“…[38]. Figure S1 shows the Raman spectra of the sample indicated in Table 1, which exhibit the peculiar band shape of SiO 2 and the sodium silicate glass systems [28,31,33,39,40]. Indeed, when sodium is added to the silica matrix, the R band dramatically decreases and a new band appears, namely the R c band.…”

The temperature and chemical dependence of the melt viscosity are ubiquitous in the model development of the volcanic dynamics, as well as in the glass production and design. We focussed on the yet-explored relationship between the bulk and shear moduli ratio and boson peak with the melt fragility of their parental glasses. Here, we explored the extension of the observed trend by testing the conventional binary system Na2O-SiO2, thus providing new evidence supporting the link between the flow of melts and supercooled liquids and the vibrational dynamics of their parental glasses. This was accomplished by integrating new low-frequency Raman measurements and integrating data from the literature on Brillouin light scattering and viscometry. This approach allows us to feed the MYEGA equation with reliable input parameters to quantitatively predict the viscosity of the Na2O-SiO2 system from the liquid up to the glass transition.
