摘要：This short communication summarizes the preliminary results of mineralogical (XRD, ND) and chemical
(PGAA) investigations of one of the earliest metal finds of Hungary. Archaeological excavation of Polgár-
Csőszhalom site of the Neolithic Csőszhalom Culture (B.C. 5000-4400) provided a unique copper bead necklace.
Its present condition requires efficient intervention for conservation purposes. Our scientific analysis provided
basic information about the state of the finds to establish the appropriate strategy for their restoration and
storage. According to our results, the beads are highly altered (there is no metallic copper present in their
cores). The predominant corrosion product is paratacamite, but also atacamite, cuprite and reactive agents are
present in the finds.
