Buy jade carving is to see the material or to see the artistic value
Is buying a work looking at materials or looking at artistic value? This is an old question that never gets tired of. Especially like contemporary jade carving, jade, Tianhuang, purple sand, mahogany and other varieties, made with rare materials, in the first two years of the art market is hot, but often because the price of the material itself is expensive, so that the market participants There is an illusion that it seems that those varieties will only rise and fall forever, and many people therefore dismiss the old problems mentioned above.
However, once the market conditions have been adjusted, the old problems that have been left unchecked by many people have revealed awkward fangs, and you are not allowed to have any ambiguity and embarrassment. After all, art depends on its artistic value, and it is this value that determines its collection value and allows it to preserve and increase its value. Especially when the market is in turmoil, the artistic value guarantees that the works of art can stand out and remain strong. Although the material itself is an indispensable part of the art work, its price rises and falls follows another set of laws, which is more related to the economic situation, the degree of inflation and the precious metal market, and its cycle of ups and downs is hard to resist. Therefore, when the material market is adjusted, the value of those works that lack artistic value will fall.
The most recent example is the contemporary jade carving. The author noticed that this year's spring shoot finale Xiqiao Printing Agency auction company's jade carving special, the total turnover decreased significantly. After some investigation and analysis, the author found that the supply and demand relationship of Hetian jade market has undergone significant changes: on the one hand, some of the jade carving master's studios push the works to the auction at a lower commission price, and on the other hand, the buyers. The group held a wait-and-see attitude towards the market due to market adjustments. As a result, the oversupply of auction items on the auction floor caused the price line of the jade carving works to be hit in this spring.

Behind the above situation, the price trend of Hetian jade as a material has been falling. The industry usually divides Hetian jade into three grades. According to the data released by the Xinjiang Hetian jade market information alliance, the price performance of these three grades of Hetian jade is different, but they are falling together: forming between the lowest price and the highest price. In the price range, the lowest price of the top-grade collector-grade raw materials remains unchanged, and the highest price falls by 10%; the high-quality processing raw materials at the intermediate level, the lowest price falls by 10%, the highest price falls by 15%-20%; For processing materials, the lowest price fell 10% and the highest price fell 20%. The explanation of the experts in the industry is: In 2014, the price of the mining source of Hetian jade raw material has fallen to the cost price, which caused the lowest price in the price range of Hetian jade transaction to have no downside; while the sales price of Hetian jade sold in the terminal market is The decline has mostly been related to the increased pressure on the operating costs of the Hetian jade device sales market and the strong demand for funds to be returned.
Why are some of the jade carving master's studios willing to auction auctions of jade carvings at low prices this spring? It is not difficult to find the answer to the above market background. The rise in material prices is good for short-term studios with a certain amount of inventory, but it is disadvantageous in the long run because they will have to invest more money and energy in materials in order to maintain operations. This just shows that the market price of Hetian jade raw materials has risen sharply, which is not conducive to the long-term development of the market. Not only does it make many buyers feel that this market is too high to climb, and even those studios suffer.
When materials no longer plague studios and their buyers, people will naturally focus on the artistic value of jade carvings. It can be seen that the price of jade materials has been lower in the second half of last year, which is a long-term positive for the jade carving market: it can not only lower the cost of jade carving works, but also help attract more buyers. No wonder those studios will be willing to lower the price in this spring auction. The fall in the market price of Hetian jade material, we may wish to see it as a kind of return, which not only means that it returns to its normal state, but also means that its downstream jade carving market has begun to return to normal, which means that market sentiment will gather again and the market will start again.
A set screw, also known as a blind screw or a grub screw, is a type of screw generally used as a detent to secure an object within or against another object,[1] usually without using a nut (see Bolts compared with Screws). The most common examples are securing a pulley or gear to a shaft. Set screws are usually headless, meaning that the screw is fully threaded and has no head projecting past the thread's major diameter. If a set screw does have a head,[clarification needed] the thread will extend all the way to the head (whereas a bolt might have an unthreaded shank between the head and thread). A set screw is almost always driven with an internal-wrenching drive, such as a hex socket (Allen), star (Torx), square socket (Robertson), or a slot. The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object. It exerts compressional or clamping force through the bottom tip that projects through the hole.
Set screws appear with a variety of tip (point) types. The different shaped tips have different properties that engineers can utilize. If an engineer were to use a detent to ensure proper nesting of the screw, they might choose to use a cone point type of screw. One might often need to use a flat point when the screw must press perfectly flat against a surface. The most common type is the cup point. This type works well because the surface is rounded so that a small surface area is in contact, but it does not have extremely high stress at one point like that of a cone point. Durability studies show that the cup point offers superior resistance to wear while maintaining a strong grip.[3] Knurled cup points offer the added advantage of a locking action (similar to that of a serrated lock washer) that prevents the screws from working loose in high-vibration applications.[4]
Common points include the following:
Flat point
Domed point
Cone point
Cup point
Extended point (pilot point, dog point)
Knurled cup point
set screw, dog point set screw, cup point set screw, cone point set screw
