Granite, a holo-crystalline quartz-bearing plutonic rock, has - 10 to 50% of quartz as its component, the alkali feldspar/total feldspar in the ratio between 65 to 90%, and the modal concentration of other minerals is less than 10%. Cutting of granite follows the processing. The cutting of granite has been made easier by the use of steel abrasives. Use of such tools enhances cutting of granite, saves time and lends smoother edges. The granite is cut into thin slabs by multi-blade gangsaws, and using various types of granite cutting blades available in the market.
Granite is available in three main varieties of granite, which are as
Includes quartz, plagioclase, biotite and K-feldspar.
Also called Syenitic granite, contains hornblende as well as mica.
Composed mainly of Tourmaline, this variety of granite exhibits a wide
range of colors and is very rarely available as white or colorless
Of these three varieties, Biotite-granite is most prevalent and forms a
very suitable building stone for durability and decoration. These rocks,
by reason of their massive nature and homogeneous grain, are eminently
adapted for monumental and architectural work as well as for massive
masonries. Their wide range in appearance and colors white, pink,
red, grey, black, etc. renders the stones highly ornamental and
effective for a variety of decorative uses.
Based on the composition, the color and the make of the granite also
varies there are various types of granite comprising of over hundreds of
shades. Within India itself there are around 200 shades of granite
available. To name a few -Tropical Green Paradiso, Kerala White, Pink
