At present, the collection of porcelain in the Ming and Qing Dynasties has intensified, especially in the Qing Dynasty. At the auction, a fine kiln boutique was lifted to hundreds of thousands and millions of yuan. However, behind the excitement, there is a serious problem hidden in it, that is, imitations and counterfeits are confusing.

In response to the collection of porcelain in the Ming and Qing Dynasties, Jin Baotang experts have explained this problem to many Tibetan friends. According to experts, the reason why the Ming and Qing porcelain collections are so hot is mainly due to two reasons:

First, the Ming and Qing porcelain, scarce, high price, sought after. The Ming and Qing dynasties are the glorious period in the history of Chinese ceramics development. The porcelain technology has been continuously innovated and developed. The firing of color glaze porcelain has reached the realm of perfection, ending the blue and white monochrome glaze before the Yuan Dynasty. In the situation, the colorful porcelain represented by blue-and-white porcelain flourished. At the same time, the porcelain in this period is rich in variety, and the ornamentation is eclectic and artistic. For a long time, Ming and Qing porcelain is the target pursued by collectors and the darling of the auction.

Second, the Ming and Qing porcelain, free to buy and sell, high value-added. Most of the existing Ming and Qing porcelains are handed down to the world. They do not touch the legal bottom line in exchanges and transactions. They can be bought and sold freely and have a wide collection base. At the same time, as a non-renewable resource, its value preservation and value-added are very high, and it has become an important direction for people's investment.

Greedy "missing" for taboos

Jinbaotang experts reminded that with the continuous warming of the collection of porcelain in the Ming and Qing Dynasties, the collection team has grown rapidly, and the Ming and Qing porcelains have already been in short supply in the collection market. The threshold of porcelain collection in the Ming and Qing Dynasties is getting higher and higher. If there is no certain eyesight, there is no considerable financial resources. It is very risky to collect it blindly. Because there is no fool in the antiques, who doesn't want to make money, the ending of "missing" is often deceived.

Do a good job of collecting and keep learning

According to Jinbaotang experts, there are more and more people who are engaged in the collection of porcelain in the Ming and Qing Dynasties. The first thing to do when entering the trip is to learn. Not only must we look at a large number of related books, but we must also pay attention to it everywhere. We must observe a large number of real and fake objects in the museum and the market, and try to communicate with friends in the circle as much as possible. These all require a long process, and eyesight and market experience are practiced in this process. The more you look at it, the more you know whether your collection is true and whether it is good enough. Antiques are an experience. It takes time to accumulate and is based on knowledge.

Looking for the teacher to listen to Tibetan friends

In the process of learning the appreciation of porcelain collections in the Ming and Qing Dynasties, it is important to choose a special item and find a good teacher in the line. This teacher not only wants to have good eyesight, but also is honest and has a good reputation in the industry. He not only teaches you to identify the collection, but also teaches you to know the industry and the market. Choose a teacher, it is best to find "one fine", not "road pass", do not go to those who can only talk about it. Engage in collecting, but also learning, don't be afraid to be fooled, and don't be afraid to be jokes by others. One of the most crucial ones is to be able to listen to the negative opinions of experts or Tibetan friends on your collection, and seriously reflect on them. Only then can we grow. In the collection circle, if you want to hear a truth, a pertinent word, or a negative word, it is very rare and must be cherished. (Jinbaotang)

Steel Bolt

Bolt is a kind of fastener which consists of head and screw (cylindrical body with external thread) . It should be used with nut for fastening two parts with through hole, an Anchorage Assembly that anchors the connector to a hardened concrete substrate.

Because the bolt is also a kind of railway accessories, railway accessories is a part of the railway line, here refers to the track including steel rails, sleepers, connecting parts, bed, anti-climbing equipment, rail support and turnout, etc. . As a whole engineering structure, the track laid on the roadbed plays a guiding role in train operation and bears the huge pressure of the locomotive and its load directly. Under the dynamic action of the train, its components must have enough strength and stability to ensure the train to run safely, smoothly and continuously in accordance with the prescribed maximum speed. Main classifications are general and hinged according to the manner in which the joints are loaded. The ordinary main load bearing axial force, but also can bear the lateral load demand is not high. Bolts for reaming holes shall be fitted to the hole dimensions and shall be used when subjected to lateral forces. According to the shape of the head is divided into hexagon head, round head, square head, heavy head and so on. The hexagonal head is the most commonly used. The countersunk head is usually used where a smooth, raised surface is required after joining, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be greater, but the size is very large. In addition, in order to meet the needs of locking after installation, there are holes in the head, rod hole, these holes can make the bolt vibration not loose. Some bolts do not thread bare rod to do fine, called fine waist bolt. This bolt is advantageous to the connection subjected to variable forces. There are special high-strength bolts on the steel structure, the head will be bigger and the size will change. Also has the special use: T-slot Bolt, the machine tool fixture with the most, special shape, the head of both sides to be cut off. Anchor Bolts, used for machine and ground connection and fixation, come in a variety of shapes. U-BOLTS, as described above. Wait a minute. There are special welding stud, one end has a thread, one end is not, can be welded on the parts, the other side directly screw nut. The U-BOLT is a non-standard part. It is also called U-bolt because of its u-shaped shape. The two ends of the bolt can be combined with a nut. It is mainly used to fix the leaf spring of a tubular object such as a water pipe or a piece of material such as a car, it is called a riding bolt because it fastens the object in the same way that a man rides a horse.
