We have an article about " the uses of marble " that includes photos and descriptions of marble in many types of uses. Gray Marble: This specimen has calcite cleavage faces up to several millimeters in size that are reflecting light. The specimen is about two inches five centimeters across.
Calcium carbonate medicines: Marble is composed of calcium carbonate. That makes it very effective at neutralizing acids. Highest purity marble is often crushed to a powder, processed to remove impurities, and then used to make products such as Tums and Alka-Seltzer that are used for the treatment of acid indigestion. Crushed marble is also used to reduce the acid content of soils, the acid levels of streams, and as an acid-neutralizing material in the chemical industry.
The best way to learn about rocks is to have specimens available for testing and examination. Color: Marble is usually a light-colored rock. When it is formed from a limestone with very few impurities, it will be white in color.
Marble that contains impurities such as clay minerals, iron oxides, or bituminous material can be bluish, gray, pink, yellow, or black in color. Marble of extremely high purity with a bright white color is very useful. It is often mined, crushed to a powder, and then processed to remove as many impurities as possible. The resulting product is called "whiting.
Acid Reaction: Being composed of calcium carbonate, marble will react in contact with many acids, neutralizing the acid. It is one of the most effective acid neutralization materials. Marble is often crushed and used for acid neutralization in streams, lakes, and soils.
It is used for acid neutralization in the chemical industry as well. Pharmaceutical antacid medicines such as "Tums" contain calcium carbonate, which is sometimes made from powdered marble. These medicines are helpful to people who suffer from acid reflux or acid indigestion. Therefore, it is essential to ascertain the exact kind of pollutants that cause marble deterioration.
The forces of nature may produce a decaying effect on the look and structural reliability of marble. These agents include temperature, snow, rain, wind and atmospheric pollutants. Weathering agents normally act in combination with the other agents to increase the deterioration of marble. Rainwater, particularly in combination with the atmospheric gases, may cause the dissolution of the marble, generating salt movement within the microstructure.
Temperature can intensify the deterioration rate and the patterns of salt relocation within the stone. High temperatures normally multiply the chemical changes. Sudden changes in temperature can cause stresses due to the differential in expansion. Moisture is considered to be one of the foremost causes of the problems that may happen.
However, other troubles like erosion due to wind and mutilation may also occur. Marble has numerous applications for structural and decorative purposes. It is utilised for outdoor sculpture, external walls, floor covering, decoration, stairs, and pavements. The technique of stone usage can influence exposure severity.
Marble is considered the stone for the emperors and gods. The majority of prehistoric monuments were made of marble. Marble has decorated the corridors of cathedrals and historical places. Marble tiles cover the floors of the affluent and also beautifies the baths of more moderate homeowners. These tiles are either polished or honed. Polished tiles provide a stylish appearance, though they are extremely slippery when wet.
Honed tiles offer more grip and are considered safe. Use of several treatments can slow the marble deterioration process. Marble is vulnerable to etching and staining by water and chemicals, for which appropriate advanced sealants have been developed to reduce this risk considerably.
Marble deposits can be found in various countries around the globe. The United States of America is also a high-level Marble producer, with states such as Alabama and Texas having especially large deposits to be found within their borders. Marble takes place in massive deposits that may be hundreds of toes thick and geographically good sized.
This permits it to be economically mined on a large scale, with a few mines and quarries generating tens of millions of lots in keeping with yr. Most of these rocks are made into either crushed stone or dimension stone. Crushed stone is used as an aggregate in highways, railroad beds, constructing foundations, and different kinds of construction. Dimension stone is produced by sawing marble into portions of particular dimensions.
These marbles are considered to have colorful cloud fins swirling in, vivid veins, the freshest color of any natural stone. Each color represents its own characteristic. Hoang Gia gives you an overview of them so you could choose your suitable marble for your design, help create a home expressing your own style and raise your inspiration.
Black: Mystery, luxury and power are what black brings. Black has the effect of making the space more luxurious, bringing beauty full of charm, engaging and stimulating curiosity. Using of black marble would give your space a special attraction, a mysterious and authoritative style.
Yellow: means joy and excitement. The color of sunlight radiates feelings of warmth, enjoyment, and mental activity. Yellow marble brings a different beauty thanks to its uniqueness and the meaning of East. The architectural feeling is being plated with luxurious gold. If combined with light, the space will be more cozy and classic. Red: symbolizes fire, associated with power, dedication, courage and sacrifice. Besides, red is also the color of luck, emotions and love, giving people confidence in work and life.
Red space design helps increase mental and emotional excitement, connection and increase love for family members. Marbles colored by this process in the rough, afterward take a most beautiful polish, and specimens of dolomite polished previous to coloring have their polish hightened by it. An effort has been made in this process to imitate the means by which the valuable colored building stones naturally receive their color.
No attempt is made to produce a given pattern, or to imitate any particular effect. The general tone of the color is produced and the variations of the tints are determined by the structure of the stone itself. In this way the effects are all natural. We have before us a piece of marble picked up in a common marble yard, of a cheap variety, one side polished the other rough, which has been colored by this process, and which the best judges invariably pronounce to be genuine Sienna marble.
The colors produced include the entire range of tints, and the veins and spots which develop themselves in marble, which previous to the operation is pure white, are surprising and beautiful. The cheapest grade3 of stone are thus rendered ornamental and desirable, and the combinations rendered possible by this discovery must arrest the attention of architects.
We do not exaggerate when we say that Some of the most excellent specimens of natural stones, celebrated for their beauty, seem dull in their colors when placed by the side of those prepared by this process.
Their adaptation to church architecture, as well as the adornment of private dwellings, will be admitted by all who inspect them.
