Because of the smooth texture, hardness and beautiful colors, the granite can be a supreme building material. Thanks to its anti-weathering character and stunning color, the appearance could remained for more than a hundred years. Granite has a low water absorption, rich colors and high luminosity. It is widely used in kitchen counter tops and outdoor ground decoration.
Well, do you know how to identify the quality of granite?
The first step, observe the surface. Generally speaking, the stone with uniform fine material structure has fine texture, which is the best stone material. However, the stone with coarse grain and unequal granule structure has poor appearance, uneven mechanical property and worse quality.
The second step, measure the size of stone specifications. So the decorative effect of pictures, lines and veins after stitching can be reserved.
The third step, listen to the percussion sound of stone. In general, stones with good quality, smooth texture and without cracks inside sound crispy and sweet. On the contrary, stones with micro cracks inside or uneven texture due to weathering sound gruff.
The fourth step, make some simple experiments. Usually we observe a drop of ink on the surface, if the ink disperse quickly, then there can be loose particles or micro cracks inside the stone, therefore, the stone quality is not good.
According to the above four methods, I believe you can quickly master the method of identifying granite.
