The production of copper carving generally goes through several important processes, such as metal smelting, forging, carving, gilding, polishing and scarlet. The process is complex, the price of copper cylinder is high, and the process is also very exquisite. Casting methods there are two main casting methods of copper sculpture, namely wax loss and mold method.

失蜡法：用蜡制成模，外敷造型材料，成为整体铸型。模具法：运用广泛，大型铜雕一般都要经过分件浇铸，然后衔接成一个整体。熔铜法：运用无模可控熔铸工艺，铸铜大缸，“无模”使铜液自然流畅而解形；“可控”使铜液在艺术家掌控中熔意。铸造法：运用无模可控熔铸工艺，“无模”使铜液自然流畅而解形；“可控”使铜液在Lost wax method: make a mold with wax and apply molding materials to form a whole mold. Mold method: it is widely used. Large copper carvings are usually cast in parts and then connected into a whole. Copper melting method: the use of mold free controllable casting process, casting copper cylinder, "mold free" to make the copper liquid natural and smooth solution“ "Controllable" makes molten copper melt in the control of artists. Casting method: the mould free controllable casting process is used to make the liquid copper flow naturally and dissolve“ "Controllable" makes molten copper melt in the control of artists.艺术家掌控中熔意。

很多人好奇它是如何保证一年四季都有水的，如果冬天结冰了怎么办呢？北京虽然寒冷，但结冰的时间也不会很长，如果缸里的水结冰，人们会在缸下生火来使冰块融化。很多人会认为这种方法十分愚蠢，但是以古人的眼光来看，这种超前的安全意识已经让我们感到惊叹了。
