-Colored jade inscription
Colorful jade (also called colorful jade) belongs to siliceous bedrock, which is basaltic magma erupted by Precambrian submarine volcano and formed by interweaving metamorphism at high temperature and high pressure. Therefore, colorful jade is hard, generally above 6.2 degrees Mohs, and the best can reach 7.0 degrees. The stone is highly silicified, colorful and all kinds of patterns are natural. This is obvious to all. Stone contains a variety of mineral chemical components, and each component has evolved into a certain color. Of course, there are many factors that produce different colors. For example, in the process of metamorphism, rocks can be gradually interwoven into various colors from primary colors, inherited colors, authigenic colors and secondary colors. But one thing is certain: Caiyu is unique in quality and color. Although it is called colorful jade, in fact, the color of stone is far more than seven colors, which can be summarized as follows: red as blood, green as jade, green as horn and white as silver; Black as ink, purple as rosy clouds, miscellaneous as colorful exercises and yellow as gold. As far as colorful jade is concerned, it is actually divided into cinnabar red, heavy bordeaux red, chicken blood red, rose red, thousand-layer red and so on. Bright color, eye-catching and pleasing to the eye, delicate feel, and its special crystal structure can be observed on the magnifying glass.
Xu Shen in Han Dynasty said in Shuo Wen Jie Zi that "the beauty of jade has five virtues". The so-called five virtues refer to the five characteristics of jade. There is a tough texture, glittering and translucent luster, gorgeous colors and dense and transparent organization, which is the beautiful stone of Shushi. Jade is not only the beauty of stone, but also the embodiment and symbol of Confucian morality. The ancients personified the characteristics of jade, believing that jade has five virtues of "benevolence, righteousness, wisdom, courage and purity" and that "a gentleman is better than jade" In the 5,000-year history of China, jade has always been regarded as a symbol of brightness, perfection, kindness, honesty, wealth and power.
Colorful jade has a unique beauty and health care function. Today, with beauty becoming fashionable, this function of colorful jade is especially valuable for development. According to medical literature, there is such a prescription in the famous medical book Duijilu in Song Dynasty: "There are scars on the face and body, and the real jade will be worn away day by day, but it will disappear after a long time." According to historical records, The Biography of Wang Han Mang records that when Wang Mang was alive, there was a minister named Kong Xiu. Wang Mang wanted to marry him well and give him a jade bottle. He said to him, "I really see that your face is scarred, and the beautiful jade can disappear." . The medical and fitness effects of jade on human body have long been discovered by human beings. There are works in Shennong Herbal Medicine, Tang Herbal Medicine and Compendium of Traditional Chinese Medicine in China. According to the eighth volume of Compendium of Materia Medica-Epistemology, jade has the following therapeutic effects: removing stomach heat, relieving asthma, nourishing hair, nourishing five internal organs, softening tendons and strengthening bones, quenching thirst, moistening heart and lungs, helping voice and throat, calming the heart and calming the nerves, benefiting blood vessels and brightening eyes and ears.
Caiyu contains more than 30 kinds of trace elements beneficial to human body, such as selenium, zinc, nickel, cobalt, manganese, magnesium and calcium. The start-up waves emitted by these elements are in the same fluctuation state as those of human cells. Human cells produce * * * sounds and * * vibrations with the fluctuation of jade, which makes human cells more energetic, promotes blood circulation, enhances metabolism and removes wastes in the body.
Caiyu is the jade contained in the central mountain range of Hualien, Taiwan. The minerals contain emerald serpentine and metamorphic rocks, which are suitable for making vases and other handicrafts. Because of its exquisite workmanship, magnificent and glittering colors, various types and novel styles, it has been marketed in Taiwan Province Province for 20 years, and it has also been popularized all over the world during this period, and is deeply loved by people all over the world. However, due to the limited raw materials and complicated working procedures, it is not easy to process. As a result, the quality and quantity of products made every year are deeply affected, and the products that can be made are limited and cannot be mass-produced. The colorful jade in Taiwan Province province has the characteristics of bright colors and slightly transparent crystals, and the jewelry colors that people all over the world like (such as red as ruby, blue as sapphire, purple as violet, etc.) make people look different. At the same time, it also has the particularity of cultural exchange and the uniqueness and value-added of scarce products; Make it the best choice for government officials and business people to give each other gifts.
Caiyu in Taiwan Province Province is one of the minerals produced in the central mountain range in the east of Taiwan Province Province. Because it overlaps with the vein of jasper in Taiwan Province Province, sometimes the mineral contains jasper in Taiwan Province Province, which is called emerald serpentine metamorphic rock. Colorful jade is gorgeous and crystal clear, waterproof and acid-resistant, and is suitable for making various artistic vases and containers.
The difference between serpentine jade and similar jade. Similar jadeites are prehnite and hydrogrossular. Their differences are mainly identified from hardness, density, refractive index, magnifying observation and so on. Prehnite: It is composed of fibrous prehnite aggregate with hardness of 6-6.5, refractive index of 1.63 and density of 2.88g/cm3. It is anisotropic, foamed in hydrochloric acid and has radial fiber structure. Hydrogrossular: hardness 7, refractive index 1.72, density 3. 15-3.55g/cm3, isotropic body, granular structure, and many small black spots. In addition, serpentine jade is easily confused with jadeite and nephrite, but its hardness is less than jadeite and nephrite. Emerald has obvious waxy luster, while jadeite and nephrite are both glassy luster. It is easy to distinguish them by testing hardness and observing gloss.
Evaluation and purchase of serpentine jade. The quality evaluation of serpentine jade is carried out from the aspects of color, transparency, texture and fragmentation. First, the brighter the color, the better, and the more uniform it is. Second, the higher the transparency, the better; Third, the finer the texture, the better; Fourth, the bigger the better. Serpentine jade has many producing areas, many varieties, large output and low hardness. It is a low-grade jade material, far less precious than jadeite and nephrite. The evaluation factors of serpentine jade are also the basis for purchasing jade products, and attention should be paid to the fineness of workmanship in its value.
