The marble, pleasant feeling of elegance

Marble is a metamorphic rock composed mainly of calcium carbonate (CaCO3). The word derives from the ancient greek marble (mármaron), with the meaning "shining stone", itself derived from the verb (marmaíro), which means "shine, shine." The marble is formed through a process of metamorphic sedimentary rocks such as limestone or dolomite, which causes a complete recrystallization of calcium carbonate which are predominantly composed and gives rise to a mosaic of crystals of calcite or dolomite (mineral) . The combined action of temperature and pressure during processing of the sedimentary rock marble, leads to the progressive obliteration of the original structures and textures in the rock, resulting in the destruction of any fossils, sedimentary layering, or other structure in the original rock. The color of marble depends on the presence of impurities' minerals (clay, silt, sand, iron oxides, nodules of flint), granules or existing within the original sedimentary rock layers. During the metamorphic process these impurities are moved and recrystallised from the pressure and heat. The outcome of the marbles are white limestone metamorfizzazione free of impurities. '

Marmo lastronato
For marble slab marble slab is defined as a "poor" completely plated (coated) plates (approximately 5 mm thick) of one or more marbles. The marble slab was used, such as plans for the furniture for high commissions. With this technique the masons of the past obtained marble tops on the use of saving precious marbles notoriously expensive. The low index of refraction of calcite that allows light to "penetrate" the surface of the stone before being reflected, gives this material (especially the white marble), a special light, which made it particularly popular for sculpture. The artist and sculptor Michelangelo preferred the "white marble" in Carrara for his works.

The marble from the quarries after extraction by means of hand "diamond", or by using the pressurized water technology, can be fabricated in the form of flat sheets. These range from a minimum thickness of 1 cm, up to a maximum thickness of about 30 cm: cm plates with a thickness less than would be too fragile, poorly resistant to bending stress and shear, while allowing the plate thicknesses greater than the phases of processing and transport of the material without cracking or breaking. A plate with a thickness of more than a foot is called "solid". The marble slabs are used as a finish, for example for covering floors and walls sometimes. Being a porous material tends to absorb oily substances, which is why it is sometimes subject to specific protective treatments.
 

Techniques for surface finishing

The main surfaces of marble processing techniques are:

Polishing - Polishing: Polishing of finished products and use the plate-polishing tape. These machines offer a bank deposit with a tape where the workpiece material, the belt runs over a bridge leads spindles, ie support of mobile equipment fitted with mechanical grinding and polishing, and keep holding the workpiece. In the marble processing machines generally use a number of spindles that varies between eight and twelve.


Flaming: along with the polishing process is the technique most commonly used surfaces. It is used for external paving because it offers both a nice decorative effect that a non-slip effect. This process provides a thermal shock, caused by a torch fueled by oxygen and propane, which forms the surface of the plate making it burst accentuate the natural color and giving it a certain roughness'.



Bush-hammering is a technique used to give an appearance of the plate surface and then sculpted not just smooth, smooth. The machines for this type of work using a piano rolls for the flow of material to be machined and fitted with a pneumatic hammer to its ends' of hard material tools that are designed to sculpt the surface.



Rifling: consists of a series of furrows in the area concerned.


Sandblasting: provides a smoothing of the plate using a jet of water mixed with sand carried by a nozzle with adjustable speed flowing to the workpiece, in this case lies on a roller.


Brushing, antiquing is a technique that serves to give the worn surface of the plate appearance (this is also called antiquing). The processing is carried out via the use of abrasive brushes applied to machines for sanding. The brush should have a greater impact to the concentrations where the material has the most tender and then you get an uneven surface but lucid. This technique is gradually becoming more widespread and can enhance the effect by roughening of the previous material.
