when shopping for decorative stones, consumers can distinguish their quality from the following:

appearance

commonly used decorative stones mainly include marble and granite

generally speaking, marble has fine texture, changeable patterns, bright color, and is easy to process and polish, but its hardness is low, and its wear resistance is worse than granite. It is mainly used for the finishing of indoor floors, walls, windowsills and columns

granite is characterized by dense structure, low water absorption, hard texture and high strength, especially the compressive strength can reach 1200-2500kg/cm2. As the main constituent minerals of granite have strong resistance to acid, they are extremely resistant to acid corrosion and alkali corrosion

granite is not easy to be weathered and deteriorated, and its appearance and color can be maintained for more than 100 years, so it is mostly used for exterior wall finishes. Because of its strong corrosion resistance to acid in the air, its hardness is higher and wear-resistant than that of marble. In terms of durability, it is beyond that of marble, terrazzo and other stones. Therefore, it is an ideal natural stone for architectural decoration. Compared with marble, granite changes less in color and pattern, but it has more flexible changes in texture. At the same time, it appears more solemn and classical in the overall feeling

quality

the material of stone should be uniform and complete to avoid dark cracks, black scars and color differences

1. Pay attention to the composition of the stone and avoid containing too much harmful substances such as iron sulfide, iron oxide, carbon and clay

2. Pay attention to the radiation level of stones

3. Pay attention to whether the stone contains mineral components with high thermal expansion coefficient, thermal conductivity and conductivity, so as to avoid the risk of cracks, thermal conductivity and conductivity

durability

stones with uniform pore distribution, small pore size, low water absorption, high hardness and compressive strength should be selected as far as possible. However, it should be noted that although the strength of stone materials with heavy weight is higher, it will increase the load of the structure and reduce the strength and seismic capacity of the house
