  Differential scanning calorimetry (DSC) is one of the most versatile probes
for silicate glasses, allowing determination of, e.g., transition temperatures
(glass, crystallization, melting) and the temperature dependence of heat
capacity. However, complications arise for glasses featuring overlapping
transitions and low sensitivity, e.g., arising from SiO2-rich compositions with
small change in heat capacity during glass transition or the low sensitivity of
thermocouples at high temperature. These challenges might be overcome using
temperature-modulated DSC (TM-DSC), which enables separation of overlapping
signals and improved sensitivity at the expense of increased measurement
duration.
