My system is not decent

The shape of gold hollow jewelry is more complicated and changeable, and the style is more fashionable and beautiful.

Compared with other shapes, hollow gold looks better, so it is also a more popular craft.

At the same time, because the hollowing out process is relatively complicated, the general process cost will be higher.

But such a process is not perfect.

Although the hollowing process is beautiful, it is also relatively easy to deform.

Because the gold after hollowing out is all filaments, compared with the whole piece of gold, the load-bearing capacity is much worse.

Therefore, under the action of external force, it is relatively easy to deform.

Therefore, you need to be extra careful when wearing it to avoid impact.

In addition, gold is relatively oil-friendly and ash-friendly, and the hollowed-out style creates a lot of hiding space for these putties, which is easy to form hygienic dead ends and is difficult to clean.

Everything has two sides, there is a good side, and there must be a bad side.

The same is true for gold hollow jewelry, and there is one more thing to pay special attention to in this regard.

The process of hollowing out gold jewelry is complicated, and the manual cost is relatively high, so this kind of exquisite gold jewelry will not be more expensive when it is recycled.

This is mainly because hollowed-out gold jewelry looks better and may be more expensive when sold.

But when recycling, we only calculate the price of raw materials, not the process cost of gold jewelry.

Therefore, the price of hollow gold jewelry is similar to that of other gold jewelry.

Speaking of this, there is another process that needs to be paid attention to, which is the hollow and openwork process.

Especially the air-through technique, which is used a lot on ancient bronzes.

In the Bronze Age, the craftsmanship of the air-permeable bronzes is still very good.

The development of my country's bronze technology was mainly in the Spring and Autumn Period and the Warring States Period.

Among them, the air-permeable bronze ware was even more characteristic at that time.

Permeable bronze mainly refers to the structural characteristics of bronze. The beginning of permeable bronze in our country should be in the middle of the Western Zhou Dynasty.

Then it was developed in the Spring and Autumn Period and the Warring States Period, and its most prosperous period was in the middle and late period.

The permeable bronze culture is similar to the traditional bronze culture, mainly because its structure is different from the soft film of some castings.

In the casting of hollow bronze, there will be many small holes or interwoven copper stalks.

These are the characteristics of the air-permeable bronze ware, but due to too much bending during the casting process, the air-permeable bronze ware is not smooth.

Before the Spring and Autumn Period and the Warring States Period, especially in the Xia and Shang dynasties, bronze was already very prosperous.

Bronze is a symbol of royal power, which has changed the previous situation of rough workmanship and few patterns.

In some common ceremonial musical instruments, weapons, miscellaneous utensils, etc., a large number of animal face patterns and cicada patterns are used.

In the Spring and Autumn Period and the Warring States Period, it was the heyday of the Bronze Age.

Among them, air-permeable bronzes appeared, and the workmanship was even more exquisite and complex. It was also during this period that a large number of famous swords appeared.

In the development of bronze ware, many items are cast in bronze.

For example: ritual musical instruments, wine utensils, weapons, food utensils and other utensils.

A distinctive bronze casting is a work of art.

This also reflects the culture and technology of the time.

There are many styles in bronze ware, such as: coiled dragon pattern, coiled snake pattern, coiled snake pattern, hollowed out and so on.

These are distinguished according to the structure and appearance of the bronzes.

Among them, the hollowing out is mainly in the carving of bronze wares, while the other lines are mainly the distribution of lines on the bronze.

Hollow bronze ware mainly focuses on the "empty" feeling of bronze.

It is the space on the bronze vessel, which is not a whole.

Emphasis on the internal structure of bronze ware, so the difference between hollow bronze ware and other bronze ware is the "emptiness" on the vessel, showing the discontinuity of the vessel's structure.

On the whole of the hollow bronze ware, the parting surface is basically in the form of a flat parting surface at the beginning, and finally extends to the combination of multiple planes and the parting surface.

Take Zenghou Yizun plate as an example, its handicap is a relatively regular cylindrical shape.

The parting surfaces on the top are all outwardly extending, and the ones attached to the bronze are all s-shaped parting surfaces.

Whether it is the upper cylinder or the decoration of the cylinder, it is a continuous parting surface.

And there are edges and corners between each parting surface and the connection.

In lost wax casting, many casters use soft film.

The casting of ceramics uses hard molds, and the difference between the two after casting is obvious in appearance.

But why some people still can't tell the difference between the lost wax casting of bronze ware and the hollow bronze ware, mainly because they don't know the appearance of the hollow bronze ware very well.

Most of the decorations between the air-permeable bronzes are interwoven with several layers.

Several layers are interlaced with each other, presenting a three-dimensional form.

However, the joints in the connection between the decorations are supported by many supports, otherwise they will not be strong enough.

For example, in the internal structure of the moiré, different levels of runners are designed by using the combination of the outer mold and the upper mold of the core to make such a hollow combination stronger.

During the Spring and Autumn Period and the Warring States Period, winding three-dimensional hollow bronzes with hollow patterns appeared.

These are incomparable to the lost wax. Most of the decorations in the hollow bronzes are regular and intertwined shapes.

Its workmanship is very complicated, there can be no mistakes, and it is necessary to ensure that the connection between each decoration is firm and flawless.

Therefore, the ornamentation of the hollow bronzes is also very complex and diverse.

In the hollow bronze, there will be many s-shaped decorations, and there will be many sunken circle patterns on the decorations.

For example, if you zoom in on the surface of the cylinder above Zenghou Yizun, you can see more circle patterns.

The circular patterns like this are the characteristics of the air-permeable bronzes.

And there are many bronze decorations, copper bans, copper ampoules, copper smokers, etc. will have their own characteristics.

Generally speaking, in this kind of circle pattern, there will be a copper stalk.

These copper stalks are all left for determining the position of each design in the design of the ornamentation.

The circle pattern of this kind of air-permeable bronze ware all has such craft characteristics.

For example, among the air-permeable bronze wares, there is a well-known deformed coil snake pattern mirror.

Among them, the circle pattern on the bronze ware all appeared in response to the technology that needs to decorate the surface.

Its main purpose is to position each design in the ornamentation.

The main reason is that during the construction of the hollow bronzes, many decorations need to be connected with each other.

Otherwise, the artwork is not exquisite enough, and copper liquid is needed to fill the shape in the sprue inside.

Make the internal structure of the hollow bronze ware more solid, and image the external beauty.
