“…The bands at 139 and 456 cm -1 show the presence of Pb 2 Sb 2 O 7 [32]. Further, the bands at 237 and 670 cm -1 can be identified as Ca 2 Sb 2 O 7 [32]. The band at 969 cm -1 will be discussed in Sect.…”

“…The band at 516 cm -1 is not identified, but as it is a rather broad band, it is probably a dissolved feldspar. The broad band at 1087 cm -1 can be attributed to m max Si-O vibrations of soda-lime glasses [32]. The sharp band at 659 cm -1 is not identified.…”

“…These Raman results agree somewhat with the micro-EDXRF; the micro-EDXRF intensities for lead were higher at the sample surface compared to the interior, but this was only found for the first few spots and did not continue gradually as was the observed trend in Raman signal. The Raman bands at position 480, 633 and 670 cm -1 that were identified as Ca 2 Sb 2 O 7 and CaSb 2 O 6 [32], respectively, show a higher intensity at the outer side of the sample compared to the inner part, but no gradual decrease in intensity is observed moving toward the inner part of the sample. These results, as shown in Fig.…”

The combined use of handheld energy-dispersive X-ray fluorescence spectrometry, Raman spectroscopy, and micro-energy-dispersive X-ray fluorescence spectrometry permitted the characterization of Roman glass tesserae excavation from the Coriglia (Italy) archeological site. Analyses of ten different glass colors were conducted as spot analyses on intact samples and as both spot analyses and line scans on select cross-sectioned samples. The elemental and molecular information gained from these spectral measurements allowed for the qualitative chemical characterization of the bulk glass, decolorants, opacifiers, and coloring agents. The use of an antimony opacifier in many of the samples supports the late Imperial phasing as determined through numismatic, fresco, ceramics, and architectural evidence. And dealinization of the exterior glass layers caused by the burial environment was confirmed.

“…A very intense and narrow signal at 466 cm −1 associated with peaks at 143, 206, 355 and 394 cm −1 is due to quartz (Fig. 3 (e)), found in all the investigated samples, and typical for quartz in free and isolated form [6,34]. Brandis samples show weak peaks at 807 and 961 cm −1 attributed to dehydroxylated kaolinite not completely transformed into metakaolinite, which has disordered structure and a broad and weak Raman signal [35].…”

Glass has been produced and used since ancient times because of its malleability at moderate temperatures and its more or less pronounced optical clarity. The latter characteristic makes optical spectroscopic methods ideally suited for its study. Glass has not only been produced to make glass artefacts, in fact the largest range of glass compositions was prepared by potters in order to coat pottery with glazes and to apply complex enamelled coatings to make porous ceramic bodies impermeable or for decorative purposes. Enamels have also been deposited on metals, mainly copper and its alloys, since the earliest times. All of these uses require the preparation of glass compositions ranging from a high silica content (typically 11 SiO 2 , ∼1 K 2 O for porcelain glazes melting at ∼1400 • C) to a low-melting lead-rich glass (PbO−SiO 2 ) with a melting temperature below 600 • C [1].All applications in the science, art and technology of glasses, glazes and enamels consist of a controlled modification of the three-dimensional Si−O network by replacement of Si 4+ covalently bonded atoms by noncovalently bonded atoms, hence decreasing the number of Si−O bridges and the connectivity of the network, that is, modifying the glass nanostructure. Consequently, the melting temperature decreases and many other physical/chemical properties related to the density and network connectivity, such as thermal expansion, chemical resistance, and so on are modified accordingly. This was performed more or less empirically by glass-makers by mixing a glass former, namely silica, with low-melting temperature compounds, such as soda-or potash-rich materials. Grinding the materials is the most difficult aspect in preparing ceramics and glass batches, and therefore ancient glassmakers and potters used natural fine silica powders (fine sand or roasted flint pebbles crumbled by dipping in water) as glass formers and some fine-grained minerals, shells Modern Methods for Analysing Archaeological and Historical Glass, First Edition.
