Glass is an amorphous (non-crystalline) solid made from sand that displays a glass transition near its melting point which is around 1,700°C (3,090°F). This means that material transforms from a hard and brittle state into a molten state, or vice versa depending on whether the glass transition temperature is the melting or solidifying point. An amorphous solid has some of the crystalline order of a solid and some of the random molecular structure of a liquid.
Silicate glass is the most common form, which consists mainly of silica or silicon dioxide, SiO2. Impurities or additional elements and compounds added to the silicate change the colour and other properties of the glass.
Glass is a very commonly used material because, whilst still molten, it can be manipulated into forms suitable for a very wide range of different uses, from packaging and household objects to car windscreens, windows, and so on.
