人类最早使用铸造金属的记载已经模糊不清了,但我们可以这样推测:早期的狩猎者们围坐在火边,一块铜块落进了煤炭里,铜块熔化并流淌,像一股闪光的小溪流,一旦冷却,这个闪光的重物体就变得很硬,形成了新的形状。 很可能早期人们看到这种现象反复发生,然后他们寻找、收集铜块,把它们扔到火里,看那些闪光的溪流慢慢流出。一些人想象并在沙地上面出一个形状,让金属流进去,也许就变成了一个矛尖。从那以后,金属铸造经历了几十个世纪直到今天。
The earliest use of cast metal records has been blurred, but we can surmise that early hunters sat around the fire, a piece of copper fell into coal, copper melting and flowing, like a flash of the stream, once cooled, heavy body of the flash becomes very hard the formation of a new shape. It is very likely that people saw this phenomenon happen again and again in the early days. Then they looked for and collected copper blocks, threw them into the fire, and watched the gleaming streams flow slowly. Some people think it is a shape in the sand above, let the metal flow into it, may become a spear. Since then, metal casting has gone through several decades until today.
