Hetian jade's collection term: Hetian Baiyu was called Guoyu and domestic famous jade by the Chinese. Also known as the first of the four famous ancient jade. Also known as the court jade, there is also a saying called Ning Weiyu. The favorite jade of Emperor Qianlong of the Qing Dynasty was Hetian jade. "Dazhi Zhishuishanzi" reproduces the spectacular scene of the Dagu River. Opening the door: Describe the ancient jade. No matter the color, the carving, the patina, etc. are top-notch. The viewers are often amazed and pretending to be shocked and stunned: open the door! Open the door! The typical old three generations! If you offer the Emperor Qianlong in 230 years, you will have to enjoy the yellow horse! Oil and chicken oil: Hetian Baiyu and Topaz have been the best of jade since ancient times. Wang Yi’s "Jade Theory" contains records such as steaming millet and white as fat. Topaz can be roughly divided into several kinds of chestnut yellow, chicken yellow and okra yellow, which are rare treasures. The folklore is called the sheep tail oil, which is the sheep fat jade. Many people have not been delusional about topaz, so they are shoddy on the sheep white jade. In the Hong Kong and Taiwan regions, there is even the absurd saying of green sheep fat, or the sale of high prices, or the show of bragging, are all acts of stealing the bell. Rough and clear: Many collectors believe that the jade in the Ming Dynasty was rough, so it was named. The fact is not the same, just like the Hanba knife does not mean that the Han Dynasty jade only uses eight knives, the thick Ming special specifies the rough style of the jade. In contrast, the jade wares of the Qing Dynasty were exquisite and delicate, but there was no such master of the jade as the name of the Ming Dynasty Lu Zigang. Without the foundation stone of the jade carving technique of the Ming Dynasty, how can the appearance of the ancient jade carvings of the Qing Dynasty emerge from the air. Chicken bone white: The ancient jade is unearthed in alkaline soil, and there are many lime stalks, which are white. Lime is different in lightness and weight, so the ancients divided it into white, white, ivory, white, and so on. The ancients did not know the acidity and alkalinity of the soil. They only thought it was caused by the fire. So when the chicken bones were white, they burned the jade with fire. This was very successful during the Republic of China. The contemporary production of chicken bone white is much more advanced, and it can be used for electric welding and microwave Shanghai. As for whether plasma or even atomic energy will be used in the future? It seems imaginable.
