This paper presents the study of bronze artefacts resulting from an accidental discovery in the Preajba neighbourhood of Târgu Jiu municipality, Gorj County, Romania. In addition to the presentation of the field assessment and artefact analogies, the objects were analysed using optical microscopy (OM) and scanning electron microscopy (SEM) coupled with Energy-Dispersive X-Ray (EDX), in order to highlight the morphology of the corrosion crust and to determine the elemental composition of corrosion and soil contamination products. Thus, it was possible to establish the nature of the materials used and the manufacturing technology.
