Copper
and
History |
 |
In
various parts of the world the history of copper is
the history of civilization down to the present day.
It has been one of the main metals used by humankind
throughout the last 6.000 years. Even though it is
very delicate in its unadulterated state in nature,
humans have been able to process it since the very
first beginnings of civilization, and used it to make
tools, weapons and ornaments.
In
prehistory the first humans learned how extract copper
form seams of copper oxide, which had a very striking
colour. Later they succeeded in

extracting
copper from sulphide seams through repeated roasting
and smelting. In later periods they utilized its ability
to be made into an alloy with tin and developed Copper-Tin
alloys; and this period in human history is known
as the Bronze Age.
We
can see from the copper works of the art unearthed
by archaeological excavations that since 4.000 B.C.
copper was widely used in Anatolia, Iran, Iraq and
Egypt, which were the cradles of splendid civilizations.
Our ancestors gave considerable importance to copper
and endowed it with special meanings. For example,
the ancient Egyptians used the sign for immortality
to represent copper. Two thousand years age copper
was associated with the planet Venus and thus with
Cyprus, the birthplace of the goddess Venus.
The
fact that copper had a very striking colour, that
it could be processed and easily made into alloys
and had a high resistance to corrosion, meant that
was extensively used. In later periods copper's other
properties, such as high heat and electricity conductivity
and ease with which it could be soldered, greatly
increased its importance. In addition to its unique
characteristics and the fact that different properties
could be utilized at the same time, copper has become
a principal industrial metal because it is very difficult
to substitute other metals in its place.
In the modern age, as high technology is utilized
in everyday life, copper continues to add brightness
and confidence to people's lives; and copper will
continue to always be one the foundation stones of
modern civilization.
