High-resolution archaeometallurgical analysis of production debris offers a direct means of reconstructing ancient metalmaking traditions, yet remains underexplored relative to the study of finished artefacts. By integrating slag morphology, microstructure and compositional data from Late Bronze Age Taldysai, this study reconstructs, for the first time in Eurasian Steppe archaeology, a continuous 300-year tradition of copper-alloy production. The results reveal technological continuity alongside innovation, including advanced furnace designs, shared metallurgical knowledge and episodes of experimentation. The authors state that these findings position local semipastoralist communities not as peripheral adopters but as active innovators at the heart of Bronze Age Eurasian metallurgical developments.
