Granite is a common type of intrusive, felsic, igneous rock which is granular and phaneritic in texture. Granite worktops are incredibly tough and hard wearing and bring a high end feel to any kitchen worktop. This rock consists mainly of quartz, mica, and feldspar. Occasionally some individual crystals (phenocrysts) are larger than the groundmass, in which case the texture is known as porphyritic.
Why Granite Worktops
Granite has long been a preferred material for kitchen worktops, thanks to its exceptionally hard-wearing, durable, and unique aesthetic qualities. Granite is easy to clean and maintain, provided some simple guidelines are followed. The granite used in making kitchen worktops is the same natural product as that found in classic building structures and monuments. Formed by the cooling of lava Millions of years ago, it is available in a range of beautiful, naturally occurring colours, from pink and grey, through to blue, brown and black. Although rough in its natural state, the surface of granite can be polished to a smooth, shiny finish. The use of Granite has increased over the centuries owing to the intrinsic strengths it has over other types of stone such as marble. Firstly, granite is highly resistant to weathering. Secondly, it is extremely heat resistant. Thirdly, it is very hard and durable, and does not scratch easily. These characteristics make Granite worktops the sublime choice. Although these characteristics mean granite is ideal for the cut and thrust of kitchen life, it is important to remember that it is a natural product and that certain basic steps should be taken in maintaining granite worktops thus ensuring they remain in top condition.
Granite Worktop Care
Firstly it is essential that a granite worktop is sealed to protect it from stains, and we carry this out in out factory in hastings East Sussex . A granite worktop, like any other worktop, should be cleaned regularly. The best way to clean granite worktops is with soap and water. Secondly, although granite is very unlikely to crack when exposed to high temperatures, it is still advisable to eliminate any possibility of marks and blemishes from hot pans and dishes by always placing a protective mat underneath hot items. Also, when using sharp or heavy objects it is better to err on the side of caution and use a chopping board rather than the worktop itself; although granite is tough, like any natural substance it can contain weak spots that may chip or crack. Finally, any spills should be cleaned up as soon as possible with soapy water, particularly acidic liquids such as wine and orange juice, acid easily stains granite worktops.
What is Granite
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, it 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 and 2.75 g/cm3, its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3-6 • 1019 Pa·s. Melting temperature is 1215 – 1260 °C. 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. It has been used as a construction material for thousands of years and this is not without good reason. It is extremely tough and durable making it suitable to a huge range of building projects from kitchen worktops and countertops to flooring and paths.
