Natural marble and man-made stone do kitchen table which is good?
First, natural marble has radiation, the human body is hurt, man-made does not exist this problem.
Second, the permeability of natural marble than man-made strong. Permeability is that if you put the color of liquid on the natural marble countertops, the color will penetrate into the table inside, can not clearly leave a permanent trail; and artificial marble permeability is poor, the color penetration is slow, if the timely clean It will not leave traces.
Third, the price is different. Natural marble is expensive.
In addition, in the pattern and color selection, man-made richer, homeowners can choose their favorite color
Marble is mainly composed of calcite, limestone, serpentine and dolomite. The main component of calcium carbonate-based, accounting for more than 50%. Because marble generally contains impurities, and calcium carbonate in the atmosphere by carbon dioxide, carbide, water vapor role, but also easy to weathering and erosion, leaving the surface soon lost luster. Marble is generally of a relatively soft nature, which is relative to granite.
Marble is the crust in the original rock through the crust in the formation of high temperature and high pressure metamorphic rocks. The internal forces of the crust have led to changes in the quality of the original rocks, that is, the structure, tectonics and mineral composition of the original rocks have changed. The new rocks formed by qualitative change are called metamorphic rocks.
Natural stone Natural stone is divided into two types: marble and granite. In general, there is a texture, called "marble"; to spot the main, called "granite." This is in a broad sense. From the narrow sense, the marble refers to the marble produced in Yunnan Dali. In fact, now the country is not much stone is Dali out.
The two can also be distinguished from the geological concept. Granite is igneous rock, also known as acid crystal deep diagenesis, is the most widely distributed igneous rock, composed of feldspar, quartz and mica, rock hard and dense. Its composition to silica-based, accounting for about 65% -75%.
