Several glass mosaic tesserae were recovered during the archeological excavation of the thermal baths at the ‘Villa dei Quintili’ in Rome and dated to the second century ad. This work reports the results of an archeometrical investigation performed, through a multi-technique approach, on 19 colored opaque tesserae. The aims of the study were (1) the characterization of coloring and opacifying agents used for the production of the glass tesserae and (2) the definition of the technological… Expand

Chemical Characterization of Vitreous Finds from Cosenza Cathedral (Calabria – Italy) by the Combined Use of Analytical Techniques
Abstract This article presents an archaeometrical research carried out on twenty-six vitreous finds collected in the Cosenza Cathedral (Calabria, Italy). The glasses have been subdivided in twoExpand
Handheld XRF and Raman equipment for the in situ investigation of Roman finds in the Villa dei Quintili (Rome, Italy)
In the present work, a variety of fragments of frescoes coming from the Villa dei Quintili in Rome (Italy) and dating back to the II century A.D. were subjected to, first of all, an X-rayExpand
In situ non-invasive multianalytical methodology to characterize mosaic tesserae from the House of Gilded Cupids, Pompeii
Mosaics, one of the most important decorative artworks in the Roman culture, were usually elaborated with a set of tesserae joined with lime or others binders to form geometric or figurativeExpand
Vitreous tesserae from the calidarium mosaics of the Villa dei Quintili, Rome. Chemical composition and production technology
Abstract The archaeological excavation of the Villa dei Quintili in Rome (2nd century AD) brought to light one of the most impressive residential complexes of the Roman Empire. Among the astonishingExpand

The Technology of Copper-Based Red Glass Sectilia from the 2nd Century AD Lucius Verus Villa in Rome
This work aimed to investigate the origin of different red hues of Roman copper-based red opaque glass sectilia, to shed light on the production technology behind them. This objective was achieved byExpand
From Crystals to Color: A Compendium of Multi-Analytical Data on Mineralogical Phases in Opaque Colored Glass Mosaic Tesserae
Micro-structural and compositional features of glass tesserae, where different types of crystalline phases were detected are presented in well-structured synoptic tables, following a summary on historical–archaeological information on their use. Expand


Glass mosaic tesserae from Pompeii: an archeometrical investigation
This work reports the results of an archaeometrical investigation performed, through a multi-technique approach, on a series of Roman glass mosaic tesserae found in Pompeii excavations. Chemical andExpand
Colourants and opacifiers in seventh and eighth century glass investigated by spectroscopic techniques
It is apparent that medieval glassmakers in Italy could obtain a wide range of colours by exploiting the presence of iron and manganese as contaminants of sand and flux and controlling the amount of oxygen let into the furnace. Expand
A non-invasive study of Roman Age mosaic glass tesserae by means of Raman spectroscopy
Abstract Ancient mosaic tesserae are a range of materials of very varied and complex nature, including pottery, stone and glass. Raman spectroscopy is a powerful tool for the analysis of all theseExpand
Roman coloured and opaque glass: a chemical and spectroscopic study

Rediscovering ancient glass technologies through the examination of opacifier crystals
The aim of the study is to understand how antimonate opacifying crystals were obtained throughout history. Two archaeological glass productions opacified with calcium and lead antimonates are studiedExpand
Archaeometric investigation of Roman tesserae from Herculaneum (Italy) by the combined use of complementary micro-destructive analytical techniques
Abstract Vitreous tesserae from two mosaics in Herculaneum (Italy) dating from the 1st century AD have been investigated in order to gather information on Imperial Age opaque glass. The combined useExpand
New insight on the in situ crystallization of calcium antimonate opacified glass during the Roman period
Glass is usually opacified by small crystalline particles, called opacifiers, dispersed in the translucent vitreous matrix. To understand the glassmaking conditions used to produce calcium antimonateExpand
Characterisation of inorganic pigments in ancient glass beads by means of Raman microspectroscopy, microprobe analysis and X‐ray diffractometry
Ancient coloured glass beads from Sri Lanka and Oman were analysed by Raman microspectroscopy for non-destructive identification of inorganic pigments in the glass. Calcium phosphate (Ca3(PO4)2),Expand
