With the continuous progress of the world and the rapid development of science and technology, the stone carving industry has gradually developed, and there are more and more types of stone carvings, each of which has its own characteristics and value. Most of the stone sculptures that we often see in our daily life are made of marble. These marble sculptures have different shapes and colors, play a decorative role in our lives, and are deeply loved and favored by people. So, do you know what are the characteristics of marble sculpture? Here is a brief introduction to you:

Marble is a metamorphic or sedimentary carbonate rock, which belongs to medium-hard stone. Its chemical composition is mainly calcium carbonate, and its density is generally 2500-2600kg/m. The marble crystal particles are directly combined into an overall block structure, the texture is tight but the hardness is not large, the water absorption rate is less than 10%, the wear resistance is good, weak acid and alkali resistance, and no deformation. Pure marble is white, also known as white marble in my country. Ordinary marble presents various patterns such as red, yellow, black, green, brown, etc., with good color and texture effect and excellent decorative effect.

First, the resources are widely distributed, which is convenient for large-scale mining and industrial processing.

Second, the physical properties are stable, the organization is meticulous, the impacted grains fall off, the surface has no burrs, does not affect its plane accuracy, the material is stable, can ensure long-term deformation, small linear expansion coefficient, high mechanical precision, anti-rust, anti-magnetic, insulation.

Third, the material particles are fine and uniform, and the thickness of the crystal grain size is ever-changing; there are many colors, including red, white, gray, beige, yellow, green, purple, blue, brown, black, etc., and its texture patterns are numerous, including landscapes. Type, cloud type, pattern type (thread, willow leaf, image, paleontology, etc.), snowflake type, etc. The texture of marble is soft, beautiful and solemn, elegant in style, various in color, and can be processed in various ways. It is an ideal material for decorating luxury buildings and a traditional material for artistic carving.

Fourth, it belongs to metamorphic rock, its formation process is complex and diverse, and there are many kinds of minerals, so the material properties of different marbles are very different, such as the Mohs hardness is doubled from 2.5 to 5. Therefore, there are certain standards for the use of marble: the bulk density is not less than 2.6g/cm3; the water absorption rate is not more than 0.75%; the dry compressive strength is not less than 20mpa; the bending strength is not less than 7.0mpa.

Fifth, the texture is softer than granite, it belongs to medium hardness stone, has high compressive strength and good physical and chemical properties. However, the gap of its material is large, and it is accompanied by cracks and cracks, which is easy to break. The hardness of marble slabs is low. If used on the ground, the polished surface is easy to lose, so marble slabs are not used on the ground as much as possible, and marble is easily weathered, so it is best to use it for interior decoration.

Marble Carving not only decorates our living environment, but also enriches our spiritual life, and has become an indispensable part of our life.
