What is the distinction between glass transition temperature and melting temperature?

Glass transition temperature is a characteristic of soda lime glass and melting temperature is for a Borosilicate glass.

Explanation:

The glass transition is the change of an amorphous solid from soft and flexible to glass-like, i. e. hard and brittle. On the other hand, the melting temperature is the temperature at which the liquid - solid phase transition occurs in a crystalline substance.
