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.
quartz used for making glass
borax
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 mineral quartz is the main ingredient in manufactured glass.
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.
No. A mineral must be solid to be a mineral. For example, liquid water is not a mineral. Frozen water, or ice, is a mineral.
phosphate
Borax
boron (borax)
phosphate
A white mineral in some alkaline salt deposits, used in making glass and ceramics, as a metallurgical flux, and as an antiseptic.

Microcline
Computer chips are made with Silicon (metal). Glass, however, is made from Silica (sand) which sounds similar, but is actually quite different.
I would think that the answer is simple and resides in the simple business economic laws of supply and demand. The supply of glass for recycling is abundant whereby the material for making mineral glass countertops must be brought in and processed before making it into a countertop.
