It is a low-temperature glazed pottery, and clay used for white children, carcass hung by the Su-burning glaze, prime burning temperature higher, amounting to about 1100 ℃. Then, copper, iron, cobalt, manganese and other mineral elements of the coloring agent to make glaze. In the glaze to add a lot of refining of lead and lead ash residue dissolved as cosolvent. After about 800 ℃ temperature firing from. Glaze was dark green, light green, green, blue, yellow, white, brown and other colors, it is referred to as the "Tang" is a kind of colorful pottery. Color of objects in three, some only a few colors have a the above-mentioned, known as single-color or one color with two colors of said two colors, even with two or more of the five colors are known as three - Cai.
Three pottery's glaze contains high levels of lead, lead oxide can be used as cosolvent, will lower the melting temperature of the glaze. In firing in the kiln, the variety of colored metal oxides dissolve in the glaze lead to proliferation and movement of the Quartet, co-infiltration of a variety of colors to create brilliant color glaze, mix, the United States and gorgeous Rose.
It is noteworthy that the blue color of Tang. In comparison, the blue monochrome color, or mix together with other GLAZE blue color, and are relatively rare. It has always been to include the blue color of the most expensive devices Tang, once a certain color in a three blue color, from an economic value that it is far more than the price of the other three color, and is their nearly ten-fold to several times. Color blue color agent is cobalt, it is bright and scarce Mingyan. Cobalt is also estimated for the color agent underglazed color, from Persia, and after the impact of large blue-and-white.
Bright glaze of the Tang Jingying, color purity and taste. In order to achieve this effect, potters were the first facilities in the embryo of a white layer of well-prepared slurry of water, cover the embryo body of impurities, the small gap to fill, it is referred to as the "make-up soil," opaque white make-up soil mainly used Tang to the base before glazing. Where make-up of soil substrate glaze Tang bright, brilliant, significantly enhance the decorative effect.
Tang, the figures and animals are more complicated shapes, colored glaze decoration has become increasingly strong bright, highlighting the main colors, so that degree of color contrast Mingyan on the basis of full play. Shi figures figurines black hair, red face Shi Zhu, clothing Shi colored glaze, it will be painted with the organic combination of GLAZE Tang in a unit, giving a more realistic feeling.
Tang will be the shape of the life and is closely related to architecture, furniture, appliances, animals, characters, etc., can be used as a source of modeling. Tang can be classified into two categories. First, daily utensils, such as: plates, bowls, cups, plates, lamps, pillows, cans and so on. Characterized by a dignified and full. The focus of stability, and gives the feeling of calm generous. At the same time, strive to make it vivid, the images combine with the practical. Second, a wide range of objects. There are figurines, horses, camels, sheep, cattle, dogs, evil spirits and so on.
Tang of the child, the clay is quite detailed and generally a more pure form of kaolin processing. Regardless of clay from Luoyang, Chang'an, or Yangzhou and other areas, must be absorbent, and has strong plasticity. Tang embryos after 1100 ℃ high temperature sintering, the firm, dense texture than ordinary pottery.
Tang of the clay with good plasticity, its rich and colorful style. More complicated due to the production, in addition to square adhesive film used in mud from the other device is more than a wheel-type, impression, the way to complete the sculpture. wheel device, can seem kind of a flat at the bottom of the main focus of which is more stable at the bottom. These vessels are relatively thin mouth, the closer we get to the more thick at the bottom of the tire. This is because the rotating pulling wheel forming embryo, the bottom-up, the upper part of the soil needed expect to start from the bottom of the wheel rotation movement around a circle and gradually FORT HOOD, Texas, at the bottom if too thin, when fired deformation and distortion is also easy to collapse. With molded mud embryo is labeled as mud coating or film placed in the model, the forced suppression, slightly dried out, the fait accompli embryo browser. Tang in the complexity of products such as horses, camels, and so on days, unable to pull by hand to complete the embryo, the use of molded. System was divided into single-mode, two die. Characters such as single-mode figurines, figurines behind the kneading by hand, so many embryos left clear inside and outside the fingerprint. Where produced by mold, most people die before and after the animals die around (animals on the right and left eyes), precision die later modified and local processing, so that the surface to eliminate traces of mold. Products each have a mix of their characteristics, life-like, for similar shapes, but different colors Pour Glaze, a sense of the difference between them open. Sculpture is mainly used for special and more complex objects, but also the use of molded-round and are unable to complete the special needs of the artifacts. Such as the rockery Tang pool, carved from sand by hand, vivid. Adhesion-and-paste is an auxiliary of the main modeling methods, such as pot handle and the flow of the mouth, cans, stoves with local flower decoration, the figures on horseback, on the tomb angle, etc. will not form on Annex have to be less adhesive to complete.
Tang in a class known as "hanging hole", and its bright color, no rust spots mud excavated soil profile remains, such as produced from the workshop in shape. This is from a large tomb, a prominent owner identity, many funerary objects, including artifacts of the process part of the production of particular exquisite, was displayed in the tomb stone of the platform, it is not directly related to the soil contact, as if hanging in the air, free from soil erosion, "hanging hole." "Hanging hole" Tang high price, because of soilless rust, smooth GLAZE, appreciation should be careful not to regard it as the new counterfeit.
Tang colorful, mainly for burial, and its historical, artistic, economic value, to the beginning of this century was a growing recognition of the people. Before the end of the Qing Dynasty, no one cares about, of course, there is no imitation. Mining many of in gold, silver, jade and other antiquities collection, after a space, but turns a blind eye to the Tang that is worthless as they are in the graves, or a smash hit. Early years of the Republic the well-known archaeologists, stone home , Mr. Wang Guowei Tang to have unearthed a great interest, pointing out that its high historical value and artistic value, the restoration of the Tang in China its rightful place in the history of ceramic. At this point, some of Tang was much the same kind of appreciation by the collectors, and its reputation, the price increase. In Tang's products so far, mostly for foreign collectors bought, because the Chinese people out of traditional psychology, with a total collection of items buried with the dead unearthed that the showroom is not auspicious, indecent, so possession of those few. Western people have no such scruples, as long as the like, at Deal or No Deal.
China in the international art auction market, the price of Tang has always occupied the first priority. In December 1998 in the UK auction Forbes a "hanging hole" in the blue glaze Tang Ma record ￡ 3,740,000 at the time the highest price of the Chinese art world.
Tang COA of the vast majority are very hard and their voice of nausea, Yuet-ching did not like the sound of metal. Although Henan (near Luoyang) Tang produced using kaolin, or china clay, but when the temperature enough to burn, but also could not . Of course the real thing due to the production of fetal sub-location, the texture of clay are not the same, formed by Tang Luoyang, Henan Province of the fetal hard white, white flash of yellow; Xian Tang Tongchuan white in the erythema, but also in the flash of white ash, it is better to consolidate County hard, but also to pull the hand motionless; Yangzhou in the Tang fetal red, white, light yellow three and soft.
Most sophisticated imitation Tang early years of the Republic, the liberation of the first, the shift in recent years. Imitation is the beginning of the Republic of China carefully modeled sporadic, they transported from Xi'an to Luoyang tomb of loess, and the origin from the three color professionals burning Yunlai three clay color to the real thing for a model to copy the system into a small roasting kiln, land parcels and then the tomb of friction, but also with binata boil water immersion wash and repeated several times, which has become a high-quality imitation of Tang.
Henan in recent years since more than a private workshop for a large number of imitation , crudely, there is no basis for the original. either through their high-fire, fully porcelain clay, and the sound button Dangdang has become porcelain; either through a low fire, or not by fire, barbecue glaze over after the mold, and soft tires son, a bit hard that is broken. They are rough, can be seen from the cross-section births in a lot of impurities and particles, and then outside again to be Wong estimated price, the very . Variety of their child, everything. More than doubled its production of slip casting mold, so-type thick wall vessels have fingerprints and (splicing) seamless. At the same time, the use of genuine brush the glaze glaze technology, a small glazed pattern Securidaca film, and like materials used spray enamel color technology, glazed coarse and thin cracks. goods in the shape flavor, solemn Fengman, imitation goods posture, lack of Aura.
