Blue and white porcelain, also known as white blue and white porcelain, is made from cobalt oxide containing cobalt ore, which is relatively well-known in China. If fake blue and white porcelain are easy to appear on the market, then it needs to be identified. What are the methods of appraising blue and white porcelain ? The following small series briefly introduces the identification of blue and white porcelain .

First, the device type:

The shape of ancient porcelain is changing with the needs of the development of the times and is an important basis for the generation. Some devices have inherited the legacy of the past. For example: plum bottles, Yuhuchun, garlic bottles, etc. are popular in the Song Dynasty. The garlic kettles have been used since the Warring States period. There are many types of blue and white blue and white flowers, the vast majority of which are living utilities, some of which are dedicated for offerings, and a small amount for decorators.

There is no large device in the Song Dynasty. In contrast, the Yuan porcelain is thick, large, and powerful. However, there are small bowls that are refined beyond the imagination into thin shells and lighted ones. As the ancient porcelain was taught by mentors, passed down from generation to generation, and focused on the aesthetics of the device, the proportions were harmonious, round and smooth, with refinement, gas, and spirit.

Defective product performance: The overall feeling is not harmonious, irregular, rigid, lack of craftiness, and even some nondescript. The slipping shoulders are not rounded, the belly belly is not streamlined, and the articles with lids are not well-matched and the gap is too large. The head of the beast decorated on the tank is not deadly, and the ear of the bottle and the phoenix on the pot do not have the vitality.

Second, decoration:

The decoration of the Yuan Blue and White Flower is relatively dense, and can be up to about ten layers. The characteristics of the Dragon Pattern are obviously different from those in the past, showing domineering, publicity, open-mouthed eyes, developed tendons, claws like a knife, and despise everything.

The stylized performance of the fakes: Most of them can be painted according to the original originals, but because they are imitations, they are bound to be rigid and rigid. Animals are not vivid, characters are not vivid, some are left blank, loose leaves are not compact, and leaves are not natural gourd-shaped. Most of the ocean-weave patterns are shaped. The instrument type and ornamentation are the important basis for the period of generation. Different periods have the characteristics of the era of the historical period. If the modern painter has created the ornament, it is not in conformity with the genuine product. Exposure is a fake product. The most important point is that the ancients were descendants who inherited family culture for several generations. They have profound backgrounds, wonderful pens and flowers. The decoration of the fake product can only be said to be similar in terms of plots and paintings, but it lacks the connotation of genuine devices and has no background, and it is impossible to draw the verve of authentic products.

Third, the glaze:

If you compare a porcelain to a human being, the fetus is the skeleton of the human being. The glaze is like the skin of human beings, and the white and smooth skin is liked by the world. The glazed part of the Yuan blue and white flower is partly greenish and mostly egg white, and the glazed part is water-green. Some glazes add glaze, so they are characterized by hypertrophy and dignity. Some artifacts have slight orange glaze and shrinkage on the surface. Before the Republic of China, ancient porcelain glazes were handed down. From a macro point of view, they all have a calm, old, glazed, jadey texture and are soft to use. There are different degrees of wear scars in micro-viewing, and the corners and bulges will have historical marks. The precious artifacts, as long as you often appreciate to play, will certainly leave a memory of time.

The glazed appearance of the fake product: Since the imitation of the blue and white flower is a new one, the glazed flame has not been dispersed yet, and the impression of impetuousness and inflexibility is not felt. There is no sense of stability and oldness in the real thing. Some glazes are white, and the glaze is too green. There is no trace of natural use on the overall glaze. The conditions of modern kilns are good, there is no past glaze due to kiln leakage, resulting in glaze shrinking glaze. The shrinking glaze (also known as blinking) seen on the imitation utensil table is an artificial eye, which is unnatural. Some fakes have large pseudo-dip impregnated with earthenware glazes, and some glazes have a lot of floating-like imitation sea fishing porcelain. Now the replicas use electricity and kilns. The bubbles are relatively uniform and there is no sense of depth. Some imitations artificially create old violence on the rim, but at the leaking glaze, thin layers of glaze can be seen.

Fourth, the fetal quality:

The majority of fetal bones of the blue and white flower are kaolin clay, which is called a binary formulation. As early as the Five Dynasties, the formula was invented in the Fanchang Kiln and the Qing Dynasty in the Northern Song Dynasty. Because of the different kiln mouths that produce blue and white, the characteristics of the fetus are different. Formulated tires have a certain degree of strength and flexibility, can control high temperature deformation to a large extent, and ensure the molding rate of large-sized articles. The large cans of the Yuan Blue Jasmine have a hundred pounds, large plates, and large bowls that are shocking to people. Macroscopically, there is a feeling of softness in the bottom of the tire, and there is no firm porcelain in the late Ming period. Most of the bottoms have trachoma and the bottom is not smooth. The small breasts left behind by the utensils are the characteristics of some craftsmen.

The performance of the fake fetal material: The fetal mud of some defective products is mechanically agitated, the density is higher than that of the real device, and the femur is hard. True, false compared to the same size size of the device, most of the fake products than the real thing. At the end of the device, there is no feeling that the old tire is air-dried and smooth. The fake Flint Red is more rigid, mostly artificially sprayed, brushed with iron oxide, and has no transition. Because it is a new work, there is no sense of layering at the bottom of the artifacts, and there is no sense of oiliness in the real thing. Some of the fakes had no knife marks, some of them were visible, but they could be seen as clumsy. They could not find the old-fashioned craftsmanship of the ancients.

Five, color materials:

Most of the cobalt oxide used in the Yuan Blue and White painting is imported material, which is used with ancient Persian trade porcelain, silk, tea, exchange or purchase. There are currently three kinds of translations: Su Bo mud blue, Suni Bo green, and Su Ma from Qing. Imported materials have the characteristics of high-iron and low-manganese, irregular black-brown patches or tin spots, concavity and convexity, and halo, sinking, gathering filaments, nets and beads. Some rogues, there are pan-purple. The blue-haired hair color has a verdant, dark and varied effect, and some can produce the art of ink painting.

Defective cobalt material: It should be said that the imitation of imported materials now looks like a macro, but there are no natural and natural gathering threads, beads, etc., and some beads are artificially painted. Iron spots, tin light floating surface, there is no genuine iron spots like the feeling of growing out from the fetus bone, but also no sense of transitional contrast. The most important point is that because it is a new painting on a green tire, there is no historical precipitation, and the blue flower floats on the surface of the device and does not sink under the glaze.
