Basic introduction of Lantian jade
Lantian jade is a famous ancient jade, which was mined and used to make jade seals as early as the Qin Dynasty, and has the famous He Shi Bi.
. There are records of Lantian producing beautiful jade in many ancient books before the Tang Dynasty. According to records, Emperor Ming of Tang once ordered people to pick Lantian jade to make a qin (a percussion instrument) for Yang Guifei. According to his "Geographical Records" in the Book of Han, the beautiful jade was produced on the Lantian Mountain in the north of Beijing (now north of Xi'an). Afterwards, there were ancient books such as "Biographies of the Outer Qi" in the Book of Later Han, "Ode to the Western Capital" by Zhang Heng, "Guangya", "Commentary on the Water Classic", and "Gazetteer of Yuanhe Commanderies and Counties". During the reign of Emperor Wanli of the Ming Dynasty, Song Yingxing wrote in his book "Tiangong Kaiwu": "The so-called Lantian refers to the other name for jade produced in Congling (Kunlun Mountain), and later mistakenly thought it was the Lantian of Xi'an."
What is the nutritional value of Lantian jadeHow did the history of Lantian jade come aboutHow to distinguish the authenticity of Lantian jade1. Characteristics under polarized light microscope: Lantian jade from Shaanxi is serpentinized marble, calcite is mainly in granular structure, and leaf serpentinite is mainly in cryptocrystalline structure and scale crystalline structure; And the cryptocrystalline structure formed by serpentinite metasomatism of marble can be seen, as well as minerals such as diopside, olivine, and a small amount of muscovite with well preserved crystal shapes.

2. Electron probe results show that the chemical composition of Shaanxi Lantian jade is very close to the theoretical values of calcite and serpentine. The high content components are oxides of Si, Mg, and Ca, while the low content components are mainly oxides of iron and aluminum, followed by oxides of potassium, sodium, manganese, titanium, and chromium. Among them, the iron content in serpentine is relatively high. 3. The X-ray powder diffraction test results show that the main mineral component of the transparent yellow and green parts in Lantian jade from Shaanxi Province is serpentine, with a small amount of calcite, dolomite, etc., similar to Xiuyan jade from Liaoning Province, showing the characteristic pattern of serpentine
4. Infrared absorption spectroscopy shows that the main mineral components of the transparent yellow and green parts in Shaanxi Lantian jade, in addition to leaf serpentine, also have a small amount of transparent luster.
