What is marble? Distinguish between Marble and Granite
Marble and granite are both stones found in nature. Despite some basic similarities, they still have significant differences. Therefore, based on the tiling location as well as the needs of use, choose the right material for your needs. However, before deciding, please read the article below to understand more about these two expensive natural stones. As well as knowing what is the safe construction method, ensuring the quality of the project.
Marble – How is natural marble formed? What are the characteristics?
Marble (also known as marble) is formed from the metamorphosis of limestone. Their main composition is calcite minerals (CaCo3 carbonate), clay, micas, dolomite, pyrite, iron oxide and graphite. From the original carbonate crystal particles, combined with other minerals and strong heat and pressure when buried deep in the ground for a long time… has formed rock – is a mass of interlocking calcite crystals.
Specifically, pure white marble is the result of metamorphosis of very pure silicate-poor limestone or dolomite protolith. The vortices and ridges characteristic of many colored marbles are usually due to other minerals and impurities such as clay, silt, sand, iron oxide. The green color is usually caused by serpentine produced from limestone or dolomite rocks rich in magnesium and silica impurities.
With expensive sparkling beauty, marble is widely applied in unique construction works, showing luxury, class, luxury, authority, stability … such as temples, royal palaces, villas, commercial centers … Some famous architectural works in the world using marble can be followed by the Taj Mahal (India), Lincoln Memorial (USA), Supreme Court Building (USA).
Marble – What is the difference between marble and granite?
Origin
Granite is derived from the melting and solidification of magma from deep in the ground over long periods of time. Thanks to this slow heating and cooling process, granite becomes an extremely hard material. Granite is composed mainly of Feldspar, quartz … are very hard minerals.
And marble, as shown above, they are basically derived from limestone, which also spends long periods underground to metamorphose into marble. This type of marble is composed mainly of Calcium carbonate, so it is much softer and more porous than the components of granite.
Shapes and colors
Many people are often confused between marble and granite because they have a somewhat similar appearance. However, upon close inspection, you will discover countless differences between marble and granite, especially in their natural color variations.
For granite, variations often appear as speckles throughout the surface of the rock or as black granite forms. The color variations of marble are like colorful cloud fins swirling through the rock. These marbles are rated as having vivid ridges, the freshest color in any natural stone.
Durability
The process of natural formation will have a correlation with the strength of marble as well as granite. Although they are all considered to be durable materials, it is important that you choose the right material for the tiling area so that no damage occurs after a short time of use.
Granite has a hardness of 6 – 7 on the Mohs scale. Granite has high scratch resistance and good heat resistance, so it does not fade and yellow during daily activities. This is the ideal material for wall cladding, floor paving, kitchen counters and various interior areas.
Marble has a hardness of 3 – 5 on the Mohs scale, therefore their hardness is not equal to granite. When in contact with pans, hot dishes, this type of marble can be damaged. However, there is a stone called Danby Marble mined in Vermont that is considered to have better hardness than traditional marbles such as Carrara or Calcutta. And now this stone is becoming a trend in the construction of the kitchen area tiling area.
Resistance to stains, resistance to yellowing
The porosity of marble will make them easy to absorb water, liquids … when exposure. Wine, fruit juice, lemon juice, vinegar… can seep into the marble layer and cause stains.
The ultra-low pore structure makes granite resistant to most liquids and food, as long as you apply an effective waterproofing layer to them.
Waterproofing, stone glue and rub glue
Both granites need to be thoroughly tipped to ensure aesthetics and safety. Before installation, the professional worker will perform waterproofing, using stone glue for paving marble and granite. After paving the stone on the surface, ron rub glue will be used to trim the interstitial lines to prevent stone peeling and damage.
However, compared to granite, marble has porous properties and is more permeable to water. Therefore, it is necessary to waterproof, rub the brick ron thoroughly to avoid water seepage, dirt creeps into the crevices, causing staining, losing the original beauty of the marble.
In addition, marble construction is also more difficult because they are quite fragile, broken … but it is difficult to find similar products to replace. Therefore, the construction price for marble is also higher and you also need to pay attention to invest in finding professional, highly skilled contractors and quality and suitable tiling materials.
How to clean the surface of brick and stone?
Marble and granite surfaces should be regularly cleaned with soapy water to keep their surface shiny and clean. However, be sure to clean it with clean water to remove the soap completely.
Particularly for marble, because the stone structure is more porous, it should be cleaned carefully to avoid damaging the stone. It is recommended to use cleaning products with a neutral pH to avoid fading marble.
