What Is Gold Bar ( Video )

Gold is something with which we all are familiar. It is a metal, which changes life with its value. It makes business with what it is worth of and opens a completely new line of opportunities in financial sector. It indicates power, strength, and wealth. A possessor of this metal is looked upon with respect.

Moulding a metal in shape of bars is a common practice. Sometimes, it is for convenience in storage and sometimes for ease in shipment. In case of gold, it is mainly to store the metal, as gold being a precious metal, is usually not shipped in that huge quantities that is difficult to move as such. Therefore, as the name implies, a gold bar is a bar shaped piece of the metal, gold.

The gold bars, which are available are of different types, have different weights and thus different values. The procedure by which the gold bars are prepared or manufactured is the distinguishing factor in its different types. Mainly   gold  bars are manufactured using two different type of  methods , casting method or the minted method.

Casting the gold involves, at the very first, the purification of the gold and then its liquefaction. It is then poured into a mould, which is a hollow tank with a desired shaped cavity inside it. After pouring the liquid metal, the setup is left for a particular time, and is allowed to cool. The final step is to eject or break the metal, which in this case is gold, out as per the requirement.

The second major method of its formation is minting. Though mainly used for making coins, this  method  is also used for  gold . It involves cutting a gold piece in required dimensions by a piece of gold used as a tool. The markings on the gold bar are made from mechanical presses. We usually see gold bars in movies in the form of 400-ounce London goods delivery. These are quite famous and this is the very type held by many central banks. Its standard weight is 12.44 kilograms.

There is a certain mystery related to gold bars. The mystery finds its origin in China. It is not merely a story, but it indicates and highlights the importance of gold, its bars in human lives, and in their dealings related to money even in the past. It is said that seven gold bars were issued to a General named Wang, of Shenghai back in 1933.

After that, the bars became common and were to act as bank certificates as a return to money deposits. There are markings and words written on these gold bars but in a script, which is not recognised yet, thus making the use of the bars quite mysterious. However, by this mystery it became clear that gold bars in that time were used as a money exchange certificate.

Gold tola bars are common these days. This means that bars are weighed in tolas and are kept by governments all over the world in their central banks, indicating their wealth and power of their currency. Even locally, the people like investing their money in gold and purchase the bars. They like to keep them and sell these money carriers when their value maximises. This has become a profitable business.

What do we know about metallurgy? Metallurgy is branch of science that deals with the procedures used when extracting metals from ores, purifying and alloying them. This also involves the study of the procedures used when making objects out of metals. Yet, to be able to understand fully all about metallurgy, it would be better to have a short glimpse of the history of metallurgy.

One of the oldest processes of applied science is the process of metallurgy. Its history would give us a good view of how the process developed and its association with metals. The history of metallurgy occurred around 7,000 BC which what they call the age of copper. It is the period between the Stone Age and the Bronze Age which could also be considered the turning point between Stone to Metal. 

The first process was purely accidental when the copper enter into the fireplace campfire hot. Obviously, the copper melted and when it cooled people noticed the change of its shape. The development of the process was also contributed by the magic of the fire. We could learn from the history of metallurgy that people in the old days relied on the fire for the metal processing 

In the 2800 BC comes the Bronze Age which is another development in metallurgy. People have become brilliant that they made an alloy of copper and tin since both was commonly found in the same ore. Which results bronze and bronze has become a commodity was used for the weapons of the armies as well as used as money for trade. 

In the 1500 BC, another breakthrough was found in metallurgy. It is the discovery of iron which was considered the most abundant metal in the earth but was difficult to extract.

By this then, in the 11th century, people pushed their luck and tried to heat the iron with charcoal in such a way that the carbon from the charcoal can be transferred to the iron.

With this, the metal would be hardened and the Age of Steel came. Yet, iron has become a continuous challenge to most metallurgists since it’s very hard which can only be hammered but can’t be melted. In the 513 BC, Chinese were able to think of a furnace strong enough to heat iron.

Metals nowadays are a commodity. From the buildings, the houses, to the littlest tools we use everyday; the magic of metals is involved. Without them, everything wouldn’t be that easy. One after another, metals have developed and evolved. Over the years, people never stopped adding bits to the history of metallurgy making way for the metals to be obviously useful and one of the most important things in our daily lives nowadays.
