Chapter 707: Yellow on red

Xu Desheng held up the jar lightly and looked at it seriously, which lasted more than an hour.
"This is indeed a piece of yellow on red, and it is the best product among yellow on red. What is rare is that the preserved condition is very intact, with almost no flaws visible."
"I have never seen such a good piece of yellow and red, Song Yun, you guys are so lucky."
Xu Desheng shook his head and sighed.
"Old Zhu, Old Xu, to be honest, I don't know much about Huang Shanghong, I wanted to find some information, but since your second elder is here, can you tell me?"
Song Yun picked up the teapot while talking and poured tea for Zhu Deyuan and Xu Desheng. This was definitely not flattering. He knew that it was definitely a good thing, but it was so good about it or where this porcelain was precious. , I don’t want to find some information, but since Zhu Deyuan and Xu Desheng are two experts in front of them, they are not ashamed to ask, they can solve the problem completely, and there is no need to work hard.
Xu Desheng looked at Tang Miaomiao who was sitting next to him.
"Do you know anything about yellow and red?!"
Xu Desheng knew that Song Yun entered the industry relatively late and that porcelains like yellow and red were not common. I didn't know, but it was normal.
"Old Xu!"
"I don't know much about this kind of porcelain!"
"In fact, it is not much different from Song Yun!"
Tang Miaomiao shook her head. She really didn't know much about this kind of porcelain.
"In fact, this is really not to blame you at all. Huang Shanghong is different from the Yuan blue and white porcelain we usually know, and it can be regarded as a kind of rare porcelain."
"Porcelain is divided into white porcelain and colored porcelain. Simply put, the former is white and the latter is colored."
"Yellow on Red" is a very precious variety of colored porcelain in the development history of imperial porcelain.
"Nowadays, it is very rare, one is because the production process is very complicated, and the other is because this kind of porcelain is only used by the court."
"This directly leads to a result that we can see that there are not many yellows and reds, because there are not many that are produced originally. To put it bluntly, it is only used by the emperor, and those concubines. Yes, there must be damage during the use process, plus the hundreds of years passed down to the present, there are really few remaining."
Xu Desheng said while looking at the yellow and red on the table, paused for a while and then continued.
"This thing is a jar. It's huge and even more rare."
Zhu Deyuan nodded, the fact is that the number of Huang Shanghong is very small.
"Old man Xu is right. Because yellow and red are only used by the emperor, the total number is much smaller than other diameters, and even fewer are passed down."
"Besides, the process of adding yellow to red is very complicated."
"In terms of craftsmanship, first the yellow glaze is used as the background color, and after the decorations are outlined, the alum is red. This forms the yellow glaze and the alum red on the surface. From the surface it is the red ground and yellow color decoration. This is the yellow on the red. There is another name called "Red Ground Yellow Color", because there is a large area of ​​alum red. In strong contrast, the yellow color pattern is very noble. This is the color of the emperor, and it was fired by the Ming Dynasty palace office for the emperor. Imperial porcelain. On the other hand, the yellow and red of the Jiajing dynasty had to be fired three times in the kiln."

First, write the name of the drawn embryo in blue and white material, cover it with transparent glaze, and enter it into the kiln for the first firing. At this time, the temperature is as high as 1,300 degrees. After the bisque is fired, the yellow glaze is poured. The second firing will be carried out. At this time, the temperature is controlled at 800 degrees to 900 degrees. The finished product is a whole yellow glaze porcelain, which is selected after leaving the kiln. The third step is to use a black or red pen to outline the dragon and phoenix on the enamel surface. Flowers and other patterns, the yellow glaze after the pattern is covered and filled with alum red on a large area, highlighting the yellow theme pattern, which forms the red ground yellow color. After completing this work, it will be fired for the third time, and the final product It will be a yellow-on-red colored porcelain with red and yellow superimposed."
Song Yun was very surprised. He did not expect that the yellow and red porcelain would go into the kiln three times during the firing process. Perhaps some people think this is nothing remarkable. In fact, it is very scary. You must know that during each firing process, During this period, accidents may happen, let alone three times, the possibility of failure is infinitely magnified.
"It is very difficult to get a yellow and red in good condition. The one you missed is exquisite and beautiful, with a magnificent glaze. It is definitely the best quality yellow and red."
"It really makes people have to admire your good luck!"
Xu Desheng shook his head as he talked. Needless to say, Song Yun's eyesight is invincible. You must know that no matter how good eyesight is, it can only be effective when it comes to encounters.
"Hahaha!"
"Hahaha!"
"My luck is indeed good!"
Song Yun has absolutely no way to deny this incident. In fact, I think carefully about the process of getting this yellow and red. It doesn’t work if I don’t want to admit it is luck.
