Detailed explanation-1: -Glass is made from natural and abundant raw materials (sand, soda ash and limestone) that are melted at very high temperature to form a new material: glass. At high temperature glass is structurally similar to liquids, however at ambient temperature it behaves like solids.

Detailed explanation-2: -Glass is made by melting together several minerals at very high temperatures by sodium and calcium silicate. Silica in the form of sand is the main ingredient and this is combined with soda ash and limestone and melted in a furnace at temperatures of 1700°C.

Detailed explanation-3: -Basically glass is the homogenous mixture of the silicates of various alkaline metals of non-crystalline and transparent or less transparent substances. Ordinary glass is manufactured by the composition of various substances like silica, bleaching powder, oxides of alkaline metals, calcium oxide (lime) etc.

Detailed explanation-4: -Sand (SiO2 silica) In its pure form it exists as a polymer, (SiO2)n. Soda ash (sodium carbonate Na2CO3) Limestone (calcium carbonate or CaCo3) or dolomite (MgCO3)
