copper carving articles, which was first placed in the palace, mainly used for fire prevention. With its own characteristics, it has become a rare palace display, with high collection value. When visiting the Forbidden City and imitating the ancient palace museum, the price of the large and small copper VATS can't be missed. There are countless striking large VATS displayed around the palace. There are two kinds of big VATS: Copper vats and iron vats. According to the material, they can be divided into three types: "gold plated sea" copper vats, bronze vats and iron vats. According to historical records, in the middle of Qing Dynasty, there were 308 large and small tanks in the palace, but now there are only 108. The number of VATS and the size of the vats are determined by the environment. For example, all around Taihe hall, Baohe hall and Qianqing gate are decorated with "gilded sea" copper tanks, while the smaller bronze tanks or iron tanks are displayed in the courtyard of six palaces in the East and west of Neiting and on the long street.
