Granite,
which is classified as an igneous rock,
is formed by volcanic action that liquefies
rock deep in the Earth and then solidifies
upon cooling. Granite has a crystalline,
granular structure consisting mostly of
quartz and feldspars, accompanied by one
or more dark minerals such as mica. The
range of colors of igneous rock will depend
mainly on the colors of the prevailing feldspars.
This formation contributes to granite's
strength, durability, and individuality-
the features that make granite the ideal
choice for a kitchen countertop. Granite
ranges from consistent grain structures
and colors, to multicolored stones with
veins or movement resulting from the varying
distribution of minerals.
Almost all granite that is used for countertops
is polished to a high-gloss finish. Certain
individual characteristics, such as pitting
fissures or dull spots are unique and inherent
in the geological blueprint of each slab.
The final appearance of the polished surface
of each type of granite is determined by
the specific composition or mix of feldspars,
quartz, and other minerals. While the overall
appearance will be that of a high-gloss
finish, some components within the granite
may not accept the same level of polish
as the rest of the crystals, which can result
in so-called dull spots or watermarks.
These spots may be visible on the darker
crystals found in some granite.
A characteristic referred to as pitting
(which is not often visible) may result
from grantie's crystalline structure, which
can sometimes result in small spaces that
form between the varying mineral crystals.
In some instances, certain small crystals
may also be removed during the polishing
process, causing the pits to become more
visible. Various steps will be taken during
the finishing process to reduce the visibility
of these pits, but they cannot be totally
avoided in all granite types. Pitting contributes
to the stone's unique personality, similar
to a beauty mark or freckle on a person.
This is part of the natural beauty of the
stone. Pitting will not become worse with
regular use or with the passage of time.
Fissures are a natural result of
the heating and cooling of the stone during
its formation millions of years ago. Fissures
will not grow or expand over time.
While the type and specific composition
determines the amount of pits, fissures
and dull spots, some granites exhibit these
characteristics more than others, and they
may also be more or less visible depending
on lighting conditions. Lighting plays an
important part in the overall appearance
of a finished granite countertop surface.
*IMPORTANT*
Pits, fissures and dull spots do not compromise
the integrity of the stone in any way; they
are natural characteristics of stone and
will not impair the function or durability
of the material. They are an expression
of nature and add to the timeless allure
of stone, setting it apart from man-made
surfaces.
