Sažetak
Analysis of incrustation of Lasinja culture pottery from three sites in Croatia White incrustation is one of the decorating techniques used on middle Eneolithic Lasinja culture pottery. The aim of this presentation is to show the composition and technology of the white incrustation paste. From three sites in Central Croatia, 7 samples of incrusted pottery were analyzed. The sites are located in the Central part of Croatia. Old town Barilović and Crkvišće-Bukovlje are only few kilometers away from each other, south to the town of Karlovac. The site of Brekinjova kosa is placed close to the town of Glina, about 50 km to the southeast of the above mentioned sites. Five of the analyzed pottery samples belong to the Eneolithic Lasinja culture, absolutely dated from 4300 to 3900 cal BC: three of them are from the site of Crkvišće-Bukovlje, one from the Old town Barilović and one from the site Brekinjova kosa. For comparison two samples from Brekinjova kosa were analyzed. One of them dates to the late Eneolithic Vučedol culture (cca 3000 – 2400 cal BC) and the other one to the Early Bronze Age Vinkovci culture (cca 2500 – 2000 cal BC). The composition and technology of the white incrustation paste on prehistoric pottery was analysed and described. Deep field optical microscopy was used for structural investigations. Chemical composition of incrustation paste was determined by chemical tests. Scanning Electron Microscopy (SEM) coupled with an Energy Dispersive Spectrometer (EDS) was used for additional particle analysis. The paste was applied in incisions or flutes, up to 1, 5 mm deep and up to 2 mm wide. Pottery ornaments were incised using a sharp tool in the still fresh material and before firing. Incrustation paste was applied in incisions or flutes, previously impregnated with organic resin. The incrustation material is of excellent whiteness and powdery texture. The material was mixed with organic binder and applied in the incisions/flutes. At the end of process the whole surface was resin coated which resulted in a shiny thin layer. The chemical tests and EDS analysis showed calcium-phosphate composition. The elements stoichiometric ratio closely matches the composition of hydroxyapatite. The incrustation particle shape and structure is in accordance with mammal bone material structure. It is possible that the material was obtained by deer antler burning. In resin remains plant material particles could be found ; the tissue structure is similar to birch-tree. Although from different time periods, all of the samples show similar composition of incrustation paste. It is interesting to mention that the results of incrustation analysis from eastern Croatia belonging to late Eneolithic Kostolac and Vučedol cultures as well as to the middle Bronze Age Transdanubian Encrusted Pottery culture showed almost the same composition of the white paste.
