My system is not decent

The exact origin of the phrase "thousand-year-old jade turns into okra" is unknown, but it is familiar to those who play with ancient jade.

There are many versions of this sentence, such as "thousand-year-old jade becomes okra", "thousand-year-old jade surpasses okra" and so on.

There are also many versions of the interpretation of this sentence, but most of them are analyzed from the discoloration of ancient jade, and the convincing power of the conclusion is limited.

However, it cannot be denied that this is a phenomenon.

And this phenomenon just shows that even white jade and sapphire may turn into okra-colored topaz.

Okra is a kind of annual herbaceous plant, which is native to Yinsan. It is cultivated in my country from Qilu, Beihe to Guangdong Province, Nanhai and other places.

Its petals are light yellow, the flesh of the fruit is turquoise, and the seeds are white.

Of course, it is not accurate to use the color of okra to describe the color change of ancient jade.

Among the high ancient jades before the War Han Dynasty, there are some sapphires and slightly yellowish sapphires. The jade is very oily and dark in color, barely similar to the color of okra.

But that is the original color of jade, so it cannot be said that the thousand-year-old jade has turned into okra.

Among the ancient jades before the Tang and Song Dynasties, there are many jade articles made of white jade.

Some colors remain white without obvious change, while others are slightly yellowish.

But it is far from the color of okra, at most it can barely be regarded as the color close to the color of okra flowers.

But even so, it is difficult to accurately interpret the meaning of "thousand-year-old jade turning into okra".

Among the middle ancient jade and the high ancient jade, it is not uncommon for the jade color to appear light yellow, just like the two pieces of jade Lion Mountain unearthed from the tomb of the king of Chu, but it is also not universal.

Moreover, the light yellow color of some ancient jade is not the color change after being buried in the soil, but the color of the jade itself.

In any case, it can be proved that some topaz is not topaz, but also related to the characteristics of topaz.

For example, when Wang Yi, a writer in the Eastern Han Dynasty, recorded the color of jade in "On Jade", he said: "Today, there are always white ones, and sometimes black ones, but there are absolutely no yellow or red ones."

It means that there are absolutely no topaz and ruby!

This makes many people feel very confused. Are those yellow jades that we usually see are fake topaz?

In fact, it is not an exaggeration to say that it is false.

Because it stands to reason that topaz in the true sense should be native yellow Hetian jade.

Such jade, even in today's advanced transportation, information, and logistics, few people have seen it, and it only exists in legends.

Since ancient times, Chinese people have been extremely obsessed with yellow. Yellow is like the color of the sun. Yellow looks noble because it has been the color of emperors since ancient times.

But when it comes to topaz, many people will think of it as Huangkou material or Qin material. In fact, Topaz is completely different from Huangkou and Huang Qin.

The thousand-year-old jade that turns okra color is actually a kind of Huangqin.

The real topaz is produced in Xinjiang Province, which is the original topaz mine. Huangkou and Huangqin are both formed by the white jade bottom being stained by iron elements.

What is the mysterious and scarce topaz?Why is topaz rare in the market?

Most of what we see in the market are Huangkou material and Huangqin, while Huangyu, the ancient jade that is often seen at major auctions, is almost all Huangyu from the Ming and Qing Dynasties.

The batch of materials discovered by Chen Wenzhe is obviously left over from this period.

Otherwise, in modern times, there will definitely not be so many top-quality topaz materials left.

So now, why did Topaz disappear?

Topaz is produced in Xinjiang Province, and the output is scarce. Most of the topaz produced are gray, bluish white, and the yellow color is not pure.

The topaz produced during the Ming and Qing Dynasties were of high quality, but in modern times the output plummeted, and the ore was almost extinct.

Later, Huang Kou material and Huang Qin were discovered, which made up for the regret of the lack of Huang Yu!

Therefore, some of the "topaz" we usually think of are Huangqin, Huangkou or Huangpi.

Although they are all yellow, there are still many differences compared with real topaz.

Let me talk about Huangqin first. This kind of jade includes Quanqin, Banqin, Piqin and so on.

Many modern people like to regard Huang Qin as topaz, but Huang Qin is not real topaz.

Because the yellow color of Huang Qin is not original, but caused by the infiltration of ferric ions in the later stage, it is a secondary color, and its color gradually becomes lighter from the outside to the inside.

And according to the depth of Qin, we generally divide Qin materials into three types: skin Qin, half Qin and full Qin.

Piqin is a thin layer of skin that becomes piqin, which is slightly thicker than skin color, so it belongs to Piqin;

Half Qin refers to half of the jade meat that has been soaked in color, and the innermost part is still white meat, and Quan Qin refers to the entire piece of jade meat that has been soaked through.

And it is worth mentioning that although a good piece of Quanqin is not topaz, after cutting it open, you can see that there is all yellow Qin meat inside. It is really beautiful, and it is estimated that it is not much worse than real topaz!

In modern society, there are things related to Topaz from time to time, and it will be lively on the headlines of Moments.

Although most of them are ancient jade, no matter what, playing with topaz is also a very face-saving thing.

So, what exactly is topaz?

Just "yellow Hetian jade", can it be called topaz?

Obviously not, many people subconsciously think that topaz should be a precious "high-end material".

However, the output of Huangkou materials is large, and most of them are mountain materials, so "unqualified" is called topaz.

In addition, it is also because the color of many yellow mouth materials is actually "green and yellow", not so "thoroughly yellow".

However, in some auctions, or some books and merchants, Huangkou is called Topaz.

The yellow color of Huangkou belongs to the original color, which is caused by metal ions in the metallogenic stage, based on white jade and green white jade.

The color has various shades such as light yellow, medium yellow, and blue-yellow.

Huangkou is not the official scientific name. According to the cause of formation, it is actually a branch of Baiyu and Qingbaiyu.

Scientifically speaking, the original yellow Hetian jade can be considered as topaz, so there is nothing wrong with saying that the yellow mouth material is topaz.

It is generally believed that the best yellow mouth is Ruoqiang yellow mouth material. Ruoqiang material is mostly light yellow, has excellent hardness, and is very oily after being made into a finished product.

In addition, in terms of texture, Gobi yellow material is also a high-quality yellow material, and its production area is mainly around Korla.

The material here has a greenish-yellow hue, and the jade is equally tough.

But in terms of color, of course, the more positive the better, the yellower the better, preferably close to "chicken oil yellow".

This is Huangkou. This kind of topaz has a large color span and many origins.

In the auction house, yellow materials are basically uniformly written as topaz.

Although we know that Huangkou is not a real topaz, Huangkou is one of the closest existences to topaz.

Many people choose yellow mouth because some yellow mouths are yellowish and the jade is of good quality. From the appearance, they can basically replace topaz, and also make up for the lack of topaz to a certain extent.

However, the color span of yellow mouth material is very large. Although there are light yellow millet yellow and yellower chicken oil yellow, there are also less yellow green yellow mouth, and this kind of blue yellow color is especially abundant in yellow mouth.
