Chapter 1810: Hollow Bronze Stem, Symbol of Royal Power
The shape of gold hollow jewelry is more complex 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 process is relatively complex, the general process cost will be higher.
But this kind of craftsmanship is not perfect.
Although the hollowing process looks good, it is also relatively easy to deform.
Because the gold after hollowing out is in the shape of filaments, its load-bearing capacity is much lower than that of a solid piece of gold.
Therefore, it is relatively easy to deform under the influence of external force.
Therefore, you need to be extra careful when wearing it to avoid impact.
In addition, gold is relatively oil-friendly and dust-friendly, and the hollow style creates a lot of hiding space for the putty, which can easily form hygienic dead corners and be difficult to clean.
Everything has two sides. There is a good side and there is definitely a bad side.
The same is true for gold hollow jewelry. There is one more thing that needs special attention in this aspect.
The craftsmanship of hollow gold jewelry is complicated, and the additional labor costs are relatively high, so this kind of exquisite gold jewelry will not be more expensive when recycled.
This is mainly because hollow gold jewelry is more beautiful and may cost more when sold.
But when recycling, we will only calculate the price of raw materials, not the process cost of gold jewelry.
Therefore, the price of recycling hollow gold jewelry is similar to that of other gold jewelry.
Having said that, there is another craft that needs to be paid attention to, which is the openwork and openwork craftsmanship.
Especially the hollow craft, which was used a lot on ancient bronzes.
During the Bronze Age, the craftsmanship of hollow bronze vessels was still very distinctive.
The development of bronze craftsmanship in my country mainly occurred in the Spring and Autumn Period and the Warring States Period.
Among them, hollow bronze wares were a special feature of that time.
Hollow bronze mainly refers to the structural characteristics of bronze. The beginning of hollow bronze in our country should be in the middle of the Western Zhou Dynasty.
Then it was developed during the Spring and Autumn Period and the Warring States Period, and it was most prosperous in the middle and late periods.
The hollow 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 intertwined copper stems.
These are all characteristics of hollow bronze wares, but due to too many bends during the casting process, the hollow bronze wares are not smooth.
Before the Spring and Autumn Period and the Warring States Period, especially in the two dynasties of Xia and Shang, bronze was already very prosperous.
Bronze is a symbol of royal power, which has changed the previous situation of rough workmanship and few patterns.
Animal face patterns and cicada patterns are widely used in some common ritual instruments, weapons, miscellaneous utensils, etc.
During the Spring and Autumn Period and the Warring States Period, it was the heyday of the Bronze Age.
Among them, hollow bronze wares 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 were cast in bronze.
For example: ritual instruments, wine sets, 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 bronzes, such as: dragon pattern, cockroach pattern, snake pattern, hollow, etc.
These are distinguished based on the structure and appearance of bronze vessels.
Among them, hollowing is mainly used in bronze carvings, while other patterns are mainly in the distribution of lines on bronze.
Hollow bronze wares mainly focus on the "empty" feeling of bronze.
It's just that the space on the bronze vessel is not a whole.
The internal structure of the bronze is emphasized, so the difference between hollow bronze and other bronzes is the "emptiness" on the vessel, which shows the structural discontinuity of the vessel.
On the whole, the hollow bronze wares are basically in the form of parting surfaces, starting from the flat parting surface form, and finally extending to the combination of multiple planes and parting surfaces.
Take the Yizun plate of Marquis Zeng as an example. Its opening is a relatively regular cylindrical shape.
The ones above are all parting surfaces extending outward, and the ones attached to the bronze are all S-shaped parting surfaces.
Whether it is the column above or the decoration of the column, they are all continuous parting surfaces.
And there are edges and corners between each parting surface and the connecting surfaces.
In lost wax casting, many casters use soft film.
Ceramics are cast using hard molds, and the difference between the two after casting is obvious in appearance.
But why are there still people who can't tell the difference between lost-wax casting of bronzes and hollow bronzes? The main reason is that they don't fully understand the appearance of hollow bronzes.
The patterns between the hollow bronzes are mostly intertwined and have several layers.
Several layers are interlaced with each other, presenting a three-dimensional form.
However, the junctions between the decorations are supported by many supports, otherwise they will not be strong enough.
During the Spring and Autumn Period and the Warring States Period, winding three-dimensional hollow bronze wares with hollow patterns appeared.
These are incomparable to lost wax. Most of the decorations on hollow bronze vessels have regular and intertwined shapes.
The workmanship is very complex, and there must be no mistakes. It is also necessary to ensure that the connections between each pattern are firm and flawless.
Therefore, the decoration on hollow bronze vessels is also very complex and diverse.
In hollow bronze vessels, there will be many S-shaped decorations, and there will be many sunken circle patterns on the decorations.
For example, if you zoom in, you can see more circular patterns on the edge of the cylinder on which Zeng Hou Yizun is placed.
Circular patterns like this are the characteristics of hollow bronze ware.
And there are many bronze decorations, copper bans, copper pots, copper fumigators, etc. that all have their own characteristics.
Generally speaking, in this kind of circle pattern, there will be a copper stem.
These copper stems were left behind to determine the position of each design when designing the pattern.
The circular patterns on hollow bronze vessels like this all have such craftsmanship characteristics.
For example, among the hollow bronze ware, the more famous deformed snake-patterned jian.
Among them, the circular patterns on the bronzes all appeared in response to the need for surface decoration techniques.
Its main purpose is to position each design in the decoration.
The main reason is that during the construction process of hollow bronze vessels, many patterns need to be connected to each other.
Otherwise, the artwork will not be beautiful enough, and molten copper is needed to fill the shape in the sprue inside.
Make the internal structure of the hollow bronze more solid and the image externally beautiful.
