一、曾经当过金属中的贵族有这么一个故事,传说在古罗马,一天,一个陌生人去拜见罗马皇帝泰比里厄斯(Tiberius),献上一只金属杯子,杯子像银子一样闪闪发光,但是分量很轻。它是这个人从粘土中提炼出的新金属。但这个皇帝表面上表示感谢,心里却害怕这种光彩夺目的新金属会使他的金银财宝贬值,就下令把这位发明家斩了。从此,再也没有人动过提炼这种“危险金属”的念头,这种新金属就是现在大家非常熟悉的铝。在19世纪以前,铝被认为是一种稀罕的贵金属,价格比黄金还要贵。当一个欧洲君主买了一件有铝纽扣的衣服时,他就瞧不起那些买不起这种奢侈品的其他君主。而没有铝纽扣衣服的君主,又是多么渴望有朝一日自己也能穿上这种带铝纽扣的衣服。在法国拿破仑三世统治时期, The story of a nobleman who used to be a metal has been told that in ancient Rome one day a stranger went to visit the Roman Emperor Tiberius and presented a metal cup that gleamed like silver, But the weight is very light.
