The History Of Gold
Gold was discovered in the form of shining, yellow nuggets for the first time. “Gold is found where it is sought after,” as the saying goes, & gold was found in its natural state in streams over the world when it was first discovered.
It is without a doubt the first metal that early hominids came into contact with.
Gold became a part of all human culture as time progressed. Working and playing with it was made more enjoyable because of its natural beauty, brilliance, and lustre, as well as its great malleability & resistance to tarnish.
What Is The Origin Of Gold?
Because gold is widely dispersed all through the geologic world, its own discovery occurred to a diverse range of groups in a diverse range of geographical locations.
And nearly everyone who discovered that was impressed with it, as the developing culture that they were living at the time of discovery.
As far as, gold was the first metal that humans were aware of. Iron and copper-working are considered the most significant technological advancements in human history, although gold came first.
Gold is the most straightforward of metals to work with. It is found in the virtually pure & workable state, whereas the majority of other metals are found in ore-bodies which are difficult to smelt and are therefore less valuable.
Gold’s earliest applications were almost certainly ornamental, & its brilliance and durability made it associated with deities & royalty in ancient civilizations.
Gold was always considered to be a powerful substance. Although, lost track of the earliest recorded history of human interactions with gold, its association with immortality, with gods, and with wealth itself is common to many cultures around the world.
Gold Was Used In A Variety Of Ways In The Ancient World.
Due to the fact that gold is commonly found in its native form, i.e., without being combined with the other elements, and that it is beautiful & imperishable, gold was among the 1st metals to be mined.
Additionally, gold can be used to create exquisite objects. Ancient civilizations lavished gold on their tombs and temples, & gold artefacts dating back more than five thousand years have been discovered in Egypt, indicating that gold was used in abundance by their artisans.
The gold items found in the tomb of Tutankhamun by Howard Carter & Lord Carnarvon in 1922, which are particularly noteworthy, are also noteworthy.
Egypt was ruled by this young pharaoh during the 14th century. Around 6 million people saw the “Treasures of Tutankhamun” display, which featured some of these artefacts, when it toured the United States from 1977 to 1979.
Gold figurines, diadems, masks, cups, and jewelry, as well as hundreds of adorned beads and buttons, were found in the graves of aristocrats just at the ancient citadel of Mycenae Greece, by Heinrich in 1876. Over 3,500 years ago, skilled artisans crafted these beautiful works of art.
Properties Of Gold
Because it doesn’t oxidize under normal conditions, gold is referred to as a “noble” metal. The chemical symbol Au has been derived from a Latin word “aurum,” which means “golden egg.”
Pure gold has a metallic lustre and is sun yellow, but it can be colored by combining it with various other metals, like silver, palladium, tellurium, copper, nickel, platinum, and iron.
These combinations result in a variety of color hues generally ranging from silver white to green & orange red when gold is mixed with the other metals.
Pure gold has a hardness similar to that of a penny, making it a relatively soft metal. It is the metal with the greatest malleability and ductility.
The specific gravity, or density, of pure gold seems to be 19.3, whereas mercury has a specific gravity of 14.0 and lead has a density of 11.4 respectively.
Impure gold, as it is found in deposits, has the density of sixteen to eighteen, while the waste rock (gangue) that comes with it has the density of around 2.5.
In order to separate gold from clay, clay, silt, sand and gravel in the sand, gold pans, rocks, and sluice boxes can be used to move it around and get it out of there.
