For jadeite, the last process of processing is waxing, because waxing is a thin layer of wax on the polished surface of jadeite to make it smoother and more shiny. This process has not changed the various properties of jadeite itself, so waxing is also considered as an upgrading process.

But there are also some jadeites with loose structure in this province. It can also be said that this kind of jade can't be planted in water, and the coarse water is dry. Some merchants often put these things in a wax bath when waxing, that is, soak the finished jadeite in melted paraffin for a period of time, and let the paraffin soak along various cracks on the surface of jadeite, which will make things look better. If the jadeite texture is relatively tight, the wax is only immersed in the surface layer. After waxing jadeite, the pits and holes on the surface can be filled up, and the luster and transparency of the surface are enhanced. So waxing is on the one hand, and on the other hand, some black-hearted businesses say it is waxing, but it is not. But know some "hands and feet" to make jadeite look like waxing.

Second, the difference.

wax

Waxing is to coat a thin layer of wax on the polished surface of jadeite to make it smoother and more shiny. Waxing itself is "essentially" harmless to jade. It just played a role similar to "beauty beauty". Therefore, waxing is also recognized as the process of optimizing ontology.

Dip in wax.

Wax dipping refers to some jadeites that were originally common in water, which have many cracks and impurities and poor quality. And businessmen, for personal benefit. To cheat, soak this jade in melted paraffin to make its surface look smoother and brighter. But in fact, this practice will make the ordinary jade look beautiful for a certain period of time, but it will last for a long time. It will cause more pits and cracks, and it feels ugly that the jade surface has been scratched countless times.

Third, how to distinguish between waxing and non-waxing.

How to distinguish between waxing and non-waxing is also a kind of "eyesight". A discerning person knows at a glance, remember not to be careless, or you will be cheated in the end.

Ultraviolet fluorescence.

The ultraviolet fluorescence of waxed jadeite is stronger than that of waxed jadeite, which is generally blue-white fluorescence with moderate intensity, and even has strong blue-white fluorescence. You can buy a purple light yourself on the Internet. There is a special lamp for jewelry appraisal. )

infrared absorption spectrum

Infrared absorption spectrum can better distinguish waxed jadeite from waxed jadeite. The absorption peak of 73 125px- 1 wavenumber of waxed jadeite is very strong, which is close to zero transmittance, that is, close to the bottom line, while the absorption of 73 125px- 1 wavenumber of waxed jadeite is very weak and far from the low line.

When testing the infrared spectrum of the sample, we should pay attention to whether there is a wax layer on the surface of the sample, especially the jade flower part, and the wax in the pit is not cleaned up. The wax layer on the surface will affect the test results of infrared spectrum and the authenticity of ultraviolet fluorescence.

It takes skill and vision. You have to identify yourself to find the difference. )

Restoration of Wax-soaked Emerald

Wax-soaked jadeite that has been aged can be re-melted by soaking wax, which can eliminate the adverse effects caused by aging. If you don't understand this, you can go to a professional institution for help. )
