Marble , a term from the Latin word marmor , is a metamorphic rock that develops from crystallized limestone . Calcium carbonate is its main component.
When limestone is under high pressure and high temperature, it crystallizes. Thus, a process of metamorphosis begins to develop that, with the intrusion of other elements, gives color and modifies the composition of the marble, which is characterized by its compact texture and the shine it achieves from polishing.
Typically, marble is combined with other substances to create lines or specks or give it different shades. Thus, thanks to its aesthetic qualities, the material is used in the field of decoration, construction and even art .
Marble sculptures are made by carving the rock. Among the works that are developed in this way appear statues, fountains and tombs .
According to specialists, the translucent surface of the rock allows the human figures made of marble to appear realistic thanks to the visual depth achieved. Another advantage that marble offers over other materials is its resistance .
Among the most valued marbles in the world is Carrara marble . It is obtained from quarries located in the Apuan Alps , in the area of the Italian municipality of Carrara .
Working marble is an art that requires a series of complementary knowledge, including techniques and tools, to achieve the best possible results. The first step is cutting the marble . Before proceeding we must take into account that each type has different degrees of resistance, hardness and crystallization, which is why the process varies depending on the case.
It is possible to cut it dry or wet ; In both cases, it is necessary to proceed with great patience to avoid damaging the surface. The discs used for cutting should be reserved exclusively for the treatment of marble, since if used with other materials they lose their uniformity and generate unsatisfactory results.
Regarding the tools available on the market for cutting marble, we have the radial and the grinder , with electroplated discs, although you can also use a tabletop machine with hydraulic cooling and wet cutting discs.
Once the cut has been carried out, it is time to sculpt the marble, a task that requires a combination of skill and hand strength. Unlike the previous step, artistic vision plays an important role in this one. It is similar in the security that we must have in the manipulation of material and tools, because errors are very difficult to correct.
Despite the technological advances that abound in other areas, today it is still common to sculpt marble by hand, even dispensing with certain tools that offer very convenient features, among which are pneumatic hammers (with hammers, gratines or chisels) and compasses .
Another treatment that is usually applied to marble is drilling , for which a widia drill bit or a diamond drill bit can be used, for small or large diameters, respectively. Precisely, before making a hole in a piece of marble we must accurately define the diameter; Next, we use the smallest drill bit and finally, the largest.
José Mármol , meanwhile, was an Argentine writer, politician and journalist born in 1817 and died in 1871 . In the Buenos Aires district of Almirante Brown , a town is named after him.
