GRANITE
Granite is an important structural and decorative stone. It’s
used for immense structural work due to its high compressive strength and
durability. It is the hardest structural stone. Granite’s rich colors, stiffness
and density, make it an ideal choice for flooring, counter tops, vanities as
well as exterior applications. Many stylish patterns and colors make granite the
most versatile and trendy of all stones. It is also a very low-maintenance
stone. Granite is composed of quartz, feldspars, micas and other minerals. These
minerals contribute to the color and texture of the granite stones. Granites get
their wonderful variety of colors and patterns from minerals that are melted
into the liquid mass as it is formed..
MARBLE
Marble has been valued for thousands of years for its rich
palette of beautiful colors and appearance and is perfect, pretty much anywhere
in the house. Marble stones consist of limestone that has undergone heat and
pressure. A transformation process takes place when the weight of overlying
material, pressure from crystal collisions and heat from the earth's core
generate temperatures in excess of 1800ºF.Texture of marble depends on the form,
size and uniformity of grains. The element components of marble determine the
color of the stone. Generally calcite and dolomite marbles are of pure white
color. Variations of whiteness of pure marbles are due to the mixture of foreign
substances. Such impurities form streaks and clouds.
TRAVERTINE
Travertine is generally used for floors, walls, countertops
and for outside as cladding and pavement. Travertine is generally filled with
grout before it is honed or polished, which produces a uniform surface more like
other marbles. Unfilled travertine is also quite beautiful, and is often seen as
exterior surfaces of buildings. Travertine stones result from hot spring water
penetrating up through underground limestone. When the water evaporates, it
leaves behind layers of dissolved limestone and other minerals, giving it its
banded appearance. Travertine stones are generally light-colored beiges and
tans.
LIMESTONE
The soft limestone stones are ideal for today's more casual
and comfortable environments. Generally these soft beiges and tans are suitable
for bathrooms, fireplaces, counters and floors. Limestone is a sedimentary rock
that is formed at the bottom of lakes and seas, as organic matters settle to the
bottom. As more and more layers build up over thousands and millions of years,
adding more and more weight, the heat and pressure cause chemical reactions to
take place to harden the sediments into solid stone
SLATE
The lively colors and unique texture make slates appropriate
for interior as well as exterior applications. Slate is formed of compressed
layers of sediments formed under ocean. Since it is formed in layers, it can
easily be split to expose beautifully textured surfaces. The usual colors of
slates are earthy browns, beiges, yellows, black, dark-grays, and greenish-gray,
pinks, purples and copper are also found. They usually exhibit lot of variations
even in the same quarry. Slates are used for flooring, cladding and landscaping.
SANDSTONE
Sandstone consists of sand covered by silica, iron and lime.
Cementing material determines the color of sandstone, iron sandstones are
reddish, brownish; carbonaceous, black; siliceous, white and argillaceous,
earthy to buff. The hardness of sandstones is important in deciding suitability
for applications for sandstone.
QUARTZITE
Quartzite stones are the same with slates, but with higher
content of quartz in them, which gives them, a bright texture. They are very
similar to slates. Like slates, quartzites are used for various applications
depending on their hardness.
