Why is jade waxing? How to distinguish jade waxing and waxing?
After the jade is carved and polished, the last process is waxing. All the jade products have to be waxed. This is a complete jade jewelry. If it is not waxed, it seems that there is no protective layer. After the jade jewelry is carved, the waxing can not only protect the jade, but also increase the glamour of the jade jewelry, making the jade jewelry look more beautiful. The following China Jewelry Merchants Network Xiaobian gives you a detailed introduction to several ways of waxing jade, how to distinguish jade wax and dipping wax?
First, jade waxing
Waxing is done by blending the paraffin and applying it to the surface of the jade, keeping it for a while, so that the paraffin is cooled and then more wax is removed, so that the wax is immersed only on the surface. The jade is waxed to fill the small pits and small pores on the surface to enhance the gloss and transparency of the surface. However, no matter whether the jade jewelry is waxed or not, it should not be in contact with acids, alkalis and organic solvents. These chemicals will corrode the surface of jade jewelry. Also, don't put the jade jewelry in the box for a long time. After a long time, the jade jewelry will also "water loss" and dry out.
Second, jade dip wax
Dipping wax is to throw the polished jade product into a hot paraffin solution for cooking. In the process of boiled paraffin, jade will also be thermally expanded, and the gap between the jade crystals will increase, and the paraffin will melt into the crystal gap. At this time, the paraffin wax not only melted on the surface of the jade, but also entered the interior of the jade meat. Dipping wax can only be used for jade with loose texture and poor water quality. For jadeite with high density, it is also a jade with good water. It is not necessary to be waxed.
So how do we distinguish between waxing jade and waxing jade? In fact, by observing their characteristics, it is easy to distinguish between wax-impregnated jade and waxed jade, which have the following characteristics:
1, ultraviolet fluorescence
The ultraviolet fluorescence of the waxed jade is not strong with the impregnation of the jade. The ultraviolet fluorescence of the wax-impregnated jade is generally medium-intensity blue-white fluorescence, and sometimes even has a strong blue-white fluorescence.
2, infrared absorption spectrum
Infrared absorption spectroscopy can better distinguish between two kinds of jadeites: waxing and waxing. The absorption of the waxy jade's 73125px-1 wavenumber is weaker, farther from the low line, while the 73,125px-1 wavenumber absorption peak of the wax-impregnated jadeite is very strong, close to the zero transmittance, which is close to the bottom line. However, when testing the infrared spectrum of the sample, pay attention to whether there is a wax layer on the surface of the sample, especially the jade flower piece, and the wax in the pit is not wiped clean. The wax layer on the surface is likely to affect the test results of the infrared spectrum and also affect the authenticity of the UV fluorescence.
Most jade jewelry will be waxed, so wearing it for a long time may make the jade jewelry dark, so you can go to the reputable jewelry store to polish and renovate. Re-finishing and polishing will make your jade jewelry look fresh and re-emerge.
