很多人去北京旅游都会去故宫浏览一番，人们不仅会被奇伟的建筑物深深吸引，同时也会在摆放于各个宫殿前的大铜缸发出由衷的感慨。这些大铜缸虽没有珠宝玉器那样玲珑剔透，但它浑厚的体积，富丽的外表，铜大缸给每个参观者留下深刻的印象。这些铜缸都是明清时期铸造的，由当时清廷内务府营造司管理，按照规定摆放在庭院的宫殿前和后宫的东西长街上，这些铜缸制作工艺精美，外表富丽堂皇，不仅用来消防用以盛水的器皿，也是皇宫中陈设品。这些铜大缸大都是铁式青铜制成，也有极少的鎏金铜缸。大铜缸口径1.6米，每口约重3392公斤，小铜缸口径1.28米，每口约重2166公斤。每年到了冬天，铸铜铜大缸，宫中人员都要给缸套上棉套，并上覆缸盖，且还要在下边的石座内燃上炭火。这一切措施，都是为了防止缸中的水冻结成冰，给急需带来极大的不便。这把火，一般从10月份就开始，一直要到来年阳春三月天气转暖才撤火。汇丰铜雕厂生产各种故宫铜缸、铜大缸、寺庙铜大缸、铸铜大缸、黄铜大缸、青铜缸等，欢迎前来洽谈选购。

Many people will visit the Forbidden City when they travel to Beijing. People will not only be deeply attracted by the magnificent buildings, but also express their sincere feelings in the large copper tanks placed in front of each palace. Although these big copper jars are not as exquisite and transparent as jewels and jade, their thick volume and rich appearance impress every visitor. These bronze jars were cast in Ming and Qing Dynasties. They were managed by the Construction Department of the Qing government's interior office at that time. They were placed in the front of the palace and the east-west street of the rear palace according to the regulations. These bronze jars were made with exquisite workmanship and magnificent appearance. They were not only used for fire fighting, but also for display in the palace. Most of these copper vats are made of iron bronze, and there are very few gilded copper vats. The diameter of the large copper cylinder is 1.6m, and each port weighs about 3392kg. The diameter of the small copper cylinder is 1.28M, and each port weighs about 2166kg. Every year, in winter, when casting large copper cylinder, the palace staff should put cotton sleeve on the cylinder liner, cover the cylinder head, and burn carbon fire in the stone base below. All these measures are to prevent the water in the cylinder from freezing into ice, which brings great inconvenience to the urgent need. This fire, generally from October, will not be removed until the next spring and March when the weather turns warm.
