My system is not decent

Chapter 1819 Shangfang Yujing is big without injury, and it is skillfully carved into an article

Tire hair rust is the rust layer that corrodes from the inside to the outside of ancient coins. In this case, the body of the coin becomes thicker, and most of them are kept in closed storage without rust removal.

Gilt and silver mirrors generally do not need to be derusted. In a few cases, if it is necessary to derust, they can be soaked in 15.00% glacial acetic acid solution or [-]% sulfuric acid solution.

If fetal hair rust is found on the gilt silver mirror, you can use a brush dipped in 5.00% trimethyl resin to apply two or three layers, which will play a sealing role.

There are many ways to remove rust. If the rust is relatively light, it can be properly heated, and the rust can be peeled off by using the principle of thermal expansion and contraction.

Glacial acetic acid immersion and heating methods cannot be used for severely corroded iron coins.

For individual iron mirrors that require special rust removal, the electrochemical reduction method of zinc and caustic soda and the electrolysis of caustic soda can be used.

For more expensive iron mirrors, the hydrogen furnace reduction method can be used.

While looking at the bronze mirrors in the museum, Chen Wenzhe learned useful techniques from them.

There are still quite a few bronze mirrors in the Spring and Autumn and Warring States Periods. Apart from those more classic ones, there are also some more in number.

Of course, this number is relatively large.

For example, in the Warring States period, the mirror with moiré ground and arc pattern, the mirror button is a three-string button, which is the main button type in the Warring States period.

The circular button base is decorated with a non-grained circular belt around the button base, and the ordinary mirror edge and the circular belt of the button base are decorated with a non-grained continuous arc-shaped belt.

The ground pattern of the main pattern is decorated with cloud patterns, which are commonly seen on jade wares during the Warring States Period.

There is also a composite mirror with double tigers in the Warring States period. This round composite bronze mirror in front of you has double dragons carved on the back of the mirror.

The two dragons occupy one side, with their heads facing the edge of the mirror, their bodies curved in a slightly S-shape, and their claws stretching toward the edge of the mirror.

The dragon's body and feet are thick and thick, covered with cloud patterns and other decorations, and its posture is vivid.

The edge of the mirror is wide and flat, and the outer circle is decorated with cloud and thunder patterns.Composite traces can be seen between the frieze and the mirror rim.

Arched bridge-shaped button, without button seat.

There are mirrors with dragon and tiger patterns, and there are also phoenix patterns. For example, the mirror with continuous arcs and phoenix patterns in front of you should be something from the late Warring States period.

The slightly special bronze mirror should belong to the vermilion lacquer painted mirror of the Warring States Period.

In addition to these, most of them are mirrors with farming patterns, including feather wing mirrors, four bird pattern mirrors, deformed four phoenix pattern mirrors, dragon pattern mirrors, deformed three bird pattern mirrors, dragon and phoenix pattern mirrors and so on.

These bronze mirrors look at the details, even with the help of the macro function of the lens.

Sometimes I am frightened by it, because the dots and lines are very detailed and dense, but the lines are clear and unambiguous.

I often look at the majestic and majestic bronzes, but the fineness of the bronzes may only be experienced on the bronze mirror.

Like the beast pattern mirror, no matter the color or vivid pattern, it will make people fascinated by that eclectic era.

In a fierce animal fighting scene, even if the expression of the samurai cannot be described in detail, it has been fully expressed through his dynamic figure.

It can be said that the unique artistic aesthetic taste of the ancients is reflected in the mirror.

In addition to these mirrors with only ornamentation, there are also some bronze mirrors with complicated craftsmanship.

For example, Chen Wenzhe was dumbfounded in front of the jade-inlaid turquoise button deformed dragon pattern mirror in the Warring States period.

Such a beautiful mirror is very rare even today!
After the Spring and Autumn Period and the Warring States Period, it was the turn of the bronze mirrors of the Han Dynasty.

For example, the 18.4-arc Plain Dilingwen Mirror in the early Western Han Dynasty, this mirror has a diameter of 341cm and a weight of [-]g.

It is a three-string button, with rhombus patterns arranged alternately on the mirror, and eleven continuous arc patterns facing inward on the mirror edge.

During the Western Han Dynasty, the continuous arc-shaped ring belt gradually replaced the Warring States mirror-style border and became the continuous arc-pattern border, which was an important category of Western Han bronze mirrors.

The bronze mirrors of the Western Han Dynasty continued to develop from the Panchi pattern mirrors in the Warring States mirrors, slowly departing from the style of the Warring States mirrors, and gradually established the characteristics of the Western Han bronze mirrors.

Among them, the inscriptions and four breast nails can be said to be the main features of the bronze mirrors of the Western Han Dynasty.

In addition, the very thin and thin Warring States mirrors gradually thickened and enlarged;

The sides are heightened, and the panchi pattern is thinner, but the three-string button, round button seat and thin structure are still retained.

Further, in the middle of the ring belt of the panchi pattern, a ring pattern is added, and four breast nails appear on the ring pattern.

Or between the panchi-shaped ring and the edge without patterns, a continuous arc-shaped ring appears.

On the other hand, bronze mirrors from the Western Han Dynasty can be seen to add a ring of inscriptions to the Warring States-style round button base without patterns.

Later, the circle of inscription belts changed from a round belt to a square belt, and the mirror buttons gradually changed from the three-stringed buttons of the Warring States style to the semi-circular buttons of the Western Han Dynasty.

Among them, the classic is the inscription mirror, or the nebula bronze mirror.

In the mid-Western Han Dynasty, the mirror style centered on the four breasts, and could be developed into the nebula mirror, the inscription mirror, the four beast mirror, the rule pattern mirror and the four god mirror of the Eastern Han Dynasty.

At this time, the four breasts can be transformed into five breasts and seven breasts.

Because Taoism was prevalent in the Eastern Han Dynasty, many concepts of Taoism appeared in the mirrors and pottery of the Eastern Han Dynasty.

For example, the left green dragon, the right white tiger, the upper rose bird, the lower Xuanwu, the god-faced man and the east prince and west queen mother.

In the four breast mirrors of the Western Han Dynasty, an extra bird or beast was placed between the two breast nails.

In the Eastern Han Dynasty, the four breast nails were enlarged and elevated, becoming a more important structure.

By the end of the Eastern Han Dynasty, the pattern became more three-dimensional, so the figures, chariots and horses were obviously protruding, and even the mirror buttons were more protruding.

This is a change of time, which can be seen from the grass-leaf inscription mirrors of the Western Han Dynasty and the grass-leaf bird-head mirrors of the Eastern Han Dynasty.

The bronze mirrors of this period have high convex mirror buttons, a square button seat, no decoration inside the button seat, and a strip on the outside.

There are four breast nails at the four corners of the button base, which divide the picture into four blocks.

In the space between the breast nails and the breast nails, two birds and grass leaves can be seen, and they form a group of two, with the two birds sideways and facing the back.

The edge of the mirror is flat, which has not yet appeared in the late Eastern Han Dynasty. The outer edge of the mirror edge is higher than the inner edge, and the outer edge is inclined outward, finally forming an uneven mirror edge with a triangular cut surface.

In the late Western Han Dynasty, it became popular to use continuous arc lines as decorations, and this mirror is decorated with sixteen inward continuous arc lines.

Among them, the classic one is "Shangfang Royal Mirror", a regular mirror with a diameter of 16.1cm.

It is a round, round button with a persimmon-shaped button seat.

The concave square boundary grid around the button base is surrounded by [-] round bases and earthly branch characters in the grid.

The boundary grid and the bureau pattern divide the back of the mirror into four directions and eight areas.

It is equipped with eight round seat milk pieces and auspicious animal decorations.

Including Qinglong, Baihu, Suzaku, Xuanwu four gods and auspicious beasts, feathered people, phoenix and so on.

During the period, it was embellished with golden crow jade toad and curly grass decorations. The inscription is "Shangfang's imperial mirror is big without injury, and it is skillfully carved into an article. The left dragon and the right tiger are not sheep, the red bird and basalt follow the yin and yang, and the children and grandchildren are in the center. Chang Bao Er Pro East Fuchang".

"Shangfang Royal Mirror" regular mirror, "Shangfang", is the official signature, set up by the Qin Dynasty, in charge of casting weapons, bronze mirrors and some ornamental objects used by the royal family.

From the period of Wang Mang to the mid-Eastern Han Dynasty, a large number of officially cast "Shangfang" inscription mirrors became popular, and privately operated surname mirrors began to appear.

As mentioned before, various new things emerged one after another during Wang Mang's period. During this period, science and technology also developed greatly. In addition, the political system was suitable, and all walks of life were making progress. Even some commercial activities were comparable to today's.
