What the different between granite & solid surface?
lazy to type so i google for u .......
Granite (play /ˈɡrænɪt/) is a common and widely occurring type of intrusive, felsic, igneous rock. Granites usually have a medium- to coarse-grained texture. Occasionally some individual crystals (phenocrysts) are larger than the groundmass, in which case the texture is known as porphyritic. A granitic rock with a porphyritic texture is sometimes known as a porphyry. Granites can be pink to gray in color, depending on their chemistry and mineralogy. By definition, granite is an igneous rock with at least 20% quartz by volume. Granite differs from granodiorite in that at least 35% of the feldspar in granite is alkali feldspar as opposed to plagioclase; it is the alkali feldspar that gives many granites a distinctive pink color. Outcrops of granite tend to form tors and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite is usually found in the continental plates of the Earth's crust.
Granite is nearly always massive (lacking internal structures), hard and tough, and therefore it has gained widespread use as a construction stone. The average density of granite is between 2.65[1] and 2.75 g/cm3, its compressive strength usually lies above 200 MPa, and its viscosity at standard temperature and pressure is 3-6 • 1019 Pa·s.[2]
The word granite comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a crystalline rock.
Granitoid is a general, descriptive field term for light-colored, coarse-grained igneous rocks. Petrographic examination is required for identification of specific types of granitoids.[3]
Solid Surface is a man-made material usually composed of bauxite, acrylic or polyester resins and pigments. It is most frequently used for seamless countertop installations, such as with cultured marble.
Solid surface is a non-porous low-maintenance countertop surface. It can mimic the appearance of stone, wood and other naturally occurring materials, and can be joined invisibly by a trained craftsman. Typically manufactured in sheet form for fabrication into finished countertops, solid surface can also be cast into a variety of shapes, including sinks, shower pans and bathtubs. Sheet goods can also be heated and bent into three-dimensional shapes using a process called thermoforming, which adds to the versatility of the product.
In a residential setting, solid surface can be used as kitchen countertops, bathroom vanity tops, and shower and tub surrounds. Countertop fabricators typically join solid surface sheets into desired shapes using a two-part adhesive, after which the cured joint is machined flat. The same method is used to create extra thick edges, which can be machined using tools and techniques similar to those used to work hardwoods.
A major appeal of solid surface is its seamless nature. Solid surface sinks, such as with cultured marble, can be joined to the countertop surface with no gaps, which eliminates areas for water to collect and bacteria to grow. Integral backsplashes can also be created that follow the contours of the wall “seamlessly” and without gaps.
Should the material become scratched or broken, solid surface can, in most cases, be repaired quickly by a trained fabricator. Because the surface is solid throughout, a countertop that has undergone years of wear and tear can be refinished. The installed product is available in a variety of finishes, ranging from matte to high-gloss, although most manufacturers recommend a matte or satin finish for ease of maintenance.
