“《中国古代冶金技术的成就》,不晓得是不是浮夸的哦~嘿嘿!”
报告zd版主。当然是浮夸的哦,典型的夜郎自大, 关起门来不看外面,当然都是世界第一咯。
我提几点供大家思考。
1. 既然《天工开物》称之为“ 倭铅”,比较合理的解释是指倭国来的铅。
把“ 倭铅”称为“我国是世界上最早冶炼并使用了金属锌的国家”有可笑的地方。
2. 简略摘要: 古印度有开采冶炼锌矿的历史(公元前1300–1000), 在以色列发掘出过公元前1400–1000 的黄铜器皿。 在特兰西瓦尼亚出土过含有87%锌的史前的制品。在瑞士伯尔尼,发现过罗马高卢时期的有高卢铭文的锌牌。 有图 “”
印度在1200年使用陶罐还原法提炼单质金属锌,从12世纪到16世纪生产了100万吨以上的金属锌。
In ancient India the production of zinc metal was very common. Many mine sites of Zawar Mines, near Udaipur, Rajasthan, were active even during 1300–1000 BC.
Zinc alloys have been used for centuries, as brass goods dating to 1400–1000 BC have been found in Israel and zinc objects with 87% zinc have been found in prehistoric Transylvania. Because of the low boiling point and high chemical reactivity of this metal (isolated zinc would tend to go up the chimney rather than be captured), the true nature of this metal was not understood in ancient times.
Smelting and extraction of impure forms of zinc was accomplished around 1200 AD in India.
3. 加上我的集币经验,希腊罗马的铜锌黄铜币是最普通的东东,日常用品。中国明以前的黄铜东东,凤毛麟角,我还没见过可靠的实物,或报道。
总之,宣称什么最好要有实证,那段红字确实非常可笑。
