When we buy Hetian jade in the market, there are usually some merchants who say that Hetian Baiyu is a sheep fat jade. It is also very helpless for this phenomenon. Most customers can't really distinguish the difference between ordinary Hetian white jade and suet jade. In the end, they can only be fooled and eat big losses.
Hetian Baiyuyu Yangzhiyu
First of all, we must understand Hetian Baiyu. Hetian Yu believes that everyone knows, and Hetian jade has different varieties such as white jade, sapphire and ink jade. Hetian Baiyu is a more precious jade variety in Hetian jade. Hetian Baiyu has a delicate texture and is lubricated by hand, so it is also very popular in the market.
But what about sheep fat jade? Sheep fat jade is also a kind of Hetian jade, but he is not divided by color, but Hetian jade surface is like sheep fat. The color of the sheep fat jade is only white, slightly blue or yellow, the texture is fine and moist, and the oil is very good. It is the best quality in Hetian jade. Good quality sheep fat jade crystal clear and flawless, delicate and moist, like fat sheep fat meat just cut, the gloss also seems to be a concise grease.
Therefore, there is no necessary connection between Hetian Baiyu and Yangzhiyu. Hetian Baiyu is not necessarily all sheep fat jade. Only a part of white jade whose quality reaches the level of sheep fat jade can be called sheep fat jade!
Sheep fat jade sheep white jade
I have already said that sheep fat jade, then what is the fat white jade?
I often hear people say that sheep fat white jade, in fact, this is just a name for people nowadays. In the past, there was only sheep fat jade, but no sheep fat white jade. This white word was added later. Because most people think that the sheep fat jade is white, it is better to call it sheep white jade.
However, the term "shallow white jade" misleads many people, because the sheep fat jade is not pure white, but pure white is the ordinary Hetian white jade! In the Qianlong imperial poem "å’å‘¨çŽ‰ç´ å£", there is a description about the fat jade: "the quality of this sheep fat white, the color of today's chestnut yellow." So the sheep fat jade is not pure white, but white and yellow.
And the "slim white jade" we often see in the market, this white is mostly pure and white, so many people believe that such white jade is the real sheep fat white. In fact, this is just a deceptive inducement of the business. Let's take a little look at the fat, and we know that the color is not simply white. In the fat jade, oiliness is the most important feature. The oil is good and the fat is sufficient, so the light in the oil is stronger.
Discrimination: Yangzhiyu & Hetian Baiyu
Although the above mentioned the difference between a lot of sheep fat jade and ordinary Hetian jade, but I believe that many people still can not distinguish, do not worry, the following methods are mastered!
1 pure texture
The sheep fat jade contains 99% of tremolite, so it is more pure and flawless than the ordinary Hetian jade.
2 structure is fine
In the microscope, the tremolite is microscopically crystallized and crystallized under the microscope. Therefore, within the same angle under the orthogonal polarized light, there is no uniform extinction phenomenon.
3 water head
Ordinary Hetian white jade is usually translucent or opaque, while the fat head of sheep fat jade is very basic and basically translucent.
4 colors
The sheep fat jade is not pure white, it is a white with oil, the white is slightly yellow, and the pure white must not be the fat jade.
5 oily weight
In the process of touch friction, the surface of jade has a strong oily feel, and the oiliness of the fat jade is heavier than that of ordinary Hetian jade.
"Jade is a spiritual thing, and it has a spiritual atmosphere.
