A Note upon Native Copper: its Occurrence and Properties

Extract

Since the publication in 1951 of an article upon native copper considerable progress has been made concerning the occurrence and use of the metal in prehistoric Europe. In 1955 an important paper appeared by Professor Nestor dealing with the prehistory of the metal in Roumania and in 1957 Professor Pittioni published an outstanding survey and technical discussion upon the subject.

As archaeological research continues we may expect to learn more about the extent to which native copper was used by early man. It is generally agreed that some utilization of the native metal goes back even to Neolithic times, and that the first phase was that of cold hammered native copper, very shortly to be followed by its more extensive working in an annealed condition. The question of what quantity of native copper would have been available to prehistoric man, and was in fact used by him in different countries has hardly been touched upon as yet. No doubt in certain regions the quantity of native metal was very appreciable. For instance, Professor Nestor considers that in Roumania, and certain neighbouring countries, important deposits of copper minerals and notable quantities of native copper existed, and still exist. From Professor Nestor's discussion it appears that there was quite an intensive utilization of the local deposits of native copper in Roumania, not only as a ‘forged’ native copper phase, but leading on to the melting and casting of the metal culminating with the remarkable shaft-hole axe hammers and axe adzes so well known to archaeologists.
