Original title: Look at jade with a flashlight, and learn these three tricks!
For many years, I often saw many friends watching the magnifying glass and the flashlight watching jade, and asked some novices: “What are you watching?”, Answered a variety of answers, but it is a bit ridiculous:
A: “I use a magnifying glass to look at the structure, see if it is Russian or Hetian jade or seed material …”
B: “I look at others like this, I also look at it too, in fact, I don’t know what to see, I just want to know what others have seen …”
C: “I want to see if the flashlight is a mountain material or the seed material or whether the mountain flows …”
D: “I want to light up to see if this jade is b+c … goods”
Experts teach you a flashlight to watch the three tricks
“The strong light angle of the flashlight is different, the strong light source is different from the jade, and the results of the lighting methods are different. Some people use the flashlight or back to introduce the delicateness of the jade to others. This is misleading, identifying jade particles The thickness of the thickness can only be hit by 45 ° with a strong light flashlight. “
Look at the three big moves of jade with a flashlight, learn these three tricks, and play stones must be used!
“The First Strip”
Directly look at the texture and thickness.
The flashlight light source is close to the surface of the jade, mainly to see the texture and thickness of the jade.
Strong light flashlight directly shot
On the surface, the inner light transmittance, and the light rhyme is relatively light, while the light rhyme on the quartz rock, marble, and glass hybrid products is relatively astigmatism.
When the direct flashlight is slowly translated, the texture structure of the jade stone can be identified. When the flashlight translates, the light transmission of jade is uniformly indicated that the structure is uniform and the light transmittability is uneven, indicating that the uniform structure of the jade is not good.
Strong light flashlight oblique shooting is an important means to identify the thickness and density of the granular granules of jade stones.
The strong light angle of the flashlight is different, the strong light source is different from the jade, and the identification results obtained by different irradiation methods are also different. Some people introduce the delicateness of jade to others with a direct electrical or back shooting, which is completely misleading. The thickness of the appraisal jade can only be hit with a strong light flashlight at a corner of the corner.
During the appraisal, use a strong light flashlight to aim at a parallel surface of the jade (as much as possible to irradiate the side of the skin), with a 45 ° oblique angle, and to illuminate about 3 to 10 cm from the surface of the jade. It is advisable to see the floc -shaped structure to see the flocculent structure. Multiple points are irradiated. Based on this, it may identify the delicateness of the jade and the thickness of the particles.
Strong light flashlights are an important means to identify whether Hetian jade has hidden impurities or cracks.
During the appraisal, use a strong light flashlight to close the back of the jade, and then slowly move to identify whether the Hetian jade jade structure contains impurities or cracks. When there is impurities There will be a general dark reaction of flashlight light sources, or there are uneven refraction of light change reactions
I fully understand these three tricks. I believe that the average stone is hard to fall, but if you want to practice, you will become a real master. You need to keep in touch with the real thing. Now spreading concise and easy -to -understand jade knowledge is to want more people to stay away from misunderstandings.
[Forwarding and praise is the best appreciation]
