Stone Age

Stone Age

Stone Age occurred before the metal is known and the means of culture mainly made of wood and stone in addition to the bone. This stone age can be divided again over:

Old stone age (Paleolitikum)
Old stone age (palaeolitikum), is so called because the stone tools made by humans still roughly trimmed, not sharpened or dipolis. When viewed from the point of income from the trade of this period is called the hunting and gathering food simple level. Supporting this culture is composed of Homo Erectus.
Middle stone age (Mesolitikum)
In the middle stone age (mesolitikum), stone tools of this age has smoothed most especially the part that is used. Pottery is also already known. This period is also called the hunting and gathering food advanced. Supporting this culture is the homo sapiens (man now), namely race Austromelanosoid (majority) and Mongoloid (minority).
New stone age (Neolithic)
Stone tools of man-made new stone age (Neolithic) has been ground or dipolis so smooth and beautiful. In addition to pottery weaving and batik are also already known. This period is called the plant. Supporting this culture is the homo sapiens with Mongoloide race (majority) and Austromelanosoide race (minority).

Metal Age

At the time of Metal people are able to make the tools of the metal on the side of the stone tools. People already familiar with metal melting technique, print them into the tools he wants. Metal tool-making techniques are of two kinds, namely the stone mold called bivalve and with clay and wax mold, called acire Perdue. This period is also called the perundagian because in society arise undagi group of skilled hand work. Metal Age is divided into:
Copper Age
People using copper as a means of culture. Cultural tool is only known in some parts of the world alone. In Southeast Asia (including Indonesia) are not known term copper era.
Bronze Age
At this age people are able to mix copper with tin with the ratio 3: 10 in order to obtain a harder metal.
Iron Age
At this age people are able to melt the iron from the seeds to be poured into the tools necessary. Iron smelting technique is more difficult than copper or bronze smelting technique for melting iron requires a very high heat, namely ± 3500 ° C.

Age of metals in Indonesia is dominated by the tools of the bronze age metal that is also called the Bronze Age. Iron tools found in the days of small amounts of metal and shaped like a bronze tools, because most iron tools, found in the time history.

Between the time of Neolithic and metal era megalithic culture has evolved, namely the use of culture media large stones as tools, even the top of megalithic culture precisely at the time of the metal
