Why did the use of antimony-bearing alloys in Bronze Age …
On the other hand, Anatolian evidence has gaps regarding the Early Bronze Age metal production centers; thus, no confirmation is possible at this stage about the intentionality of the production process. Similar to arsenical copper alloys, use of antimony has a problematic nature regarding the identification of intentionality.
