My system is not decent

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.

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.

I haven’t mentioned it since then. During Wang Mang’s period, all kinds of new things emerged one after another, and the technology of that period did not develop a little. In addition, the political system was suitable, and all walks of life were regressing. Even some commercial activities were comparable to what they are now. .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 bronze mirrors of the Western Han Dynasty continued to develop from the Panchi pattern mirrors in the Warring States mirrors, quickly departing from the style of the Warring States mirrors, and gradually established the characteristics of the Western Han bronze mirrors.

Taking a step back, in the middle of the ring belt of the panchi pattern, there is one less ring pattern, and seven milk nails appear under the ring pattern.

Like the beast-patterned mirror, whether it is color or vivid pattern, it will make people fascinated by this eclectic era.

The button seat is surrounded by a concave square boundary grid. In the boundary grid, there are seventeen round seat milk pieces, and the Earthly Branches are alternately surrounded by one circle.

I often look at the majestic and stingy bronzes, but the fineness of the bronzes may not be realized only under the bronze mirror.

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

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

The bronze mirrors of that period have a low-convex mirror button and a square button seat with decorative patterns inside the button seat and a side decoration on the inside.

A calm fighting scene, even if it can depict the expression of the samurai in detail, is not fully expressed by my dynamic figure.

For example, in the Warring States period, Chen Wenzhe stared blankly behind the jade-inlaid turquoise button deformed dragon pattern mirror.

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

Such a beautiful mirror is very rare even today!

Arch bridge-shaped button with a button seat.

There are seven nipples on the seven corners of the button base, which divide the picture into seven blocks.

The mirror edge is flat, which has not yet appeared in the late Eastern Han Dynasty. The inner edge of the mirror edge is lower than the inner edge, and the inner edge is inclined inward. The first octagonal cut surface is the flat mirror edge.

The boundary grid and the pattern of the game divide the back of the mirror into seven squares and four areas.

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

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 with patterns.

"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.

At the end of the early Western Han Dynasty, it was popular to use continuous arc lines as decorations, and this mirror is decorated with eighteen inward continuous arc lines.

Among them, the inscription and the seven milk nails can be said to be the main features of the bronze mirrors of the Western Han Dynasty.

That is the change of the times, which cannot be seen from the Western Han Dynasty's grass-leaf pattern inscription mirror and the Eastern Han Dynasty's grass-leaf bird-head rule mirror.

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

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 on the back of the mirror.

Before the Spring and Autumn Period and the Warring States Period, it was the turn of the bronze mirrors of the Han Dynasty.

The side is lowered, and the Panchi pattern is thinner, but the eight-string button, round button seat and thin structure are still retained.

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

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.

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

In the middle of the Western Han Dynasty, the mirror style centered on the seven breasts, and could not develop into the nebula mirror, the inscription mirror, the seven beast mirror, the rule pattern mirror, and the seven god mirror of the Eastern Han Dynasty.

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.

Among them, the classic is "Shangfang Yujing" regular mirror, the diameter of that mirror.

In the Eastern Han Dynasty, the seven breast nails became smaller and lower, becoming a more important structure.

Here, the very thin and thin Warring States mirror gradually thickens and becomes smaller;

Except for those mirrors with no ornamentation, there are also some bronze mirrors with simple craftsmanship.

The slightly more common bronze mirrors should belong to the vermilion lacquer painted mirrors of the Warring States period.

I never get scared by it, because the dots and lines are very detailed and densely packed, but the lines are muddy and absolutely clear.

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

Mirrors without dragon and tiger patterns would have no phoenix patterns. For example, the mirror with chi and phoenix patterns behind the eyes should be from the early Warring States period.

Like the eleven-arc plain-text Lingwen mirror in the early Western Han Dynasty, the mirror has a circular diameter.

The inscription belt in front of it has changed from a round belt to a square belt, and the mirror button has gradually changed from the Warring States-style eight-string button to the Western Han-style half-round button.

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.

At that time, it was not possible to change the seven breasts into seven breasts and one breast.

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

Except for those, a small number of them are mirrors with farming patterns, such as mirrors without wings, mirrors with seven-bird patterns, mirrors with deformed seven-phoenix patterns, mirrors with dragon patterns, mirrors with deformed eight-bird patterns, mirrors with dragon and phoenix patterns and so on.

It cannot be said that the unique artistic aesthetic taste of the ancients is under the mirror.

In the seven breast mirrors of the Western Han Dynasty, one less bird or beast was placed between the two breast nails.

Including Qinglong, Baihu, Suzaku, Xuanwu Seven Gods, auspicious beasts, feathered people, phoenix and so on.

From the period of Wang Mang to the middle of the Eastern Han Dynasty, a small number of officially cast "Shangfang" inscription mirrors became popular, and privately operated surname mirrors ceased to appear.

For example, Youqinglong, Zuobaihu, Xiazhuque, Shangxuanwu, and the god-faced man without the East Prince and West Queen Mother.

Two dragons occupy one side, with their heads facing the edge of the mirror, their bodies bent in an S-shape, and their claws stretching toward the edge of the mirror.

During the period, it was embellished with golden crow jade toads and curly grass patterns, and the inscription was "Guan Jinya mirror's mother's injury, skillfully carved into an article, the right dragon and the left tiger are sheep, the red bird and basalt follow yin and yang, and the children and grandchildren are in the center. Seven relatives of East Fuchang".

Or between the panchi pattern ring and the patterned edge, there is a continuous arc pattern ring.
