How to identify the authenticity of Kangxi Lang Kiln red porcelain and how to identify Lang Kiln red porcelain?

Lang Kiln Red is the most colorful among China's precious copper red glazes. Its characteristics are: gorgeous color, bright red color, and a strong glassy luster. Because the glaze juice is thick and flows at high temperatures, the finished Langhong often shows a white body on the edge of the mouth, showing a spiral white line, commonly known as "Lamp Grass Edge".

The glaze juice at the bottom edge of Langyao Red flows down and condenses, almost black-red. In order to prevent the glaze from flowing down the bottom foot, the craftsman used a scraper to scrape a two-layer platform on the outside of the circle foot to prevent the glaze from flowing down. This is a unique technique in the production process of Langyao red porcelain. " known as.

The real Langhong is the official kiln or official and civilian kiln fired in the Kangxi Dynasty. Those after Kangxi were all imitated Lang kilns. Imitation of Kangxi Langhong was mainly made in the middle and late Qing Dynasty (Jia Dao and Guangxu) and the early Republic of China. How to identify the authenticity of Kangxi Lang Kiln red porcelain?

Any single-color red glaze with strong red color (the color becomes darker towards the bottom), strong glass texture, medium to large openings, and the fetal bones are exposed due to glaze detachment at the mouth of the vessel, are all Can be classified as Langhong category. The real Langhong is the official kiln or official and civilian kiln fired in the Kangxi Dynasty. Those after Kangxi were all imitated Lang kilns. Imitation of Kangxi Langhong was mainly made in the middle and late Qing Dynasty (Jia Dao and Guangxu) and the early Republic of China. How to identify the authenticity of Kangxi Lang Kiln red porcelain?

First Look at Red

The standard basis for identifying porcelain, such as patina, fetal bone, and fetal bottom, plays a certain role in the red glaze ware of the Langhong type in the Dangdai Dynasty, but it is not absolute. efficient. Through literature records and physical inspection, I propose that the first factor in identifying the authenticity and dating of Lang Hong is hair color, that is, the color of the red glaze. Next is the patina and glass texture, and finally the fetal bones.

So what is the standard hair color of Kangxi Langhong? The Langhong ware fired during the Kangxi dynasty had a very high proportion of high-temperature copper (so-called regardless of cost). Therefore, the result of firing is that under natural light, the red glaze on the surface of the ware appears deep purple-red, or Deep rose mauve color. For example, it is like the deep purple-red color in the center of the cross section of fresh pork liver after it is cut open (Friends who sell vegetables and cooks will naturally understand this). Under strong light irradiation, high-temperature copper completely absorbs the six colors of light (orange, yellow, green, cyan, indigo, and violet) and basically does not absorb red, giving the human eye a bright red texture. Therefore, Kangxi Langhong will have bright red hair color only when exposed to strong direct light, while under natural light, it will appear deep purple-red. Lang Hong, imitated after Kangxi, has this feature weaker and often appears bright red at first glance.

Second look at the glass texture and opening

Kangxi Langhong was fired regardless of cost, and the glaze was thick and agate was added to the ingredients. Therefore, the result of firing is The surface has a strong glass texture.

Under high-temperature firing, natural flakes are formed, the flakes are uneven, and the flakes are medium to large. The opening is not obvious, hidden under the glaze layer, and perfectly combined with high-temperature copper. Under a 40x magnifying glass, there are a small number of bubbles.

Third, look at the fetal bottom

Many people will have doubts. Isn’t the fetal bone very effective? Why look at the bottom of the tire first? The reason is that many of the imitators of Lang Hong who were burned after Kangxi used Kangxi's white fetuses to re-burn. Therefore, fetal bone is not the only valid feature. Kangxi Langhong's tire base has two types according to historical records and physical research. One is Pingguoqing, which is a characteristic of late Kangxi products, and the other is rice soup base, which is a characteristic of early Kangxi products. The third is sugar white glaze. In addition to the different glaze colors, the size of the slices is also different among the three. For example, the bottom of Pingguo Qing has large openings and is not obvious, while the bottom of rice soup has small openings. Compared with Pingguo Qing, the openings are more obvious. What is particularly important to emphasize here is that in addition to these three types of soles, there is also a type of soles, which are the soles of Pingguo green and red glaze, and there are also a small number of soles with mainly red glaze.

In addition, Kangxi Langhong has another characteristic that is often overlooked, that is, Kangxi Langhong is generally made of small and medium-sized vessels, with fewer large vessels. It cannot be said that there is none here, but less.

In the middle and late Qing Dynasty, the utensils imitating Kangxi Langhong were generally different from the Kangxi products in terms of red glaze color, glass texture, and opening. There were also major changes in the shape of the utensils. , such as the emergence of large-scale devices. Later, he imitated Lang Hong, and the works of the Guangxu Dynasty were the best.

Recently, I have seen that the market is flooded with a large number of new products. The uniqueness of these products is to use chemical ingredients to create a red color between deep purple and bright red, which I call " Demonic red". It has a glass texture and an opening. The types of utensils are also varied, including small ones, large ones, and huge ones. Collectors who like to collect Langhong need to be careful about this harmful item.

How to identify Langyao red porcelain?

Langyao red is a precious color-glazed porcelain created and fired after Lang Tingji, the governor of Jiangxi during the Kangxi period of the Qing Dynasty, went to Jingdezhen to serve as a pottery supervisor, imitating the Xuande "sacrifice to red" in the Ming Dynasty. However, in the collection market where blue and white are "popular", colored glazes "retreat to the second line". Some insiders said that color glazes, especially Langyao red, are simple and elegant. The market is not currently "hot" and the price is not high. It deserves the attention of working-class people with spare money and aesthetic ability. Today, let’s talk about how to identify Langyao red porcelain?

Characteristics of red glazed porcelain from the Kangxi period of the Qing Dynasty. "Lang Kiln Red" is as bright red as newly condensed ox blood. It is brilliant in color and vivid in red. It has the characteristics of "bright as a mirror, moist as jade, and red as blood". It is called a masterpiece among porcelains. The "cowpea red" shows an elegant and soft light peach color. Scattered dark red spots and green moss spots can also be seen on the glaze, which resemble the color of red cowpeas, so it is called "cowpea red".

Langyao red is one of the brighter copper red glazes. Its glaze surface is smooth and translucent, with a glass texture, open grains and ox hair patterns, and the glaze colors vary in shades. The darker color is bright red, with the characteristics of "bright as a mirror, as moist as jade, and as red as blood". Its glaze color is clear and rich, as scarlet as newly condensed cow's blood, and dazzling. The darker ones are black, the lighter ones are pink, and the lighter ones are dark brown. The glazes of Lang Kiln red wares come in three colors: beige, slightly cyan, and white, all of which are patterned. The glazes on the soles of Lang kiln red wares range from rice soup color to apple cyan color, both showing red spots. Sometimes there are also red glaze bottoms and white glaze bottoms.

The Lang Kiln red glaze wares also have the characteristics of the Kangxi Dynasty in other aspects. First, the fetal bones are white, dense and hard, and the exposed parts of the soles of the feet are red with flint; second, the edges of the feet are coated with powdery pink white glaze or pulp white glaze, and there are often broken bubbles; third, the pedicures include flat-cut, The flat-cut edges and corners are slightly rounded, rounded, or a two-story table-top style with a tapered inside and an outside; fourthly, there is a white line on the body of the vessel with red glaze and the foot except where the exposed tire is exposed; fifthly, the vessel has unique shapes such as Guanyin bottles and oil bottles. , Li-style bowls, etc. were all very popular shapes during the Kangxi period; sixth, most of them were without styles, with occasional blue and white "Fu", "Shou" and "Qing Dynasty" styles.

Due to the preciousness, rarity and high price of red-glazed porcelain from the Kangxi Lang Kiln, there were many imitators in later generations, some of which were so sophisticated that they could almost look like the real ones. But imitations cannot escape the characteristics of their times and are different from the genuine ones. Usually, most imitations of "Lang Kiln Red" were made during the Republic of China, and some imitated the various Lang Kiln wares of the Kangxi period by using the imitation Ge glaze wares of the Yongzheng Dynasty and adding green glaze or simply adding color.

Judging from the photos of the Langhong Tianqiu vase provided by readers, it has been identified as a new imitation by professionals. It mainly has six important flaws:

*Flaw 1: Glaze

Comparing the pictures of the "New Imitation Langhong Tianqiu Bottle" and the "Guangxu Langhong Guanyin Bottle", we can find obvious differences between the two. The glaze at the mouth of the genuine bottle is off-white, while the fake one is pure white; although the two The inner wall of the bottle is as smooth as a mirror, but the genuine one has a precipitated luster, while the fake one has a bright red color, which is very dazzling. It should be the effect of the counterfeiter applying glass glaze on the bottle body. The real thing can also be seen from the "Kangxi Langhong Incense Burner" The Langhong color is thick and heavy, without any sense of frivolity; at the "junction" between the white glaze and the red glaze at the mouth of the bottle, you can see that the red glaze of the authentic product has a drooping phenomenon, showing a natural flow, while the fake product has obvious It's very unnatural to sweep the red glaze on.

different. The opening of the imitation bottle is very small, giving the impression of broken glass, but there is no opening on the inner wall of the bottle, only pure white glaze; in the authentic bottle, the inner and outer walls of the Guanyin bottle have openings, and the inner wall of the incense burner is completely open. The slices open naturally and are in the shape of "well".

*Flaw 3: Bottom

Comparing the "Guangxu Langhong Guanyin Vase", "Kangxi Langhong Plate" and "Kangxi Langhong Incense Burner", we can find how many pieces of Langhong ware are at the bottom? The same thing: the glazed part is "rice soup white" and has slices. The bottom of the incense burner is the most special. Only a small circle in the middle is the glazed part, and the rest is exposed. The bottom of the "New Imitation Lang Hong Tianqiu Bottle" is completely covered with pure white glaze, without cracks, and it is obviously "glossy".

, it can be judged that the counterfeiter polished the ring feet to create the "illusion" that the red glaze only flows to the bottom of the object, which is very regular.

From the "Guangxu Langhong Guanyin Bottle", we can see the important characteristics of Langhong's utensils - the "light grass edge" bottom - the ring foot is uneven, and the red glaze naturally "borders" the ring foot slightly. This is because the circle of feet was once scraped by craftsmen with a knife to "fix the feet", which is very natural.

*Flaw five: identification

From the "new imitation Lang Hongtian ball vase", we can see the obvious identification "made in Jingdezhen". But in fact, Langhong's utensils generally have no designation, let alone the designation of "Made in Jingdezhen". Several genuine items mentioned in the article are unidentified. From this identification, it can be inferred that the fake was produced in the 1980s and 1990s.

In fact, the weight of the real product is very even up and down, and the center of gravity will not drop.
