3.2. DSC Characterization and Physical Properties The presented DSC data (Figure 7, Figures S6–S10, Table 3) led us conclude that for the glasses of this system, the glass transition temperature (Tg) decreased with PbCl2 content growth. For the boundaries of PbCl2 composition, the difference was 80 °C. Such a significant change in the glass transition temperature (Tg) has been observed by other researchers and was attributed to structural changes in the glass network [16,48,49].
