The original Marble is mineral calcite (CaCO3). Of course, in addition to calcite, there are other Minerals in the structure of this stone. These materials include:
- Clay
- Mikas
- Quartz
- Pyrite
- Iron oxides
- Graphite
Marble can be mined in various dimensions. The Stone has its own unique features and in the following you are familiar to them.
Marble is light color. More purity limestone in the Rock caused more white it is. Impurities such as clay, iron oxides or tarry materials makes the color of the background or streaks of blue, gray, pink, yellow or black in this stone . One of the interesting facts about marble is high purity applications that are in various industries. We will introduce these applications in the next section.
Checking the Hardness of Marble
There calcite in marble makes it difficult to it to be able to cut well. It makes the use of marble in the build artifacts such as statues and have a great application. This feature, along with increased transparency of the stone so beautifully realized structures are not using this stone.
Abrasion-Taking and Polished Surface
Abrasion-taking of marble leads transforming it into one of the precious and valuable Stones of the building. The stone is then polished and attractive surface gloss and installed as a facade, wall coverings, flooring and unique parades to the building.
Resistance to Environmental Conditions
Marble can be resistant to most rock against the environmental conditions such as humidity, heat and cold. The rock also has good resistance against rain and acidic rain. Stone structure is in a way that is rarely infected, and keep its beauty for a long time.
Other features marble are as follows:
- Beauty
- Usability and design features
- Modern and classic interior
- Heat insulation and energy conservation
- Cool and do not absorb heat
- Anti-allergy
Marble is one of the most beautiful ornamental stones known. What has attracted the most attention from marbles is their intricate designs and natural colors. There are more than 40 types of marble for interior decoration, each with a different color and shape from other marbles. First of all, it is better to get acquainted with marble, its specifications and applications. Marble, or marble, is derived from the Greek word marmarom, meaning crystal clear stone. Marbles classified into different categories in terms of strength and other mechanical properties. Some marbles have high strength and resistance. Therefore, these marbles are mostly used indoors. The construction of the statue, the interior and exterior of the building are the main uses of marble. Given the variety of colors in marbles, the question arises as to what are the causes of color differences? To answer this question accurately, it is necessary to examine the influential factors in this phenomenon. The rocks extracted from different regions show that factors such as the geographical area of ​​the quarry and the composition of the raw materials affect the properties of the formed marble. In fact, these minerals cause pigmentation in marbles. Currently, marbles extracted from various quarries around the world have white, green, yellow, black, red, pink, and so on. Marble is usually a light-colored rock formed by the transformation of limestone or dolomite. The beautiful and amazing designs and colors that you see in marbles are formed as a result of the presence of impurities as well as the physical conditions of the environment. -Iron oxide: The cause of yellow and brown dyes in marbles is iron oxide. An increase in the percentage of marble iron tends to red background and an increase in rock feldspar. -Serpentine: Sarpentine is a group of green minerals that contain different amounts of iron, nickel, manganese, zinc, magnesium and silicon in their structure. Now the presence of this group of minerals in the composition of limestone creates a wide range of green colors. These compounds cause purple color in marbles. -Sulfur: Although it is removed at high temperatures, it is one of the reasons for the yellow and brown color in marbles . -Bitumen and graphite: The presence of any of the compounds of graphite, bitumen and coal in limestone is a factor in causing opacity in marbles. Black marbles are one of the most beautiful and luxurious ornamental stones formed as a result of the transformation of graphite and limestone. - Chromium: The presence of golden streaks in some types of marbles indicates the presence of chromium in the composition of limestone or dolomite. -Manganese: This element is present in varying amounts in some marble stones. Experts recognize the presence of this element on the veins and purple pattern in the appearance of marble. In addition to the impurities mentioned, many other minerals may be present in the composition of limestone. The interaction of these minerals in different parts of the globe leads to the formation of marbles of different colors and patterns. Heat: Because marble is formed in deep of the earth, it is exposed to significant heat from the earth. As a result, we can see different colors of marble at any depth of the earth. - Pressure: Accumulation of limestone and other minerals over time leads to excessive pressure on the rocks below. - Time: Depending on how long it has been since the burial of the carbonate material, the color and appearance and even the mechanical properties of the marble will be different.
