Three axes and a mace head fragment from the assemblage were subjected to chemical composition and metallic texture analyses by SEM-EDS. While the axes were found to be composed of pure copper, in agreement with the common observation of " working tools " from this period in the southern Levant, the mace head was found to have a unique composition. In contrast to the common copper arsenic/antimony alloy used for "prestige" objects at this period, the mace head was made of leaded copper with lead concentrations N70 wt.% (in inclusions). This is the first such object reported from the Chalcolithic Levant. We suggest that similar to the use of arsenic/antimony, the addition of lead was primarily a technological requirement, done in order to facilitate production with the lost wax technique. Furthermore, this leaded copper mace head probably reflects an attempt to continue with production of "prestige" objects at times of shortage in the supply of As/Sb bronzes, and testifies for the important role these artifacts had in Ghassulian societies.
