From: Ultrastable glasses portray similar behaviour to ordinary glasses at high pressure

HP-DTA signal as a function of temperature for different pressures, in MPa, as indicated in both figures, measured on heating at 2 K/min.
(a) Ultrastable IMC glass grown from the vapour phase at a substrate temperature of 0.85Tg. (b) Conventional glass formed by cooling the liquid at 2 K/min. The curves at atmospheric pressure correspond to specific heat measured by DSC. The onset temperature of devitrification is calculated as indicated by the red lines in the figure. The curves have been shifted vertically for clarity.
