故宫里的铜缸用的材质是青铜铸造而成，表面采用鎏金工艺制作，黄金的价格非常高，皇帝也知道这一点，精打细算，一个好的皇帝也是厉行节俭,目的是为了巩固封建统治的。 从这个角度来说,皇帝道光:打卤面为皇后祝寿，道光帝的节俭,在他还是皇子的时候就已经表现出来了，汉朝初年的文帝、景帝(当然,刘邦这个痞子就算了) 国家也是持家过日子只是个装用品，所以故宫铜缸采用青铜铸造，皇上也好面子，讲摆场所以大缸里面铸铜表面鎏金制作。

The copper cylinder in the Forbidden City is made of bronze. The surface is made of gilded gold. The price of gold is very high. The emperor also knows this. He is careful and thrifty. The purpose of a good emperor is to consolidate the feudal rule. From this point of view, the Emperor Daoguang: to celebrate the empress's birthday with noodles made of bittern, Daoguang's frugality has been shown since he was the emperor's son. In the early years of the Han Dynasty, Emperor Wen and Emperor Jing (of course, Liu Bang, the ruffian, even though) the country is just a decoration, so the Bronze Cylinder of the Forbidden City is made of bronze, so the emperor is good at face, so the large cylinder is made of gold-plated copper surface.
