Kathmandu. There are about 95 known metals in the world, from iron, copper, aluminum to rare platinum. But for thousands of years, in every civilization, gold and silver have been the only symbols of value, beauty, and wealth. <\/p>\n
They were worshiped as gods in Egypt, Rome, India and China. Jewelry was made, coins were made. Even today, there is a high demand for gold and silver at weddings. They are considered to be the safest investments. What is so special about these two metals that there are no other 93 metals? <\/p>\n
The biggest reason is science. Gold and silver are called great metals. That is, they do not react easily to air, water, acid, or humidity. Gold is the most inert metal. It does not react with oxygen. It doesn’t rust. It retains its luster for thousands of years. Silver reacts slightly and it is darkened with sulfur. However, much less than other metals. <\/p>\n
Other metals, such as iron, rust occur when they come in contact with air. Copper is green. Aluminum develops an oxide layer. So when the ancients buried gold and silver ornaments in the tombs. They will still shine thousands of years later. This stability makes them immortal metals. <\/p>\n
Pure presence in nature<\/strong><\/span><\/p>\n }<\/p>\n Ancient people did not have the technology to melt metals. Most metals are in the form of ores (oxides or sulfides). They need a high temperature to extract. <\/p>\n Gold and silver are often found in rivers and rocks in their pure (original) form of small grains or fragments. These can only be shaped by lifting them with a hammer. Thus, the use of gold began around 5000\u20136000 BC. The earliest evidence is from the varna culture of Bulgaria (4600 BC). The use of silver began around 4000 BCE. <\/p>\n Physical Properties: Beauty and Ease of Functioning<\/strong><\/span><\/p>\n }<\/p>\n Rare but not very rare: both are rare enough to be valuable. However, they are not so rare that they are impossible to find. <\/p>\n Glitter and color: The yellow glow of gold and the white sparkle of silver are very attractive to the eye. <\/p>\n Flexibility and flexibility: One gram of gold can be hammered into a thin sheet (golden leaf) of 1 square meter. Silver is the best conductor of electricity and heat. They do not melt easily (the melting point of gold is 1064\u00b0C, that of silver is 962\u00b0C). This makes them safe to make jewelry. <\/p>\n Why did TAG_OPEN_strong_65 they become symbols of currency and value in history? <\/strong><\/span><\/p>\n Durable: <\/span> They are not tainted, making them ideal for storage as wealth. It can be broken into small pieces. <\/p>\n Easy to identify: <\/span> Hard to duplicate. <\/p>\n Worldwide Acceptance: <\/span> Valuable in every culture. <\/p>\n The first gold and silver coins were minted in Lydia (modern Turkey) in 600 BC. Rupi (silver) and hiranya (gold) were used as coins in India from ancient times. <\/p>\n Why is it still used so extensively? <\/strong><\/span><\/p>\n In India, 600-800 tons of gold is used annually for jewelry for beauty and social prestige.TAG_CLOSE_span_54 TAG_OPEN_span_54 <\/p>\n Investment: <\/span> Gold is a safe investment, its value increases in times of inflation and crisis. <\/p>\n Industrial Applications<\/strong><\/span><\/p>\n Silver: Electronics (best conductor), photography, mirrors, batteries. <\/p>\n <\/span> Electronics (connector), dentistry, spacecraft. <\/p>\n Cultural Significance: Traditions in Weddings and Festivals. <\/p>\n Perfect blend of science and human nature<\/strong><\/span><\/p>\n Gold and silver are natural metals. It strikes the perfect balance between rarity, sustainability, beauty and utility. Other metals are either very common (like iron), very reactive or very slow to be detected (like platinum). <\/p>\n People today choose what they chose thousands of years ago \u2013 because science and the human spirit are at their core. Next time you wear gold jewelry. Remember, it’s not just metal, it’s a living example of science and history. \u2013Agency<\/p>\n","protected":false},"excerpt":{"rendered":" Kathmandu.
