how it is formed?
For melt quenching, if the cooling is sufficiently rapid then crystallization is prevented and instead the disordered atomic configuration of the supercooled liquid is frozen into the solid state at T. The tendency for a material to form a glass while quenched is called glass-forming ability.

For melt quenching, if the cooling is sufficiently rapid (relative to the characteristic crystallization time) then crystallization is prevented and instead the disordered atomic configuration of the supercooled liquid is frozen into the solid state at T. The tendency for a material to form a glass while quenched is called glass-forming ability. This ability can be predicted by the rigidity theory.
name two articles that can be made from glass Window panes and tableware. how can you describe its microscopic structure? Although the atomic-scale structure of it shares characteristics of the structure of a supercooled liquid, glass exhibits all the mechanical properties of a solid. As in other amorphous solids, its atomic structure lacks the long-range periodicity observed in crystalline solids. Due to chemical bonding constraints, they do possess a high degree of short-range order with respect to local atomic polyhedra.

Glass [SEP] Formation from a supercooled liquid
For melt quenching, if the cooling is sufficiently rapid (relative to the characteristic crystallization time) then crystallization is prevented and instead the disordered atomic configuration of the supercooled liquid is frozen into the solid state at T. The tendency for a material to form a glass while quenched is called glass-forming ability. This ability can be predicted by the rigidity theory. Generally, a glass exists in a structurally metastable state with respect to its crystalline form, although in certain circumstances, for example in atactic polymers, there is no crystalline analogue of the amorphous phase. Glass is sometimes considered to be a liquid due to its lack of a first-order phase transition where certain thermodynamic variables such as volume, entropy and enthalpy are discontinuous through the glass transition range.
