My system is not decent

Chapter 989
Every historical period has its fixed ornamentation style.

To a certain extent, the jade wares of the Han Dynasty were influenced by the Spring and Autumn Period and the Warring States Period. Some jade decorations of the Spring and Autumn and Warring States Periods have also been handed down, and at the same time, rich and beautiful Han Dynasty decorations have also been produced.

For example, cattail pattern and valley pattern, cattail pattern, a honeycomb-like pattern composed of parallel lines in three directions, was popular from the Warring States period to the middle of the Western Han Dynasty, and was mainly used to decorate jade bi, jade huang, etc.

There are two types of grain patterns, which are composed of grain-like spiral units. One is to draw spiral patterns with thin lines from the inside to the outside on the basis of the cattail pattern, and the other is to create round and independent valley patterns in relief. .

Since so many shapes can be made, it must have a high level of craftsmanship.

The major technical characteristics of jade wares in the Han Dynasty are the characteristics produced by the widespread use of iron tools.

From the perspective of the development history of ironware, iron has high toughness and good forging performance, and can forge tools of various shapes, especially forging small tools for tucking, bumping, hooking, and withdrawing.

It can be said that the widespread use of iron tools had a revolutionary impact on the jade craftsmanship of the Han Dynasty.

It turns out that Chen Wenzhe has not seen the jade wares of the Eastern Han Dynasty, and he has also seen the process of carving them.

However, he has never seen a variety of jade processing processes in the Han Dynasty just by looking back at a jade article.

He knew that the jade ring he recalled this time must not be simple.

Only the royal family can gather so many people and process and carve so many jade stones at the same time.

Also, what he saw this time was the carving site of the Han Dynasty, and ironware was commonly used in it.

Only with the use of iron, can the hollowing process be easily realized. Of course, the cutting process also becomes simple.

During the cutting and molding process in this period, wire saws or straight saws were used, and disc cutters were also used for cutting. Both water and jade sand were added. The tools used depended on the habits of jade workers and the size of jade materials.

The edge of the saw or mound is thin, indicating the sharpness of using a metal tool.

For example, the straight saw marks on jade bi and jade clothes from Han tombs in Mancheng are generally 1 to 1.5 mm wide, and some are only 0.35 mm wide.

Due to the widespread use of iron tools, the production precision of jade pieces has also reached a high level, creating a technical foundation for complex gold and jade inlays.

Of course, these are all common processes, and the one that is a bit difficult must be the ring socket process.

Because Chen Wenzhe saw a process of processing jade chains in the backtracking, one ring is surrounded by another, this is an infinite ring!
This kind of technology is even more superb than the technology of the jade in his hand.

He knows that this is ring carving, which is a complex and superb technique.

It was only in the Han Dynasty that the jade ring processing technology was no longer a problem, so it was often used in vessels and decorative themes.

Seeing this, Chen Wenzhe used an independent inheritance almost without any hesitation.

The main reason is that the hollow dragon and phoenix pattern jade collar in his hand can be said to be the culmination of various top skills of the Han Dynasty.

Through it, Chen Wenzhi can definitely learn many top skills.

Sure enough, with the initiation of independent inheritance, Chen Wenzhe immediately concentrated the top craftsmanship.

From cutting the material to carving out the live ring, to drilling, and then the whole process is presented in front of his eyes.

Chen Wenzhe didn't care about the crowd waiting for him to watch, he was immersed in his study and couldn't extricate himself!

Three people must have my teacher. Some ancient carving techniques, even if many modern people have the right tools, they can't realize it.

Therefore, Chen Wenzhe gained a lot by using independent inheritance on a jade ring from the Han Dynasty.

For example, the drilling process seems to be very simple. The drilling process is simple, but it is really not easy to do it in ancient times without mechanical drills.

The drilling technology of jade wares in the Han Dynasty was very mature, and drill-pipe tools were used in many aspects of jade carving.

The drill bit is generally made of iron, and the inner hole of the relatively slender jade tube can be drilled very straight. However, if the drill is drilled on both sides, sometimes step marks will appear, but the shape of the bell mouth, which is large on the outside and small on the inside, has basically disappeared.

In the Han Dynasty, large-diameter metal pipes were used to polish the outer contour of the jade bi, which made the jade bi round much more rounded, such as the jade unearthed from the tomb of the king of Chu in Shizishan, Pengcheng.

Let's talk about the hollowing out process. After the Spring and Autumn Period, the hollowing out technique was widely used in jade carving.

There was a small climax during the Warring States period, which was mainly used for the engraving of sheet objects, and a small amount of three-dimensional engraving works appeared at the same time, and its craft style has been affecting the Han and Wei Dynasties.

The method of hollowing out is the same as in the previous period. It is mainly to draw the outline first, then perforate the positioning, and then add a metal wire saw to cut it into various shapes, and some holes are used to form a part of the hollowing out.

When using metal wire tools, the wire saw is fixed on both ends of the bow handle, and the bow handle is pulled back and forth, so fine and straight lines are often left on the cutting surface.

Some sword ornaments of the Han Dynasty that were not polished very finely often left fine straight line marks in the holes, and sometimes traces of perforation.

This is generally made by the method of gong bow, which is the result of the use of metal wire, with sharp corners.

Sometimes it is also pulled with a thicker metal bar file, which is also called a "pulling bar".

You must know that these crafts can not only be used on jade wares, but can they also be used on porcelain wares?

When making tires, many porcelains need to be hollowed out, such as the hollowed out salad plate seen earlier.

On top of porcelain, it is easier to make with the top-level hollowing process.

After all, porcelain is not as hard as jade, so it is easier to process.

Of course, the most important craft is definitely the carving craft, which is also the craft that Chen Wenzhe wants to learn the most.

No matter what era, what tools are used, carving is the same routine, but if the tools are not suitable, it will be more difficult to carve, and the carving speed will be much slower.

But no matter how difficult or slow it is, the ancient carving techniques are still useful in modern times and worth learning.

In other words, with the use of modern tools and the carving techniques of the ancients, the artifacts made will be more exquisite.

Of course, when making porcelain, carving is also essential.

Therefore, when learning to carve jade decorations, it is also equivalent to learning porcelain decoration carvings.

In particular, some special tools from the Han Dynasty may not be used now, but the reason is understandable.

For example, if you know how to use a gyro to carve some exquisite patterns, why not use a hand drill now?

Iron tuo tools in the Han Dynasty have been fully used in all aspects of jade carving, such as single-yin lines, double-yin lines, and bumping ground patterns.

These are still simple. The appearance of iron tuo ware in the Han Dynasty made the decorative processing techniques such as intaglio, relief, openwork and round carving in this period further developed on the basis of inheriting the jade carving technology of the previous generation, especially the round carving jade. Increase, highlighting the shape and beauty of jade.
