Ideal glass transition using silicate glass through the evolution of intermediate-range orders

An ideal glass is a hypothetical model introduced for glasses that satisfies the third law of thermodynamics. We realized an ideal glass using silicate glass during prolonged aging below the Kauzmann temperature TK, which had the dissipative structure to be ordered. The silicate glass exhibited enthalpy recovery to take an ideal glass and structure recovery to approach a polycrystalline ground state over an extremely long time. The physics of structural glasses was discussed as the thermodynamics of glass through the evolution of intermediate-range orders in which the cage effect, bifurcation phenomenon, annealing, and phase transition were studied. Structure recovery is a local phase transition of glass toward the ground state. This is a novel process of glass with negative entropy production, which works in living things. An ideal structural glass corresponds to the Ising spin glass introduced by Parisi. This theory is based on thermodynamics for a far-from-equilibrium system with an extremely long relaxation time to generate a new ordered state.
