It is not always understood why is Gold also simply beautiful to look
at. It is extremely malleable and pliable. A one-ounce piece of gold can
be beaten down to 5 micrometers thick – that is 1/10 the diameter of a
human hair – and laid out into 50 miles of wire.
It can also be made so
thin that it becomes a translucent sheet; in fact, astronaut’s visors
are covered in a thin gold film to protect their eyes from glare. Gold
also has anti-inflammatory and other medicinal properties.
Ancient
Sumerians of Mesopotamia (modern-day Iran and Iraq) were the first, at
around 5000 BC (some sources indicate 4000 BC), to use gold for
ornaments. The Egyptians would soon fall in love with the precious metal
too. But gold was mostly used for personal adornment; the first gold
coins for trade were issued by Egyptian pharaohs only at around 2700 BC.
Large scale gold coinage for the monetary purpose was introduced in by
King Croesus during his reign (560 – 546 BC) of Lydia. Croesus became
one of the wealthiest persons ever. By firing neutrons into a nucleus to
change an atom, gold can be produced from cheap metals. However, the
nuclear process costs far more than mining gold.
