  • The Bronze Age: Mining, Smelting, Casting

    The Discovery of MetallurgyDiscovering BronzeEarly MiningSmeltingCastingImagine you lived during the late Stone Age, a time known as the Neolithic. One day, you find a shiny chunk of rock. You pick it up and take it home where you try to figure out what it is. You hit it with a hammer, expecting it to break like most of the rocks you know, but instead, you dent it. Well, that's something special! You hit it a few more times and find you can shape it into something else, maybe into a knife. You find the edge is sharper t在study上查看更多信息
