The glass transition temperature, <math>T_g</math>, is the temperature at which an amorphous solid transitions continuously into a liquid state, and vice versa. There are several definitions of this temperature, detailed by Debenedetti and Stillinger [1]:
1. In a plot of volume versus temperature, the intersection of the liquid and glass curves marks <math>T_g</math>. 2. Temperature at which the material viscosity reaches <math> 10^13</math> poise.
