Glass is manufactured primarily from the mineral quartz (SiO2) which is what sand is made from.
However small amounts of other minerals are added to the sand to make the process easier. These minerals are:-
sodium carbonate (Na2CO3)
lime (calcium oxide (CaO)
magnesium oxide (MgO)
aluminum oxide (Al2O3)
There are also other minerals which are added to make specialised glasses. e.g. Pyrex glass is made from sand and boron oxide.
The miniral used in glass is primarily silicon.
Silica sand is the main ingredient in common glass.
There could be several rocks used in the making of glass, but the main constituent material used in making glass is quartz. The rock which is used most for supplying the quartz used in glass making is sandstone.
Gypsum
The two main constituents of glass are : Silicon Dioxide , Sodium Carbonate. Alumina or borosilicate are added depending on the nature of the glass required. Glass is a 'supercooled' liquid. , that is a liquid below its natural freezing point. Supercooled liquids do not have a crystalline structure, which pure solids have. However, glass if left for long periods of time (hundreds of years) may start to 'cloud', this is the crystals forming from the supercooled liquid.
Iron (Except Iron isn't a mineral. Iron is an element. The MINERAL and principal ore from which Iron is taken is GALENA.)
Gypsum.Gypsum is a sulfate mineral that is mostly used for wallboard (sheet rock) and plaster products. It also is used for cement production, agricultural applications, glass making, and other industrial processes.
phosphate
Borax
boron (borax)
Sand heated to a very high temperature.
A white mineral in some alkaline salt deposits, used in making glass and ceramics, as a metallurgical flux, and as an antiseptic.
borax
Sand heated to a very high temperature.

Microcline
Computer chips are made with Silicon (metal). Glass, however, is made from Silica (sand) which sounds similar, but is actually quite different.
