The porcelain of Ge Kiln is engraved with official characters. Here is a brief introduction to Ge Kiln and its identification method. Ge kiln porcelain is mainly in antique styles such as furnace, bottle, washing, plate and bowl, and its most notable feature is that there are small cracks at the big opening, which is called "gold wire and iron wire". The glaze of Geyao porcelain belongs to matte glaze, and the glaze layer is extremely thick, and in some places it is as thick as a fetus, which makes the appearance of the ware round and full. The matrix of Geyao porcelain is mostly purple-black, iron-black or yellow-brown, indicating that the tire material contains more metal impurities such as iron, so it also has the characteristics of "purple mouth and iron foot". As a rare porcelain, imitation Geyao porcelain appeared in large numbers from the Ming Dynasty and reached its peak in the Qing Dynasty. Its fidelity is often difficult to distinguish between true and false.

Identification method of Geyao porcelain

Ge Kiln is one of the five famous kilns in Song Dynasty recorded in literature, and it is a famous kiln whose exact kiln site has not been found so far. Ge kiln porcelain is very precious. According to statistics, there are about 100 pieces in the world, far less than the number of Yuan blue and white flowers. In the international auction market, every time one item appears in the past two years, the average transaction price is several million dollars. At present, more than 95% of Geyao porcelain appearing in the antique market is a modern imitation. At present, the understanding of Geyao porcelain is mainly obtained from two aspects. One is recorded in ancient literature. According to "Washing Begonia in Geyao" on page 175 of "Grand View of National Treasures", "The earliest record of Geyao that we can see now is the Handicraft of Kiln Fixing in Xuande in the third year of Xuande in Ming Dynasty (1428):' Neicang Wood, Ru, Guan, Ge, Jun, Kiln Fixing Device. Later, Amin writer Cao Zhao wrote "On Gegu":' When the old Geyao came out, the color was different. There are purple mouth and iron feet, and the ones with good color are from Dong kiln, which are rare today. Groups of people lined up are all newly burned at the end of the Yuan Dynasty, with rough soil patterns and bad colors. "The most detailed record of Geyao belongs to the" Continued Seven Revisions "published in Jiaqing's forty-five years:' Geyao and Longquan Kilns both originated in Longquan County, Zhou Province. In the Southern Song Dynasty, two brothers, Shengyi Zhang and Sheng, each had a kiln. The one who gave birth to a pottery was Ge Kiln, and the other was Longquan, also named after the place name. Its color is blue, with different shades; Their feet are all iron, and the depth is different. In the old society, purple feet were rarely heard of. "According to these records, people call the world-famous museums such as the Shanghai Museum, the Palace Museum, the percival David China Art Foundation and some collectors' collections of open-cut, purple-mouth or iron-foot green glazes handed down from generation to generation as Ge Kilns. "The second is the orderly spread of Geyao porcelain in the Qing Palace. The main types of pottery handed down from generation to generation are octagonal cups, stoves, washing, plates, bowls, cans, bottles and so on. Glaze colors mainly include cyan, moonlight and shadow blue, with cyan being the most. The carcass color is divided into black gray, light gray, dark gray, khaki and other colors, with black gray tires being the most. The biggest feature of Geyao porcelain is cracking, which is a defect caused by the different shrinkage rate of glaze when porcelain is cooled, but it has a unique decorative effect. Ge kiln is famous for its exquisite through carving, and it is known as gold wire. Its large openwork is covered with small openwork. The big hollow is black and blue, called iron wire, and the small hollow is gold, called gold wire. Judging from the porcelain handed down from the Qing Palace, it does not have the characteristics of purple mouth and iron feet. Some purple mouths have no iron feet, and some iron feet have no purple mouths. Geyao porcelain has been copied from the end of Yuan Dynasty to Ming and Qing Dynasties and even modern times. Most of the imitation Geyao porcelain in Ming and Qing dynasties have year numbers, and some have no year numbers. Compared with Geyao porcelain in Ming and Qing Dynasties, it is quite different in characteristics.
