Glass is characterized as a hard, brittle, translucent, and commonly transparent substance, white or colored, having a conchoidal fracture, and made by fusing together sand or silica with lime, potash, soda, or lead oxide. It is used for window panes and mirrors, for articles of table and culinary use, for lenses, and various articles of ornament.

Glass is described as a hard, brittle, generally transparent or translucent material typically formed from the rapid cooling of liquefied minerals. Most commercial glass is made from a molten mixture of soda ash, sand, and lime.

The term glass is used to denote all materials whose chemical structure is similar to that of a liquid, but whose viscosity at a normal temperature is so high that they can be described as solids.

Mineral glass is obtained by overcooling a melt and is hence also often described as an overcooled liquid. In actual fact, glass is not a solid but even in its solid state displays a certain viscosity which is not noticeable in everyday use.
