Glass

Glass is an inorganic liquid material which has solidified and become rigid without forming a regular crystalline structure. Instead it has a random, liquidlike (non-crystalline) molecular structure, whose atoms are frozen in position. Thus, glass "freezes" the atomic structure of the liquid.

The manufacturing process requires the raw materials to be melted, and then cooled rapidly.

Glasses are generally hard, perfectly elastic, and brittle. They are transparent but refract the light and are electrical insulators as well as being very resistant to corrosion and ageing.
