Copper was the first metal to fashioned into tools during this time period. Humans had not yet developed the technology to create bronze (an alloy of copper and tin) or to smelt and forge iron.

Originally defined as a transitional period between the Neolithic Age and the Bronze Age, the Copper Age (or Chalcolithic Age, or Eneolithic Age) is now regarded to be part of the Bronze Age because it is characterized by the use of metals. It was during this time period that early metallurgists found that the addition of tin to copper produced the harder metal, bronze.

The Neolithic followed the Paleolithic Period, or age of chipped-stone tools, and preceded the Bronze Age, or early period of metal tools. A brief treatment of the Neolithic Period follows. For full treatment, see Stone Age: Neolithic and technology: The Neolithic Revolution.
