The difference between blue and white scattered halos is easy to distinguish as long as you know it.

In the Yuan Dynasty and early Ming Dynasty, blue and white colored materials contained more calcium.

This makes the calcium feldspar crystals on the reaction layer develop particularly well.

This is why the high-temperature viscosity of the glaze near the reaction layer is reduced and the fluidity is improved.

Therefore, it is conducive to coloring materials diffuse from the colored area to the non-colored area, resulting in diffuse.

On the contrary, there were no blue and white flowers in the late Ming Dynasty and the Qing Dynasty.

During the identification process of blue and white, it can not only be seen from the dispersion of blue and white, different blue and white production processes and different blue and white color materials, but also preliminary identification of the approximate age of blue and white.

Chen Wenzhe was so familiar with this thing that he couldn't be more familiar with, so he took a moment to pass by it after careful attention.

He still remembered that what he made at this time was not Yuan blue and white, but yellow-glazed porcelain.

Compared with Doucai, Chenghua's yellow glaze is definitely not as good as Hongzhi.

However, Hongzhi Huang Glaze also inherited its own Chenghua period.

Therefore, as long as the Hongzhi classic yellow glaze porcelain is imitated, then it will be absolutely fine to imitate it into the melted yellow glaze.

Of course, no matter which dynasty it is, as long as it is an official kiln, it is not so easy to imitate.

For example, the Hongzhi Official Kiln is famous for its characteristics.

However, they are also passed down from generation to generation, and naturally they have their own similarities.

For example, in the shape of the Hongzhi Dynasty, the pattern style and style of the porcelain are relatively similar to Chenghua, and there is always the saying that "Chenghong" is indistinguishable.

What changes slightly is that Hongzhi's carving type types are more abundant than Chenghua.

During the Hongzhi period, new instruments such as beast ear bottles and gourd bottles appeared.

These new instruments are honest in shape and are not as exquisite as Chenghua instruments.

Small and thin tires like Chenghua have been greatly reduced, and the process is not as exquisite as Chenghua.

However, the outstanding representatives of Hongzhi official kilns - yellow glaze and yellow glaze blue and white ware, are the most famous color glaze varieties in Ming Dynasty porcelain.

The firing of yellow glaze during the Hongzhi period of the Ming Dynasty reached the highest level in the history of low-temperature yellow glaze.

Moreover, Hongzhi yellow porcelain is a type of utensil specially made for the palace.

No matter how big or small the objects are, they are all exquisite.

Therefore, Hongzhi porcelain became one of the six most precious instruments in the Ming Dynasty.

These six precious types are Hongwu underglaze red, Yongle sweet white, Yongxuan blue and white, Xuande five-color, Chenghua Doucai, and Hongzhi gouhuang.

From the perspective of firing technology, firing type, or firing quantity, they are all role models of yellow glaze ware in the Ming Dynasty.

At this time, the yellow glaze is applied on white glaze porcelain or vegetation. The glaze is poured by the method of pouring the glaze, which is called "pouring yellow".

Because its glaze color is delicate, elegant, and as bright as chicken oil, it is also called "美雪" and "雪美雪米" and "雪米米米米米米米米米米米米米米米米米米米米米米米米米�

The firing temperature of the yellow glaze is between 850-900℃, and the stability is higher than that of other low-temperature glazes.

The transparency is high, so that the patterns engraved on the body can be revealed through the glaze layer.

In recent years, the prices of yellow-glazed porcelain have risen and are highly respected.

Especially the Hongzhijiao yellow glaze, which represents the highest level of yellow glaze porcelain, is more precious.

First, Hongyejiao yellow glaze porcelain has regular shapes, fine and clean finishes, and white glaze on the bottom.

In the early stage, it is the same as Chenghua white glaze, it turns gray in the middle stage and cyan in the late stage, which is consistent with Zhengde's bright cyan.

Second, there is a collapse at the bottom of the Hongzhi blue and white porcelain plate, and the latter imitations are mostly flat bottoms.

The bottom foot of the Hongzhi utensil is low, the ring foot is smooth, and the bottom foot of the imitation is slightly higher.

The third is that the three dots of water in the character "正" in the text are generally lower than the character "天", and the three dots of water in the latter form are equal to the character "天".

Fourth, the chicken oil of Hongzhi yellow glaze is yellow, which is extremely difficult to imitate.

Hongye yellow glaze was glazed twice, both of which were very fine, and the edges were neat and natural in the contact between the white glaze or white body. Those who imitate later were more restrained.

It is yellowish and white during Chenghua, and those who imitate it later often have dark yellow colors.

After Hongzhi, yellow glaze was produced throughout the ages. The Zhengde Dynasty inherited the Hongzhi tradition, but the yellow color was heavy, giving people a sense of meticulousness and perseverance.

The yellow glaze clusters in the Jiajing Dynasty were light to dark yellow, and the glaze surface seemed to feel uneven.

It may be glaze on the brush stroke method, and there are also glazes with uniform glaze surfaces. It is estimated that glaze on the blowing glaze method is used.

During Jiajing, I was accustomed to painting red color on yellow glaze and on low-temperature red glaze.

Some yellow glaze ware have sufficient bases to apply yellow glaze, and are engraved with official styles.

There are few yellow glaze ware in Wanli, mostly bowls, with dark yellow and no longer delicate yellow.

During the Hongzhi period of the Ming Dynasty, the glaze of delicate yellow glaze was bright and elegant and pleasing to the eye. It is recognized as the highest level in history. Compared with the glaze of delicate yellow glaze of the Xuande period, it is more refined and oily.

Moreover, the firing process requirements were extremely high, and later imitations could not reach the level of the Hongzhi dynasty.

It can be said that it is unprecedented and has never been around, so Hongzhijiao yellow glaze deserves to represent the highest level of yellow glaze porcelain!

The best yellow-glazed porcelains in various dynasties in the Ming Dynasty were recommended during the Hongzhi period.

Therefore, in the history of ceramics, it is often regarded as a typical example of yellow glaze in the Ming Dynasty, and is called "Hongzhi Jiaohuang".

Its artistic achievement was the crystallization of the peak period of the process technology based on the continuous exploration of the firing process.

Since yellow glaze is the most strictly controlled glaze color in the royal family, it was mostly supplied by the imperial kilns during the Ming and Qing dynasties.

Therefore, his status is noble and is an important product of imperial kiln porcelain.

Hongzhi yellow glaze is mostly applied to plates and bowls.

The circumference is higher than Xuande and Chenghua is shorter.

And when it is closed to the bottom, there is often a lighter flint red at the intersection of the body and glaze.

In addition, the bottom of the plate and bowl are mostly irregularly sunken.

According to Mr. Feng Xianming's research, there is another obvious difference between Hongzhi yellow glaze and later imitations.

That is, the three dots of the character "zhi" in the six-character version of Hongzhi yellow glaze are obviously lower than the character "tai".

In fact, these are not the most important things in imitation.

The most important thing is that there are some unique ingredients in the Hongzhi yellow glaze ware.

Often, whether you imitate or not, you will know the unique ingredients from this point of view!

Just talk about Hongzhi Pohuang. The glaze color of this kind of porcelain can be seen under a magnifying glass, and the oblique patterns of the Ru ware can be seen.

Why is this happening? This is why the unique glaze recipe is.

It can also be seen from this that a certain proportion of agate powder must be incorporated into the glaze.

Since glazing is casting, glaze accumulation must exist.

Due to the superposition effect of colored glaze, the glaze accumulation appears red and yellow.

Although Hongzhi's style is blue and white, it may be due to chemical reactions. The color of the yellow pourer is the same as that of the peacock green blue and white, and it presents a dark blue black color.

Because Hongzhi's body glaze is extremely fine, its style not only does not sink, but will instead bulge.

Hongzhi Jiuhuang is a low-temperature device, but Hongzhi’s large instrument also has high-temperature devices.

But the yellow of the high-temperature device is red in its head, and it is extremely expensive.

Hongzhi's yellow-glazed green dragon utensils are also very expensive and have a unique style.

Because Hongzhi's body is fine and incorporates a variety of precious elements such as gems, although it is extremely delicate, it must be the sound of metal when hit.

The Hongzhi yellow-watering vessel was made of yellow color in the previous dynasties and later generations, making Hongzhi delicate and charming.

True or false, this dynasty is still a later imitation tool. As long as it is put together, there is no need to say anything, and there will be a conclusion.
