AbstractEight ornaments and a dagger were analyzed using completely non-destructive techniques to determine their alloy compositions and to draw conclusions about the production technology. Prompt-gamma activation analysis and time-of-flight neutron diffraction proved that the studied objects are tin-bronzes. Difference was observed in the amounts of ore-related minor components (arsenic, silver, nickel) of the objects belonging to the two distinct archaeological sites. Based on the diffraction analysis of the microstructure, the objects are casts that were exposed to different degrees of manufacturing to reach their final forms.
