Artifacts identification jarCultural relic identification of terrines was the work of using traditional methods or modern science and technology to analyze and identify the authenticity, texture, use, and value of terrines.
From the perspective of the shape of the terrines, for example, the terrines of different dynasties had different characteristics. The terrines of the Sui and Tang Dynasties might have simple shapes, while the terrines of the Western Jin Dynasty might have their own styles such as the pot. From the aspect of the soil, one had to check its texture, color, and other characteristics. Some earthen pots were affected by the natural environment of the underground moisture, and the color formed would invade the fetal bone, and the surface corrosion and peeling would form a thick ooze. These were all helpful in determining the authenticity of the pot. Judging from the surface of the soil, the earthen jars of different dynasties and regions had different characteristics.
To judge the value, one must first look at the age and patterns. Plain clay pots were generally more valuable before the Qin and Han Dynasties. The patterns with dragon patterns, taotie patterns, god patterns, chariot patterns, banquet music, animal faces, and other patterns were of higher grade and value. The value of cloth patterns, rope patterns, mat patterns, and regular geometric patterns was lower. At the same time, the size and integrity of the pot, as well as the thickness of the pottery, also affected the price.

Identification of Jiangxi Jade ArtifactsJiangxi jade identification mainly has the following aspects:
- ** Appearance characteristics **: The color is generally green, white, yellow, etc. The texture is fine and the luster is soft. There were often natural patterns and impurities on the surface, which could be used as a basis for identifying authenticity.
- ** Internal structure **: The internal structure is relatively compact and uniform. Under the microscope, there were many tiny grain-like structures. The finer the grain, the better the texture of the jade.
- ** Hardness Test **: Hardness is an important indicator for identifying jade. The hardness of Jiangxi jade is relatively high, generally between 6 - 7. It could be tested by scratching against glass, steel knives, and other items. If the jade could leave scratches on these items, it might be jade.

Restoration of Rare ArtifactsIn the field of cultural relic restoration, there were many examples of rare cultural relics being restored. For example, the bronze tree unearthed from the No. 2 pit of Sanxing Dui was the largest bronze artifact unearthed in Sanxing Dui, with a height of 3.96 meters. Due to the age and the fire, the base, branches, trunks, and divine birds were almost all "shattered" when they were unearthed, with as many as 2479 pieces. After sorting out the fragments, the archaeologists spent a full 10 years restoring them.
The painted terracotta warriors and horses unearthed from the first and second pits of the Qin Emperor's mausoleum were originally painted with bright colors. However, because the main component of the bottom layer of the painted terracotta warriors was raw lacquer, the production process and the violent reaction to environmental changes caused them to curl up and fall off quickly when they were unearthed, making it extremely difficult to preserve. Through the research and development of new materials and specific reinforcement techniques, these painted terracotta figures could be made to show their true colors.
Modern technology also played a big role in the preservation and handwriting identification of the medical slips from the Han Dynasty tomb in Laoguan Mountain, Chengdu. These examples demonstrate the challenges faced in the restoration of rare cultural relics and the techniques and methods used.

Ancient Jade Artifacts: Chronology and IdentificationThe dating and identification of ancient jade articles could be started from the following aspects:
** 1. Craftsmanship Traces **
1. ** Tool Traces **
- There were obvious differences between the ancient manual and semi-automatic weight machine technology and the modern electric weight machine technology. For jade from the Neoliths to the Qing Dynasty, the polishing marks could be observed with a magnifying glass of 10 - 50 times. Manual weights had been invented in the late Neoliths, which were polished with jade sand, animal skin wheel weights, cotton or linen wheel weights, etc. In modern times, the mechanical hole wall of jade processed with electric weights was relatively regular, leaving fine and even spiral patterns and not smooth enough. There may be slag at the edge of the hole.
- Most of the holes in the Neoliths were trumpet shaped, and the long holes were mostly made by drilling in pairs. The holes were medium-thin and large at both ends. Spiral patterns of different thickness could be seen on the hole walls, and the surface was smooth. After the invention of ironware in the Warring States Period, the holes were more regular, but the spiral patterns on the hole wall were not as fine and equal as the mechanical hole wall, and the edges of the holes and lines appeared to be slag.
2. ** Polishing marks **
- Jade articles polished during the Neoliths and the Shang and Zhou Dynasties could be observed with a magnifying glass of 10 or 20 times. Fine concave lines of uneven thickness and different directions could be observed. Occasionally, there would be messy fine concave lines and a sense of layering. It was different from the fine, equal, and relatively parallel fine concave lines polished by mechanical polishing or imitating the ancient method. Most of the high-quality jades were flat, even and clean. The dent marks of the vertical weight could be found on the electric weight tools.
** 2. Oxidation Identification **
1. ** Range of application and tools **
- It is suitable for ancient jade unearthed from the Neoliths to the Qing Dynasty. You can use a magnifying glass of 10 - 50 times and a strong flashlight to identify it by observing the surface of the plane under the light.
2. ** Oxidation and its characteristics **
- There were two kinds of situations where the oxygen was either corroded into chicken bones or seriously vaporized into powder. From a mineral point of view, the density of the jade was different and mixed with other substances. Under the long-term chemical effect, the weak parts of the texture, especially the surface, would be corroded to form small holes, or the surface would be corroded to form white spots. The degree of severity was different, and there was a sense of layering and depth. The weak parts of jade are usually heavily oxided. The surface of the burnt fake jade was a thin layer of powder. There was no depth or layering. Under the strong light, the jade was pure and transparent. The thickness of the rust was very thin and the depth of each part was the same. The natural rust depth was light and heavy. Usually, the sharp corners and edges were heavier, and the light of the heavy rust could not shine through. However, it should be noted that some forgers used natural jade materials to make artifacts. It was necessary to see whether the corrosion was universal from the traces of processing.
** 3. Corrosion Appraisal **
1. ** Range of application and tools **
- It was suitable for corroded ancient jade. Use a 10 - 50x magnifying glass and a strong flashlight to observe the characteristics.
2. ** Corrosion characteristic **
- There were usually erosive holes and plaque. Some of the erosive holes had a large abdomen, and under a magnifying glass, the bright crystals formed by chemical changes in the holes could be observed. This was a feature that was difficult to forge at present. The surface of jade artifacts that were forged by acid corrosion usually had a large area of uneven corrosion, with obvious corrosion holes and spots. The corrosion holes were often large on the outside and small on the inside. There were no crystals and they were mottled.
** 4. Judging from the material of the jade ware **
1. ** Jade characteristics of different dynasties **
- During the Hongshan culture period, most of the jade articles were mainly Xiuyan jade. After the Shang Dynasty, the jade materials used in ancient jade articles were mostly Hetian jade (Hetian jade in a narrow sense, produced in Xinjiang). However, in ancient times, a considerable part of the jade materials belonged to "local jade" such as Xiuyan jade, Nanyang jade, Lantian jade, etc. During the Han Dynasty, most of the jades were made of Hetian jade. Different broad sense Hetian jade (such as Russian jade, Qinghai jade, Korean jade, Canada jade, etc.) began to be mined and used in the 1980s and 1990s. If the raw material of the jade was these broad sense Hetian jade, it could be judged that it was not an antique.
2. ** The principle of good materials and good work **
- Most of the exquisite ancient jade was made of Hetian jade in Xinjiang because of its outstanding quality and rarity.
** 5. Judging from the appearance **
- Ancient jade articles of different historical periods had different shapes and characteristics, such as the jade cong of Liangzhu culture, the jade wall of the Warring States period, the jade flying characters of the Tang Dynasty, the jade belt hook of the Song Dynasty, the Zigang plate of the Ming Dynasty, and the jade mountain of the Qing Dynasty.

The Value of Bronze ArtifactsBronze relics had many values:
1. [Historical value: As witnesses of history, bronzes retain traces of different historical periods.] From the bronzes of the Xia, Shang, and Western Zhou Dynasties, to the gold and silver wares of the Spring and Autumn and Warring States Period, to the bronze mirrors and copper coins of the Han and Tang Dynasties, each of them carried a historical memory. By studying bronzes, one could understand the development of history and accurately interpret the truth of history.
2. ** Cultural value **: Bronze ware is an important part of Chinese culture, which condenses the wisdom and creativity of the ancients. From its shape, decorative patterns, inscriptions and other aspects, we can get a glimpse of the aesthetic concept, value orientation and humane spirit of the ancients, which is of great significance for understanding Chinese culture and inheriting Chinese civilization.
3. ** Art Value **: As a work of art, bronzes display a unique artistic charm. Whether it was exquisite bronze ware, unique brass ware, or modern copper crafts, they all condensed the painstaking efforts and skills of the craftsmen. They had different shapes, exquisite patterns, unique craftsmanship, and high artistic value.
4. [Collection value: Due to the long history of bronzes, the scarcity of bronzes, and the difficulty of preservation, bronzes are favored by collectors.] Some of the precious bronzes were regarded as national treasures. For collectors, owning a precious bronze was not only a display of taste and strength, but also a symbol of wealth.
5. ** Technology value **: With the continuous development of science and technology, the research on the composition and craftsmanship of bronzes has become increasingly in-depth. Through the scientific and technological analysis of bronzeware, one could understand the ancient smelting technology, casting technology and other knowledge, and provide reference and enlightenment for the development of modern science and technology.

Increase the value of cultural relics identificationIn order to increase the value of cultural relics identification, the following aspects could be started:
** 1. Appraisers **
1. ** Increase professionalism **
- Appraisers should have a deep academic foundation, such as in-depth research on the shape, material, age, and technological characteristics of cultural relics from different historical periods. For example, in Jiujiang City's cultural relics public welfare appraisal activity, experts relied on their own professional knowledge to analyze the collection from many aspects. This was the basis for accurate appraisal.
- He had accumulated a wealth of practical experience and improved his ability to distinguish the authenticity of cultural relics through contact with a large number of authentic and fake goods.
2. ** Maintain professional ethics **
- Appraisers must maintain a fair and objective attitude and avoid entering into improper "agreements" with collectors or other interested parties. For example, in the "gold jade pendant" appraisal incident, the unprofessional behavior of some experts seriously affected the value of the appraisal, so the appraisers should stick to the bottom line of professional ethics to ensure the authenticity of the appraisal results.
** 2. Appraisal Techniques **
1. ** The application of traditional technology **
- Proficient in traditional identification tools and methods, such as using a magnifying glass to observe the detailed texture of cultural relics, using a flashlight to examine the internal structure of cultural relics, etc., to judge the authenticity and value of cultural relics from the craftsmanship and texture.
2. ** Combination of modern technology **
- The introduction of high-tech instruments to assist in the identification, such as the use of spectral analysis instruments to determine the material composition of cultural relics, the use of carbon- 14 dating methods to determine the age range of cultural relics, etc., to improve the accuracy and scientific nature of the identification.
** 3. Appraisal process **
1. ** Strictly **
- Establishing a strict appraisal process to ensure that every step of the appraisal process had rules to follow. For example, when Zibo City Museum carried out the identification of cultural relics, it strictly followed the laws and regulations and the work process, which helped to improve the accuracy and authority of the identification.
2. ** Translucency **
- It would make the identification process transparent so that Tibetan friends or the public could understand the basic methods and basis of the identification and increase the credibility of the identification results.
** 4. Public Awareness **
1. ** Universal Education **
- By organizing cultural relic appraisal public welfare activities, such as those in Zibo, Jiujiang, and other places, cultural relics knowledge could be popularized to the public, and the public's ability to appreciate cultural relics could be improved. At the same time, the public could better understand the value and significance of appraisal work.
- He would guide the public to establish the correct concept of collection and avoid blindly following the trend of collecting. This would make the entire collection market more rational and indirectly increase the value of cultural relics appraisal.

The Value of Jade Artifacts in JinJudging from the jade artifacts unearthed from the tombs of marquises of the Western Zhou Dynasty, they were of great value in many aspects.
In terms of artistic value, these jade articles were made of exquisite materials, exquisite craftsmanship, unique shapes, and smooth patterns. The jade materials were varied, such as sapphire, white jade, jasper, black jade, agate, turquoise, malachite, beads, etc. The jade materials of different colors reflected the beautiful scene of colorful flowing light. The jade-cutter used his skills to carve fish, cattle, deer, rabbits, turtles, cicadas, and other unique shapes. In terms of decorative patterns, it was popular to use the double Yin lines carved on the inside to express the dragon, phoenix, human and other decorative patterns, creating a smooth and agile effect, showing a very high artistic level.
In terms of cultural value, these jades fully reflected the style of the Zhou Dynasty, which was "learned from the second generation" and "refined". It was a symbol of the ritual and music civilization of the Western Zhou Dynasty. They interpreted the ritual and music civilization of the Western Zhou Dynasty from a certain angle, which was featured by "culture". They could allow people to understand the cultural style and etiquette system of the Western Zhou Dynasty through these jade articles.
In terms of archaeological value, the discovery and excavation of the Jin Marquis's tomb was one of the most important achievements of China archaeology, and the dazzling array of jade articles was the most important and eye-catching component. It was the most powerful proof that the ancient China jade culture had developed for thousands of years and reached its peak in the Western Zhou Dynasty. It played an irreplaceable role in the study of the development of ancient jade culture.

The Identification Method of Jade Artifacts of Ming Dynasty in Henan ProvinceThe following are some methods to identify jade articles of the Ming Dynasty in Henan:
** 1. Material **
1. ** Quality Identification **
- One had to observe the texture of the jade. Although jade generally had a hardness of 6 on the Mohs scale, different jade materials had their own characteristics. The real Ming Dynasty jade had its natural characteristics, while the fake might have differences in the texture and luster.
- For example, if the Ming Dynasty jade pendant was authentic, it might be made of "milky white" or "glutinous ice white" jade. If it was fake, it was usually made of mineral materials.
2. ** Color identification **
- The color of the jade in the Ming Dynasty was due to the long-term burial of the jade in the closed tomb or soil. Due to the influence of the soil, ground temperature, ground humidity, and the materials in the pit, the jade itself had a qualitative change in its molecules, the structural water was lost, the pores became larger, and various colored impurities in the soil invaded the jade.
- Observing under a magnifying glass, the translucent parts would be mixed with dark dots or silk-like, distributed naturally. The color of the real thing was formed naturally, while the color of the fake was often unnatural.
- For example, the theory of weathering mentioned that the whiteness of Ming Dynasty jade articles was mainly due to the loosening of the mineral structure after being eroded. The formation of different colors was related to the local soil and other environmental factors. The soil and other environmental factors in Henan would affect the formation characteristics of the jade color of the Ming Dynasty. The genuine color should conform to the local environmental characteristics.
3. ** Appearance identification **
- The dipping method could be used to identify the jade. Put the jade into water or dip it in water. When you rub it with water, you will feel a sticky feeling. It will be like this every time until it is completely played. When soaked in water, a layer of sticky substance would be released from the jade surface, which was the so-called pulp. If there was no such phenomenon or if the phenomenon was not obvious and unnatural, it might be a counterfeit.
** 2. Styling and decoration **
1. ** Appearance identification **
- The jade articles excavated by scientific archaeology should be used as the basis for the identification and identification, and combined with the ancient literature records and the jade articles handed down from generation to generation, the law of the development of the model of typical works should be analyzed. The jade articles of the Ming Dynasty in Henan should conform to the overall style of the time. If the style was completely inconsistent with the style of the Ming Dynasty, it might be a counterfeit.
2. ** Pattern identification **
- Although the patterns on Ming Dynasty jade ware were not complicated and could be easily copied, one could not think that a Ming Dynasty jade ware with a large number of the same patterns was a counterfeit. At the same time, he also had to consider the possibility that unknown new jade ornaments from the Ming Dynasty might be unearthed. However, if the decorative style was very different from the typical decorative patterns of the Ming Dynasty, or if the carving process of the decorative patterns was rough and unnatural, such as the lines were not smooth, it might be a fake.
** 3. Processing technology **
1. ** Tool Marks Identification **
- From the stone processing tools that were mainly ground before the Xia Dynasty, to the copper processing tools that appeared in the early Shang Dynasty, to the iron processing tools that appeared in the late Spring and Autumn Period, the marks left on the surface of the Ming Dynasty jade ware were different due to the different processing tools in each period. Since the reversing machine determined that each trace had a certain regularity, it was necessary to master this regularity to identify it. For example, the processing traces on the authentic Ming Dynasty jade ware should conform to the characteristics of the craftsmanship at that time, while the counterfeit may have irregular processing traces or not conform to the craftsmanship at that time.
2. ** Corrosion Appraisal (For unearthed Ming Dynasty jade artifacts)**
- You can use a magnifying glass of 10 - 50 times and a powerful flashlight to observe the characteristics of the corroded Ming Dynasty jade. However, this method had its limitations. It was not suitable for Ming Dynasty jade articles (handed down from generation to generation) that did not corrode. If it was a Ming Dynasty jade artifact unearthed in Henan and there was corrosion, this method could be used to identify its authenticity.

China Jade Artifacts with Strong Historical ValueChina jade had a strong historical value, and its development had gone through many stages.
In the early Neoliths, jade was separated from stone and entered the divine jade period. At this time, jade was given the attribute of communicating with heaven, earth, people, and gods. It was both a precious treasure and a reflection of status. Most of them were owned by primitive tribal leaders and wizards. There were many kinds of jade wares in Liangzhu culture, such as jade cong, jade Bi, jade axe, etc. The level of embossed decoration and line carving was very high. The carving of jade cong and the pattern of feathered human on the animal face could reflect the level of jade carving at that time. Moreover, the jade wares in this period were regarded as tools to communicate with the gods of heaven and earth. Besides worshipping heaven and earth, burying corpses, they could also ward off evil spirits and symbolize power and wealth.
From the Shang and Zhou Dynasties to the Han Dynasty, it entered the Wang Yu period. During the Shang and Zhou Dynasties, with the development of private ownership and hierarchy, jade articles were religious and also more prominent in wealth and status. Ordinary people had no right to use them. During the Eastern Zhou Dynasty, the value of jade was at its peak, like the Heshi jade. The King of Qin was willing to exchange it for fifteen cities. Jade articles of the Han Dynasty were expensive and had distinct grades. For example, the jade clothes and jade ornaments in the tombs of the Han Dynasty were not allowed to be used by the nobles. The peak of jade carvings in the Han Dynasty was in terms of original carvings. Its artistry, difficulty of carving technology, and material requirements were extremely high. For example, the golden jade clothes were composed of more than 2500 pieces of jade, which took up to ten years to make, showing the prominent position of the tomb owner.
Jade articles in the Tang Dynasty became the consumer goods of the upper-class society. Although some jade articles were restricted by the imperial court, jade cups and jade pendants were not regulated and became daily necessities. From the Song Dynasty onwards, the "ritual" nature of jade articles was greatly reduced, and the "fun" taste increased greatly. It was closer to real life. The practical decorative jade of Song, Liao and Jin jade articles occupied an important position.
Ancient jade was a scarce resource, rich in historical and cultural information. China ancient jade was cherished by foreign museum and senior collectors. In short, China jade had a unique cultural meaning and value in each historical period, and it was an important part of China cultural heritage.

The Value of Jade Artifacts in the Warring States PeriodThe evaluation of the value of the Warring States jade was the result of many factors.
In terms of material quality, different jade qualities would have a direct impact on the price. In terms of craftsmanship, exquisite carving skills could often increase its value. If the process was relatively simple, such as ordinary jade pendants, jade walls, jade congs, etc., the production process and materials were more common, and the price was usually between thousands of yuan to tens of thousands of yuan. However, some jade articles with complex processes and high artistic value, such as large jade walls, jade congs, etc., could be sold for hundreds of thousands or even millions of yuan due to their historical value, artistic value, and scarcity. For example, the White Jade Dragon Token of the Warring States Period was worth more than 6 million.
In addition, the model was also one of the factors that affected the value. The price of different models in the market was quite different. Moreover, the preservation condition of the Warring States jade and the market demand were also key factors that affected its price. However, a peerless treasure like the Heshi jade could be worth even more, estimated to be at least 680 million.
