How to buy jade using flashlight
Flashlights are a common tool for identifying jade and are also very important tools for judging jade. The intensity of the flashlight is different, the strong light source is different from the jade, and the identification results obtained by different illumination methods are different. How to correctly use the flashlight to identify jade?
First, the misunderstanding of the lamp
1, look at whiteness
Under the light, it is easy to see people in the moon and the moonlight. If the light is too strong, the light reflected by the jade is also strong, and the light is dark, and the reflected light of the jade will be gray. If the light is color cast, the whiteness of the jade itself will be greatly affected. A piece of jade is cold, but if the light is warm and yellow, take down the jade, the jade is warmer, and there is no yellowing jade. It was a pale yellow color. So why do you say that "the jade does not look at the jade" is the truth. If you want to see the whiteness of Hetian jade, it may not be a wise choice to watch the jade under the lamp.
2, see the structure
There is a popular saying in the market that there is no structure for lighting. The meaning of this sentence is that the structure of the material is dense and the structure is so thin that it can hardly see the structure under the illumination of the flashlight. Is there really no structure for the so-called no structure? In fact, the problem is precisely in the usage of this flashlight, there are a lot of tricks.
Many newcomers are looking at them with lights like this:
Take the white jade in one hand and the flashlight in the other. At the bottom is the flashlight (the light is vertical upwards); the middle is white jade, the light just passes through the white jade; the top is the eye, just the light can reach the eye through the white jade. Three points are in a straight line.
Such an approach may damage the eyes and not say. Just looking at the structure, it is also difficult to see any judgment, and most of the white jade with a good structure can be "transparent and unstructured" under such light. On the contrary, the "transmission" behind this will make the jade singularly shine better than itself, affecting our consideration of value.
It can be said that blindly behind the lights is a lack of professional performance, it is likely to be the fuse that is being slaughtered by the merchants. So how should you use your flashlight correctly?
Second, how to use the flashlight correctly?
1, front direct light
Put the flashlight on the surface of the jade at 90 degrees, slowly move the flashlight, and check the size of the aperture to judge the light transmittance inside the jade. This is a very important use for frontal lighting. Especially when looking at some raw materials and raw stones, the front is polished. According to the difference in the transparency of jade, it can help us to judge the uniformity of meat quality and evaluate the risk inside jade.
For example, a piece of stiff raw material, with a skin and a twilight outside, is difficult to tell whether it is stiff or flesh. At this time, a dozen flashlights can be used to know whether it is stiff or flesh.
2, side lighting rotation
Side lighting is the most common and important way to polish. The specific method is as follows: the flashlight is placed on the side of the jade, and the jade is polished at a 45-degree angle, and the jade is slowly rotated.
Through this side lighting method, we can clearly see the internal structure of jade, which is very important for us to evaluate the quality of a piece of jade. At the same time, in the slow rotation, some "hidden" cockroaches will also appear, such as the waterline.
In addition, regarding the fineness, whether it is behind the lamp or direct front, it is difficult to objectively see the fineness of the jade. Only under the rotation of the side light, the interweaving structure of a piece of jade can be fully revealed. Many indicate that there is no structure for lighting. The jade, in fact, it is difficult to really "the side lights have no structure."
In fact, for many masters, lighting is not a professional level. The light perception under natural light can actually reflect the jade situation most. In many cases, the shape, skin color and whiteness of a piece of jade should be judged under natural light, so we can see those common traces in the stockyard and Bazaar. The Adassis, few people are looking at the stone with a flashlight.
