Platinum - hard, refractory grayish-white metal

This was the platinum - severe, refractory grayish-white metal, very malleable, ductile enough. Platinum is much greater than the hardness of gold and silver. Platinum was mainly in dentistry - the printing fonts, crowns, fillings and false teeth. With the death of a man, this platinum fell into the grave, and for many years, disappeared from use of mankind. At the same time practical Americans even wanted to enter the law that the platinum was removed from the teeth deceased before the funeral. Platinum have done and are doing now jewelry. In the last century in South America discovered large deposits of platinum. Commencement of a regular "fever" seekers of happiness and wealth. Joint-stock companies, banks invest in new deposits huge amounts of money. Field stretched almost from the Cape of Good Hope to Northern Rhodesia. South African geologists tell us about the whole platinum belt, which stretches across America. It starts with this belt on the south coast and ends at the headwaters of the Nile. Somewhere in the depths of the Earth simmer for thousands and millions of tons of this metal.
