Bauxite discovered in France

In 1821, bauxite, an aluminium ore, was discovered in southern France near the village of Les Baux by Pierre Berthier. This hard, reddish, clay-like material contains about 50% hydrated aluminium oxide with impurities such iron oxide. It was named "beauxite," after the village, by P. A. Dufrenoy (1847), but changed to "bauxite" by E. H. Sainte-Claire Deville (1861). At first, it was so difficult to extract the metal, it was more valuable than gold. In 1855, a bar of aluminium was exhibited beside the Crown Jewels at the Paris Exhibition. The great abundance of the ore, and the discovery (1886) of refining using electricity independently by Charles Hall and Paul Louis Toussaint Heroult made the metal inexpensive.«

The nuns were happy to take whatever they were offered and returned to their car. As they were pouring the gasoline from the bedpan into the tank of their car, a minister drove by.
