(A) scientific and technological means, such as "TL" and "cremation seed analysis", these two methods error is small, measuring age of porcelain firing accuracy rate is higher, but the test is required when drilling in artifacts hole, remove the small sample, will produce damage artifacts.
(2) by virtue of experience with this method, although subjective factors, but its simple, unaffected by other conditions, so the current identification of the authenticity of porcelain mostly used this approach.
We are here talking about "experience" refers not only to understand the chinaware fake way, but also to understand the dynasty porcelain at different times of the shape, glaze and firing conditions change, sometimes need to use the "reasoning" way to help us identify the authenticity. For example, we are now in the antiques market and some private collections from time to time you can see the Northern Song dynasty "official Jun" products, there are pots of care, nail wash drum and the like, its production said in the past, and also the bottom Jun engraved confirm its official "identity" of digital numbers, which for some even very rare porcelains genuine opportunity to get started ceramic collectors concerned, is undoubtedly a "chance."
But only, after the expert an appraisal, I discovered that they pay "tuition." In fact, identification of the authenticity of the Northern Song Dynasty chinaware kiln product should be one of the most simple thing, it's just a common problem: the establishment of Northern Song court chinaware kiln production is exclusively for Queen's, prohibited the use of folk, who burned all smashed buried. 70 Jun Taiwan kiln in Yuzhou comprehensive excavations, chinaware kiln products have not been applied a complete, can be seen by the official Jun use is strictly limited, it can not dispersed in society. So now we come into contact with in the market Songguan Jun porcelain is basically false.
Jun modern imitation general, or from the place of origin of God Hou Yuzhou town, where not only the fine tradition of firing porcelains, but also focus on a number of today's finest porcelains produced master. God Hou town chinaware produced at a rapid pace in recent years to move forward with, whether it is the shape of objects, or a glaze changes have greatly improved and enhanced, but in the face of fierce market competition, it also faces the marketability of the product problems.
Several authors are familiar chinaware artists complained: Now collectors do not like the new goods, some thick old book today. In this case, God Hou also began production of antique porcelain chinaware, such as statues, bottles, stove, bowl, bowls, plates, etc., its shape is generally italics, gold, Yuan Dynasty kilns the shape, the production process and spot color decoration also sought similar. Antique porcelain production itself is understandable, but if artificially's do the old, filled in the antiques market, not only will the image of the ancient porcelains prejudice, but also easy to make the antique market confusion.
2, to identify the authenticity of dynasty porcelain, from the following aspects:
First, look at its production process. Jun kiln porcelain from the start at the beginning of the "Tang Jun", after the Song, Jin, Yuan, Republic of imitation until Jun blanks are used is hand craft. This process is characterized by thick bottom utensils, and then gradually upward trend thin rim artifacts carcass at the thinnest. Lucy in the glaze at Quanzu artifacts can also see fine rotation pattern, wall thin enamel at a round finger marks.
Some modern imitation porcelains is mass production, it uses a material made molds, then use the "grouting" perfusion. This method is made out of porcelain tire uniform wall thickness, lighter weight, more crudely that due fettling not fine, you can touch both sides of the objects into the mold seam marks, which is the most botched a fake person practice, some smart objects in the interior of the bottle body such as bottle type, it is difficult to detect the site of some other substances stick artificially (such as cement) to achieve a heavy feeling ancient porcelains. Or "grouting" wall molding artifacts deliberately made round fingerprints, but on closer inspection you can see the real "Hand blanks" uniform fingerprints are different, not only mimics the rough wheel finger marks, and each ring ring ring finger marks with each distribution is extremely uneven.
Secondly, look at its glaze and enamel. Song dynasty porcelain azure, sky blue, white glaze, uniform shiny, opalescent included, although dating back nearly a thousand years of history, but because of the Central Plains groundwater content is less, the amount of alkali in the soil medium, So whether it is burial or kiln porcelains unearthed hidden, very few chunks of soil rust bonding phenomenon, which tend to produce outstanding enamel porcelains, very enjoyable. Modern imitation italics Jun Jun is whether the shape, or imitation gold, the characteristics of the Yuan Dynasty porcelains, which are mostly sky blue glaze, with little azure, white glaze. And in order to achieve similar enamel porcelains unearthed deliberately falsified soil to the floating light rust or for processing, but its effect is negative, giving the impression that the glaze black hair, not natural, looks extremely uncomfortable.
For the old and distinguished its approach to the following categories:
(1) using tools such as chinaware skins repeated friction surface, in order to achieve to their floating light effects. While the glaze is smooth, but careful observation under a magnifying glass, you will see numerous parallel friction marks.
(2) into the new imitation porcelains with a corrosive acidic solution such as immersion, although it could make the porcelain surface loses bright floating light, to do the old effect, but often seem very dull glaze in under a magnifying glass you can see the scars.
(3) are sometimes fake is also aware of the above methods to harm glazed porcelains, so it uses a soft cloth containing oils throwing fight, the same can produce soft glazed effect, but with genuine glazed smooth delicate touch significantly different, fake processed glazed porcelains touch with oil texture.
(4) After soaking in an acidic substance, immediately to cover the soil, making artificial soil, rust, rust penetrate the soil and this glaze, it is easy to deceive collectors fooled. In fact, according to the North in recent years unearthed chinaware, and Kwan Taiwan kiln porcelains excavated a large number of specimens obtained perspective, Jun porcelain surface soil rarely rust, rust appeared bulk soil bonding phenomenon is even more rare , mostly showing a smooth and delicate effect. Some fake made by the adhesive bonding of soil rust illusion, in fact, self-defeating, superfluous move.
(5) Human enamel peeling phenomenon. Fake porcelains are sometimes deliberately ripped the bottom part of the foot part of the glaze layer, exposing the aggravation, in order to achieve age-old gives the feeling. Because modern imitation Jun genuine and ancient porcelains made from the same raw materials fetal origin, so the color is very close to the tire. But with genuine natural peeling enamel careful comparison can be found adulterants flaws: genuine enamel stripping section is substantially straight stubble, adulterants enamel stripping section is inclined stubble.
For dynasty porcelain identify, in addition to the above points, you can also be considered from the following aspects:
Jun porcelain glaze on genuine massive kiln spots of purple; imitations kiln lighter spots is not too deep. Imitation fetal color slightly lighter than the real thing, but because the ancient practice Amoy mud tires complicated process, so Taizhi delicate dense and modern chinaware fetal mud Amoy practice is relatively simple, sometimes with impurities or section Taizhi produce pores.
According to the author's many years of chinaware production observed most modern imitation of Jun porcelain is produced neat reach Song Jun, Yurun crystal glaze process effect, mostly imitations but relatively close to the gold, the Yuan Dynasty porcelains style However, tires, glaze and gold, dollar and it looks relatively thin compared to the period.
In short, the authenticity of chinaware able to distinguish between day and night is not completely grasp the knowledge, it needs to accumulate and continue to learn, observe and try to figure out, but more often to understand the development of modern chinaware production process changes and imitation Kwan new trends .
