TY - JOUR N2 - Investment casting technology that utilizes lost-wax casting is one of the most-important achievements of ancient society. In Lower Silesia, Poland (Grzybiany, Legnica county), a 7-6 BC casting workshop was discovered with numerous artifacts, confirming the existence of the manufacturing process of metal ornaments using ceramic molds. The paper presents the research of molds and casts from the Bronze and Early Iron Ages. Microscopic analyses of the casting molds were performed, along with radiographic and chemical composition tests of the artifacts (the latter employing the use of the X-ray fluorescence spectroscopy method). The clustering method was used for alloy classification. The microstructure was analyzed by means of Scanning Electron Microscopy with Energy Dispersive Spectroscopy. Conclusions from the research were utilized in further experiments L1 - http://journals.pan.pl/Content/106666/PDF/AMM-2018-2-12-Garbacz.pdf L2 - http://journals.pan.pl/Content/106666 PY - 2018 IS - No 2 EP - 624 DO - 10.24425/122385 KW - archeometallurgy KW - copper alloys KW - investment casting technology KW - lost-wax casting KW - x-ray spectroscopy A1 - Garbacz-Klempka, A.
