Marble
A marble is a metamorphic rock formed by
alteration of limestone or dolomite, often irregularly colored by
impurities and used especially in architecture and sculpture. Marble
tiles are suitable for bathrooms, entryways and fireplaces, living &
dining areas. Marble floor tiles are also used for both interior and
exterior flooring applications. Some of the different colors of
marble are white, red, black, mottled and banded, gray, pink, and
green. 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. Marbles are formed
from limestone or dolomite that has undergone enough heat and
pressure to get metamorphosized into a crystalline structure. This
metamorphosis 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. It has an
interlocking or mosaic texture composed of crystalline grain of
calcite, dolomite or both. Texture of marble depends on the form,
size and uniformity of grains. The chemical constituents of marble
determine the color of the marble. 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 bands, streaks and clouds. Black and grayish shades
are due to graphite; pinks, reds are mainly due to the presence of
manganese oxides or hematite. The Taj Mahal in India is
the best illustration of marble architecture.
