The presence of numerous orange, violet, red or red brown lumps of raw pigments is a very common characteristic of the deposits and destruction layers of the extensive Middle Bronze Age settlement that has come to light during the most recent excavations of the 22nd Ephorate of Prehistoric and Classical Antiquities, to the south and southwest of the known Late Bronze Age settlement at Ialysos on Rhodes. This paper presents the results of physicochemical analysis (observation and microanalysis with SEM-EDX, XRD and FTIR spectroscopy) of selected samples, revealing the composition of the raw pigments material and their manufacturing technology. Significant information is gained on an important aspect of the technology and its evolution during this period, which until recently was regarded as one of the darkest periods of the prehistoric Aegean.
