If you want to imitate Yuan blue and white, especially when making human figures and bird and animal patterns, you need to avoid blurring when depicting eyes.
However, if you don’t understand Yuan Qinghua, or the characteristics of Suma Liqing, it is difficult to avoid this.
Again, Chen Wenzhe is now standing on the shoulders of countless masters, or standing directly on their heads, so it is naturally easy to solve these problems.
Therefore, when he bakes Yuan blue and white, his success rate should be very high.
After all, even in the Yuan Dynasty, if the figures' eyes were blurred in the Yuan blue and white figure jars, it would be a failure.
For example, the Yuan blue and white vase with the picture of Guiguzi descending the mountain, and the vase with the picture of Chasing Han Xin under the Moon. There are characters in these, and the characters' eyes are not blurry.
This is also one of the main reasons why this kind of picture jar is very expensive.
Because of the problem of halo, it was difficult to successfully fire this kind of pot in the Yuan Dynasty.
Rare things are more valuable. This is true in any period.
At this time, it is not difficult for Chen Wenzhe to solve this problem.
If you want to solve the problem of halo, you must first know the cause, that is, understand the characteristics of Suma Liqing, and understand the level of craftsmanship at that time.
As long as you understand some of the situation back then, it is not difficult to analyze the reasons.
First of all, cobalt material such as Su material has coarse particles and complex composition.
Secondly, the green-white glaze is viscous in fluidity and thick.
Finally, there is the unique kiln reduction flame process temperature atmosphere.
Among these three main causes, the first is the most important.
Because other materials, such as domestic materials, will not appear haloed even if the particles become coarser.
As for modern pigments, no matter how fine or thick they are, they cannot be properly dispersed. This is because the complexity of the ingredients of Su paint cannot be imitated.
Of course, anything can be imitated, it just depends on whether the price paid is worth it.
In the 1980s, when the country wanted to imitate Yuan blue and white, it was not imitated?
However, it is the power of the country, so if Chen Wenzhe wants to imitate it, he must take shortcuts.
It was because he had learned the craftsmanship of those masters who imitated Yuan blue and white in China, and had seen the entire production process of Yuan blue and white, that he was so confident and finally succeeded in firing.
If there were no multiple cheating methods, the only way to re-burn Yuan Qinghua would be to rely on time and funds.
Especially the Su material, with its dual nature of both condensation and dispersion, is almost unique.
It is difficult to imitate this characteristic, at least for individuals, it is very difficult.
Of course, as long as you understand the characteristics of su material, it is not difficult to solve the problem.
For example, because the blue-white glaze is quite thick and has a viscous fluidity, it can allow the pigment to fully react and control the halo, or allow the larger impurities in it to agglomerate and float, causing halo.
Most Yuan blue and white utensils are more or less mixed with domestic materials or returned green materials, so the condensed matter halo effect will be greatly reduced.
The so-called halo-dispersion effect of condensed matter means that one must be condensed and the other must be halo-dispersed, one of which is indispensable.
This is also regular. For example, the performance after mixing domestic gravel green material is very obvious.
For example, the point-like condensed state phenomenon of bead-like black spots has weakened, that is, the black spots have become fewer and more concentrated together.
The result is that the black spots can change into various connected states, or become larger irregular spots such as lumps and strips, and the edges of the spots become less or less blurred.
Then there is the background color of the pigment, that is, the "color halo" state weakens, that is, it transforms into a non-halo state.
This is caused by the convergence properties of the domestic stone green material itself.
If Chen Wenzhe imitates only one or two pieces of Yuanqinghua, it doesn't matter. It's okay for him to use Suma Liqing for all.
However, there are many Yuan blue and white flowers that he wants to imitate. As long as they are handed down from ancient times and have some reputation, he will imitate them.
During this process, the performance of many Yuan blue and white flowers is more than what Sumali Qing material can achieve.
At that time, when making Yuan blue and white flowers, except for some high-quality products, which all used Sumali green material, many other green materials were also used.
In addition to the stone green material that is popular in China, there are also some green materials that have been mixed into western my country.
You must also know how these green materials will behave after being mixed in. Otherwise, others may notice that the color of the imitation is wrong at a glance.
Just like green material, if this green material is mixed, the dot-like condensed matter phenomenon of bead-like black spots on the glaze surface will eventually weaken and diverge.
That is, small black dots or spots, etc., become slightly blurred or blurred, that is, the condensed matter is insufficient and over-divergent.
Then there is the base color of the pigment, which is the "color halo" state, which will be retained until it is enhanced.
This is caused by the divergence of the greening material itself, which can be seen as long as it is used.
With such obvious features, as long as you have a little knowledge, you can tell something when appraising Yuan blue and white, so Chen Wenzhe had to pay attention.
The halo and dispersion characteristics of Yuan blue and white cobalt materials are quite obvious, so it is regarded as one of the main characteristics of Yuan blue and white.
This characteristic is already formed when it is fired and comes out of the kiln, and it further deepens as time goes by.
The dispersion forms of Yuan blue and white cobalt materials are also different and can be roughly divided into three categories.
The most obvious one is the dotted type mentioned earlier. The characteristic of the dotted type is that there are many dotted blue and white spots scattered over a large area on the glaze.
This phenomenon only occurs when imported Suma Liqing is used, and it feels like a handful of pepper is sprinkled on the surface.
Some people believe that the cause of this phenomenon is that the cobalt material is not ground finely and the remaining particles are caused;
Although there is some truth, it is not enough to explain everything.
Because this kind of particles are not only found in areas painted with blue and white, they also exist in blank areas that are not painted with blue and white, and are even distributed over a large area.
What exactly causes it and the formation mechanism need to be further explored.
In the crystalline form, this halo is actually caused by crystal spots.
The combination of dotted and linear rust spots creates a special halo effect.
It is characterized by irregular tooth-shaped burrs on the edges, some of which are plush-like.
This type of halo is mainly caused by imported cobalt materials with high iron content and prone to rust crystal spots.
Finally, there is the flowing type. The flowing type of halo is formed by the cobalt material flowing in the glaze. It is also the most common form of blue and white halo and has various expressions.
Of course, scattered halo is not a unique phenomenon in the Yuan Dynasty and the early to mid-Ming Dynasty. It existed even in the Qing Dynasty.
It can be said that the blue and white halo phenomena in the Yuan, Ming and Qing dynasties all have their own characteristics and are also different.
For porcelain collections, blue and white porcelain is one of the most familiar varieties.
Among blue and white porcelain collections, blue and white from the Yuan, Ming and Qing dynasties dominate.
However, during the Yuan, Ming, and Qing dynasties, the blue and white porcelain had different dispersions due to the different production techniques and materials used in each period.
Thus, the difference between the blue and white flowers in the Yuan Dynasty, the early Ming Dynasty and the Qing Dynasty was formed.
