Hard Rock, an Easy Choice

 

It would be an error to say that granite is a natural stone whose time has come since it never actually left. New man made products just became poplar at that time. But experts now say it is on its way back on mass.

Granite was previously known thousands of years ago, and there are surviving granite buildings dating back to very old times. The Great Pyramid of Giza, for example, houses a sarcophagus of red granite. The capstone from the Black Pyramid is on display at the Egyptian Museum in Cairo. One can still see the illumination crimson granite surfaces of the Red Pyramid the third major of the Egyptian pyramids. Granite was also used on a smaller scale by early civilizations for columns, walls, floors, door lintels and windowsills.

Nowadays, granite is everywhere on the many structures in vast proportions, such as our present skyscrapers, due to its strength and resistance to fading. Nevertheless you do not have to own a skyscraper to take pleasure in its benefits. New techniques in quarrying and fabrication have prepared this natural stone for more extensively available and more beautiful than ever to homeowners. With colours in abundance and new types being found on a frequent basis, granite will always be with us.

One of the most hardwearing natural stones on Earth, super seeded only by diamond, granite is a crystalline, igneous rock. It is one of the different volcanic rocks that cools and solidifies slowly from magma deep underground. Granite is the most universal intrusive rock so named because the magma from which it forms often intrudes into the neighbouring rocks uncovered at the Earth’s surface. Made up  primarily of feldspar, quartz and lesser amounts of mica, granite may also comprise other minerals in much smaller amounts, such as magnetite, pyrite, garnet and hematite.

The varying fractions and patterns in which the minerals take place create the arrangement of granite varieties we see.

As feldspar is usually the major part of granite, it also most very much influences the colour. white, pinks, greens, reds and greys have been used, but other colours are now more frequent.

You can find almost every colour, now, like cobalt blue, purples, gold, rusts, all shades of green, blacks, greys, silvers and iridescent blue Labrador.

Granites are classified in a variety of ways, one way being by grain the word granite, in fact, comes from the Latin word granum, which means grain fine, medium or coarse. The size of the feldspar crystals decides the grain classification; the crystal size is usually related to the rate of cooling, so the coarse-grained types took the longest time to cool.

Not all granites are equal. The hardness of the granite is worked out by its concentration.

The rigidity of granite is determined by its feldspar and quartz amounts. Granite with more quartz is more permeable and less hard than darker varieties.

As contrasting to crushed stones, granite is known as an element stone, which means it is a natural structure stone that has been cut and finished to certain stipulation.

Because granite forms a large part of the Earth’s crust, it is abundant. It is taken from the earth in large blocks weighing anywhere from 8 to 23 tons.

Granite is quite widespread throughout the planet, but the areas with the most commercial granite quarries are Scandinavia, Spain, Brazil, India, and several African countries, as well as Angola, Namibia, South Africa and Zimbabwe. Some also comes from China, Italy, Madagascar, North America, and Russia.

The quarrying procedure used to involve drilling, pounding, blasting and sawing. But that has been simplified and updated with the arrival of the diamond wire saw a group of wires covered in diamond that allow pulling whole blocks of granite from the earth in a faster, less vicious way.

Granite is cut from the mountains in huge blocks (about 7 by 10 by 20 feet), then transported by articulated vehicle to a mill, The blocks are then put below a gang saw wet sawing machine of 70 odd blades across  and cut into slabs 20 to 30 millimetres thick like bread at your local super market. Not like a loaf of bread, it takes around 24 hours to slice through a whole block. Then each slice is polished by machine. The slabs are then put into groups of ten. Exporting in this way gives the best colour regularity to the wholesaler.

Due to the rising customer need, suppliers of granite are always looking for and taking on large investments in finding new quarries, they are continually looking for new colours, and the searching for new colours is down to the customer’s requirements.

The challenge for quarries at the moment is not the finding the new quarries or working out how deep the granite is, but somewhat working out if the opening of a new quarry is significance to the investment. There is at present no way to work out what colours a quarry will uncover and there can be changes in a colour within the same quarry. If the colour changes, sometimes they just might change the granites name.

About 80 percent of home trades men are now using granite. In the understanding that it adds value to a home, particularly when used in the kitchen.”

The most common use of granite is on for kitchen worktops, Granite used on a countertop will last longer than the units its on.

Granite is also being installed on floors, predominantly in modern homes and in commercial places. New techniques are being used to make granite anti slip: Flaming to create a more crystallized surface, brushing to add undulations, and sandblasting and honing to dull the surface are all ways to make it a safer material to use on a floor.

Granite is also finding its place in new bathrooms and en suites bathrooms, and is also a good option for out side. Its knack to endure the elements makes it appropriate for cladding, paving stones and curb stones.

Granite is also used in many barbecues because it is hard wearing. And in addition to being attractive, it’s also well liked, as it’s flat and easy to work on.

Granite is naturally bacteria-, heat-, scratch-, and stain-resistant. But, if you’re worried about staining, a builder can add a surface sealant to increase stain-resistance and can help you select one that is nontoxic, which is, of course, imperative in food preparation zones.

Granite has it all. Resilience, adaptability and sheer attractiveness and technological advances in quarrying, fabricating and fitting make it a good alternative for inside or outside.
