Throughout much of recorded
history, bronze is one of the most significant metals for virtually
every thriving civilization, and is also considered one of the most
innovative alloys created by man. Different scores of tools, weapons,
armor, and priceless pieces of art have been forged using bronze,
most of which have stood the test of time.
Bronze is known as the
oldest
alloy humans ever made, with its very first variation created
using a mix of copper and arsenic during 3500 B.C. Realizing that tin
would make the resulting material stronger and lighter, arsenic was
dumped and replaced with tin. The period when bronze smelting was
widespread came to be known as the Bronze Age, which is characterized
by a huge collection of cups, urns, vases, and even simple home
containers forged in bronze. One of the first people to use bronze on
a wide scale were the ancient Sumerians, a group of people who
thrived along the Tigris-Euphrates Valley.
By 3000 B.C., bronze-making
gradually spread to neighboring kingdoms like Persia. The ancient
Egyptians and Chinese began using bronze around 2000 B.C., where some
of the earliest bronze castings were created by pouring the molten
metal mixture into molds made of sand. However, bronze was slowly
usurped by wrought iron as the main material for weapons because
wrought iron is much easier to find, giving way to the Iron Age.
Today, bronze is still being used in making smaller household items,
as well as several industrial applications.
