17/6/2020And it is this demand for silica sand (SiO2) that might prove to be a bit of a stumbling block. While silica sand is the most abundant mineral on the planet, it is still a finite resource. This is because high purity sand is required for making both flat glass and container glass as impurities such as sulphides and iron will cause imperfections.

Silica Sand — Glass Composition and Why Silica Matters. Silica sand is the main component in glass production. While industrial glass production and other forms of glass making also make use of up to 30% other materials for the final composition of glass, the silica quartz structure allows for the right combination of hardness, heat resistance, and coloration.

The natural silica sand is the most preferred material in a glass industry, but in some cases where the glass plants are located far away from silica deposits, crushed quartz is also used. For use in glass industry the silica sand must be uniform in chemical composition, size and shape of grains. Uniform grain size, promotes even melting in the glass tank. The sand should not be coarser than

SILICA SAND is one of the world's most common sand types. Silica sand is used for construction, glass making, filling and for the development of moulds and castings. Sands is the general term for broken mineral or rock granules which fall between slats and gravity in the range of sizes and are generally between one sixteenth of a millimetre and two millimetre in diameter.

One of the first to use silica sand is the glass industry. At least 4000 years ago, long before iron was smelted, glass-making was already a known craft. The oldest known specimens of glass was obtained from Babylon (2600 B. C.) and from Egypt (2500 B. C.). It could be conclusively proved that the glass-making was well established in these countries by around 1500 B. C. (IBM, 1993) The silica
