Decorative stone is a type of stone that can be processed into interior and exterior walls, floors, columns, countertops, etc. of buildings. From the perspective of material selection, it can be divided into artificial stone facing stones and natural facing stones. Generally, it refers to natural stone facing stone. As decorative stones, people not only achieve their decorative purposes from their color, pattern, and other aspects, but also from the decorative effect of the stone surface. The stone surface can be divided into the following ten aspects
1. Polished surface:. The surface is formed by rough grinding, fine grinding, and fine grinding of the flat plate with abrasive, and polishing with polishing powder and agent. This surface is shiny like a mirror, brightly colored, with few and very small pores. 2. Matte surface: It is formed by rough and fine grinding of a flat plate with abrasive, and its surface brightness and color are lower than the polished surface. This surface is relatively smooth and porous. This textured finish is commonly used in public places. The color on its surface is lighter than that on the polished surface.
3. Polished surface: It is formed by rough grinding of a flat plate with abrasive, and its surface brightness and color are lower than those of a matte surface. This surface is relatively smooth and porous. This texture finish is also commonly used in public places. The color of its surface is lighter than that of the matte surface.

4. Cutting surface: It is directly processed with a saw, with a matte surface and a lighter color, showing saw marks. Mainly used for finishes that require rough surface decoration. 
5. Burning surface: Using a mixture of acetylene and oxygen gas to spray and burn the surface of the stone board, causing the surface layer to burst and create a bumpy finish. Its surface color is relatively light, porous, and has a high water absorption rate.
6. Chisel surface: The surface of a stone obtained by using a steel chisel to pound it with a point like texture (also known as a lychee surface) or a strip like texture. The density and roughness of its texture can be chosen. The surface color is lighter, the pores are larger, and the water absorption rate is higher than that of the burnt surface.
7. Axe chopping surface: The striped surface obtained by pounding the surface of stone with a chopping axe. The density and roughness of its texture can be chosen. The surface color is lighter, the pores are large, and the water absorption rate is very high.
8. Sandblasting surface: A rough surface formed by the impact of high-pressure sand and water flow on the surface of stone, with a lighter color and uniform texture, but larger pores and high water absorption rate.
9. Mushroom surface: A mushroom shaped surface obtained by pounding the surface of stone with a steel chisel or chopping axe. Its texture is very rough, the surface color is dim, the pores are large, and the water absorption rate is also large.
10. Wedging surface: After manual or mechanical wedging processing, the slate has obtained a natural slightly rough texture finish. Its surface color is relatively dark, with small pores and low water absorption.
Purchasing and Maintenance Editing
Marble and granite are referred to as decorative stones:
At 60 centimeters × For example, 60 centimeters:
1. The thickness of the stone slab material should be uniform, not thinner than 1.5 centimeters, and the four corners should be accurate and at right angles. The cutting edges should be neat, and there should be no obvious mechanical patterns or explosive edges.
2. The brightness should be good, with no surface spots, and the brightness should be at least 80 degrees or above.
3. The surface pattern and pattern are uniform, without obvious mottled colors
