What is Glass?

Glass is an amorphous (non-crystalline) solid material that is often transparent and has widespread practical, technological, and decorative uses in everyday objects. It is formed by cooling a molten material, such as silica, rapidly to prevent crystallization.

Types of Glass

There are several types of glass, including soda-lime glass (most common type used in windows and bottles), borosilicate glass (known for its heat resistance), tempered glass (treated to increase its strength), and colored glass (which contains various metal oxides to give it color).

Properties of Glass

Glass is known for its transparency, hardness, and ability to be molded into various shapes. It is also a good insulator, meaning it does not conduct heat or electricity well. However, it is brittle and can break easily under pressure.

Uses of Glass

Glass is used in a wide range of applications, including windows, containers, lenses, fiber optics, laboratory equipment, and artistic decoration. It is also used in construction for its transparency and ability to let in light while providing a barrier from the elements.
