The color of granite depends on the minerals it contains. The reason why the curbstone is yellow is mainly because this type of stone contains more limonite, as well as a small amount of quartz and mica. Therefore, some curbstones have alternating colors of yellow, gray, and white. If there is too much mica in granite, the stone will turn black, too much plagioclase will turn white, and too much potassium will turn red. When multiple minerals are mixed together, the colors of particles of different colors will be evenly mixed together, which is very beautiful. The name of curbstone is based on the physical image and color of the stone pattern, hence it is called curbstone. This type of stone is very suitable for the construction industry.
How to purchase curbstones? How can I buy curbstones?
We should choose to purchase curbstones during the rainy season, because when we purchase curbstones during the rainy season, we should choose some dry curbstones to adapt to the surrounding humid environment; Secondly, some curbstones may appear intact on the surface, but they all have a characteristic of relatively large color differences, which can make buildings or other things that use a large number of curbstones of the same color incomplete as a whole;
Another point is that we usually don't pay much attention to whether there are defects in the surface texture of the curbstone. If there are some irregular traces, there is no way. The curbstone may have been caused by some environmental factors during the generation process, but if there are some regular traces, it may have been caused by human factors during the later processing. You can measure its quality based on its market price and then determine whether the curbstone in your hand is a good curbstone.
