Relief is a kind of sculpture. The sculptor carves the image he wants to shape on a flat plate, making it separate from the plane of the original material. Relief is the product of the combination of sculpture and painting. It deals with objects in a compressed way, and displays three-dimensional space by perspective and other factors. It is only for one side or two sides to see. The reliefs are usually attached to another plane, so they are used more in architecture and can be seen on utensils and implements. Due to its compression characteristics, it occupies less space, so it is suitable for decoration in a variety of environments. In recent years, it has played an increasingly important role in urban beautification. The relief is as rich and colorful as the round sculpture in content, form and material. The materials of relief include stone, wood, ivory and metal. The relief is a semi vertical sculpture whose image shape protrudes from the stone surface (as opposed to the relief). According to the different depth of stone removal in image modeling, it can be divided into low relief and high relief. The bas reliefs are single level statues with relatively simple contents; The high relief is a multi-level statue with complicated contents. The carving technique and expression style of relief are basically the same as those of round sculpture. Many ancient and modern large-scale memorial buildings, high-end mansions and private houses are equipped with such decorations. Their main works are wall blocks, flower windows, dragon columns (early) and column bases.

Marble, granite, Hui'an stone, Qingtian stone, Shoushan stone, Guicui stone and other materials are generally used for stone carving. Granite and marble are suitable for carving large statues; Qingtian stone and Shoushan stone are rich in color, which are more suitable for small stone carvings. There are many ways to make stone carvings. According to the nature of stone materials and the habits of the carvers, stone carvings can be roughly divided into two types: first, traditional methods. Conception, composition, modeling and stone carving are all done by individuals alone. For large-scale carving of lines, the horizontal and vertical lines shall be drawn on the stone, the grid shall be made to take materials, and the simple measurement and positioning method shall be used for carving. The second is to adopt a new process, that is, first make a clay sculpture, turn it into a plaster statue, then take the plaster statue (model) as the basis, rely on the point shaped instrument, and then carve it into a stone statue.

Jade carving, commonly known as jade ware, has a long history. Jade pendants appeared in China during the Neolithic Period, and the jade carving skills of the Shang Dynasty were relatively mature. There are dozens of jade carving materials, such as white jade, jasper, sapphire, black jade, jadeite, crystal, agate, topaz, single jade, Xiuyu, etc. Guangdong EPS exterior wall Because the jade itself is fine, hard and warm, or white as cream, or green and green, bright and lovely color, suitable for making valuable decorations. As for the production of jade, most people think it is carved with a carving knife, but it is not. EPS exterior wall Price The jade is hard, and the carving knife cannot cut it into it. Instead, it is polished by various shapes of drill bits, emery and water, depending on the shape of the work. Therefore, it takes a long time to complete a jade carving.

The traditional method is to brush lime water or wall powder, but it is easy to be polluted and cannot be scrubbed with wet method. It is mostly used for general buildings. More advanced buildings use flat ready mixed paint as decoration material, which is rich in color and is not easy to be polluted, but the volatile amount of organic solvent mixed in is large, which pollutes the atmosphere and affects the health of construction personnel. With the development of science, organic synthetic resin raw materials are widely used in paint, making the appearance of paint products fundamentally changed, so it is called paint, It has become an important interior and exterior wall decoration material. There is a long history of papering interior walls and ceilings, but it has been replaced by plastic wallpaper and fiberglass wall covering. Hainan sculpture gypsum board has the characteristics of fire prevention, sound insulation, heat insulation, light weight and high strength, and convenient construction, which is mainly used for walls and flat roofs; When making a flat roof, holes with various patterns can be punched to improve the sound absorption and decoration effect. Calcium plastic board has a good decorative effect, can keep warm and sound, and is a multi-functional board. Marble and granite plates are increasingly used to decorate high-end hotels and apartments.

Micro carving is a kind of carving technique that is good at small and fine. Chinese micro sculpture has a long history. Miniature carvings appeared in oracle bone inscriptions as far back as the Shang Dynasty. During the Warring States Period, the seal was as small as millet, but the seal was divided into white and black. Wang Shuyuan's Nuclear Boat Story, which is widely known, is also a classic work of micro sculpture in Chinese history. The art of seal cutting is the basis for the emergence and development of micro carving art. Since the Ming and Qing Dynasties, many literati and scholars have used iron pen to write and paint in the seal, to express their interest and entertain themselves. After Shoushan Stone became the seal material, the micro carving art of Shoushan Stone began to appear. At the beginning of the Qing Dynasty, Yang Xuan and Diaobin both carved small characters in the remote patterns of Shoushan stone carvings. Lin Qingqing, a master of "Ximen Boyi School" carving, also often wrote his name and date of production in the grass and stone crevices of the carved works with extremely fine pen. Later, some people carved ancient poems with extremely fine characters on the four sides of the square pillars of the seal as margin. In the 1960s, with the application of advanced scientific instruments such as magnifiers in the field of micro sculpture, micro sculpture art became a new and unique art. The words carved in the works are smaller and smaller, and the content is more and more. Microcarvings pay special attention to the selection of materials. The texture of the Hainan EPS component stone is required to be absolutely pure, and there should be no sand grid and half silk cracks, because half of the sand dot may be engraved with more than 10 Chinese characters. Secondly, the micro carving knife is also a special thin knife, which should be sharp and sharp. Third, it is necessary to have a particularly proficient knowledge of calligraphy and traditional Chinese painting. When carving, you can carry out "free engraving". Fourth, hold your breath and concentrate on your thoughts on the spot. Fifth, the knife should be handled steadily, accurately and ruthlessly. Only in this way can calligraphy and knife technique be perfectly unified. The art of micro sculpture is "art in micro". The more subtle it is, the more refined its kungfu is, and the higher its value is. Microcarving is also an art that pays great attention to the picture and organization, which is "intended to be refined". The sculptor of micro sculpture should first have a deep knowledge of calligraphy and painting. Although the micro sculpture is too small to be recognized with the naked eye, it is still very exquisite under the magnifying glass, such as large calligraphy works.
