“…Obsidian was subject to conveyance and long-distance distribution since Palaeolithic times (see Moutsiou 2014; and, during the Neolithic, these activities intensified. Volcanic glass artifacts are present in inventories connected with Linear Pottery culture sites (especially in the Želiezovce group), in western Slovakia, in southern Poland, and in ALPC assemblages in eastern Slovakia and Hungary (Kulczycka and Kozłowski 1960;Godłowska 1982;Milisauskas 1986;Šiška 1998;Grygiel 2004;Kaczanowska and Godłowska 2009;Szeliga 2009;Tunia 2016;Biró 2018;Kaminská 2018;Riebe 2019;Szeliga et al 2019a;2019b). Even higher demand for obsidian seems to have existed during the Late Neolithic (following the decline of the Bükk culture, during the beginning of the Lengyel culture), when raw material exchange and conveyance moved semi-products and finished products of obsidian as far as the central Danube region (Šiška 1989, 77), Czechia (Burgert 2015;Burgert et al 2016;2017), Poland, and the Polish Lowlands (Więckowska 1971;Kabaciński 2010;Wilczyński 2016).…”
