The metal composition of a group of eneolithic copper artefacts from  the  Ljubljansko  barje  (Ljubljana  Moor)  was  determined  by  ICP-AES  analysis.  Half  of  the  finds  come  from  nineteenth  century  excavations  of  prehistoric  pile  dwellings  at  Ig  and  the  remaining objects were found on the bed of the River Ljubljanica in  the  twentieth  century.  The  material  has  been  approximately  dated  to  the  fourth  and  third  millennia  BC.  Analysis  showed  that  all  the  objects  are  made  of  copper  with  various  impurity  patterns differing in terms of the concentration ratios of arsenic, antimony,  nickel,  silver  and  lead.  The  majority  of  the  artefacts  are of a copper type with dominant antimony, copper with domi-nant arsenic was found only in two artefacts. All artefacts also contain  lead  and  silver  as  trace  elements.  The  results  showed  that the classification of the metal composition into the copper types  that  have  been  identified  in  the  recent  German  research  by means of multivariate analysis was reasonable.
