Why can t the old jadeite pass the machine inspection?

First of all, the old jadeite with natural jadeite texture must be able to pass the detection, and there are two reasons why it cannot be detected:

1. Old jadeite, at the beginning of production, there was a process of artificial dyeing, and at that time, the color was heavy and light.

2. Now the antique optimization of jadeite, in the name of old jadeite.

Either way, this kind of jadeite cannot be used as a collection.

Identification method:

1. Look at the cotton, there are very few old jadeite cotton, even if there is, the cotton is also a subtle dot, and the new jadeite cotton is more, and it is also accompanied by a lot of things like ice slag.

2. Look at whether it is gelatinous, the old jadeite sometimes gives people a very transparent visual and at the same time feels that the flesh seems to contain gelatinous substance, and the gelatinous substance is evenly distributed.

Soluble in meat. It gives people a very down-to-earth and connotative feeling, and the new species will not.

3. Look at the fluorescence, the old jadeite with good water sometimes feels that there is a kind of light radiating from the inside of the jadeite, which is soft and connotative.

There are two reasons for this:1. Old jadeite, at the beginning of production, there was a process of artificial dyeing, and at that time, the color was heavy and light.

2. Now the antique optimization of jadeite, in the name of old jadeite.

The old jadeite with natural jadeite texture must be able to be tested by the machine.

Introduce. The correct definition of jadeite is a fibrous aggregate of pyroxene minerals dominated by jadeite minerals. But jadeite is not equal to jadeite.

Jadeite is a jade-grade stone polycrystalline aggregate formed under geological action, mainly composed of jadeite or jadeite and sodium (sodium chromium pyroxene) and sodium calcium pyroxene (omphacite), which can contain hornblende, feldspar, chromite, limonite, etc.

If it is a natural old jadeite, it will definitely be able to pass the national inspection, for example, you take the old jadeite in the Forbidden City to test. Now there are a lot of so-called glass imperial green on the market, Fulushou colorful jadeite Qing Dynasty old jadeite, more advanced than the jadeite worn by the Empress Dowager Cixi, but can not pass the national inspection, in fact, are B + C goods, some are quartzite and other dyeing substitutes. This kind of stuff is not collectible!

Therefore, everyone must keep their eyes open, don't keep thinking about picking up leaks, believe in science, and spend less money
