The Glitters of Gold
As they say, not all that glitters is gold. But what is it in
gold that makes it glitters? Is it because of its chemical
components, its unique characteristics, or simply because it is
just the way it is?
Scientifically, gold is a metal and at the same time a chemical
element with the symbol Au, which stands for aurum, in the
periodic table. Of all the different kinds of metals, gold is
deemed as the most malleable and is ductile or one that can be
flexed.
That is why it is the most popular metal being used for
jewelries, trinkets, and charms.
In many instances, the gold's color is yellow, but it can also
have other colors such as ruby, black, or even purple depending
on the "plasmon frequency" placed in the observable scope.
In this instance, plasmon frequency is the one responsible in
reflecting the yellow and red light and the blue light to be
sucked up.
For so many years now, gold has been a part of our human
history. In fact, it was even used by the early human populace
as an apparatus in their primitive way of living. It has
captivated man's desire for existence and superiority with its
unique traits and functions.
In 4000 BC, the Europeans were said to be the first people who
used gold in their daily living. They crafted it into different
kinds of jewelry and extremely classy pieces of artistic objects.
In Egypt, gold was reportedly used as an element in King
Tutankamen's mask. Several historical reports asserted that the
golden mask of the king had preserved its radiance and luster
even after so many years of civilization that had passed.
Even in the past events, gold has long been a symbol of royalty
and superiority. According to the Old Testament, gold was a
symbol of King Solomon's riches. It was also a symbol of
thanksgiving and appreciation just like what the Queen of Sheba
had done when she
gave King Solomon large amount of gold as a
sign of gratitude.
However, it was only during the fifth century when the Chinese,
Greek, and Arabic civilization had introduced its new concept,
which eventually resulted to the introduction of the science of
chemistry. Here, gold is now considered as a chemical element,
one that has more stable and practical function and not just any
symbolic matter.
It was after the introduction of chemistry that it gained more
popularity. From then on, gold has been considered by the people
as one of the most prized metals. They have used it in making
different icons, statues, and jewelries.
In today's contemporary society, the most malleable metal of all
has surpassed its usual traditional functions. Nowadays, it is
being used in the new technology where man is no longer simply
fascinated by its luster and shine but also by its capability of
producing quality products like computers, home appliances, and
mobile phones.
This wonderful metal is also used in embroidery, dentistry,
ceramics, and even photography. In fact, cancer patients have
found more of its feasible uses. There are many instances
wherein it is being used when treating cancer patients and other
diseases.
These are just a few of the many uses of gold. It serves as a
viable element not just for jewelries and art objects but to all
aspects that give humanity the reason to live life to its
fullest.
So, now we know that this remarkable metal is not just
considered pure and rare because of its characteristics but to
the many functions and uses, as well, that it has served mankind
throughout the years.
