Bronze

Mixing the metals copper and tin creates

bronze. Bronze, like other mixtures of

metals, is called an alloy. Bronze is

harder and stronger than copper. It also

does not wear away as easily as either

copper or tin. For these reasons bronze is

often used to make tools and machinery.

Bronze is also used to make electrical

hardware, springs, fasteners, and coins.

Bronze has been the most popular metal

for making statues and other artistic

objects since ancient times.

Working with Bronze

After melted bronze is poured into a

mold and begins to cool, it expands. As

the bronze expands, it fills in every detail

of the mold. When the bronze cools

further and hardens, it shrinks a little

bit. This makes the final object easy to

remove from the mold. Bronze also

changes colors when exposed to air and

water. This effect is called a patina and

can be very beautiful.

History

People first discovered how to make

bronze more than 5,000 years ago. The

discovery of bronze allowed ancient

peoples to make tools and weapons that

were stronger and longer lasting than

any made before. These advances were

so important that the ancient period of

bronze making came to be called the

Bronze Age. People later began making

statues, church bells, doors, bowls, and

many other objects out of bronze.

Bronze Age

The Bronze Age was a time in early

human history when people first began

to use tools made of bronze. It began in

some places about 5,000 years ago. It

began later in other places. Learning

how to use bronze led to advances in

many areas of human life.

Background

The earliest humans lived during the

Stone Age. Stone Age humans made

tools and weapons of stone. By about

6500 BC people had learned how to

shape copper into tools and other

objects.

Eventually people learned how to mix

tin with copper to make bronze. They

probably discovered how to do this by

accident. In some places copper and tin

are mixed together naturally in the

ground. When ancient metalworkers

melted this mixture, they made a form

of bronze.

Bronze looked like copper. But it was

harder and more useful for making

tools, weapons, and artwork.

Events of the Bronze Age

The Bronze Age began in Greece and

China before 3000 BC. Bronze Age cultures

also developed in Mesopotamia (in

modern Iraq), Egypt, and the Indus

River valley (in modern Pakistan). The

Bronze Age had spread to Great Britain

by about 1900 BC. Peoples outside

Europe, North Africa, Asia, and the

Middle East did not have a Bronze Age.

At first only rich people could afford

bronze. For a long time farmers and

craftspeople used cheaper stone tools to

do their work. But eventually more

people did metalworking as a full-time

job. Metalworkers, other craftspeople,

and farmers came together in cities to

trade their goods. This helped civilizations

to grow. Two new inventions—the

wheel and the ox-drawn plow—also

helped Bronze Age civilizations to grow.

In about 1200 BC people learned how to

shape iron into tools. This began the

Iron Age and ended the Bronze Age.

Brown, John

As an abolitionist, John Brown wanted

to end slavery in the United States.

Unlike most abolitionists, however, he
