How is glass made naturally?
In nature, glasses are formed when sand and/or rocks, often high in silica, are heated to high temperatures and then cooled rapidly. The Glass in Nature display shows specimens of glass made in nature. Obsidian or volcanic glass, for example, is molten rock that has quickly cooled, becoming rock in a glassy state.
Is Glass expensive to produce?
While the cost of producing bottles can vary depending on the raw material and energy prices at the time, it is generally not that much more expensive to produce a glass bottle versus one made from PET – about $0.01 more, according to some analysis.

The raw materials that float glass is made up of are: SiO2 – Silica Sand. Na2O – Sodium Oxide from Soda Ash. CaO – Calcium oxide from Limestone / Dolomite.
How do you classify glass?
In general you can divide glass into two groups: natural glass and artificial glass. While artificial glass is produced by the melting of several raw materials, natural glass is produced by processes in nature. The best known of such processes has to be the formation of obsidian and pumice.
What is the glass?
