How to distinguish the quality of Marble Sculpting?

1. The pattern and tone of the surface are not beautiful. As a decorative stone carving, the main value is the decorative effect on the surface after processing. The physical and chemical performance indicators are poor, and the stone sculpture used for decoration are often based on their decorative performance, that is, the color pattern, gloss and appearance quality of the Marble Sculpting surface, etc.) as the requirements for material selection, but when evaluating the quality of stone sculpture, in addition to considering the decorative performance, Other quality indicators should also be considered, such as compressive strength, flexural strength, durability, frost resistance, hardness, etc.

2. The size deviation of Marble Sculpting is too large. Decorative stone lions are all processed into plates for use. The method of collage (for the ground) or collage (for the wall) is used for construction. In order to ensure that the decorative surface is smooth and the joints are neat, the national standard stipulates the deviation of the length, width and thickness of the board, as well as the limit tolerance of the flatness of the board surface and the angle of the front and side.
3. The appearance quality of the processed plate is poor. The surface characteristics of Marble Sculpting are revealed after cutting, sawing, grinding, polishing and other processes. In the process of processing, some defects will be left on the appearance of the Stone Carving surface. If these appearance defects exceed the scope stipulated by the national standard, the stone carving is a substandard product. Using these inferior boards with poor appearance quality for finishing decoration, the overall decorative effect will not be satisfactory.
4. Marble Sculpting Therefore, when judging the quality of stone sculpture, it is recommended that in addition to considering the color of the pattern, the appearance quality must also be checked. Marble Sculpting are usually made of granite and marble. A small number of Marble Sculpting are made of sandstone, mainly sandstone wall carvings and sandstone reliefs. Marble Sculpting carved out of different materials have different preservation times.
5. As a high-density granite, it has a hard texture, corrosion resistance, and weathering resistance. The preservation time and the preservation of the original appearance of the stone carving are the better ones among the three materials, but the carving difficulty is also higher. Marble, such as white marble statues and beige stone carving products, has its own reticular texture, and its density is slightly lower than that of granite, but it is also extremely strong and is not afraid of wind and rain.
6. Sandstone is thicker and looser, so it is often used as a wall decoration. Although it also has the characteristics of stone resistance to corrosion and weathering, compared with the above two stones, it must preserve its original appearance. The time is much shorter.
