Technology of metallurgy and metal treatment on territory of undercurrent Angara in Middle Ages: experience of experimental and traceological investigations

The article presents the results of experimental and traceological investigations of metallurgy and metal treatment technologies on base of studying archaeological materials from medieval settlements of Undercurrent Angara. The author makes characteristic of main production steps in metallurgy and metal treatment, and reconstructs ways of stone tools using in specific operations which consist these steps. General criterion for the reconstruction was specific kinds of use-wear traces fixed on stone artifacts.
