Researchers of the ancient metal industry of the Caucasus for a long time noted the relatively late appearance of bronzes with a tin alloy in the North-Western Caucasus, not earlier than the end of the 2nd millennium BC., considered them supposedly imports. This article discusses a series of recently discovered burials in the foothills of Adygea at the beginning of the late Bronze Age of the Shushuk-II period (XVIII-XVI centuries BC), in which a large series of tin bronze jewelry was found. The authors conclude that tin bronze appears in the North-Western Caucasus already in the first centuries of the 2nd millennium BC. and was used exclusively for the manufacture of jewelry, while objects of the "working metal" were made of arsenic bronzes.
