What makes a glass different from a solid such as quartz? Under what conditions could quartz be converted into glass?

Explanation

Glass is an amorphous solid in which the constituent particles (`SiO_(4)` tetrahedra) have only a short range order and there is no long range order. In quartz, the constituent particles (`SiO_(4)` tetrahedra) have short range as well as long range order. On melting quartz and then cooling it rapidly, it is converted into glass.
