Granite is an a type of real rock called igneous rock, which means it was once molten and it formed as it cooled
deep within the earth. Different minerals within granite typically appear as small specks and flecks throughout
the stone, creating the salt and pepper look. Other types of granite may have veining
similar to marble. Granite is extremely hard and durable, and is practically scratchproof. It can be
highly polished and shiny or finished in a variety of other ways. Granite countertops are easily
cleaned because of its low porosity. Granite is available in a wide range of colors.

Granite Physical Properties
In terms of its physical properties granite is a unique material. These properties lending uniqueness to granite are:
Porosity/permeability
Granite has almost negligible porosity ranging between 0.2 to 4%.

Thermal Stability
Granite is highly stable thermally, therefore shows no changes with the change in temperature. Granite is impervious to
weathering from temperature and even from the air borne chemicals. It is the high resistance to chemical erosion that
makes granite useful for making tanks to store highly caustic material.
Co-efficient of expansion
The co-efficient of expansion for granite varies from 4.7x10-6 – 9.0x10-6(inch x inch).
Variegation
Granite shows consistency in color and texture.Hardness
It is the hardest building stone and hardness of granite that lends it excellent wear.

Granite Cleaning
Though granite is a hard and non porous stone that is unaffected by most chemicals it still requires high degrees of
care while cleaning. While cleaning, the use of harsh chemicals should be avoided. Here are few recommendations to
keep granite surface clean: Regularly dust the surface.
Use few drops of neutral cleaner, stone soap, or a mild liquid dish washing detergent or warm water.
Too much cleaner or soap may leave a film and cause streaks.
Use a clean rag.
the products containing acids should be avoided. The acid in high concentration etches the surface.
After using the soap solution, the surface should be rinsed properly.
Do not mix bleach and ammonia; this combination creates a toxic and lethal gas.
Do not use powders or creams that may create scratches.
In the kitchen extremely hot pans should not be kept over granite slabs since it quickly absorbs heat and distributes it
out.

Granite Composition
Granite, the hard natural igneous rock having visible crystalline texture is formed essentially of quartz and orthoclase or
microcline. The principal constituents of granite are feldspar, quartz and Biotite. However the percentage composition of
each varies and accordingly impart different color and texture to the final product. The percentage composition of
feldspar varies between 65-90% , of quartz can extend from 10 to 60% and that of biotite lies between 10 to 15%.
