In India when most people heard the word “granite” the 1st thing that comes in your mind is kitchen platforms, Window framings, Door
framings, Staircases, etc. However, there is a reason why granite is the preferred
material for Indian kitchens. The stone surface not only adds a natural and
elegant look to the kitchen but is also the most functional and long-lasting
solution for our kitchens. After all, it’s one of the toughest materials that
can withstand our special and intense cooking style (whether it’s with
stain-prone spices like turmeric or heavy items like mortar and pestle,
pressure cookers, and so on).

One of the most common countertop materials is granite. It
was first used in luxury homes in the 1920s, but it did not become a popular
approach until the 1970s. It was still regarded as high-end interior design
material, and many homeowners believed it was out of their price range. Granite
technology and transportation advances were introduced in the 1990s, allowing
mass production, and it became a backbone in middle-class homes around the
world.

Homeowners looking to renovate their homes often consider
adding a beautiful stone element. Many people recognize elegance and usefulness
when selecting the right stone, but they neglect the scientific specifics of
each stone.
Knowing the source of granite may seem unnecessary for a
renovation project, but it can make your new renovation feel much more exciting
when you learn about the years of scientific miracles that came together to
create the beautiful material. So we’ll see how granite shapes up before it
gets to the Outlets.

How Granite Forms?

Granite is a naturally occurring rock formed deep within the
Earth’s surface over millions of years. The granite is known as an Igneous
Rock, which is derived from the Latin word “Ignis,” which means
“fire. Igneous rocks can develop in two ways, Igneous rocks are formed as
a result of the cooling of lava or magma in general. The molten rock substance
under the surface is referred to as magma, while the molten rock substance
above the surface is referred to as lava. This phase’s location decides whether
an igneous rock is intrusive or extrusive.

As lava flows from a volcano and solidifies into extrusive igneous
rock, also known as volcanic rock, it cools very easily. Crystals within solid
volcanic rocks are small because they do not have much time to shape until the
rock cools completely, stopping crystal growth. Crystals are so tiny that they
can only be seen with a microscope.
Intrusive rocks cool slowly because
they never hit the surface. They have big crystals that can be seen without a
microscope, as shown in the below picture.

The geologic process that produces granite occurs gradually
over time. Granite is a solid and durable material due to the slow cooling
process from extreme heat.

Minerals That Give Granite Its Color

Quartz, feldspars, and micas are the most common minerals
found in granite. Quartz is normally the last mineral to crystallize, filling
in the gaps between the other minerals. The hardness, absence of chemical
reactivity, and near absence of cleavage of quartz contribute significantly to
granite’s desirable durable properties. The quartz appears gray, but it is
colorless, reflecting and combining the colors of the white and black minerals
around it.
    

Feldspars are usually white. Feldspars are the minerals that
give granite their color variations ranging from yellow to orange to pink or
blue. Dark feldspars may also give granite its black variations. Micas are
usually silver, black or brown, violet, or pink in color and provide the
sparkle is seen in some granites.

How they Extract Granite?

The low-cost blast extraction process involves drilling a
hole into the surface layer and blasting the area to remove granite blocks. To
loosen granite rocks, airbag extraction uses air instead of an explosion.
Stone-cut mining involves extracting granite from the earth with precision
equipment. The most expensive, but most effective, extraction method is
stone-cut extraction.

In India, some of the premier locations where granite quarries
manufacture colorful granite blocks in large quantities are Karnataka, Tamil
Nadu, Andhra Pradesh, Rajasthan, Orissa, Madhya Pradesh, and Telangana.

There are nearly 300 varieties of granite available on the
global market, with India supplying approximately 200 of them. Prime varieties
reflect a diverse range of colors, textures, and structures. These premium
varieties have a sizable resource base. Granite’s commercial names are derived
from its place, color, patterns, and so on.

Karnataka is known for producing granite in the colors Ruby
red, Chilly red, Cera grey, Kanakpura multicolor, Himalayan blue, and Sira
grey.

Andhra Pradesh is known for its Black Galaxy, Srikakulam
blue, and black granite varieties, while Tamil Nadu is known for its Jet-black
& Tipu-white, Kashmir-white, and Paradiso sea green granite varieties.
Orissa is known for its pink granite, silver-gray, seaweed green, chilka blue,
and grey wave granite varieties. 
                     

Block Selection

After Extraction, every block that
matches the size requirement is then thoroughly inspected to ensure that it meets
the quality requirements then the blocks are examined for cracks, veins, color
patterns


and other variations that help in ensuring the best blocks are
selected and further moved to process. Then the blocks are transported to
facilities where they will be cut down into slabs.

How are the granite blocks cut?

A continuous dripping of water over
the saw is needed when operating with machines to discharge heat produced by
the process and from this, it can be control temperature and won’t harm the
material.
After the block has been shaped with the saw, the adhesive is
applied to ensure that there are no cracks or breaks during the cutting
process.

 A flow of filtered water is also sprayed
during the cutting process to absorb any heat evaporating from the cutting
process and to eliminate any sparks.
These slabs are then carefully examined
for defects and moved for further processing.

Grinding and Polishing

Epoxy resin is used to fill all of the pits and
micro gaps that occur naturally, as well as to harden the stone even
further. This procedure ensures the granite ages well enough and lasts longer
while retaining its natural beauty. Before being processed, the surface of a
granite slab must be heated for the granite to absorb the resin more deeply.
The material must also be fully clean and dry for the resin to penetrate deep
into the surface’s smallest cracks.

Polishing will be the last move before the granite slabs are
finished. This step is performed to remove any excess solvent from the granite
surface and to smoothen the surface finish. Polish will be done according to the
requirement of the slab i.e High gloss, glossy, matt, natural, leather, flamed,
etc.
