在清代，宫中的铜缸是由内务府统一管理的。每天一早，内务府官员便命苏拉（杂役）从井内汲水，一担一担地把所有大缸灌满，以备防火之用。每年到了小雪季节，宫内的太监就要在铜缸外套上一层特制的棉套，上面再加上厚厚的缸盖。同时在铜缸下的汉白玉石基座里放置一盆炭火，并保证其昼夜不息地燃烧着。这样，通过双重保暖措施，防止缸内的存水结冰。保暖工作一直要到第二年的惊蛰时节才能结束，那时大地回春，气候已经逐渐转暖，太监们就会解去棉套，撤去炭火。为了保证宫中有足够的水源用于灭火，当时在宫中设置了许多大缸。据《大清会典》记载，宫中共有大缸308口。
In the Qing Dynasty, the copper VATS in the palace were managed by the house of internal affairs. Early in the morning, officials of the house of the interior ordered Sura (the factotum) to take water from the well and fill all the large VATS one by one for fire prevention. Every year in the light snow season, the eunuchs in the palace will coat the copper cylinder with a special cotton cover and a thick cylinder head. At the same time, a pot of charcoal fire was placed in the marble base under the copper cylinder, and it was kept burning day and night. In this way, the water stored in the cylinder is prevented from freezing by double thermal insulation measures. The work of keeping warm could not be finished until the next year when the spring came back and the climate was getting warmer. The eunuchs would take off their cotton jackets and remove the charcoal fire. In order to ensure that the palace has enough water for fire fighting, many large VATS were set up in the palace at that time. According to the "Qing Huidian", there are 308 large VATS in the palace.

但世事沧桑，由于各种原因，如今只剩下231口了。这些大缸共分为铁、铜和鎏金铜三种。一般来讲，铁缸是明代时铸造的；铜缸有明代的，也有清代的；鎏金铜缸则均是清代铸造的。其中，以铜缸居多，所以人们习惯地称宫中的大缸为铜缸。
But the world is changing. For various reasons, there are only 231 left. These vats are divided into iron, copper and gilded copper. Generally speaking, iron VATS were cast in Ming Dynasty; copper ones were made in Ming Dynasty and Qing Dynasty; gilded copper VATS were all cast in Qing Dynasty. Among them, most of them were copper vats, so people used to call the large VATS in the palace as copper vats.
