人类在创造物质文明过程中,铜是最先被人们所发现和最早为人们所使用的金属,只是从世界范围说,这种最早发现的铜一般是指红铜,即自然铜,也称纯铜,因为在自然界中较容易找到天然的红铜矿石,而且这种自然铜的硬度较低,其布氏硬度仅35°,只要直接捶打就可成不同的器形。红铜的含铜量高达98%至99%,表面有着红色的金属光泽。考古学家一般将这种最早出现的红铜器称作早期铜器,在使用早期铜器的同时,人类还较普遍使用着石器,而且石器还占有绝对的优势,故考古学家称这一时期为
Human beings in the process of creating material civilization, copper was first discovered by people and the first people to use the metal, but from the world said that this first discovered copper generally refers to copper, copper, also known as pure Copper, because natural red copper ore is easier to find in nature, and this natural copper has a lower hardness and a Brinell hardness of only 35 °, can be shaped differently by simply tapping it. Copper content of copper up to 98% to 99%, the surface has a red metallic luster. Archeologists generally refer to this first-emerging red bronze ware as an early bronze ware. While using early bronze ware, it is still more common for humans to use stone tools, and the stone tools still have the absolute advantage that archaeologists call this Period is
