Abstract

Na groblju u Nuštru, 2011. godine, u grobnicama su pronađene staklene perle koje su bile dio nakita vrata, odnosno ogrlica. Groblje datira u razdoblje ranog srednjeg vijeka, VII. i IX. stoljeće, a perle pripadaju avarskoj vrsti nakita. Zbog značajne uloge nakita kroz povijest, posebice perli, provedena je njihova analiza dvjema metodama: 9 uzoraka analizirano je ICP-AES kojoj je prethodilo taljenje uzoraka potpomognuto mikrovalovima, a ostalih 11 uzoraka nedestruktivnom PIXE metodom. Obje metode pokazale su se veoma preciznima i pogodnima za određivanje elemenata u tragovima. Dobiveni rezultati međusobno su uspoređivani, a može se uočiti kako su najzastupljeniji elementi u svih 20 uzoraka natrij, magnezij, aluminij, kalij, kalcij, mangan, željezo, bakar i olovo. Međutim, koncentracije dobivene destruktivnom metodom analize veće su od onih dobivenih nedestruktivnom metodom analize. Obzirom na velik broj elemenata koji čine sastav perli zaključeno je kako su perle rađene od staklene paste, odnosno od različitih smrvljenih vrsta stakla, oblikovanih i povezanih gumi arabikom i vodom.

Abstract (english)

At the cemetery in Nuštar, on the year 2011, in the tombs were found glass beads that were part of the neck jewelry or collar. The cemetery dates back to the period of the early Middle Ages, the 8th and 9th centuries, and beads belong at the avarian type of jewelry. Because of the significant role of the jewelry throughout the history, especially beads, their analysis was conducted by two methods: 9 samples were analyzed by ICP-AES after destructive sample preparation, and the other 11 samples by non-destructive PIXE method. Both methods have proven to be very accurate and suitable for determination of the trace elements. The obtained results are compared with each other, and it can be seen that the most common elements in all of the 20 samples are sodium, magnesium, aluminum, potassium, calcium, manganese, iron, copper and lead, although the concentrations obtained by the destructive method of analysis are higher than those obtained with non-destructive method of analysis. Regarding to the large number of elements that make up the composition of beads it can be concluded that the beads are made of glass paste, different types of crushed glass, shaped and linked by the mixture of gum arabic and water.
