Chalcolithicとは 意味・読み方・使い方

The Chalcolithic (Ancient Greek: χαλκός khalkos "copper" + Ancient Greek: λίθος lithos "stone") period or Copper Age, also known as the Eneolithic/Æneolithic (from Latin aeneus "of bronze"), is a phase of the Bronze Age in which the addition of tin to copper to form bronze during smelting remained yet unknown by the metallurgists of the times. The Copper Age was originally defined as a transition between the Stone Age and the Bronze Age. As metal was being used and therefore the Copper Age was part of the Age of Metals, it had to be and has to be in the Bronze Age and not in the Stone Age.
