Jade Overview & Map Weather Transportation Information
Jade is an ornamental stone. The term jade is applied to two different rocks that are made up of different silicate minerals. Nephrite jade consists of the calcium- and magnesium-rich amphibole mineral actinolite (aggregates of which also make up one form of asbestos). The rock called jadeitite consists almost entirely of jadeite, a sodium-and aluminium-rich pyroxene. The trade name Jadite is sometimes applied to translucent/opaque green glass.
History
During Neolithic times, the key known sources of nephrite jade in China for utilitarian and ceremonial jade items were the now depleted deposits in the Ningshao area in the Yangtze River Delta (Liangzhu culture 3400C2250 BC) and in an area of the Liaoning province in Inner Mongolia (Hongshan culture 4700C2200 BC). As early as 6000 B.C. Dushan Jade has been mined.
In the Yin Ruins of Shang Dynasty (1,600 B.C. to 1,050 B.C.) in Anyang, Dushan Jade ornaments was unearthed in the tomb of the Shang kings.
Usage of Jade
Jade was used to create many utilitarian and ceremonial objects, ranging from indoor decorative items to jade burial suits. Jade was considered the "imperial gem". From about the earliest Chinese dynasties until present, the jade deposits in most use were not only from the region of Khotan in the Western Chinese province of Xinjiang but also from other parts of China, like Lantian, Shaanxi. There, white and greenish nephrite jade is found in small quarries and as pebbles and boulders in the rivers flowing from the Kuen-Lun mountain range northward into the Takla-Makan desert area. River jade collection was concentrated in the Yarkand, the White Jade (Yurungkash) and Black Jade (Karakash) Rivers. From the Kingdom of Khotan, on the southern leg of the Silk Road, yearly tribute payments consisting of the most precious white jade were made to the Chinese Imperial court and there transformed into objets d'art by skilled artisans as jade was considered more valuable than gold or silver. Jade became a favorite material for the crafting of Chinese scholars objects, such as rests for calligraphy brushes, as well as the mouthpieces of some opium pipes, due to the belief that breathing through jade would bestow longevity upon smokers who used such a pipe.
Categories
Jade in China is varied and can be divided into two categories: Jadeite (hard jade) and Nephrite (soft jade).
-
As early as the 16th century, Jadeite was believed to be a precious and jadeite (hard jade) with healing qualities. Since it was brought into China during the early Qing Dynasty (1644-1911), it had been doted on greatly. Jadeite contains an iron component which appears red, chromium that appears green, and many other colored types. Known as the "king of jade", it is usually a more expensive type of jade.
-
Nephrite's robustness is due to the fact it contains tremolite. It also can be divided into several sub-classifications according to color: white, grey, green, topaz, and black jade.
Hetian Jade
In China, the most reputable jade producing area is Hetian in Xinjiang Province.
Hetian jade is so hard that it can scratch glass. It has often been found in very huge pieces. Besides, serpentine jade from Xiuyan County in Liaoning Province, Lantian jade produced in Lantian County, north of Xian in Shaanxi Province, and Nanyang jade of Nanyang County in Henan Province are very famous.
Patterns of Jade
The patterns of China's jadeware have rich connotations, revealing strong, auspicious colors.
Bats and gourds were used as subjects for more than 100 patterns because the Chinese words "bat" and "gourd" sound like "good fortune" in Chinese. When a bat was carved on an ancient coin with a hole, it meant that fortune was at hand; bats coupled with birthday peaches referred to fortune and longevity; bats mixed with sika, birthday peaches and magpies were also considered good omens. These beliefs reflected the ancient Chinese people's yearning for a happy life and revealed the essence of China's traditional culture.
