Numerous bronze monuments and objects with multiple applications have been obtained from this archaeological site. One ofthe discovered artifacts is a bronze dagger belonging to the early second millennium BC. In the present study, the intended dagger is analyzed using metallographic microscopes (OM), scanning electron microscope (SEM-EDS), X-ray diffraction (XRD), and radiography. The results and data obtained from device analysis of the dagger indicated Copper-Arsenic alloy (Cu- As) which hasbeen made using casting method. The existence of Cuprite, Tenorite and Paratacamite phases indicated the variable environmental conditions which had resulted in the brittleness and flimsiness of the bronze dagger.
