Now the world’s love of the Yuan Qinghua, resulting in Jingdezhen Yuanqing imitation sales.Jingdezhen’s enthusiasm for imitating Yuanqing is also increasing, and various imitation products of Yuanqinghua are constantly coming out, and from the original low-grade products gradually to high-end imitations.It is really difficult to identify high-imitation products, when necessary, we should use modern high-tech means to identify, but in general imitation, as long as master the knowledge of ancient ceramics process, we can make a clear judgment.Here are some practical comparison of the new and old characteristics of the Yuanqing Flower for your reference.

1: Yuan Dynasty blue-and-white porcelain of heavy and firm, the wall is thicker, more large.Because contains the impurity much, the fetus has the iron-brown small dot mostly.The fetus is made of Gaoling Ma Cang earth.The characteristic of Gaoling marshy soil is white but not fine, because the condition of crushing at that time is limited, the craft is limited, so you can see a lot of stomata.Today’s tyres are very thin without stomata.In the past, old foetus mud, there is a stale process, organic matter through the stale will change.So its tire has a delicate feeling, now do the tire is not stale look very dry.The plasticity of porcelain-making materials produced by modern machinery is generally not as good as those prepared by hand in Yuan Dynasty.Modern Jingdezhen popular ceramic molding process is said: three-part drawing, seven-point cutting.That is to say, the shape of the object is mainly repaired with a knife.On the contrary, the Yuan Dynasty technology is the seven-point drawing, three-point trimming, mainly because the Yuan Dynasty clay plasticity is strong, can be pulled very thin, so the upper part of the artifacts and the inner parts do not need to be repaired at all, but the lower part and circle of the need to do a simple repair.Therefore, the original objects of the mouth and neck are smooth lines, the appearance of round, do not fall knife marks.Modern copy of the drawing is very thick, not only to repair the upper half, and even repair the inner wall, therefore, the line is hard, regular more than enough, a lot of knife marks.

2: The old Yuanqing flowers were all burnt in firewood kilns, but now most imitation products are fired in gas kilns. These two processes are different, and the chemical and physical changes of the enamel are also different.Especially the formation process of the bubble in the glaze, it is different, the ancient wood kiln burning air bubbles to appear different sizes, bubble bright.The air bubbles in modern gas kilns are smaller and less transparent.This is only relative, also can’t rule out the modern fakery with wood kiln imitation artifacts, but also in the shape, decorative and other aspects of in-depth study, so as to judge.

3: Blue and white hair color is rich, elegant, blue and grey three kinds.Dense bright is to use imported Su Niebo green material, light elegant is imported materials and domestic materials mixed use.Some of the green flowers have black spots and are deep after firing.To the type of Yuanqing flowers are imported hemp hemp blue material, and the hemp blue material has a characteristic, is low manganese high iron, blue deep blue belt point purple, green slightly green.In Yuan Dynasty, the main ingredient of “Subrynitin” was cobalt oxide with a small amount of iron oxide.Under the action of high temperature, the iron oxide in “Suberazem” aggregates with each other in silicate liquid, forming dark crystal spots.Under the microscope, most of the brown spots of irregular sauce were deposited under the glaze.However, most modern imitations simply add ferric oxide powder to the production of domestic blue and white flowers. Under the action of high temperature, the iron oxide will float quickly to the glaze surface to form crystals.Slag-like spots were observed under microscope.


4: Most of them are wide and short circles.Generally, the inside cover does not apply glaze, but most of the inside and bottom see glaze spots.The body of the jar of Yuan Qing Hua is mostly four-section and three-jointed.There are also five paragraphs and four.The joints are located at the base, abdomen and neck.Paste the joint with mud, and the joint has a prominent protuberance.The mark of mud extrusion is visible at the junction.The inner wall of the vessel is usually light flint red without glaze.The bottom of the device is not applied with glaze, it is called rough bottom or sandy bottom, and on the rough bottom there is a red spot, commonly known as flint red most fakes red bottom into deep orange red, thin glaze, there is excessive faintness, the picture is dull and so on, as long as you look more, you can distinguish.

5: Most of the objects in Yuan Dynasty are made of hand-drawn blank or stripping molding process, and the obvious fingerprint and spiral lines are often shed on the inner wall of bottles, cans and other objects (see Figure 11). If no fingerprints and spiral lines are found on the inner wall of the objects, it is a low-grade imitation product produced by modern grouting molding technology.There are also people who understand Jingdezhen ceramic manufacturing process know that there are two kinds of knives used to repair billet, one is called “blade knife”, which is used to trim the inner wall of objects;One kind is called “plate knife”, is used to trim the external wall and the foot circle of the object.The appearance of the sword has a history of more than 2,000 years, while the sword was only found in the Kangxi period of the Qing Dynasty.In other words, the porcelain before Kangxi only repair the outer wall, not the inner wall, after the mid-period of Kangxi porcelain began to trim the inner wall.Some imitators don’t understand this, they just make it according to the illustrations and often paint the inside wall.So when you see the inner wall of Yuan Qing Hua, that’s a copy.

6: There is a direct relationship between the flatness of porcelain glaze and the method of glazing.As the Yuan Dynasty blue-and-white porcelain is dipped in glaze, poured glaze and brush glaze technology, it seems that the enamel is plump and thick, but lack of flatness.In particular, the use of glaze and brush glazing process of large objects, glaze often left “tear” and “brush mark” phenomenon.After Qing Dynasty, Jingdezhen generally used blowing glaze to apply glaze. The flatness of glaze surface was greatly improved. Modern electric air compressor was used instead of artificial blown glaze, which greatly improved production efficiency.The glaze surface is too smooth, smooth and thin, all are modern blown glaze products.

7: Yuan blue-and-white decoration dense, more layers, usually said to be “full painting”, seven to nine-layer decoration is common, sometimes up to a dozen layers.Paintings highlight buddhism, taoism and the history of the chinese nation.All are traditional Chinese traditional decorative patterns.The painting technique and artistic style of Zhengzheng Yuanqinghua are not only unprecedented, but also difficult to follow.Atmosphere, bold and unrestrained, unrestrained, elegant, showed the extraordinary ability of the painters.It can be seen that Yuan porcelain painters are not ordinary painters, many of whom were top painters at the time, leaving their kilns to paint.The immortal work of such an air is left behind.

The Yuan Qing Hua is very expensive because of its low heritage, so the market has always been full of fake products.It’s easier to read fake than to read it.If we look at the false, we can make a clear conclusion by grasping one of them.Look at the truth but to be cautious, comprehensive, as far as possible to grasp every detail, all possible points of doubt are excluded from the place to make a positive conclusion.
