How to tell the authenticity of antique bronzes?
How to distinguish the authenticity of antique bronzes 1 from the rust color of bronzes?
After thousands of years, bronzes have been handed down in three ways: buried in the ground, falling into the water and handed down from generation to generation. Experts say:? Bronzes have fallen into the water for thousands of years, green as melon skin and jade; In less than a thousand years, although it is green, it is not as good as jade; The handed down bronzes that have not been buried in water are purple-brown, with vermilion spots and even raised spots. ? Generally speaking, most of the unearthed bronzes have been handed down to this day. Due to the different copper soil and water quality in different places, the rust color of buried bronzes is not the same, such as blue rust, red rust, blue rust and purple embroidery. To get a bronze ware, you must first look at it. If the rust color is integrated with the body, the depth is consistent, solid, uniform, smooth and natural, it is a naturally generated rust color. If the rust color floats on the utensils, it is green but not bright, and the skin is rusty and not moist and dazzling, which is pseudo-rust; At this time, we will do further examination and approval, rub our hands and touch the utensils, smell our hands with our noses, and there will be a copper smell, because there is no copper smell in ancient bronzes of the Millennium; You can also wash the bronzes with hot alkaline water, and the fake rust will fall off. If you can't wash it off, use fire. Or lick bronzes with your tongue. If it is salty, it is also fake rust.
2. The feeling and sound of bronzes
When weighing bronzes by hand, too light or too heavy will attract people's attention. Of course, this is all based on experience. In addition, you can tap the bronze objects with your hands and listen to their sounds, if they are thin and crisp; If the sound is cloudy, send it out? Huh? Voice, you need to be vigilant.
3. Patterns and patterns of bronzes
This is a key point in identifying bronzes. The design of Xia bronze wares is very simple. Bronzes in Shang Dynasty are ornate and complicated, and most of them are covered with flowers. The bronzes of the Western Zhou Dynasty are roughly the same as those of the Shang Dynasty, but they tend to be simple in the later period. Bronzes in the Spring and Autumn Period and the Warring States Period are fresh and lively, full of life breath, while Qin and Han bronzes are practical, with few patterns and not as fine as previous bronzes. In addition, we can also infer and judge from the changes of bronze decorative patterns in different times. As for and, it can be distinguished mainly from its font. Bronzes in Shang dynasty have regular fonts, rich and generous strokes, beautiful and free and easy, and there are many elegant and beautiful waves in the later period; At the beginning of Zhou Dynasty, bronze inscriptions followed the wave body; In the Spring and Autumn Period, there were fat bodies, thin bodies and tadpoles in bronze calligraphy. Where's Dai There are patterns? Bird book? ; The inscriptions on bronze inscriptions in the Warring States period are not elegant, but there are also long and pointed fonts. Hanging and printing? Prototype; The Qin dynasty unified the characters, using the universal seal script. Mastering this, it would be a joke if there was a small seal font on a bronze ware called Three Dynasties. In addition, the identification of bronze antiques can also be judged according to the number and content of inscriptions.
4. Bronze in bronze
It is easier to distinguish it from bronze wares. It is the bottom that looks at bronzes. If it's brass, it's fake. If the soles of your feet have been counterfeited with copper color, you can see their true colors by scrubbing them with hot alkaline water. In addition to remembering the types and names of bronzes, we should also know when bronzes were cast and what style bronzes were cast. For example, the altar is a square container that appears at the end of the country. If it is made by three generations and rusts, it is a fake. Another example is the tripod, which has existed throughout the ages, but if it has a cover and the tripod is short, it is unlikely to be an article of three generations.
Maintenance of antique bronzes Distilled water is needed to clean bronzes.
Bronzes must be washed with distilled water. There is grease on the bronze ware. Distilled water can be heated properly, and utensils can be soaked in soapy water, detergent and other cleaning agents for a period of time before cleaning. It is worth noting that the utensils treated with cleaning agent should be washed with distilled water many times to avoid the influence of acid, alkali and other components in the cleaning agent on the utensils.
The attachments on some bronzes are hard, so it is difficult to wash them off at one time. It is forbidden to forcibly remove them with metal or hard objects when cleaning. Repairers made of bamboo and wood can be peeled off bit by bit. For bronzes with holes or hollows, the gaps between them should be soaked with soft cloth and then gently wiped off. The washed articles should be placed in a cool and dry place and stored after evaporation and drying.
A vacuum cleaner can be used to remove heavy bronze objects.
Clean the dust on the bronze ware with a soft cloth, a soft brush, a soft-wool duster, etc. For large, bulky and irregular bronzes, vacuum cleaners and other machinery can be used for dust removal; For bronzes with hollowed-out structures or gaps, you can also use a high-pressure air pump to blow off dust that is difficult for the vacuum cleaner to absorb.
Washing sodium sesquicarbonate with medicine to wash away bronze disease
We should always observe the changes of bronzes. Once bronze disease is found, it should be dealt with in time. We can use sodium sesquicarbonate (5% sodium carbonate+sodium bicarbonate) to clean them. When you encounter some bronzes with serious corrosion and bronzes mixed with other sundries, you should ask professionals to clean them.
Silicone coating is better than paraffin coating.
The traditional preservation method of cleaning bronzes is to coat them with paraffin wax, but it is easy to accumulate dust and unsightly. In this regard, a layer of silica gel can be coated on the bronze to seal it, which can prevent harmful gases and dust more effectively.
The collection value of bronzes Bronzes is known as? The heavy weapon of the country? However, due to legal and market reasons, the investment in bronze collection is not as popular as jade, porcelain, calligraphy and painting. Liang, vice chairman of the Guangdong Collectors Association and director of the Bronze Professional Committee of the Guangdong Tibetan Association, believes that the bronze market is not as eager for quick success as other collection markets, and collecting bronzes can calm down and enjoy the pure fun brought by collection.
Liang loves the profound cultural connotation of bronzes. He has been collecting bronzes since the early 1990s, and now it has reached a certain scale. For Liang, the profound historical and cultural value of bronzes and the vicissitudes of thousands of years are the places that attract him.
Bronzes have profound historical and cultural values, but there are not many collectors.
Although bronzes have a very long history and are often selected as the record carrier of major events in history, which has profound historical value and cultural significance, there are not many people who collect bronzes today.
Liang said to him:? The current collection market is similar to the investment market, and everyone likes to collect popular collections. Collections that can quickly change hands and earn the difference from them are especially popular. However, for some reasons, bronzes are not so easy to circulate in the collection market, so bronzes are not a popular collection category. There are not many people who collect bronzes in Guangdong, and only a few dozen people have a systematic collection. ?
Liang began to collect bronzes very early, which is related to his experience. ? Few people in our south collect bronzes, and everyone prefers things after the Ming and Qing Dynasties. Compared with the south, the atmosphere of collecting bronzes in the north is relatively rich. ? Because of his working relationship, Liang began to work in the north in the 1990s, which enabled him to get to know the northern collection circle and gradually come into contact with bronzes.
? After contact with bronzes, it is difficult to like other kinds of collections, and even if you like them, you can't reach the degree of infatuation. ? Liang said to him:? Generally, bronzes are before the Han Dynasty, so the heavy feeling accumulated in such a long history is different from the collection with a history of only two or three hundred years. ?
The bronze collection market has not warmed up, which is an alternative.
Liang said that due to domestic laws, the auction and trading of bronzes are limited to well-circulated collections, so the number of bronzes circulating in China is small, and the bronze collection market has not warmed up as other collection markets in recent years. On the contrary, the market price of bronzes is even lower than ten years ago.
? Now the price of bronzes is even lower than when I collected them in the early 1990s. This is an alternative in the collection market, but it does not mean that bronzes have no collection value. In fact, bronzes are very popular in foreign markets, and many international museums are proud of collecting Chinese bronzes. ? In Liang's view, China's bronzes are the representatives of the most brilliant stage in human history. The civilization that emerged in that period may still benefit from it until now and cannot be cracked. ? I ching was written at that time. Can we say that we can fully explain the meaning of the Book of Changes now? We can learn about the culture of that period through bronzes. ?
Bronze itself has profound cultural and historical connotations, and the market is relatively calm. Liang believes that bronzes are more suitable for collectors to collect. ? When I first chose bronzes, I thought the collection of bronzes was relatively simple, so I didn't have to consider too many market factors. It is a very energy-consuming thing to think about the ups and downs of the market all day, which market will heat up and which market will heat up in the future. I already have a job myself, and collecting should be a pleasure. I should not worry about market trends and prices, but concentrate on collection and appreciation, which is more in line with the essence of collection itself. ? Liang said to him:? If you always consider the preferences of the market, collect jade articles this year, calligraphy and painting next year, and mahogany furniture the year after. I can't play anything well at this speed. Maybe in the end, I bought here and sold there and made some money, but I didn't really stay. I have a certain amount of collection. ?
Where are the bronzes? Flower in the wall smells good outside the wall? The dilemma of
As Liang said, foreign museums and collectors like Chinese bronzes very much. In contrast, the enthusiasm of domestic collectors for bronze collection is unmatched by other kinds. There is a view that bronzes are in? Flower in the wall smells good outside the wall? The dilemma is that foreign collectors like Chinese bronzes, while domestic collectors don't; Crucially, for various reasons, many excellent bronzes have been lost abroad.
