1. grinding

The surface is smooth and slightly glossy. Different glossiness can be selected. The surface is very smooth, but porous. This kind of surface is common in many places where people walk. Because of the large aperture of ground floor, permeable sealant should always be used. The color of polished stone is not as bright as polished surface.

2. polishing

The surface is glossy, after a period of time, it will lose its gloss because of too many pedestrians and improper maintenance. The surface is smooth with few holes. After polishing, the reflection of the crystal produces brilliant color, showing the mineral particles of natural stone. The luster comes from the natural reflection of the stone crystal. The polishing surface is formed by using polishing bricks and polishing powder in production, and the gloss is not produced by coating.

3. burn

The surface is rough and forms at high temperature. When the stone is heated in production, the crystal bursts and the surface is rough. Surface porous, must use permeable sealant.

4. roll over

The surface is a bit rough, turning fragments of marble, limestone and sometimes granite into old-fashioned forms by rolling them in containers. It is often necessary to use a stone colorizer to make the colour more distinct.

5. sandblasting

Sand is sprayed onto stone by high pressure jet of sand and water to form a glossy but not smooth surface.

6. chopped axe

By hammering, surface texture can be formed and roughness can be selected.
