Quartzite

Quartzite is a type of metamorphic rock that is formed from the transformation of sandstone when subjected to high heat and pressure beneath the Earth's surface. This process causes the sand grains within the sandstone, which are predominantly quartz mineral, to melt, recrystallize, and fuse together, resulting in a very dense and strong rock.

Key Features

• High Hardness: With quartz as its main component, which has a hardness of 7 on the Mohs Hardness Scale, quartzite is highly resistant to scratches. Even a knife blade cannot easily scratch it.
• Heat Resistance: It can withstand heat well, making it suitable for use in areas exposed to heat, such as kitchen countertops.
• Low Porosity (compared to sandstone): The metamorphic process makes the rock denser, reducing porosity. However, as it is still a natural stone, sealing the surface is recommended to prevent deep-set stains.
• Beauty: It comes in a variety of patterns and colors, ranging from white and gray to vibrant shades like green, blue, pink, or red. The patterns often feature veining similar to marble but with greater strength.

Generally, quartzite is not divided into distinct geological "types" like other kinds of stone. Instead, the variety in quartzite comes from:

• Color and Pattern: These depend on other minerals present in the original sandstone before its metamorphosis and the geological processes that occurred. This results in different colors and patterns in each slab, ranging from thin mineral veins to complex and striking (exotic) patterns. For example, Avocatus quartzite has a deep green color with green and white veins.
• Origin: Quartzite from different sources around the world may have unique characteristics.

Therefore, selecting a "type" of quartzite usually focuses on choosing colors and patterns that meet design requirements, rather than classifying it by geological type.

With its outstanding properties, combining both beauty and durability, quartzite is used in a wide variety of applications.

• Countertops: It is highly popular for kitchen and bathroom countertops due to its scratch resistance, heat resistance, and beautiful appearance.
• Flooring and Walling: Suitable for both interior and exterior applications, it adds luxury and durability.
• Other Decorative Works: Such as coffee tables, dining tabletops, decorative headboard walls, column cladding, or even swimming pool surrounds (it is advisable to consult with specialists regarding surface coating and maintenance).
• Other Industries: Industrially, it may be used to make sharpening stones or as a component in the glass industry.

• Determine the purpose of use: Choose stone appropriate for the area. For example, kitchen countertops require high durability, while outdoor areas need weather resistance.
• Choose colors and patterns: Consider colors and patterns that match the overall decoration style. You should view the actual stone slabs, as each natural stone slab is unique.
• Inspect the quality: Observe the thickness, color consistency (if desired), and any potential cracks.
• Consider your budget: Quartzite often has a higher price than some types of granite or marble due to its strength and unique patterns.
• Choose a reliable supplier: You should buy from a specialized dealer who offers good installation services and may provide a warranty for the product during transportation and installation.

Installation

• Should use expert technicians: The installation of natural stone, especially large and heavy slabs like quartzite, should be done by experienced technicians to ensure standardized cutting, pattern matching, and grouting, and to prevent cracking or damage.

Maintenance

• Daily Cleaning: Wipe clean with a soft, damp cloth or use a stone-specific cleaner that is pH neutral (avoid highly acidic or alkaline solutions such as toilet bowl cleaners or concentrated detergents).
• Managing Spills: Because natural stone is porous, spills such as coffee, wine, or oil should be wiped up immediately to prevent deep staining.
• Sealing: Quartzite should be treated with a sealant to help reduce water absorption and protect against stains. Consult with the installer or supplier regarding the frequency of re-sealing, which may be every 1-2 years or depending on usage conditions.
• Removing Scratches: Although durable, if deep scratches occur, it may require a professional technician to polish the stone surface to remove the marks.
• Avoid Harsh Chemicals: Do not use cleaning agents with strong corrosive properties or very abrasive scrubbing materials, as they can damage the stone's surface.

Proper care will help keep your quartzite beautiful and ensure its longevity.
