MARBLE

Marble is a metamorphic rock that is created as a result of the metamorphosis of a combination of rocks under intense pressure and temperatures. These rocks include calcite, limestone, dolomite and serpentine. The main component of marble is calcium carbonate and contains acidic oxide. Marble takes hundreds of years to form and is found among the oldest parts of the Earth’s crust.

One of the top reasons homeowners select marble for their countertops and floors is the elegant beauty it imparts to the home. It can spruce up the dullest looking bathroom, kitchen, or walkway with its wide variety of colored marble patterns. With the right care, marble has good longevity and can be used in different parts of the home to add sophisticated and classy looks.

There are advantages to having marble countertops in the kitchen, especially for home bakers and personal chefs. The surface of marble stays cool, making it an ideal roll-out surface for pastries and doughs. Many people are not aware that marble is also heat resistant. It will not catch fire or burn, and you may place semi-hot pans on it for relatively short periods of time without damage to the surface.

Marble is a natural stone  which is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions. In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.Marble is commonly used for sculpture and as a building material.

Marble has many variation due to has variety of its minerals in it. Even the purest of the metamorphic marbles, such as that from Carrara, contain some accessory minerals, which, in many cases, form a considerable proportion of the mass. The commonest are quartz in small rounded grains, scales of colourless or pale-yellow mica (muscovite and phlogopite), dark shining flakes of graphite, iron oxides, and small crystals of pyrite.

When marble is installed and properly sealed and maintained, it has the potential to last for a lifetime. So it is less resistant to scratching, staining, and cracking than other countertop surfaces. It is also softer than surfaces like granite, this makes it easier to produce a wide variety of edge profiles to make distinguished looking cuts and arches. These types of designs come at a higher cost, but in comparison to granite are still much lower.

Just like many other types of natural-stone countertops, marble needs to be sealed often to preserve its beauty and quality.

Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.

The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the calcite during metamorphism. While marble can appear superficially similar to quartzite, a piece of marble will be able to be scratched by a metal blade, and marble will fizz on contact with dilute hydrochloric acid.

Marble is a metamorphic rock made out of limestone or dolomite: When  limestone or dolomite is subjected to tremendous pressure and heat for a long time, it gets squashed into marble. Marble is found in the mountainous regions. Turkey is one of the most rich and popular source of marble and limestone with holding %40 percent of world natural stone reserves and with the highest variety of colors.

Limestone is a sedimentary rock composed of calcium carbonate, plus calcium and/or magnesium. It is formed when layers of minerals (particularly calcite), fine sediment, and the skeletons and shells of marine organisms undergo lithification. Terrestrially-formed limestone is known as travertine.

Colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert. These minarels lead marble to be white, beige, bluish, gray, pink, or black.

Marbles are used principally for buildings and monuments, interior decoration, statuary, table tops, and novelties. Colour and appearance are their most important qualities. Resistance to abrasion, which is a function of cohesion between grains as well as the hardness of the component minerals, is important for floor and stair treads. The ability to transmit light is important for statuary marble, which achieves its lustre from light penetrating from about 12.7 to 38 mm (0.5 to 1.5 inches) from where it is reflected at the surfaces of deeper lying crystals.

Brecciated, coloured marbles, onyx marble, and verd antique are used principally for interior decoration and for novelties. Statuary marble, the most valuable variety, must be pure white and of uniform grain size. For endurance in exterior use, marble should be uniform and nonporous to prevent the entrance of water that might discolour the stone or cause disintegration by freezing. It also should be free from impurities such as pyrite that might lead to staining or weathering.

Calcite marbles that are exposed to atmospheric moisture made acid by its contained carbon dioxide, sulfur dioxide, and other gases maintain a relatively smooth surface during weathering; but dolomite limestone may weather with an irregular, sandy surface from which the dolomite crystals stand out.

The use of explosives in the quarrying of marble is limited because of the danger of shattering the rock. Instead, channeling machines that utilize chisel-edged steel bars make cuts about 5 cm wide and a few metres deep.

Wherever possible, advantage is taken of natural joints already present in the rock, and cuts are made in the direction of easiest splitting, which is a consequence of the parallel elongation of platy or fibrous minerals. The marble blocks outlined by joints and cuts are separated by driving wedges into drill holes. Mill sawing into slabs is done with sets of parallel iron blades that move back and forth and are fed by sand and water.

The marble may be machined with lathes and carborundum wheels and is then polished with increasingly finer grades of abrasive. Even with the most careful quarrying and manufacturing methods, at least half of the total output of marble is waste. Some of this material is made into chips for terrazzo flooring and stucco wall finish. In various localities it is put to most of the major uses for which high-calcium limestone is suitable.

Our stone blocks, which we supply from Afyon White Marble, Silver Travertine, White Travertine, Marmara White Marble, Burdur Beige, Red Travertine, Classic & Noce Travertine, Breccia & Bardiglio quarries, can be sized in desired sizes and according to the projects.
