Glutinous full green landscape jadeite As the saying goes, jade cannot be made into a useful object without being carved. Jade is known as the king of jade because of its high hardness, high specific gravity, and rich colors mainly emerald, jadeite and purple, and its raw materials (especially high-grade materials) are very rare and precious. Therefore, its processing procedures, processing materials, processing tools and processing equipment are different from those of other jades. The jadeite processing flow and procedures are introduced as follows: 1. Material selection : This is the key starting point. Jadeite jade materials generally have skin. It is the only jade with skin in the world, so it is also called gambling stone or gambling goods, which is something that other jades do not have. So, the primary consideration in material selection is the processing purpose, to make ornaments? Device? bracelet? Pendant? Rings or ring faces, etc. The characteristics of raw materials are closely related to the processing purpose. If the selection is poor, not only will the raw materials be wasted, but the processing will also result in a loss. 2. Cutting : This is also the first step. Some people are eager to gamble on the stone and usually cut it with one cut. Not only may the jade be cut off (because good jade is usually thinner), but it may also fail to make the whole sculpture artwork, thus losing its original value. Usually the general procedure is to wipe the skin first to look at the surface characteristics of the jade, such as the direction of the emerald color, the development and direction of cracks, the tones of jadeite and purple, the distribution of black, the analysis and estimation of the changes in the water quality inside and outside, and the appearance of the original stone. Secondly, it is determined based on the overall condition of the original stone and its possible processing purposes. Then, decide whether to use the entire raw material for carving or cut it into pieces. 3. Usage positioning and design : 1. When making small items: consider the purpose and yield rate. Such as round carvings and bracelets. 2. Make small carvings: such as jade pendants and waist plaques, etc., you need to consider what style to make, which can both utilize the advantages of the raw materials and meet the requirements of the carving style. Otherwise, it is easier to produce waste products. 3. Making ornaments: The choice of theme style is closely related to the characteristics of the raw materials and is a very important link. If you are designing a figure, the first thing to do is to see if there are any foreign objects in the original stone, or to choose a cleaner part for the figure's face. You also need to consider whether the original stone is large enough to fit the figure's proportions. Perfect jade artifacts are all jade works of art created through creative design and meticulous craftsmanship. The principle of carving design is to maximize the value of the original stone based on its color, type, water, shape, cracks, black color, and jade quality. Usually the styles of carvings: figures, mountains, auspicious objects, animals, and flowers have different requirements for raw materials. The main style of the carving and the matching supporting style are principled and proportional, rather than a simple accumulation of styles. 4. Processing process : 1. Cutting: 1. Small pieces: Cut into sizes with different specifications for different uses in steps, and change the processing purpose of the pieces that cannot be used or do not meet the specifications to make the best use of them. 2. Ornaments: Cut into rough pieces according to design style requirements. 2. Carving 1. Rolling: Use a fine rolling mill to carve out shapes of figures, animals, landscapes, flowers, etc. Such as faces, animal bodies, roots, stems and leaves of trees and flowers. 2. Hook: Use a hook or various shapes of nails to hook out fine patterns, such as human hair, beard, phoenix hair, animal hair, scales and plant leaf patterns. 3. Finishing: Usually large and powerful factories are equipped with this process, using special tools and materials to smooth out the excess marks and sand holes from the previous carving process, laying a good foundation for the next grinding and polishing process. 3. Grinding and polishing process 1. Polishing: (1) Manual grinding: It is semi-mechanized and is done manually using a grinder and various diamond grinding wheel tools, from coarse grinding to fine grinding, and from fine grinding to matte finishing. (2) Machine grinding: It is fully mechanized and uses diamond sand on a vibration machine to complete the processes from coarse grinding to fine grinding and precision grinding. Usually it takes 3 to 4 days to polish a small round-carved jade piece. 2. polishing: 1) Manual polishing: Manual polishing is done using a polishing machine, various polishing tools and polishing materials to create a bright finish. 2) Machine polishing: Vibrating machine plus polishing materials. Usually, it takes 2 to 3 days to complete a small round jade carving. Manual grinding and polishing usually takes longer and is more expensive than automatic machine grinding and polishing, but the effect is better and it preserves the three-dimensional and carved style of the carved patterns. (IV) Decoration: 1. Decoration of ornaments: The base is the most critical decoration of ornaments. There are many materials and styles for the base of ornaments. A good match can improve the artistic value. 2. Packaging: This is the last link. A beautiful jade product needs good packaging, including inner and outer packaging. The matching packaging can not only beautify the product, but also protect and transport it.
