A supercooled liquid is a state in which a liquid does not crystallize even when cooled below its melting point, but instead solidifies while retaining its liquid structure.
Glass is formed when this supercooled liquid freezes; it does not have a distinct melting point and becomes progressively softer as the temperature rises. This is why glass is called a “solid liquid.”
