Gold is a precious metal that’s inspiring tales and mysteries for thousands of years. There are many well-known facts on this metal, but a lot of people still do not know all the secrets of gold.
Gold came from space. Practically all gold on Earth was “delivered” by meteors. This fact is confirmed by a scientific study published in the Nature magazine. In the process of forming of our planet, iron “dipped” in the center of it, creating its core. It would be expected that precious metals were also “drawn” in the Earth’s “melting middle”. However, our planet’s mantle has about thousand times more gold than it would have had in that scenario. The cause of this are the meteor showers. About 3.9 billion years ago they brought gold on Earth. For the long time, the origin of this precious metal was one of the secrets of gold!
The secrets of gold
Sunshine. Latin name for gold is Aurum. This name is used in the periodic table of elements. Because of this, the chemical symbol for gold is Au. The source of the word gold used in English and similar languages is German word gulþa. Old English word gelou means – yellow. Croatian name for gold, zlato, comes from Old Slavic word zolto.
Noble properties. Gold melts at temperature of 1064.42 degree Celsius. That is why the temperature of furnaces used to melt gold is higher than 1.100 degrees. Mostly, it’s around 1.200 degrees Celsius. Gold has many properties considered noble. It conducts heat and electricity. It is easily malleable. Also, gold never rusts.
Gold as an investment
A secure investment. Gold is considered as one of the most secure investments possible. Its value rises in the time of economic disturbances. Throughout history, gold has been confirmed as a reliable “keeper” of the value. First coin made completely out of gold was coined by the king Cresus. It happened in the 1st millennium BC. Since then, gold had been the basis of economy. After “gold standard” has been dropped, the use of gold as a guardian against inflation had become more prominent. In the last 100 years, dollar has lost more than 99 percent of its value due to inflation. However, the worth of gold stayed the same.
Golden ducats. In Europe, especially the Mediterranean, the most popular gold coin is ducat. The first country to implement this type of coin was Venice, in the 13th century. The word ducat means a duke. It was the title of the ruler of Mletci, all of the Venetian territories. However, today the word ducat is synonymous with a specific gold coin. It’s the coin with the image of Franz Joseph, coined by the Austrian state mint.
