Two days later, Li Congyan and his entourage came to the east of Dengzhou City.

By this time, the ruined earth temple in the eastern part of the city had been razed to the ground and replaced by a large area of neat buildings surrounded by a high wall. This is the glass workshop that has just been built.

Li Ren and Li Sisheng were already waiting at the gate of the glaze workshop, and after the two met, they hugged Li Congyan and entered the workshop. I saw that the gate had been firmly guarded by a team of soldiers of the new army, and all the soldiers saw Li Congyan standing solemnly and saluting neatly.

"Ling Zun is righteous, and I am very relieved to let Master Li come to help!"

Li Sisheng didn't even dare to say it, and said with his crossed hands: "This matter is also very beneficial to my Li family, and it is also an honor for my Li family to be able to work for Li Tingshi." ”

"Haha!" Li Congyan laughed a few times and rode forward.

Under the leadership of Li Ren and Li Sisheng, Li Congyan successively inspected the raw material room, screening room, cleaning room, blast furnace for firing glaze in the glaze workshop, etc., each process and equipment were built in accordance with Li Congyan's requirements.

At this time, after three hundred years of development and precipitation in the Tang Dynasty, whether it is construction technology or handicraft technology, there has been great development in China, not to mention that the technology of firing glaze has existed as early as the Spring and Autumn Period, and now Li Congyan is just optimizing and improving it on the basis of the original, and naturally there is no technical bottleneck.

In fact, there are three conditions that must be met for firing glaze:

One is that there must be suitable refractory materials, preferably refractory bricks that reach the steelmaking level, and now there are relevant talents in the military station in Dengzhou City, so this condition has been met.

The second condition is to use quartz sand with high purity as the main raw material for firing glaze, which is a bit difficult in Dengzhou at this time, so it can only be selected, powdered and calcined for general quartz sand.

The third condition is to add lead oxide in the calcination process, and the ancient Chinese glaze industry basically only produces glaze, the reason is that the role of lead oxide has not been mastered. Lead oxide is still called lead yellow at this time, which is not a rare thing and can be easily bought.

In addition, in addition to the complete raw materials, the solution must be constantly stirred during production, so the glazed furnace also needs a new design. According to Li Congyan's design, Li Sisheng has organized six new glazed furnaces, which can fully ensure the output and quality of glaze.

After some inspection, Li Congyan was very satisfied with the construction of the glaze workshop, so he asked Li Sisheng: "The workshop has been built, and I have also given you the technology of firing glaze, and now everything is ready, when can the workshop start, but what are the difficulties?" ”

Li Sisheng was very respectful to the young prince in front of him, not only because Li Congyan gave him the opportunity to enter the Liuli Workshop to display his talents, but also because Li Congyan's decisiveness and courage in killing are a rare hero nowadays, so Li Sisheng admires it in his heart.

"Qi Li Thorn History, now more than 300 craftsmen have been recruited in the workshop, according to the requirements of the Thorn History Office, all have been verified and registered, and they live in the workshop together with their families, and everyone is not allowed to go out before the end of the three-year construction period."

"At present, there is no problem with the operation of the workshop, and the glaze seed material is also well stocked, but the craftsmen still have some doubts about the firing details of the glaze......

Speaking of this, Li Sisheng gestured to a craftsman behind him, only to see the craftsman fork his hand and say, "The little one has seen Li Thorn History." The small one is responsible for the supervision of the addition of raw materials in the firing, and the doubts mentioned by Director Li are from the small one. ”

Li Congyan walked into a long corridor, motioned for everyone to sit on the ground, and said to the craftsman with a smile: "Okay, you can talk about it." ”

In fact, the problem mentioned by the craftsman was how to add ingredients when calcining quartz sand.

Li Congyan organized the language and began to explain: "The main raw material of glaze is quartz sand, and you all know that quartz sand is added to soda ash, limestone and feldspar during the calcination process, among which only soda ash is the most difficult. The difficulty for you is also here, the general problem is that the purity of soda ash is not enough, and the quantity is insufficient. ”

"In the vicinity of Dengzhou, the large supply of trona for firing glaze mainly comes from alkali lakes and solid alkali ore. Especially in alkaline lakes, the workshop can arrange for people to boil lake water to obtain soda ash, and the specific method can be done as follows......"

“…… Next up is calcination! Quartz sand, soda ash, limestone, feldspar and other block raw materials are all finely crushed to make the wet raw materials dry. Subsequently, in order to ensure the quality of the glaze, we also need to find a magnet to remove iron from the raw materials......"

“…… In addition, there is a big problem in the firing stage, that is, the temperature of the fire needs to reach the level of refining steel. Therefore, the fuel for calcining the glaze also uses the coke used in steelmaking......"

As early as the Kaiyuan period of the Tang Dynasty, there were records of the use of oil, and at this time the people were no strangers to coke, and there were even workshops selling coke in Dengzhou City, so it was not difficult to obtain coke.

"When the solution flows out, it will be connected to a special iron mold, and after it is cooled and set, it will be colored glass of various shapes!"

After hearing this, Li Sisheng immediately said: "Li Tingshi, don't worry, I will send someone to contact the coke merchants in the city tomorrow, and start arranging for people to burn coke in the workshop for later use." ”

"Good."

After everyone chatted about technology, Li Congyan asked: "There are six blast furnaces of various types in the glaze workshop, have you estimated the monthly output and income?" ”

Li Ren said with a smile: "In this regard, Director Li is an expert, let's talk about it." ”

Li Sisheng did not shirk himself, and said: "Qi Li Thorn History, I plan to spend twenty days to a month to screen the hoarded raw materials, and then start full production. If the six blast furnaces are fully produced, they can produce no less than 3,000 pieces of various glass bottles, glass cups and glass ornaments every month! ”

"As for the earnings......"

Li Sisheng thought for a while and said: "At present, the glass can only be sold to various prefectures and cities, or sold to Luoyang, Chang'an and other places, although some can be sold in other places, but they are scattered and cannot be sold at a high price." During this time, I have contacted 17 caravans and families, and they can distribute them all over the world after the production of the workshop, and it is expected that there will be more than 100,000 yuan per month! Of course, these estimated benefits are net benefits minus costs. ”

"100,000 per month!"

Li Congyan was happy in his heart, if everything went well in the Liuli Workshop and the Haiyan Workshop, the monthly share of the Thorn History Mansion would be more than 100,000 yuan, which could fully support the current expenses of the new army, and also support all the expenses of the steel mill he was going to build next!

"Good!"

Li Congyan finally knows what it feels like to have money and food in his hands, at least in the near future, he doesn't have to worry about money and food anymore, of course, in the absence of major wars and disasters.

Li Congyan encouraged Li Ren and Li Si to be promoted again, and then got up and prepared to return to Dengzhou City.

Before leaving, Li Congyan gave Li Ren a look, and Li Ren's comprehension horse was a few steps behind, and he opened the distance with Li Congyan with a group of casual personnel, leaving only Li Congyan and Li Sisheng riding in front.

Li Congyan first talked with Li Sisheng with a few smiles, and then changed the conversation and asked, "I heard that Ling Zun seems to be a little worried about participating in the Liuli Workshop, I don't know if it's true or not?" ”

Li Sisheng was stunned for a moment, and hurriedly said: "Don't misunderstand Li Tingshi, Grandpa is just a little ...... and a little cautious. ”

"Cautious?"

Li Congyan smiled and said, "It's okay to be cautious." By the way, I also heard that your eldest brother is also in business? ”

"Exactly."

"Then what is his attitude towards the Glass Workshop?"

Li Sisheng didn't know why Li Congyan asked this, hesitated for a moment, and then said, "My brother was against the Li family's involvement in the glaze workshop at first. ”

"And now?"

Li Sisheng wanted to speak again and again, and finally shook his head and sighed.

Li Congyan paused and said: "After these days of contact, I think you and Li Siye are both talents, you are both talents who are in business and martial arts, and they are all talents that I urgently need in the Assassin History Mansion, I love and cherish talents, so I give you a suggestion today: Everything is based on the overall situation!" ”

"What's the big picture? Protect the family internally, and follow me to stabilize the party externally, this is the overall situation! ”

After speaking, Li Congyan waved his hand and returned to Dengzhou City with a large group of people.

Li Ren rode his horse to Li Sisheng's side, looked at the team of people and horses in the distance, and then looked at Li Sisheng, who was a little sluggish, and said: "The master of my family is a state assassin, and he can naturally know a thing or two about the situation of your Li family, so there are some things that Director Li still has to weigh. ”

Li Sisheng suddenly glared at Li Ren and asked, "What does Li Tingshi mean by this?" Could it be that Li Tingshi can't do anything to my Li family! ”

"Haha!"

Li Sisheng frowned slightly, and said, "What does Li Tingshi mean, you might as well say it directly!" ”

After Li Ren laughed, he said: "I heard that there has always been a discord between your brothers, and Ling Zun favors your two brothers, my family master is worried that your Li family will fight because ......of the glass workshop in the future, and your two brothers seem to be a little too close to the three major families in Dengzhou!" Didn't Director Li know that what the three great families did was contrary to the policy of the Assassin Mansion? Therefore, the head of my family is a little worried about your Li family, which is also inevitable. ”

The three major families mentioned by Li Ren are the Li family in Dengzhou City, the Cui family in Wendeng County, and the Xue family in Muping County, these three families have always kept a distance from Li Congyan, full of vigilance, and it is said that they are also disconnected from An Chongzhi and Li Congke, so it is reasonable that Li Congyan has no good impression of these families.

Li Sisheng naturally knew which ones Li Ren was talking about, and he thought about something thoughtfully at this time, and only said after a long time: "Please join the army and return to Li Tingshi, just say that I know what to do!" ”

The words are divided into two ends, after Li Congyan returned to Dengzhou Assassin's Mansion, Sicang joined the army, Zhu Ming, who also served as Si Hu to join the army, and Wang Zuhe, who joined the army of Si Tian, hurried over, and the two brought a not very good news: some officials from Penglai, Huangxian, Wendeng, and Muping counties gathered in Dengzhou City to collectively make a statement to Li Congyan!

Li Congyan couldn't help but be stunned after hearing this: Is this a rebellion?
