Before going to the quartz countertops, let’s start with quartz. Quartz is one of the most important minerals in rock composition. Almost all the rocks contain quartz. Based on the color the quartz can be named or classified into many types the synonyms are also based on the color. The chemical composition of quartz is SiO2 (silica: silicon dioxide) The quartz can be found in many looks they are called polymorphism, which are cristobalite, tridymite, coesite, and stishovite. The common property of quartz is the crystallographic system which is trigonal, occasionally pseudo-cubic.

Quartz can be found in many places and the main  genetic environments are;

So far there is no specific type of locality from where quartz can be identified.

The quartz  can stay in many associated minerals: they are as native Bismuth, Calcite, Chlorite, Epidote, Feldspars, Fluorite, Micas, Zeolites. Quartz  sometimes can be difficult to identify because of the optically similarity with the Coesite, Cristobalite, Lechatelierite, Melanophlogite, Melano- phlogite-β, Moganite, Opal, Stishovite, and Tridymite. The dominant reflection of colour is dark grey.

The Rreflectance (%) of quartz is 5. The opacity/diaphaneity is transparent to nearly opaque.

Internal  reflectance of quartz is almost clear, milky, brilliant (anomalous interference colours). The common habits of quartz is large prismatic crystals (m-scale), massive. The quartz is very hard mineral and for this reason it can be used as a quartz countertops. The average hardness of quartz is 7.

10% Quartz is used for the manufacture of quartz countertops.

The application of quartz are many. The quartz can be used as a gem stone or kitchen staff like quartz kitchen countertops (Photo from The quartz countertops are one of the rising design stye in the kitchen or in the home or shopping mall decoration. The one of the best countertops are quartz kitchen countertops.

Lets discuss about the quartz countertops for your kitchen as an application of the quratz.

What is the quartz countertops?

Quartz countertops are one of the engineered materials made by quartz mixing some other minerals in it and bounded the particles by resins. The quality of quartz countertops depends on the percentage of rasin added, 7% rasin makes the higher quality and more than 10% rasin makes low quality of quartz countertops.

Quartz countertops is less porous and more durable kitchen sinks.

Quartz countertops are not made completely solid  quartz  because it is made by the mixture of some other small grain minerals in it like garnet, and other silicate minerals. But the amount of pure quartz is present of course only 10% . The quartz countertops is called the engineered stone. It is made by the factory.


The first quartz countertops factory in the world:

All the quartz countertops are initially stated from the Breton company in 1963 by the trademark of Bretonstone (R) and still they produce the high quality quartz countertops.  The process involved the blending pulverized the natural stone aggregated with the mixture of other minerals and removing the air then heating and shaping the slabs that look like natural stone produced the quartz countertops. Then Bretonstone technology allow to provide the licensed more than 50 companies around the world including the famous brands of Silestone, Cambria, Caesarstone etc.

Quartz countertops are environmental friendly:

After mined (quarry) the natural stone from the mining some by-products are produced from the extracting process. This by-products of natural stones are used for the quartz countertops. No natural fresh stone is used in the quartz countertops manufacturing process. Hence it is called the eco-friendly natural countertops.


Quartz is more durable and look good less porus enhances the room beauty as it has the multiple color of design. The granite as a countertops use in the kitchen is widely used. The quartz countertops play a good role for the decoration and fashion.

The price for the quartz countertops are $15 to $70 per square feet on avarage. The graniate countertops are $15 to $140 per square foot.

The cheaper option for the kitchen countertops are also available in the market; laminate costs on average $8 to $27 per square foot, and wood or butcher block costs $10 to $38 per square foot. Porcelain or ceramic tiles are also inexpensive countertop $3 to $28 and $1 to $15 per square foot respectively.
