如果是现代工艺产出的铜炉，就不是越重越好。铜有好几种，紫铜、青铜、黄铜、白铜，除了紫铜为纯铜外，其他三种都是合金铜，要是不良商家在合金铜里面加入了比铜密度大的铅，就会明显增重，可以吸引买家的眼球，但怎么做的人都是没良心的傻子，因为铅是含毒的，长期把玩含铅的香炉会导致铅中毒。
If the copper furnace produced by modern technology is not the heavier the better. There are several kinds of copper, copper, bronze, brass, white copper, except that copper is pure copper, the other three are alloy copper. If bad businessmen add lead which is more dense than copper in the alloy copper, it will increase significantly and attract buyers'attention. But what to do is a conscientious fool, because lead is poisonous, long-term playing with lead-containing incense stove will lead poisoning.
