Marble Stone Texture Specifications + Purchase Price
as a general information, one of the most interesting facts about Marble stone with granular texture like limestone or dolomite (i.e. a rock composed of calcium-magnesium carbonate) is that it has been restored under the influence of heat, pressure and aqueous solution.
marble stone texture high resolution
Commercially, it contains all decorative calcium-rich stones that can be polished, as well as some serpentines (word antiquities).
Petrographically, marble is massive rather than thin layered and consists of a mosaic of calcite grains that rarely show any trace of crystalline form under the microscope. They are crossed by microcracks corresponding to rhombohedral cleavages of calcite. In the more deformed rocks the grains show grooves and are elongated or crushed in certain directions.
Marble is often interbodied with metamorphic rocks such as mica schists, phyllites, gneisses, and granulites, and occurs most frequently in older layers of the earth's crust deeply embedded in regions of high folding and igneous intrusion.
Occasionally, as in Carrara, Italy, and Bergen, Norway, rock restoration has not completely destroyed the organic structures.
Most of the white and gray marbles from Alabama, Georgia, western New England, Yule, and Colorado are reclaimed stones, as are a number of famous Greek and Italian statuary marbles from antiquity still excavated Among these.
Parian marble, Pantelic marble from Attica in which Phidias , Praxiteles and other Greek sculptures made their major works, and the snow-white Carrara marble used by Michelangelo and Antonio.
Canova and favored by modern sculptors The National Gallery of Art in Washington has an exterior of Tennessee marble , and the Lincoln Memorial has marble from Yule, Colorado, Alabama (roof transparencies), and Georgia (Lincoln statue).
Even the purest metamorphic marbles, such as Carrara, contain some accessory minerals, which in many cases make up a considerable part of the mass Quartz is most common in small spherical grains, colorless or pale yellow mica (muscovite and phlogopite), dark lustrous fragments of graphite, iron oxide and small crystals of pyrite
Many marbles are other minerals, usually silicates of lime or magnesia. Diopside is often visible and can be white or light green; White banded tremolite and light-green actinolite also occur; The feldspars encountered may be potassium but are often plagioclase (sodium-rich calcium) such as albite, labradorite.
anorite or scapolite, various types of garnet, vesuvianite, spinel, forsterite, perichlase, brucite, talc, zoisite, wollastonite, chlorite , tourmaline, epidote, chondrodite, biotite, titanite and apatite are all potential accessory minerals. Pyrrhotite, sphalerite, and chalcopyrite may occur in small amounts.
These minerals represent impurities in the original limestone, which react during metamorphism to form new compounds. Alumina represents a mixture of clays; The silicates get their silica from quartz and clays; The original sedimentary rock contains iron from limonite, hematite or pyrite. In some cases it is possible to trace the original beds of calcareous sediments by mineral bands in the marble.
Silicate minerals, if present in any significant quantity, can color marble; For example, green in the case of green pyroxene and amphibole; brown in garnet and vesuvianite; and yellow in epidote, chondrodite and titanite. The black and gray colors result from the presence of fine scales of graphite.
Flakes of calcium-silicate rock alternate or form nodules and bands with flakes of marble, sometimes producing interesting decorative effects, but these rocks are particularly difficult to finish because of the large difference in hardness between silicate and carbonate minerals.
Subsequent physical deformation and chemical decomposition of metamorphic marbles often produce attractive colors and varieties.
Decomposition gives hematite, brown limonite, pale-green talc, and especially, ophichalcite or ward characterize the antiquities, the derivatives of forsterite and diopside become green.
or yellow snakes Earth movements can fracture rocks, producing fissures that are later filled with calcite veins; Thus a beautifully bricked or veined marble is formed. Sometimes broken pieces are bent into spheres by the marble flow under pressure.
The so-called onyx marble consists of concentrated zones of calcite or aragonite that were deposited by cold-water solution in cavities and fissures and around spring outlets.
They are, strictly speaking, neither marble nor onyx, because true onyx is mostly banded chalcedony made of silicon dioxide. Onyx marble was anciently "alabaster," but alabaster is now defined as gypsum, a calcium sulphate rock.
These marbles are usually brown or yellow in color due to the presence of iron oxide. Well-known examples include Italian antiquities giallo antico ("ancient yellow marble"), red-spotted Siena marble from Tuscany, large Mexican deposits at Tecali near Mexico City and at El Marmol, Calif., and Algerian onyx marble used in buildings in Carthage and Rome, 1849 Oud-Abdallah -and rediscovered near the city.
Unaltered limestones or fossil remains showing interesting color contrasts are frequently used for architectural purposes.
For example, the fossil coral-rich "Medrepore Marble" and "Encrinital Marble" in the Paleozoic rocks of Great Britain (251 million to 542 million years old) contain crinoid stems and arm plates with characteristic.
circular cross sections or are clusters of freshwater snail shells embedded in green limestone they were a favorite material of medieval architects and can be found in Westminster Abbey and many English cathedrals.
Black limestones with bituminous matter, which generally emit a putrid odor when struck, are much used; The well-known Belgian Petite Granite is black marble with crinoid stem plate, derived from a fossilized echinoderm (an invertebrate marine animal).
Marble stone with high resolution in its texture is mainly used for buildings and monuments, interior decoration, statues, table tops and novelties. Color and form are their most important attributes.
Abrasion resistance, which is a function of the cohesion of the grain and the hardness of the constituent minerals, is important for floors and stair treads Light transmittance is important for statuesque marble, varying its luster from about 12.7 to 38 mm.
Brachiated, colored marble, onyx marble and the term antiquity is mainly used for interior decoration and novelty. Statue marble, a precious variety, should be pure white and of uniform grain size.
To be durable for exterior use, marble must be uniform and porous to prevent the ingress of water that can warp the stone or cause disintegration or freezing and also be free of pyrite and other impurities that can stain or weather.
Exposed to atmospheric moisture, calcite marble has a relatively smooth surface during weathering and is acidified by gases such as carbon dioxide and sulfur dioxide but dolomite limestone can weather with an irregular, sandy surface from which dolomite crystals emerge.
The main mineral in marble is calcite, and varying the hardness, light transmission, and other properties of this mineral in different directions has many practical consequences in making some marbles Calcite crystals are doubly refractive - they transmit light in both directions and more light in one direction; Therefore, slabs prepared for applications in which transparency is critical are cut parallel to that direction.
The bending of the marble slabs is attributed to the directional thermal expansion of the calcite crystal on heating.
MiningThe use of explosives in marble mining is limited by the danger of fracturing the rock. Instead, channeling devices that use chisel-edged steel rods are about 5 cm in diameter.
Wherever possible, advantage is taken of natural joints already existing in the rock, and parallel expansion of platy-fibred minerals results in cuts being made in the direction of easiest cleavage Marble fragments marked by joints and cuts are separated by driving wedges in drill holes.
Mill sawing on the tracks is done by a set of parallel iron blades that move back and forth and are fed by sand and water.
Marble can be machined with lathes and carborundum wheels and then polished with increasingly fine grades of abrasives. at least half of the total marble production even with the most careful mining and manufacturing techniques. e is garbage.
Loved by emperors and craftsmen alike, marble has been one of the most beautiful and sought-after stones for centuries.
Whether pure snow white or studded with dramatic, colorful veins, each piece of marble is a unique and stunning work of art, adding an undeniable touch of luxury and opulence when used in the home. But what exactly is marble? Let's find out how this stone was created and why it has been popular for so long.
Marble is a metamorphic rock, which is a rock that has been physically and chemically transformed over time due to intense heat and pressure.
Marble begins life as limestone, a soft stone composed primarily of calcite. Under the heat and pressure caused by magma or plate tectonics, this limestone begins to redefine, changing the structure of the rock and the calcite crystals grow and fuse together.
From Macedonia to Vermont, marble can be found in many areas of the world, but the most famous varieties come from Italy and Greece, where its color is often pure.
Clarity, of course, refers to the lack of color variation in a particular stone sample. Although colored veining is a highly desirable feature for many, the purest marbles are almost completely white or very light.
Veining is caused by mineral deposits that are either in the original limestone or are present when the limestone is transformed into marble.
Minerals tend to settle in layers, which we call "weining". Depending on the amount of minerals in the stone, veining can be very minimal – thin, fine lines – or dramatic – broad bands of color that look almost like smoke inside the marble.
Minerals present during restoration can sometimes stain the entire piece of marble in different colors. The most common are blue, gray, pink and red, but green, purple and yellow marbles can also be found. Clay, mica, quartz, iron oxide are some of the most common minerals found in marble and cause the red, gray and white color or veining.
Hematite and iron oxide are also often present and can produce reds, pinks and browns, while limonite causes yellows and serpentine causes deep, rich greens.
Regardless of the color, one of the most unique aspects of marble is that it is translucent, meaning you can see the surface outside.
Although no marble is completely transparent you can often see at least a few millimeters of the stone, which is one of the reasons why it is so widely used in sculpture. The translucency of the stone gives it more depth, making human sculptures appear fuller and more alive than those made from more opaque materials.
Marble is the perfect softness for carving, although its sensitivity can be detrimental in many cases. Although many marble buildings and statues have stood for thousands of years, differences in weather and temperature can cause them to crack and disintegrate like acid.
That being said, mining still needs a lot of work. Marble deposits can often be huge and require explosives to break up the rock. The machines then help create grooves in the stone that are leveraged to separate from the rock face.
Marble is still widely used in buildings today and can be seen in churches, town halls and historic buildings. However, it can also be found in a modest household. Marble countertops are loved by homeowners for their beauty and especially by those who like to cook.
Because the surface is always cool, it prevents the butter dough from softening too much and helps the chocolate to get the perfect consistency for making truffles, candies and other treats. Although marble countertops require frequent sealing and care to prevent stains and acid erosion, the beauty the stone adds to your kitchen is well worth the effort.
Of course, you can use marble elsewhere in your home. Marble tiles can look amazing in an entryway and can also be used to create a decorative backdrop in a kitchen or bathroom. A marble fireplace, whether plain or carved, can also add drama and elegance to your living room.
One look at a piece of marble and it's easy to see why it's been a favorite for generations. Its smooth, cool surface, elegant veining and unique color flavor create something that is organically beautiful. Fortunately, these things aren't just for kings anymore.
Whether you want the dramatic look of a small carved fireplace in your kitchen, marble is an affordable luxury that can be tailored to your needs.
