铜炉和兵器不同，不能用油。要火养。在炉内铺上香灰，然后放烧红的木炭（不能是明火的），就行了。
Copper stoves are different from weapons and cannot use oil. Keep it on fire. Put incense on the stove and then put red charcoal (it can't be an open fire), that's all.
但关键是温度控制，不能太热，最好是手摸上去非常烫但是还不至于起泡这样，保持这个温度，时间越长越好，如果说难控制宁愿它温度低点也不能高了，因为太高容易退火，那就很麻烦了。
But the key is temperature control, not too hot, it's better to feel very hot but not foaming. Keep this temperature as long as possible. If it's difficult to control, it's better to keep it low and not high, because it's too high and easy to annealing, which is very troublesome.
在这个期间不断用厚布搽拭，这样能得到好的皮色。铜炉要经常烧香，或者用木炭养护，不要放在潮湿的地方，这样包浆会越来越好。以上的方法也适用于铜香蕈。
