The casting workshop in Grzybiany, in Lower Silesia (SW Poland) is a valuable source of knowledge on the development of casting techniques in the 7 – 6 centuries BC. Abundant evidence found on the archaeological site points to cast manufacturing by means of precision casting in ceramic moulds (lost-wax molding). The workshop is the biggest collection of moulds for bracelet, necklace and other smaller decorative artefacts in Poland. The aim of the work is to conduct the research of the moulds and casts with the view of performing a computer reconstruction of the casting moulds from the Bronze and Early Iron Age, based on the Grzybiany finds. As part of the work, both the microscopic structure and defectoscopic analyses of the casting moulds were performed. Chemical composition of the casts was tested using the X-ray fluorescence spectroscopy method. Based on these results and using computer modelling methods, a geometric visualisation was performed, which is the bases for preparing the visualisation of the process of pouring liquid metal into the moulds, reconstructing both the technology and the alloys used.
