Samples of nine vessels from the site on the southern beach of Ashdod were examined petrographically using a polarized microscope to identify the origins of the vessels. According to the petrographic results, it appears that none of the vessels sampled were locally made. The variety of the vessels’ raw materials bears witness to the commercial relations this site had with other sites located along the northern coast of Israel and the Lebanese coast, as well as its ties overseas. The internationality of the Late Bronze Age is well-expressed in the petrographic results.
