Uses of Quartz in Glass Making

Geological processes have occasionally produced sands that are virtually entirely comprised of quartz grains. These deposits have been discovered and developed as a supply of high quality silica sand. These sands are utilised in the glass manufacturing process. Container glass, flat plate glass, speciality glass, and fibreglass are all made from quartz sand.

Quartz glass sand: A high-purity quartz sandstone used for the manufacture of quality and strong glass. Glass sand is a kind of sandstone that is nearly completely composed of quartz grains. In a few places, the Oriskany is more than 99 percent pure quartz. Much of it has been used for container glass, but some of it has been chosen for use in the manufacture of lenses for the world’s greatest telescopes. The specimen is around four inches long (10 cm across).

Uses of Quartz as an Abrasive

Quartz has a Mohs hardness of 7, making it harder than most other natural solids. As such, it is an excellent abrasive. Sandblasting, scrubbing cleansers, grind media, and grit for polishing and sawing all employ quartz sand and grinded silica sand.

Uses of Quartz as a Foundry Sand

Quartz is extremely resistant to chemicals and heat. As a result, it is frequently utilised as foundry sand. It has a greater melting temperature than other metals and may be used for moulds and cores in routine foundry operations. Because of its excellent heat resistance, quartz sand is frequently used to make refractory bricks. Quartz sand is also utilised as a flux in metal smelting.

Silicified “petrified” wood is created when buried plant waste is penetrated by mineral-bearing fluids that precipitate quartz. This quartz fills the holes in the wood and, in certain cases, replaces the woody fibres. This specimen is from Yuma County, Arizona, and is around four inches (ten cm) across.
