What it means
The metal is abundant in the ground but bonded so tightly to oxygen that chemical methods could barely free it. In the eighteen fifties an aluminum bar was displayed beside the crown jewels in Paris, and Napoleon the Third is said to have reserved aluminum cutlery for his more important guests. An electrolytic process found in 1886 collapsed the price within a few years.
