4. Lychee noodles (bush-hammered)
The lychee surface is made by hitting the stone surface with a hammer-shaped lychee skin, thereby forming a rough surface shaped like a lychee skin on the stone surface, which is more common on the surface of carvings or square stones. It is divided into two processing methods: machine and manual. Generally speaking, the manual processing surface is finer than the machine processing surface, but it is labor-intensive and time-consuming.

5. Longan noodles (chiseled)
Longan noodles are staggered and knocked on the stone surface with a flat hammer to form a rough surface like the appearance of longan skins.

6. Pineapple noodles (rough-picked)
A pineapple noodle is a plate that looks like a pineapple peel by hitting with a chisel and a hammer on the stone surface. Pineapple noodles are rougher than lychee noodles and longan noodles. Subdivision can also be divided into two kinds of thick pineapple noodles and thin pineapple noodles.

7. Antique noodles (flamed+brush)
In order to eliminate the thorny characteristics of the surface of the burnt surface, after the stone is first burned with fire, it is brushed 3-6 times with a steel brush, that is, the antique surface. The antique surface has the concave and convex feeling of the burnt surface, and it is smooth to the touch and will not sting. It is a very good surface treatment method. There are many ways to make antique noodles, such as water flushing after the fire, acid etching, direct steel brushing or high-pressure water flushing, and so on. The processing of antique noodles is time-consuming and expensive.

8. Mushroom
Mushroom surface refers to a plate that is shaped like an undulating mountain by hitting with a chisel and a hammer on the stone surface. This processing method has certain requirements on the thickness of the stone. Generally, the thickness of the bottom should be at least 3CM, and the raised part can be 2CM or more according to the actual requirements. Mushroom stones are widely used in economical fences.

9. Natural cleft
Natural surface refers to the processing method in which a piece of stone is naturally split from the middle with a hammer to form a natural stone surface. The natural surface is extremely rough, and it is widely used in small squares, curbstones, and other products. Like some unique stone varieties, such as slate, it is mainly used for its natural side, which can perfectly express the artistic conception of simplicity, nature, and infinite proximity to nature.

10. Machine-Cut
It is directly cut by a circular saw, sand saw or bridge cutting machine, and other equipment, and the surface is rough with obvious machine cutting lines.

11. Grooved
Open a certain depth and width of grooves on the stone surface.

12. Sandblasted
Instead of high-pressure water, the surface of the stone is washed with ordinary river sand or diamond sand entrained by high-pressure airflow, forming a smooth decorative surface with sandblasting effect.

13. Water-jet
The surface of the stone is directly impacted with high-pressure water, and the softer components are peeled off to form a unique rough surface decoration effect.

14. Brushed
The surface of the brushed surface is old, and the treatment process is to brush the surface of the stone with a resin brush or a wire brush, imitating the natural wear effect of the stone.
