The classification of the common decorate stone material

Decorate stone species: mainly marble, granite, terrazzo, synthetic stone, etc.How to choose the kind decorate stone material, according to the different used purpose and personal economic ability.Here we detailed introduce to decorate stone material classification and variety.
Natural stone in daily use are mainly divided into two kinds: marble and granite.
In general, anyone who has a texture, called the marble, the mainly point spot called granite.This is from the broad sense.From the narrow sense, refers to the yunnan Dali produced stone marble.In fact, now throughout the country a few stone to Dali.
The two also can distinguish from geological concept.Granite is igneous rock, also known as acidity crystallization plutonic rock, is one of the most widespread in igneous rock, rock is composed of feldspar, quartz and mica, its composition is given priority to with silica, accounts for about 65% ~ 75%, rock hard and dense.Alleged igneous rock is subterranean magma or volcanic eruption of lava condensation crystallization of rock.Igneous rock, feldspar content of silica in the nature and content of determine the nature of stone material.More than 65% when the content of silicon dioxide, belongs to the acid rock, the rock of potash feldspar, plagioclase, quartz and other essential mineral crystal formation, a granular structure, are called granite.
Marble is the rock in the lithosphere forms through action of high temperature and high pressure inside the earth's crust of metamorphic rocks.All kinds of internal force in the earth's crust makes original rock of qualitative change process.Qualitative change refers to the original rock structure, the structure and the change of the mineral composition.After a qualitative change to form new rock type are called metamorphic rocks.Marble is mainly composed of calcite, limestone, serpentine and dolomite.Its main composition is given priority to with calcium carbonate, which accounts for about 50%.Other and magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide.Because marble is generally contains impurities, and calcium carbonate by carbon dioxide in the atmosphere, carbide, the effect of moisture, also easy to weathering and dissolution, and make the surface soon lose its luster, marble general nature is soft, it is relative to the case of granite., of course, you don't have to listen to this, because the geological time is calculated by the billions, in our lifetime, this qualitative change is a change in the limited.
The above marble and granite, of course, in the classification of the above, is a relatively narrow sense definition.Now on the market, generally are texture of metamorphic rock, so also known as the marble.And show some spot crystal particles, also known as granite.In fact, too detailed classification, that is a geologist, for indoor decoration, almost.Of course, if your stone used in outdoor, because the environment is relatively poor, requires a detailed classification.
Because of natural stone material surface pores, so weak in terms of fouling resistance.Generally in factory will be on the surface for processing.In indoor decoration, television mesa, windowsill, indoor ground suit to use marble mesa.And the threshold, kitchen table, ground outdoor suits to use granite.The kitchen table had better be to use brunet granite.
Now on the market sales of natural stone material, part of the colour and lustre is through artificial processing, these stone commonly used about a year and a half to will reveal its true face.The most obvious is the dark green now on the market, many of them are dyed, and is not the real dark green.
