“…W. H. Zachariasen 50 had investigated the silicate glasses and he found that such glasses are consist of silicon tetrahedrally coordinated to 4 oxygen atoms [6]. The silicate glasses were investigated in presence of Na 2 O, Li 2 O, K 2 O and CaO by various research groups [16][17][18][19][20][21][22][23][24][25]. Price et al [7].…”

“…A sharp band at 133 cm -1 in the 2 mol% Mocontaining lead borate glasses was found. The peaks for 25 heavy metal oxides are assigned in the range 380 -580 and 650 -950 cm -1 due to the bridging anion modes and the non-bridging anion modes, respectively. This suggests the presence of Pb 2+ in high lead borate glasses in the form of PbO 4 groups.…”

This article examines the influence of the composition on the Raman spectra of lead silicate glass. Modern and historic lead alkali glasses and high-lead glazed ceramics were analysed complementarily by Raman spectrometry and elemental techniques, either electron microprobe, proton induced X-ray emission (PIXE) or scanning electron microscope with energy dispersive spectrometry (SEM-EDS). The results showed that lead alkali silicate and high-lead silicate glasses can be easily distinguished from their Raman spectra profile. In lead alkali silicate glasses, continuous variations were observed in the spectra with the compositional change. In particular, the position of the intense peak around 1070 cm −1 was linearly correlated to the lead content in the glass. A unique decomposition model was developed for the spectra of lead alkali silicate glasses. From the combination of the Raman and elemental analyses, correlations were established between the spectral components and the composition. These correlations permitted to interpret the spectra and access additional compositional information, such as the lead content from area ratio A 990 /A 900 -1150 , the total alkali + alkaline-earth content from the area ratio A 1100 /A 900 -1150 or the silica content from the area ratio A 1150 /A 900 -1150 . In lead silicate glass containing over 25 mol% PbO, the compositional variation induced no variation in the SiO 4 network region of the Raman spectra [150-1350 cm −1 ], therefore no correlations and compositional information could be gained from the glass spectra in this range of composition. This new development of Raman spectroscopy for the analyses of glass will be very valuable for museums to not only access compositional information non-destructively but also to understand the structural changes involved with their alteration.
