Secondly, the cross section of old porcelain is generally rice flour with gaps. This new porcelain is dense and made by modern machines.
Second, according to the color of blue and white, judge the Ming Dynasty or the Qing Dynasty, and assist in judging: the porcelain is full-shaped, and the foot is dug over the shoulder in the Ming Dynasty, and the loach back in the Qing Dynasty. Blue and white underglaze red ornamentation is specially used for dating. Thirdly, in the 1990s, counterfeiters invented the method of crushing and wrapping "wax frozen soil" to burn the fire of new porcelain. Is the new porcelain burned according to ancient paintings? Most of them imitate the ancient porcelain of Song and Yuan Dynasties, and then use the miscellaneous soil containing wax and Buddha's west to grind it into fine powder and wrap it in porcelain before burning. After burning, the new porcelain has no fire. Many collectors were deceived by the white glaze and black plum bottles fired in this way in Handan, Hebei Province. Identify this kind of porcelain to see if there is any "waxy" residual soil in the grain. Although this object has no internal heat, it is very dull. Note that counterfeiters often use sticky tomb soil to smear the bottom and lining of porcelain. In case of small mouth plum bottle, observe whether there is a smooth and coherent spiral in the bottle and whether it is different from the outside light color. After entering the 2 1 century, the domestic construction industry is booming, building houses and roads, and ancient kiln sites are constantly appearing. Especially Jin Yuanjun kilns, many of which are located in the east of Taihang Mountain. There is no complete ware in the kiln site, and there are a lot of residual porcelain. The counterfeiter was well informed, bought a bowl bottom for 80 yuan, and burned it again after going back. There are several people in Anyang, Henan who specialize in this. After they bought back the bottom of the bowl, they invited a master who burned Jun porcelain from Yuxian, made blanks according to the style of Jun kiln, glazed them according to the glaze color of Jun kiln, and some even added copper to make red dots. Most of the fake Jun porcelain made by this method is shipped to Beijing antique market, which makes the "players" in Beijing play badly. To identify these fake jun porcelain, we must first look at the shape and age. The real Jin Yuanjun kiln porcelain is mostly hard and not heavy. In order to cover up the traces of tire connection, it is coated with thick glaze. In addition, look at the glaze and brown eyes. The new glaze is dazzling and there are few brown eyes. Some use humic acid to remove luster, the glaze is dull, and the hard flash of Jun kiln is lost. Some were corroded by sulfuric acid, covered with small eyes and smelled sour. The false erythema on imitation Jun porcelain is also different from the true erythema. True erythema is purple, red and blue from the inside out, with obvious color boundaries, while false erythema is monotonous. Old players look at the porcelain bottom first. If they encounter this kind of real fake blank, they must look carefully. Still using the old saying, as long as it looks wrong, it is doubtful. The shape, kiln mouth, fetal bone, glaze color, painting techniques and firing methods are all checked. When looking at Jun kilns, we must be comprehensive and correct. If a commodity doesn't match, you can't buy it seriously. If you want to collect the real thing, you must learn to distinguish the fake. In addition to the above-mentioned fake methods, in recent years, there have also been fake methods of electroplating to imitate black and create light on bronzes. In calligraphy and painting, modern plate-making technology is used for photography and hand painting, and calligraphy and painting are used for freezing and ultraviolet irradiation. The stipulation that the new cultural relics law allows folk collections has activated the antique market in China. Many people who know and don't know the sea compete, and many people are choked by the waves as soon as they get into the sea. There are fakes in the antique market, which is interesting to distinguish. Regrettably, however, those who choked on the water returned to the shore. The times are progressing, and the technology of counterfeiting will be constantly updated. Every friend who is determined to collect antiques and is interested in antique appraisal should go out from collection room to learn porcelain appraisal at the kiln site and jade appraisal at the jade carving factory. The public security bureau has undercover police officers who engage in cultural relics identification, and they will have the opportunity to find out the secrets of fraud, which will definitely improve the level of identification. Never read more books on cultural relics and become an expert. Those books are the experience of predecessors, so they can only be used for reference, not copied. With the development of the times, cultural relics appraisal should also keep pace with the times.
