Su Chen entered the interior of the kiln and saw the firing process of the craftsmen on the site inside, as well as the steps in the kiln, kiln furniture, and firing process, as well as the control of the fire temperature, and carefully observed.

The kiln has cylindrical and leak-shaped sagger, cushion cake, pillar, firelight, etc.; Porcelain-making tools include shaft caps, etc. This is the first time Su Chen has seen these tools on the spot.

Su Chen was in the mouth of the kiln, and found that there was no coal near the kiln, and said with some curiosity: "What do you use to burn the fire to increase the temperature?" ”

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

Su Chen pondered for a while, and then suddenly realized that before the Northern Song Dynasty, ancient people used firewood to burn ceramics, and in the middle of the Song Dynasty, some official kilns in the north switched to using coal as fuel.

Although the firewood burns quickly, the ashes fall into the ash pit as soon as it is burned out, leaving no thick layer of combustion. Therefore, the diligent, fast and less firewood firing method also provides favorable conditions for the steady rise of furnace temperature.

When the firewood is burned, the flame is long, the flame is soft, and the carbon monoxide atmosphere produced is appropriate, which creates a good environment for the reduction of the copper element in the porcelain glaze.

However, the control of fire and heat needs to be moderate, often because the fire temperature is not enough, there are often defective products in the waste furnace, and the waste rate is very high, which is time-consuming and material-consuming.

Su Chen observed for a long time, and then found a little problem, and said: "Your kiln is a little unreasonable, and the fire net area is also small, so you can improve it." ”

An old craftsman said: "We have always burned porcelain like this, for decades, there is no problem with the kiln, the fire is not enough, so add firewood and burn it!" ”

The corners of Su Chen's mouth twitched, and he didn't continue to explain, but recorded this. He thought of the Song Dynasty firing ceramics, it seems that the use of two-peak kilns, double fire to increase the area of the fire net, double fire port to take turns to add firewood, is conducive to the steady rise of the furnace temperature in the firing process, but this is only a small change, can be realized, but can not change the overall situation.

If the Bai family wants to win in a hard fight with the Ding family, in addition to celadon and white porcelain, new porcelain is also needed, such as blue and white porcelain, or more beautiful blue and white porcelain, but the latter blue and white porcelain is difficult to do, so it is better to study the reality of green 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.

Qingbai porcelain is also called "shadow blue", which refers to a kind of porcelain with a glaze between blue and white, white in blue, and blue in white. Qingbai porcelain is the Song and Yuan Dynasty Jingdezhen and the kiln affected by it, fired into a new variety with the unique style and distinctive characteristics of the times, from the Song Dynasty to the Yuan Dynasty, Qingbai porcelain is flourishing.

"The Bai family is best at white porcelain, and has also mastered the refining method of immature celadon, as long as they are mixed with each other and tested, they may be able to fire blue and white porcelain, then its ornamentality and value may soon surpass that of white porcelain and celadon." Su Chen thought so in his heart, but he didn't have a specific operation method, so he decided to observe it again and go back to think about it.

Next, Su Chen disregarded his identity as a scholar, personally participated in it, and followed the craftsmen to learn the process and specific operation methods of porcelain burning, such as several important steps of mud matching, molding, glaze matching, and firing and forging.

Bai Susu saw Su Chen so fascinated and engaged in research, his eyes showed a trace of doubt, and he also had a little appreciation, this Su Chen ...... The serious demeanor of doing things is very attractive!

………

Runzhou, inside the Red Sleeve Fang.

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

The three beauties are all Hua Dan, strong contenders for the Oiran, last year Fu Chan'er won the championship, the most popular, that is because the behind-the-scenes financiers spend enough money, but compared to their appearance, the three daughters can be described as Chunlan Qiuju, each with its own merits, and they are not inferior to each other.

In the past, the three women rarely interacted with each other, and they all competed in secret, but now that Liu Monong has become popular, they have come together privately and are forced to form a temporary alliance.

Qiu Zhilan was dressed in a plain white dress, white and elegant, with a beautiful appearance, and said to Fu Chan'er: "Sister Fu, your life in the Red Sleeve Workshop is not easy these days, right?" ”

Fu Chan'er nodded generously and said: "At the beginning, I still underestimated Liu Monong's means, I didn't expect her to come up with a new form of stage drama, since I performed three performances of the West Chamber, I heard that the venue was full, and the admission ticket had been charged to ten yuan, not counting the doubling of the seats in the front row." Most of the powerful people in Runzhou City and the female relatives of the squire's families are vying to be the first to see, and the influence is too great. In addition to the admission ticket, it also produced the West Chamber, and the number of guests who went to Xiangyun Hall to eat and drink every day also doubled. ”

Su Xiaowan has a delicate complexion and a delicate body, but she is very charming, and at this time she straightened her chest and said: "Yes, in Runzhou City, there are so many powerful people and squires, if they all flock to Xiangyun Pavilion, several of our flower buildings will be greatly impacted." ”

Qiu Zhilan sighed: "This Su Yixuan, where did he come out of talent, how could he be so powerful?" It is said that at the Xufu Poetry Conference, he wrote poems and lyrics, the first one was amazing, and Ye Tanhua also won the couplet, and his fame was suddenly sought after by the scholars in Runzhou, and now he is known as the first genius in Jiangzuo. ”

Su Xiaowan asked tentatively: "Sister Fu, Sister Qiu, do you know how Liu Monong caught up with Su Yixuan's son?" ”

Fu Chan'er said: "I heard that Liu Monong went to Baifu and found Bai Susu, the eldest lady of the Bai family, and then hired Su Yixuan to write this script of the West Chamber. ”

Qiu Zhilan had an idea and proposed: "Why don't we go to Baifu and plead with Bai Susu, it would be best to see Su Yixuan!" Even if we can't see each of us, we will pay a lot of money to ask him to write a play for each of us, so that we all have the fame of drama blessings, and we will be equal to each other, and Liu Monong's advantage will be gone. ”

Su Xiaowan snorted lightly: "I don't know if Su Gongzi will help!" In case Liu Monong is not ashamed, and he uses fox tricks against Su Yixuan Gongzi behind his back and recommends himself to the pillow seat, then Su Gongzi will not help us! ”

Fu Chan'er frowned, and then thought of a plan and said: "It's better for us to continue to spread rumors, Liu Monong has a lot to do with a Lang Zhong named Su Chen, let's just say that Su Chen once fell into the water after she fell into the water, so he got on the boat and lightly Meng Lang and kissed her on the mouth, and afterwards Liu Monong fell ill, and he stayed in Liu Liumonong's room at night and did not return." According to Cui Qiaoer of Xiangyun Pavilion, this Su Chen is suspected of having an affair with Liu Monong, and we can dress this matter up and know it all over the city. At that time, Liu Monong's reputation is not good, Su Yixuan's son will also be disgusted with her, and Bai Susu will not stand idly by, allowing the man she likes to pursue her to be entangled with the Qinglou woman like this, and at that time, Liu Monong's opportunity to get the script of the drama will be cut off. ”

Su Xiaowan chuckled and said: "This plan is very good, the more realistic it is, the better, see how Liu Monong can save her reputation!" ”
