“…and south-eastern Europe and the Near East, and pieces of raw material and various products were distributed widely over long distances, up to hundreds of kilometers from the sources. Obsidian management, and in its context, regional and interregional contacts and a variety of interactions in the Neolithic and Bronze Age in various parts of Europe, have long been the subject of interest of a large group of researchers (e.g., Kaczanowska and Lech 1977;Kulczycka-Leciejewiczowa 1979;Torrence 1986;Bacskay et al 1987;Kaczanowska, Kozłowski 1997;Carter 1998;Szeliga 2007;Kozłowski et al 2014;Milić 2016;Trykot 2017;Moutsiou 2019;Szeliga and Zakościelna 2019;Szeliga et al 2021). Moreover, in recent decades, such studies, in particular concerning the characteristic features of raw material from individual sources and extraction sites, have found strong support from effective analytical tools in the form of modern physicochemical methods (Williams, Nandris 1977;Williams-Thorpe et al 1984;Hughes and Werra 2014;Milić 2014;Bonsall et al 2017;Orange et al 2017;Riebe 2019;Dillian 2020;Kaminská 2021;Werra et al 2021, further literature there).…”
