Tongtie Vat Review

The copper iron cylinder is one of the representatives of the Forbidden City, which can be seen everywhere in the Forbidden City. In ancient China, the waterproof of the house is the first place, especially the national buildings such as the Forbidden City.

The capacity of the copper iron cylinder is very large, which is an important tool for suppressing fire. In winter, the Beijing air drying materials are dry and the water is condensed into ice. According to the practice in the palace, each large cylinder is equipped with charcoal fire, and the water is constantly distributed, which can both keep warm and prevent fire.

故宫里面，铁质的大缸是明朝遗留下来的 ， 铜制的是清朝遗留下来的 ， 镏金大缸上还有八国联军时留下的刮痕，现在依然可见。

在故宫里，一共有铜铁缸，300多口，分布在各个角落，这些铁缸有明朝的，有清朝的，明朝的比较简约，清朝的两侧镶嵌对称的兽头。

铜铁缸其实在故宫内部有好几个，分布于多处。这个在当时是用来储水以防火灾的，是一个消防设备。不过目前再来看，其精美的做工更具欣赏价值，可以停下脚步欣赏一番
