Granite is a hard, coarse-grained igneous rock that forms from the slow cooling of magma deep underground, making it a plutonic rock. It primarily consists of minerals like quartz, feldspar (which gives it color), and mica, along with smaller amounts of other minerals. Its grainy appearance is due to the visible, interconnected crystals of these minerals.  Key Characteristics

• Igneous Rock: Granite forms from molten rock (magma) that cools and solidifies beneath the Earth's surface. 
• Coarse-Grained: The minerals in granite are large enough to be seen with the naked eye, giving it a characteristic "grainy" texture. 
• Mineral Composition: It is composed mainly of quartz and feldspar, with mica, hornblende, and other minerals often present. 
• Colors: The color of granite varies, often being white, pink, grey, or brown, depending on the type and proportion of its feldspar minerals. 
• Plutonic Rock: Because it solidifies underground, it is classified as a plutonic rock.

Where It's Found

• Granite is the most common plutonic rock in the Earth's crust.
• It is frequently found in the continental plates of the Earth's crust, sometimes exposed through geological processes like tectonic movement. 

Composition Granite is primarily composed of light-colored minerals, which give it a speckled appearance. Its main mineral components include: 

• Quartz: Usually gray or milky white, this mineral makes up 20% to 60% of the rock by volume.
• Feldspar: This is the most abundant mineral group in granite. The type of feldspar present largely determines the granite's color, which can range from pink or red (potassium feldspar) to white or gray (sodium-rich plagioclase feldspar).
• Mica: In smaller amounts, minerals like biotite (dark brown or black) and muscovite (metallic gold or yellow) add dark flecks and sparkle to the rock.
• Other minerals: Trace amounts of other minerals, such as amphiboles like hornblende, can also be present.

FormationThe process of granite formation can take millions of years and involves several steps: 

1. Magma Genesis: Intense heat and pressure deep within the Earth's crust or mantle partially melt existing rock to form magma.
2. Magma Ascent and Intrusion: This silica-rich magma is less dense than the surrounding rock and slowly rises, collecting in large, underground chambers called batholiths.
3. Slow Cooling and Crystallization: Insulated by the surrounding rock, the magma cools very slowly. This gradual process allows for the growth of the large, interlocking mineral crystals that give granite its characteristic coarse-grained texture.
4. Uplift and Erosion: Over millions of years, the rock is brought to the surface through geological uplift and the erosion of the overlying material. This exposes the granite in mountain ranges and rocky outcrops.

PropertiesGranite possesses a number of desirable physical properties that make it useful for many applications: 

• Hardness: With a Mohs hardness of 6 to 7, granite is very hard and resistant to abrasion and scratching.
• Durability: Its interlocking crystal structure makes it extremely tough and durable, capable of withstanding significant wear and exposure to the elements.
• Weather Resistance: Granite is resistant to both physical and chemical weathering, meaning it holds up well over time.
• Heat Resistance: The stone can handle high temperatures without damage, making it ideal for kitchen applications.
• Low Porosity: Granite has low porosity, which makes it resistant to staining when properly sealed.
• Density: The rock has a relatively high density, ranging from 2.65 to 2.75 g/cm³.

Common usesThe strength, durability, and aesthetic appeal of granite make it a popular material for a wide variety of uses: 

• Countertops and Tiles: Its heat resistance and durability make it a premium choice for kitchen and bathroom surfaces.
• Flooring: In both residential and commercial buildings, polished granite tiles are used for their elegance and resilience.
• Monuments and Buildings: Due to its ability to endure weathering for centuries, it is used for public buildings, monuments, and gravestones.
• Construction: Crushed granite is used as a base material in road construction, and larger blocks can be used for building exteriors and curbing.
• Decorative Purposes: Used in sculptures, fountains, and other ornamental applications.

Process Of Granites

Step 1: Quarry

Quarry or Mines is a place to dig underground the granite rocks. This is a complete process of drilling, blasting, with specialized equipment's to bring out composites of granite. These composites called rough blocks and later it will convert in the dressed blocks by wire saw machines. We produce high quality blocks with specialize & experienced team who well versed to use pioneering styles of quarrying.

Step 2: Processing

After the blocks are extracted from the quarry, they'll go through further processing to match their intended purpose. Thereafter rough blocks take shape from wire saw dressing machine and become ready to cut in Gaspari gang saw, which uses multiple diamond-tipped blades to slice a granite block into manageable slabs. Our highly skilled team are well managed to keep clients satisfy by maintaining quality and production parameters.

Step 3: Polishing

Marble / Granite Slab Polishing is done by Machine using rotating abrasives on special plates held by rotating spindles. An automatic bridge which moves transversally over the slabs and houses all the spindles and relevant abrasive heads move the abrasives over the slab. Different types of Finishing Options are available like Leather, Flamed, Brushed, Polished, Honed, Lapatura etc.

Step 4: Warehouse

We can supply more than 150 colors under one roof, we have a textures that allow you to create a style especially for you. We specialize in the fabrication, installation, and custom design of Granite, Marble & Sandstone. Our capacity drives by our hi tech installed machines, breton line polisher, gaspari gangsaws, wire saw, resin line etc.
