glass transition

Physics

The transition that occurs when a liquid is cooled very rapidly to become a glass. The glass transition temperature of a material is not a clear-cut temperature like the melting point. This is the case because the glassy state is a metastable state, with the transition temperature becoming lower as the rate of cooling decreases. The freezing temperature for a material is always higher than the glass transition temperature for that material. The theory of the glass transition is much more complicated than the theory of normal phase transitions.

Chemistry

The transition between a glass and a liquid. This transition, which can be reversed, is not a phase transition, as it occurs over a temperature range rather than at a particular temperature. The glass transition has turned out to be a very difficult problem to analyse theoretically. In spite of a great deal of effort over many years it is not well understood.
