“…The spectrum of Pb‐free Na 2 SiO 3 glass shows a considerable overlap between Na‐NBO (Na‐O‐Si, a narrow feature at ~35 ppm) and BO (Si‐O‐Si, a broad feature). The observed peaks were assigned based on the previous 17 O NMR studies for Na 2 O‐SiO 2 glasses 55,59,66,68,72,73,84 . The peak position and width of MAS NMR spectrum for Na 2 SiO 3 glass in the current study are consistent with the previous NMR studies (e.g., 59,66,73 ).…”

“…Even though iron abundance varies in different natural silicates, it remains present in amounts that can significantly influence their physical properties. In natural magmatic melts, the iron oxide concentration ranges from~0.5 wt % in rhyolitic melts to~20 wt % in basalts [Kim et al, 2016;Mysen and Richet, 2005]. It has been known that natural silicate melt properties are strongly influenced by iron content, since iron occurs in two valence states (Fe 2+ and Fe 3+ ) with different oxygen coordinations (four-, five-, and sixfold) which affect physical properties and crystallization of magmas [Brearly, 1990;Di Genova et al, 2016;Magnien et al, 2004Magnien et al, , 2008.…”
