Explain the microscopic identification of ancient ceramics - Database & Sql Blog Articles

The so-called microscopic identification is to use microscopic equipment to observe the aging degree of the ceramic glaze, so as to verify the authenticity of the porcelain. The microscopic identification method is mainly based on bubble identification, and also includes trace identification, opening identification, erosion identification and the like. The principle of microscopic identification is: ancient ceramics have experienced hundreds of years or even thousands of years of history. Whether in the soil, in the water or in the world (in the air), the glaze will produce different degrees of aging. It will be reflected in some characteristics of the glaze, and the microscopic technique can be used to observe and understand these features, and the artifacts can be authenticated.

The background of microscopic identification, in the past, microscopic technology is not popular enough, except for the laboratory, the average person can not use the microscopic equipment to identify ancient porcelain. With the advancement of technology, handheld portable microscopes are now available on the market.

In addition, the traditional experience and eyesight identification methods are getting more and more limited, and the new scientific identification method market is coming to the fore. Therefore, the technical equipment and market requirements for microscopic identification have matured, and microscopic identification for practical identification has no obstacles in terms of technology and equipment.

First, the spectacle under the microscopic horizon

Let’s look at a few

Under the microscope, the microscopic picture of the celadon glaze (the picture was color-treated).

Water drop flower

Look at the state of the bubbles in this picture, like a splash of water falling on the surface of the water?

Shoal water map

This glazed and bubble state, like the turbulent water on a shoal or riverbed shoal?

Urban street map

This glazed and air bubble phenomenon looks like a traffic map that is not like a city street?

Crystal flower bead diagram

This glazed and bubble phenomenon, like a crystal flower like some minerals wrapped in a pearl?

Stars holding the moon

This said that the stars do not seem to be very image, it is more like a small star (

) Holding a big star.

If you don't see these pictures, people will think that there will be such rich content under the seemingly smooth and smooth celadon glaze. Is it a strange phenomenon? How did these phenomena appear? Is it the reason for the recipe? The reason for the craft? Still the reason of the years? Are these different microscopic forms helpful in identifying the authenticity of porcelain? How much help?

Second, different microscopic horizons similar to glaze

In today's antique world, many experts in the industry dismissed and despised the so-called microscopic identification method and bubble identification method. They even regarded people who were keen to study such new identification methods as not taking the right path. Or the generation of misunderstanding. Because in their view, the difference between different glazes is visible at a glance, but also need to see its bubbles? As everyone knows, with the development of modern technology and the advancement of counterfeiting technology, some high imitation porcelains have become closer and closer to the limits that people can distinguish. Whether it is a master or an expert, in the face of many high imitation antiques, the phenomenon of eye-catching and eye-catching has occurred, which fully illustrates the limitations of traditional eyesight identification. Besides, the approximate glaze, the master may indeed be able to see their difference at a glance, but what is the difference? They are not convinced that it is not clear, which makes it difficult to effectively guide later learners. However, if we use modern microscopy technology, even a novice can easily distinguish the difference between the glazed surface. Not only that, but it can also be expressed in graphic terms, which is very popular and popular. Below we use some examples to illustrate.

Four pieces of the same kiln celadon fragments

Let's take a look. This is four pieces of kiln celadon fragments that look very similar. If you don't compare them together, many people will not think that they will make any difference. Even the master can clearly distinguish them, but can't tell where their differences are there? So let's see if their glazed micrographs don't see the difference?

Yue0001

Micrograph. There are countless rock patterns on the glaze, the bubbles are not large, and most of them are oxidized.

Yue0002

Micrograph. The bubbles are dense and rich in layers, most of which are not oxidized, and some are obviously oxidized.

More, but still more than

There are few, there are also oxidized bubbles, but the form of oxidation is different from the former two.

Yue0004

Micrograph. Glazed surface also has texture, but with

001

The lines are completely different, and the other aspects are different from the first three.

Such four pieces of celadon pieces, which look almost indistinguishable from the naked eye, have such a clear and distinct difference under microscopic technology. Moreover, these fragments are all of the same kiln celadon, from the same area, using the same magnification. What can this explain?

First, it shows the phenomena that we can observe with the naked eye, and the phenomena observed by microscopic techniques are two completely different levels. What we can't distinguish with the naked eye can be easily distinguished under microscopic techniques.

Second, the seemingly similar glazes under the naked eye may have various differences in formulation, process, environment and time, so that various differences will occur under microscopy.

Third, if we can hang the various features of the glazed surface of the micro-technique, and glaze formula, firing process, regional environment and weathering, then there is no doubt that the authenticity of the collection can be identified. Play an important supplement and auxiliary role.

Can it really do this? Let's talk with the facts.

Two seemingly similar Tang Qing glaze water jets

These two Tang green glazes are covered with water column, and the shape is almost the same. Look at the glaze, which is a yellowish one. If you look at it alone, in the eyes of experts, the difference is obvious, but in the eyes of novices, you may not see any essential difference. One of these two is the real thing, and the other is the imitation. When you compare it together, it seems that everyone can see the true and the false, but if you look at one of them separately, the situation is different. Do not believe, you can go online to see, inside this real thing so open, after the release of my door series, there are still many people watching it is fake! This shows that with the naked eye, people's distinction between authentic and imitation is not so clear!

Then let's take a look at it. With microscopic identification, can we find some clearer differences between them.

These two are glazed micrographs of the right-hand color yellowish water

These two are glazed micrographs of the left-hand color

In fact, I don't need to explain what I am doing. Just compare the two sets of photos with your heart, and be true and false. In order not to let everyone see too tired, I will briefly explain. The bubble soils in the previous set of images are uniform and all are yellow earth, and almost no live bubbles are visible. The oxidation state on both sides of the open film is also very uniform and neat. The opposite is true in the latter set of pictures. The bandits of the bubbles are yellow, white and black, and there are also shallow and deep changes, and there are many live bubbles. The oxidation state on both sides of the open film is wide and narrow, deep and shallow, and very natural. There are still many differences that can be seen here. I will not explain them here. You can compare them yourself.

These differences, I think anyone can clearly distinguish. The reason for this difference is also very simple. The former group is a replica. It is a bandit and an open enamel caused by acid clay to corrode the glaze. Therefore, the color is almost the same, all the bubbles are almost killed; the latter group is The authenticity, it is the bandit and opening of the natural oxidation caused by the years, the color is of course ever-changing, the depth is different, the bubbles are also oxidized and not oxidized.

What needs to be specially stated is that microscopic identification is also a systematic project. It is not simple to break the truth by some phenomena. The above analysis is only for these two specific devices, so don't simply push them to avoid mistakes.

Third, how to learn and study glazed microscopic identification

1.

How should the concept of microscopic identification be understood?

Many people now have a big misunderstanding of the microscopic identification method. They think that just looking at the shape of the bubble and observing the oxidation of the bubble is microscopic identification. Some people have seen that there are several oxidized bubbles on the glaze, which is asserted to be authentic. Or, different kiln mouths, different positions in the kiln, normal burning, over-burning, and raw burning will produce bubbles of different shapes to confirm that microscopic identification is not feasible. These are caused by the lack of understanding of microscopic identification. The core of the microscopic identification method is to discover and study the glazed features that are available in the microscopic state and that are not available in the imitation. This is a project, a vast project that requires everyone to complete it together. Before this project is completed, we can only find some

It is possible that it will only appear on the real thing, and the glazed microscopic features that are unlikely to appear on the imitation. In other words, microscopic identification does not identify replicas, but it can help people choose the authenticity more confidently.

This glazed microscopic morphology is

Spider Mesh: The glazed surface has a strip-like mesh pattern like a spider web. This mesh pattern is very clear and is distributed on a normal glaze, rather than a corroded glaze. This condition will appear on a large area of ​​the glaze.

This type of glazed microscopic morphology is called

Highway: One or both sides of the glazed surface, with a fine line or atomized surface parallel to it, combined with the opening pattern, looks like a highway. This state will appear in many places in the glaze.

Because this bubble is the result of oxidation and erosion of bubbles by various factors during the long history. At present, no matter how the imitation goods erode the glazed surface, the eroded air bubbles can only present a single color, but cannot present such a complicated color. This point is also reflected in the microscopic glazed state of the original authentic Tang Shui note. The authenticity is rich in color and the color of the imitation is single. Of course, replicas may also be able to enrich the color of the eroded bubbles through a variety of corrosion methods. If so, it will be large-area, and it is not possible to have one or several such ones in a normal bubble community. bubble. Of course, this argument has yet to be tested.

. This parallel atomization state appearing on both sides of the open pattern is most likely formed in a special environment. It appears in the micrograph of Tang Qing glaze, and the oxidation state on both sides of the open film is completely different. Such phenomena have not yet been found in replicas. Its cause is still unknown, and it can't even be speculated. Therefore, if the future replicas want to imitate such features, the difficulty may exceed their imagination.

The characteristics of this porcelain, if found, can be genuine. But this is only a possibility, and the size of the possibility should be further analyzed and judged in combination with other factors.

The times are advancing, science and technology are developing, and the identification of cultural relics cannot be changed. The superstition ophthalmology experience identification, resisting scientific instrument identification is not advisable, self-deception. The identification of cultural relics such as porcelain should go from the surface to the inside, from the surface phenomenon to the inner, so that it is not wrong. In fact, the identification of the ophthalmology of porcelain and the identification of porcelain scientific instruments are not mutually contradictory, and they have always complemented each other and promoted each other. The combination of the two is the new way to identify porcelain!
