At first to shape an object the cold metal was hammered.  Later on the metal was heated and then hammered into shape.  Natural copper ore was soon used up; from then on copper compounds were imported.  These were melted by heating with charcoal in order to remove the impurities.  By 2500 B.C. copperwork in Mesopotamia had advanced to the pouring of the melted copper into many piece molds.  \r\nThis copper spearhead once fitted into a wood handle.  Typical copper objects produced in Mesopotamia were pins, awls, projectile points, celts, axes, saws, daggers with riveted handles, socketed spears, and arrowhead.","inline_note":"","footnote":""}]}]
