Abstract
A large number of Mediterranean Group vessels were recovered at the Etruscan site of Spina in northern Italy and dated from the 6th to the 3rd century BC. In this work a number of vessels belonging to the so-called “Group II” were analysed. The samples are mainly Alabastra, Oinochoai, Amphoriskoi, and Hydriai, in general opaque and deeply coloured. The aims of this study are: 1) to characterize these samples since there is a lack of data in literature regarding Mediterranean Group II; and 2) to compare the data obtained with that of glass for previous centuries (Mediterranean Group I) recovered at the same site in order to establish whether they could have the same origin. The chemical analyses of major and minor elements were carried out by electron microprobe and the nature of the opacifying and colouring agents was determined by X-ray diffraction. The sample set is relatively homogeneous and most of the samples can be classified as Low Magnesium Glass produced with natron and a calcareous silicatic sand. The XRD analyses proved the use of lead antimonates in the manufacture of yellow decorations and of calcium antimonates in the white and light blue decorations. The consistency of the chemical compositions of Mediterranean Groups I and II samples makes it possible to hypothesize a common origin.
