Jadeite is known as the king of jade because of its high hardness and high specific gravity and rich colors mainly composed of emerald color and purple, as well as 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 other jade. The process and process of jade jade jade are now introduced as follows:
First, the choice of materials:
This is an important beginning. The jadeite jade has many leather shells. It is the only jade stone with a leather shell in the world. It is also called gambling stone or gambling goods. It is also not available in other jade. Therefore, the key to material selection is processing and making ornaments? Device? bracelet? Pendant? The ring is still a ring face. The characteristics of the raw materials are closely related to the processing use. If the choice is not good, not only the raw materials are wasted, but also the processing will result in a loss.
Second, the opening:
It is also a key link. Some people are eager to gamble, often slashing down, not only may cut the green (because the good green is often thin), but also may not be able to do the overall engraving of art, losing its original value. Generally, the normal procedure is to first look at the surface features of jade, such as the direction of the emerald, the development and orientation of the fissure, the color of the ochre and purple, the distribution of black, the analysis and estimation of the variation of the water inside and outside, and the shape of the original stone. Secondly, it is determined according to the overall condition of the original stone and the use of the processing. Then, decide whether the whole material is carved or cut.
Third, the use of positioning and design:
1, do small pieces: consider the use and yield. Such as round carvings and bracelets.
2, do small carvings: such as jade and waist cards, etc., to consider what kind of pattern, not only the advantages of raw materials, but also meet the requirements of the carving pattern. Otherwise, it is easy to waste.
3, do the ornaments: the choice of the theme pattern is closely related to the characteristics of the raw materials, is a very important and primary link. For example, if you are designing a character, the key is to see if the original stone has impurities, or if the clean part is the face of the character, and whether the original stone is enough for the proportion of the person. The perfect jade jade is a jade jade artwork that has been creatively designed. The design of the carvings is based on the original stone color, species, water, shape, crack, black, jade and other characteristics, the principle of raising the original stone to the maximum value. General carving patterns: characters, mountains, auspicious, animal, and flower have different requirements for raw materials. The motif motifs and matching patterns are principled and proportioned, rather than a simple stack of patterns.
Fourth, the processing process:
a, cutting:
1. Small pieces: Step-by-step cutting into the size of different application specifications, changing the processing materials for which the sheets cannot be used or not meet the specifications, and achieve the best use.
2, ornaments: according to the design pattern requirements, cut into a rough.
b. é“¡: Further use the diamond grinding wheel (coarse sand) to further remove the useless part into a rough blank.
c. 錾: The diamond (medium sand) grinding wheel is used to further remove the convex and concave portions and the useless parts of the entire surface.
d. Punching: The rough blank of the previous process is further punched into a rough blank by using a diamond grinding wheel or a round file.
e, grinding: grinding all kinds of blanks, such as fruits, rocks and roots, with various specifications.
f, carving:
1. Rolling: Use the rolling squeegee to make the shape of the characters, animals, landscapes and flowers. Such as open face, animal body and trees, flowers, roots and leaves.
2, hook: use hooks or nails to trace the fine lines, like human hair, beard, phoenix hair, animal hair, scales and plant leaf lines.
3, the light: generally large and powerful factories have this process, using special tools and materials, the front engraving process extra scoring and sanding flat, laying a good foundation for the next polishing process.
Fifth, the carving method:
China is an ancient country with a history of more than 7,000 years of civilization. Then jade processing has a history of 7,000 years. In the long history of jade carving, our ancestors have created very advanced jade tools and jade carving methods. We will introduce a lot of commonly used parts of jade carving methods as follows:
1. Relief: refers to embossing, bas-relief, deep relief; pretty color carving. Such as: Fu Lu Shouyi and so on.
2, openwork: refers to the transparent sculpture, there are cross-cut empty carvings, there are round transparent carvings, there are decorative ornaments and so on. Such as: animals' lower limbs and branches.
3, é•‚ :: refers to the jade hollow, not through the air, deep hollow (such as: vases, pen holders, etc.) and shallow hollow (such as: pen wash, ashtray, etc.).
4, line carving: refers to line engraving, silk carving, such as: the character's hair, animal hair and water waves.
5. Yin carving: refers to a method of engraving of the concave part, such as: yin and yang gossip.
6, round carving: refers to the arc-shaped carving, such as: teapots, teacups and spherical jade pieces.
Six, polishing and polishing process 1, grinding:
(1), manual grinding: is semi-mechanized, manually passed through the mill, using various diamond grinding wheel tools, from rough grinding to fine grinding, fine grinding to matt.
(2) Machine grinding: It is fully mechanized, and the processes from rough grinding to fine grinding and fine grinding are completed by vibrating machine using corundum. Generally, the round jade pieces are polished for 3 to 4 days.
2, polishing:
1. Manual polishing: manually through the polishing machine, using a variety of polishing tools and polishing materials to throw light.
2, machine polishing: vibration machine plus polishing materials, the general round carving small jade pieces normally take 2 to 3 days to complete. Manual polishing and polishing are more automatic polishing than the machine. Generally, the polishing time is long and the cost is high, but the effect is also good, retaining the three-dimensional and carved peak style of the engraving ornament.
Seven, decoration 1, decoration of the decoration: with the base is the most important decoration of the decoration, the material and style of the decoration with a lot of seats, well matched to achieve the improvement of art and value.
2, packaging: is the last link, a beautiful jade jade goods, there are good packaging including inner and outer packaging, supporting packaging, both decorative and landscaping effect, as well as protection and transportation functions.
