Gold is a natural forming metal in which its natural state offers an unequalled stability and beauty. Moreover, its malleability permits to manufacture of almost transparently thin leaves, while from one ounce of gold it is possible to draw a fine wire of fifty miles long. The ductility of gold diminishes in relation to the amount of other metals alloyed with it. Its melting point is between 1832 and 1940 F; it is not subject to normal oxidization and is insoluble in nearly all common acids. The density of gold is about 19.3 times the weight of an equal volume of water and about 3 times of an Iron in the same size.
Although present in very short measure in almost all rocks, in the sea and rivers, in sand and even in plants, the areas which are rich in gold are few and scattered throughout the world. Mainly it comes from the deepest recesses of the earth and is probably the first known to man. Layers of gold are easy to reach near the earth’s surface. By mining process it will come out from earth. Raw gold is known as ‘Nugget’, & the gold found from river beds called ‘Alluvial’.
Gold was first found in India (when it’s called Hindustan), before millions of years ago. There is no proper history available for the mining of gold, but before more than 10000 million years ago the Indians were familiar with gold. The Indians introduced the entire world about the art of jewellery, metals & metal working. As the world history first use of gold had been traced back to 4000 years B.C. The Egyptians and Romans are developed gold fever, using it for coins & jewellery ornamentation. No more earliest history of any culture, that says they knew about gold before more than 4000 years. But as Indian history before millions of years ago Indians were had gold coins (called Suvarna Mudrica or Sona-Mohar), exclusive gold jewelleries and gold utensils.
