1. Marble carving art-round carving

Round carving, also known as three-dimensional carving, is the overall expression of art on carvings. The viewer can see the sides of objects from different angles. It requires the sculptor to sculpt from the front, back, left, right, top, center, and bottom. It is the most basic technique in stone carving.

Circular carvings are generally "carved" from the front, and at the same time require special attention to the unity and harmony of the various angles and orientations of the works. Only in this way can the circular carvings withstand the full range of the viewer.

Because the round carving works are very three-dimensional, vivid, lifelike, and expressive, the selection of marble for round carvings is relatively strict. From length to width to thickness, it must have an appropriate proportion to the real thing, and then the engravers will "play blanks" in proportion. "Blanking" is the first procedure in circular carving, and it is also an important link. Especially for large-scale circular carvings, you also need to "blank" on the clay first, and then formally put it on the marble after the revision of the "mud draft". "Playing billet". The purpose of "blanking" is to ensure that each part of the sculpture can be regulated by strict proportion requirements, and then use the knife to sculpt the works that are vivid and vivid.

With the passage of time, the subject matter of stone carvings has been continuously expanded, and stone carving techniques have also been enriched and developed. On the basis of round carving techniques, there are carving and chain carving. In terms of content, it has also developed from independent individuals to large-scale group sculptures combining characters, animals, landscapes, etc., which makes the circle carvings more rich and perfect from the technique to the content of the work. The same round carving work is often combined with multiple techniques such as round carving, skeleton carving, and chain carving.

2. Marble carving art-carving

Carving is also called hollow, that is, hollowing out the part of the stone that does not show the object image, and keeping the part that can express the object image. Based on the difficulty of engraving, it is different from the general engraving techniques from stone selection, work layout, tool configuration to engraving procedures, etc. The carved stone must be pure and fine, especially the hollow part, and there should be no cracks and high-density sand grids, otherwise, it will easily cause a fracture. In addition to the general carving knives, the tools used for engraving also need special tools such as special long-arm chisels, pick picks, shovel bottom knives, hook knives, and small saws. Since the engraving of the internal scenes uses the method of directional orientation to overcome the operational difficulties, the design requirements of the engraving scenes are best to be multi-faceted. Generally speaking, the more the direction of penetration, the denser the cavity, the easier the carving and the better the effect. The engraving procedure is "outer first then inner", and the engraving can only be carried out after the blanking and chiseling of the outer sceneries and other backgrounds are completed.

Marble has beautiful colors and patterns, high compressive strength, and good physical and chemical properties. The resources are widely distributed and easy to process. With the development of the economy, the application range of marble continues to expand, and the amount is increasing. Plays an important role. In particular, the large-scale mining, industrial processing, and international trade of marble in the past decade have made marble decorative plates enter the building decoration industry in large quantities, not only for luxurious public buildings but also for home decoration. Marble is also widely used to make exquisite utensils, such as furniture, lamps, smoking sets, and artistic carvings. Some marbles (including limestone, dolomite, marble, etc.) can also be used as alkali-resistant materials. The crushed stone and corner residue produced in the mining and processing of marble are also commonly used in the production of artificial stone, terrazzo, stone rice, and stone powder. They can also be used as fillers in coatings, plastics, and rubber industries.

3. Chemical laboratory application

In the chemical laboratory, Dali or limestone (mainly calcium carbonate CaCO3) is reacted with dilute hydrochloric acid to produce carbon dioxide.
