How is quartz formed in nature?

The beautiful crystals of quartzbetter known to enthusiasts as rock crystal, form in the cracks of siliceous rocks by a process called “hydrothermal”. Indeed, water under high pressure and at high temperature has the power to partially dissolve silica.

How do crystals form in nature?

The crystals form either by cooling molten minerals, or magmas, gaseous minerals or fumaroles (minerals formed at high temperatures); or from hydrothermal solutions (low temperature minerals).

Where does quartz form?

Basically: The beautiful crystals of quartzbetter known to enthusiasts as “rock crystal”, form in the cracks of siliceous rocks by a process called “hydrothermal”.

How to create crystals?

Crystal growth: the formation of crystals. For one crystal may to form, a chemical element must be brought into contact with a liquid solution, usually water, and must be able to evolve under favorable conditions (temperature, pressure, evaporation time).

How does quartz grow?

The conditions under which these crystals appeared have been studied for more than a century: to grow forming such elegant crystals, the quartz needs space, therefore a crack in the rock, and liquid rich in dissolved silica which circulates there.

What are the constituents of quartz?

It comes in the form either of large colorless, colored or smoky crystals, or of microscopic crystals with a translucent appearance. Constituting 12% (by mass) of the lithosphere, quartz is the most common mineral (oxygen and silicon are the first and second constituents respectively,…

What are the uses of quartz?

Quartz is used in many fields: 1 the production of industrial floors (anti-wear); 2 water purification; 3 industrial sandblasting; 4 decorative material (parks, paths, car parks, etc.); 5 development of golf courses (bunkers); 6 watchmaking; 7 jewelry.

What is the color of quartz?

In northwestern Quebec, quartz is one of the main indicators of the presence of gold in its mass. Its color is mainly milky white or pale gray. Artificial quartz single crystal made by hydrothermal method (19.2 × 2.8 cm).

What is Quartz?

Quartz is a mineral made up of crystallized silica (rhombohedral structure) and present in a pure state (sometimes with a translucent appearance in rock crystal, most often opaque) or as a constituent of granites, sandstones or even sands. Pure, it can be colorless or colored by impurities (amethyst, citrine).
