Spraying crushed stone onto stone with a high-pressure stream of a mixture of sand and water will form a surface with a certain gloss but not smooth. This can improve the gloss of the stone.

 

 

The surface has a gloss, but it will gradually lose its gloss over time due to pedestrians and improper maintenance. Features The surface is smooth. After polishing, the slate reflects brilliant colors, highlighting the mineral particles of natural stone. The gloss is the reflection of natural light from the stone particles. In production, the glossy surface is formed by high-speed friction between the polished stone and the slate. The gloss does not appear by applying the material.

 

 

After the stone surface is polished and flat, it has a micro-gloss, and different gloss levels can be selected. The surface is smooth, but there are pores. This kind of outer surface is more common in places with more pedestrians, also called matte surface. Because the aperture of the polishing is larger, penetrants are generally used. The color of the polished stone is not as obvious as the polished surface.

 

 

The machine-cut surface of the stone is rough, and after high-temperature firing, it will form a rougher antique surface, called the burned surface. After the surface of the stone is heated by fire, the surface of the stone slab will crack, a layer of skin will fall off, and the surface will be rough with many convex and concave marks.
