ARHEOMETRUA KERAMIKE BRONČANOG DOBA S TROGIRSKOG PODRUČJA. (Croatian)

ARCHAEOMETRY OF BRONZE-AGE CERAMICS FROM THE AREA OF TROGIR. (English)

The paper presents the results of archaeometric analysis of pottery from several Bronze Age sites in the area of central Dalmatia. A mineralogico-petrographic analysis of 38 thin sections of pottery was carried out using the method of optical microscopy, while the mineral composition of a smaller number of samples was determined using the X-ray powder diffraction method. The research provided data on the characteristics of the clay raw material, the type and proportion of non-plastic tempers intentionally added to the clay, and information on the production techniques and firing temperatures. The research showed that Bronze Age potters very likely used local, easily available clay and non-plastic tempering material: calcite, sedimentary rocks and grog. Through consideration of technological choices, changes in pottery practices between the first and last phases of the Bronze Age were observed. The long-term tradition of using calcite, which becomes a dominant tempering material in the last phase of the Bronze Age, is evident. On the other hand, from the Early Bronze Age, potters used grog, either alone or in combination with calcite and, more rarely, crushed sedimentary rocks, and this practice seems to have been slowly abandoned after the Late Bronze Age. The results therefore indicate a correlation between selection of tempering material and chronological patterns, that is, such a practice could have been related to the periodic influences of various social factors.

U radu se donose rezultati arheometrijske analize lončarije s nekoliko brončanodobnih nalazišta na području srednje Dalmacije. Provedena je mineraloško-petrografska analiza 38 tankih izbru-saka keramike metodom optičke mikroskopije, dok je na manjem broju uzoraka mineralni sastav određen metodom rendgenske difrakcije na prahu. Analizom rezultata dobivene su informacije o karakteristikama glinovite sirovine, podaci o vrsti i udjelu ne-plastičnih primjesa, namjerno dodavanih glini, ali i informacije o tehnikama izrade i temperaturama pečenja keramike. Istraživanje je pokazalo da su brončanodobni lončari vjerojatno koristili lokalnu, lako dostupnu glinu i da su joj dodavali neplastične primjese: kalcit, sedimentne stijene i grog. Razmatranjem tehnoloških izbora uočene su promjene u lončarskim praksama između prve i posljednje faze brončanog doba. Također, razvidna je dugotrajna tradicija upotrebe kalcita koji u posljednjoj fazi bronča- nog doba postaje dominantna primjesa. S druge strane, od ranoga brončanog doba lončari smjesi dodaju i grog, samostalno ili u kombinaciji s kalcitom te rjeđe usitnjenim sedimentnim stijenama, a takva se praksa postupno napušta od kasnoga brončanog doba. Stoga, rezultati ukazuju na vezu između odabira primjesa i kronoloških obrazaca, odnosno takva praksa mogla je biti povezana s periodičnim utjecajima različitih društvenih faktora.
