How to identify the seed material is a university question, how can the primary jade friends quickly grasp the doorway of the seed material? Let's take a look at the small series of China Jewelry Merchants Network !
Color discrimination
Color system identification: Hetian jade seed material is held in the hand, in normal light or under the sun, the far-sighted, near-looking color system is unchanged, belonging to a warm, soft white. The mountain material, in normal light or under the sun, looks white when it is normal, and looks a little blue when looking far, especially when it is put together with the sample of the material. When comparing this method, look at it, look far, It can be seen that the difference, because this visual method is tried and tested, is a good way to distinguish jade. No matter how white the jade looks white, the jade belt that does not belong to Hetian Tsai will look blue or cyan.
Identify from the crack of the seed jade
It is recognized from the cracks of the seed jade: everyone knows that the skin color is one of the important characteristics of the seed jade. Since ancient times, the skin of the Tianzi jade has been precious tiger skin seeds, buckskin seeds and autumn pear seeds, which are very difficult. However, the probability of naturally forming skin color is less than one tenth. The jade that is close and pure in jade quality will not form skin color. Many seed jade have no skin. Many mountain materials have been polished and fake skins have been able to achieve chaos. The point, how to identify its authenticity? At this time, the crack of the seed jade has become an important identification mark. Seed jade in the riverbed after thousands of years of scouring collision, more or less will have a little crack, cracks often invade the skin color, these cracks as long as they do not affect the main body are good. The polished seed and roller material types are relatively perfect, rarely cracked, and it can be seen that there are multiple initial polished sections, so the crack is also a sign to distinguish the true seed jade!
Look at the skin and water infestation
Water-grass infestation, some of the abundance of epidermis is water-grass-like infection, which can be said to be evidence of iron in the feed, because this grass-like infection is not formed by short-time artificial dyeing, but thousands or even tens of thousands of years of ore. The result of material infestation. The long-term contact between the metal salt and the sapphire, the material exchange between the shallow fissures and the fibrous crystals of the jadeite on both sides, forming such a burr-like watery grass-like infection, which is the mark of time, and this infection is lurking. A little bit below the jade on both sides of the crack.
Start with the skin color of the seed material
The true seed material is washed in the river water for thousands of years, and it is naturally affected. It only enters the color in the soft and soft place, and the color is deeper in the cracked place. This skin color is quite natural, that is, the living skin that everyone talks about. Its color is immersed in the jade, and the skin and the jade inside are the same. The color on the skin should be shallow and deep, and the color on the crack should be from shallow to deep. However, the really good seed jade is not long, even if it is, it is a little bit of a star, or in a small crack. The color of the living skin is revealed from the jade.
Identifying from the pores of sweat
The presence or absence of sweat pores is an important point in identifying true and false and Tianyu seed materials. The real seed, no matter how delicate, its surface, there will be countless fine pores, much like the pores on the human skin. So that's generally talking about sweat pores. This surface phenomenon formed in the natural state is by no means artificially forged. It can be clearly seen under a ten-fold magnifying glass.
Master these five points and identify the seed material is not a problem!
The nylon Camouflage Fabric is usually made of 100% polyamide/nylon fibre. Cordura fabric is the most famous nylon fabric. Sometimes it's coated with PU or PVC.These are woodland ,jungle,desert,sea and sky patterns. After special treatment, the surface of the camouflage has near infrared retardant(IRR) function. At the same time, it can increase the functions of flame retardant and waterproof. In addition, high breaking and tearing strength and good printing color fastness are the basic requirements.It's worn comfortably.It's widely used for bags,vest,sleeping bags ,tent,rain coat and so on.
The greatest advantage of nylon fabrics is strong and wear-resistant. Their wear resistance ranks first among all kinds of fabrics. They are light in weight and suitable for making mountaineering clothing and winter clothing. The elasticity and resilience of nylon fabric are excellent. It has good alkali resistance and reductant resistance. It is not afraid of mildew and moth. Nylon fabric has good low-temperature resistance, and its resilience does not change much when the temperature is below 70 C.
