From the blue and white porcelain to the Yuan dynasty, it has developed into a more mature period. Jingdezhen's rare and precious rare items of blue-and-white porcelain have attracted more and more attention. Yuan blue and white glazes are translucent and bright, white and slightly green, usually blue and white, with a small amount of white or blueish porcelain, thick fetal bones, and unstable blue-and-white hair color. Imported materials and domestic materials are different from the two materials, some blue and white, and some color flash. I believe that the identification of a blue and white porcelain should grasp the following points:
First, watch the shape. The shape of bottles, jars, and the like must be carefully examined for its rim, neck, shoulders, abdomen, and sole, to see if there are features of the Yuan Dynasty, but also to identify the shape of the carcass weight, the shape of the device Comprehensive analysis. In the Yuan Dynasty, the general shape of the carcass, such as bottles and cans, was thick and hard.
Second, look at the glaze. The blue and white glaze of the Yuan blue and white porcelain is slightly bright, shiny and translucent, but blue and white porcelain is also white or blue. In the early Yuan Dynasty (Yanyu Period), blue and white porcelain glazes such as bottles and cans were used to make transparent white glazes, touch the glazed surface like a sense of glutinous rice, and sometimes the glaze had a matte color, and the green color was slightly blue-gray. Visibly brownish, look closely at the white spots on the glazed glazed surface. A small number of body glazes can be seen on the fine crumb layer. Oblique light sees the glaze slightly revealing irregular glaze wire stripes. The white glazes, the shroud glazes, and the white-glazed blue-and-white porcelains that began firing in the middle of the year are mostly white-white, slightly bluish green, and are white-glazed glazes with a transparent glassy texture.
Third, look at blue and white flowers. The blue-and-white porcelain color is not stable, the blue-and-white color faints, and the blue-and-white color is divided into two types: one is rich in color and thick in color; the other is called “black beak”; This is a sense of unevenness, which is the use of imported "Su Mu Bo Green" material unique coloring effect; the other is made of domestic materials, domestic material blue and green hair is blue in the pan, some color is blue and blue bias Ash or blue and blue hair flashes gray. The peony pattern of Yanyou's blue-flowering hair color is deep in the cloud of the fetus, like a lurking luster on the fetus. The blue-and-white floats and the glazed surface are closely attached. The halo and blue-flowering are deep-fried. The floating blue-and-white glaze has thick black threads and dots. The blue pattern is decorated closely to the glaze and is slightly concave. This is also the basic point of identifying the Jingdezhen Yuanqinghua and Porcelain.
Fourth, look ornamentation. The decoration of the Yuan Dynasty blue and white porcelain can be divided into two categories. One is the use of imported materials painting decoration, with full composition, rich layers, neat painting features. For example, the pattern of the large plate is composed of three to five layers of dense patterns. The patterns of the bottles and cans are composed of three to eight patterns. The pattern is characterized by the coordination of the guests and the complexity of the subjects. The motifs are varied and varied. The story is composed of tangled flowers, algae, lotus ponds, double phoenix flowers, opening and closing branches, bamboo and stone flowers, fruits and other patterns. The floral pattern has the characteristics of large flowers and large leaves. Among them, the leaf petals of the entangled lotus are painted as gourd-shaped. The border of peony ornament is painted in a white beaded shape, the auxiliary variant lotus petals are often spaced, and the interior trim has blue-and-white features. Another kind of blue-and-white painting is made with domestic materials. Its pattern has the characteristics of smooth and unrestrained, pattern composition is relatively simple, and the drawing is relatively coarse, and various floral patterns are more common.
Fifth, look inside. The blue and white porcelain vases and cans are not glazed on the inner wall, sand on the inner wall, and the body is generally made by sectioning and bonding. Therefore, the abdomen and the bottom of the tank are often left with obvious fetal traces. There is no trimming in the connection between the inside of the plum bottle and the shoulder, so there is a rough feeling. The inner wall fetal rims are mostly fetal rims with a bulge ranging from 1 to 2 mm. The thickness is irregular and the hand feels smooth and delicate. The sand on the inner wall of the bottle is slightly yellowish. The inner wall of the inner wall of the sand and the inner wall of the small granules are clearly visible. The upper part of the abdomen is generally not repaired. The lower abdomen to the bottom has a lot of trim marks. The inner wall of the bottle is clearly visible. . The strong light obliquely looks at the inner wall of the dizzy sand eyes and flashes a starlight spot, emitting a light, also known as a cloudy sunshine spot.
Sixth, look at the bottom. The bottom of the Yuan Dynasty blue-and-white porcelain vases and cans were mostly indented and foot-like. The soles of the feet were thick and small, and a few of the feet were laterally chamfered. The dug feet were shallow and deep, mostly dug shallow feet. In the case of bowls and bowls, most of the feet are chamfered on the outside. However, whether they are scorpions or circulators, the ring feet are more regular and irregular. Bottles, jars and the like, some of which have a tight foot sand, and some slightly loose sense of fetal quality, small trachoma and black paste pits are clearly visible, and some of the plantar micro-raised chicken heart-like. Bottles and cans have swirling marks on the soles of the feet. They are red and flaming red, and some of the small stones are visible at the bottom of the ring and on the soles of the feet. There are thin black enamel spots and natural marks. Explosive.
Seven, see color and bubbles. The color of the blue and white flowers is also very important. The outer feet of the bottles and cans are generally thicker with aquamarine showing water-green color, but also have a duck egg blue color. The body glazed tends to appear blue-white, light blue, or uneven. Yellowish brown and other colors. In the early Yuan Dynasty, the blue-and-white porcelain bottles and cans were obviously colored, and the color was different from the dryness, humidity, temperature, and seasonal changes in the air. In the early and middle (Yanchao period) of the Yuan Dynasty, slight sweating was sometimes observed on the glaze of blue-and-white porcelain glazes, such as bottles and cans. Generally, it was a hot weather season. There were blue and white glazes in the early and middle dynasties of the Yuan Dynasty, and most of the blue and white glazes on the Shufu glaze. There is no air bubble. There will be bubbles on the blue and white porcelain, white glaze, and egg white glaze that have been fired from the middle of the year, but there will be two types of bubbles, small bubbles, and most of the glazed porcelain of the blue and white porcelain will look dry and transparent.
