Su Chen entered the interior of the kiln and saw the firing process of the craftsmen on site, the steps in the firing process of the kilns, kiln tools, and the control of fire temperature, and carefully observed it.

The kiln has cylinder and leak-shaped caskets, cushions, pillars, fire illumination, etc.; porcelain making tools include shaft caps, etc. This is the first time Su Chen has seen these tools on site.

Su Chen found that there was no coal near the kiln in the kiln. He said curiously: "What do you use to burn fire to increase the temperature?"

A rough craftsman turned his head and replied, "Of course it's firewood, otherwise what else can I use?"

Su Chen pondered for a while, then he realized that before the Northern Song Dynasty, ancient people used firewood to make ceramics. In the middle of the Song Dynasty, some official kilns in the north changed to coal as fuel.

Although the firewood burns quickly, the ashes fall into the ash pit after burning out, leaving no thick burning layer behind. Therefore, the frequent, fast and less firewood burning method also provides favorable conditions for the steady rise in the furnace temperature.

When the firewood is burning, the flame is long and the flame is soft. The carbon monoxide atmosphere generated is suitable for the thickness and light, creating a good environment for the reduction of the copper elements in the porcelain glaze. Therefore, the glaze colors of the wood kiln products penetrate each other naturally, presenting a clear and elegant beauty, handsome and elegant beauty.

However, it is necessary to control the flames and heat. Often, waste furnace defective products often appear because of insufficient fire temperature, which is very high in waste products and is time-consuming and material-consuming.

Su Chen observed for a long time, then found a problem and said, "Your kiln is a bit unreasonable and the fire net area is small. You can improve it."

An old craftsman said, "We have always burned porcelain like this. For decades, there is no problem with the kiln. If there is not enough fire, just add firewood and burn it hard!"

Su Chen's lips shook, and he did not continue to explain, but recorded this point. He thought that when he was firing ceramics in the Song Dynasty, it seemed that he used a two-peak kiln, with double fire burning increasing the area of ​​the fire net and double fire outlets taking turns to add firewood, which was conducive to the steady increase of the furnace temperature during the firing process. However, this was just a small change, which could be realized, but could not change the overall situation.

If the Bai family wants to win with the Ding family, in addition to celadon and white porcelain, new porcelain also needs to appear, such as blue and white porcelain, or more beautiful blue and white porcelain. However, the latter blue and white porcelain is difficult to deal with, so I should study the reality of blue and white porcelain first.

According to historical records, Qingbai porcelain appeared at the end of the Five Dynasties and the beginning of the Northern Song Dynasty. Su Chen calculated the time and it was almost the same.

Blue-white porcelain is also called "shadow green", which refers to a kind of porcelain whose glaze color is between the two colors of blue and white, with white and blue in the blue. Blue-white porcelain is a new variety with unique styles and distinctive characteristics of the times during the Song and Yuan dynasties. It has been burned into a new variety with unique styles and distinctive characteristics. From the Song to the Yuan dynasties, blue-white porcelain has been burned forever.

"The Bai family is best at white porcelain, and has mastered the method of refining in small mature celadons. As long as they are mixed and tested, they may be able to fire blue and white porcelain. Then its ornamentality and value may soon surpass white porcelain and celadon." Su Chen thought in his mind, but there was no specific operation method yet, so he decided to observe it again and go back to consider it.

Next, Su Chen, regardless of his identity as a scholar, participated in it himself, and followed the craftsmen to learn the process and specific operation methods of porcelain firing, such as the important steps of mud, molding, glaze, and firing. He planned to practice firing by himself through observation and learning.

Bai Susu saw Su Chen as obsessed with research, and her eyes showed a hint of confusion and a little appreciation. Su Chen... was serious in his work, which was quite attractive!

………

Runzhou, in Hongxiufang.

In the attic of the third courtyard, the flower actress Fu Chan'er, Qiu Zhilan, the flower actress of Cuiwei Pavilion, and Su Xiaowan, the flower actress of Tongque Tower, sat around the table, discussing how to deal with the pressure of Liu Monan in Xiangyun Pavilion.

The three beauties are all flower actresses and are strong competitors to win the courtesan. Last year, Fu Chan'er won the championship and was the most popular because the financial owners behind the scenes spent enough money, but compared to their appearance, the three girls can be said to be spring orchids and autumn chrysanthemums, each with their own strengths, and they are not inferior to each other at all.

In the past, the three girls rarely interacted and were all in secret, but now that Liu Moonang became very popular, they got together privately and were forced to form a temporary alliance.

Qiu Zhilan was wearing a plain white long dress, white and elegant, and had a beautiful appearance. She said to Fu Chan'er: "Sister Fu, your Hongxiufang has not been easy these days, right?"

Fu Chan'er nodded generously and said, "I underestimated Liu Mo Nong's methods at the beginning. I didn't expect that she could create a new form of stage drama. Since she performed three West Chambers, I heard that every event was full, and the admission tickets had already been charged ten cents. This is not the double increase in the front seats. The powerful and gentry families in Runzhou City are mostly scrambling to watch them, which has a great impact. In addition to the entry tickets, it also has a West Chamber effect. The guests who go to Xiangyun Pavilion to have a drink and have fun every day have also doubled."

Su Xiaowan had a delicate face and a delicate body, but a huge childish face. She was particularly charming. She straightened her chest and said, "Yes, there are only so many powerful people and gentry in Runzhou City. If they all flock to Xiangyun Pavilion, our flower buildings will be greatly impacted."

Qiu Zhilan sighed, "Which talent came from Su Yixuan was so powerful? It is said that at the Xu Mansion Poetry Conference, he wrote poems and lyrics, and he was amazing in every couplet with Ye Tanhua. His fame was suddenly sought after by scholars in Runzhou. Now he is called the number one talented man in Jiangzuo."

Su Xiaowan asked tentatively: "Sister Fu, Sister Qiu, do you know how Liu Mo Nong got along with Mr. Su Yixuan?"

Fu Chan'er said: "I heard that Liu Mo Nong went to Bai Mansion and found Bai Susu, the eldest daughter of the Bai family, and then hired Su Yixuan to write the script of the West Chamber for a lot of money."

Qiu Zhilan had a sudden inspiration and suggested: "It would be better for us to go to Bai Susu and beg Bai Susu that it would be best to meet Su Yixuan! Even if we can't see him, we will pay a lot of money to write a play for each of us. In this way, we will have the reputation of drama and be equal to each other, and Liu Mo Nong's advantage will be gone."

Su Xiaowan snorted softly, "I don't know if Mr. Su will help! If Liu Mo Nong is ashamed of using fox tricks to Mr. Su Yixuan behind his back and recommends himself to the pillow mat, Mr. Su will not help us!"

Fu Chan'er frowned, and then thought of a plan: "Why, let's continue to spread rumors. Liu Mo Nong has a close relationship with a doctor named Su Chen. He said that after she fell into the water, Su Chen had a flirtatious relationship with Meng Lang and kissed her mouth. Afterwards, Liu Mo Nong fell ill. He stayed in Liu Liu Mo Nong's room for a night but did not return. According to Cui Qiaoer and the others in Xiangyun Pavilion, Su Chen and Liu Mo Nong are suspected of having an affair. We can wear this matter very much, and everyone in the city knows. At that time, Liu Mo Nong's reputation is not good, and Mr. Su Yixuan will also dislike her, and Bai Susu will not stand by and let the man who pursues her, and is so entangled with the brothel girl. By then, Liu Mo Nong's chance to obtain a dramatic script will be cut off."
