Zhao Kuan stood quietly.

Fu Tinghan understood at a glance, "You can't find a craftsman?" ”

Zhao Kuan sighed and said, "Shangshu, it's not that I'm prevaricating, but I really can't find it." ”

Now anything in Qingzhou is more important than studying the salt drying method, and Dajin is not without salt, but it is a little more expensive, and he thinks he can start later.

However, Fu Tinghan came over in person, and with the general's attention to him, this salt administration is only afraid that there is something else.

Zhao Kuan thought about the people he could use now in his mind, and said, "I asked people to look for craftsmen who could cook salt in various counties. ”

At present, salt is still mainly obtained by boiling.

However, there is also a technique for boiling salt, not pouring water into the pot, just blindly burning the fire, so they have to find technicians.

Of course, boiling salt is not difficult for Fu Tinghan, but now that time is tight, he really doesn't want to find newcomers to teach him one by one.

However, now that the people of the states are wandering around because of the scourge of war, most of the craftsmen recorded in the records are not in their hometowns, and it is indeed not easy to find them.

Fu Tinghan thought for a while and said, "Craftsman, you can find it for the time being, and then find me a hundred trustworthy and strong young people, and I will teach them to boil and dry salt." ”

Zhao Kuan responded, but expressed doubts about Fu Tinghan's method of writing on paper, "Shangshu, can the sea really produce salt?" ”

Soon, the two salt-boiling craftsmen that Zhao Kuan found gave him an answer, saying: "Seawater drying can indeed produce salt, but the salt can't be eaten, and people will die if they eat it." ”

Of course, they didn't die immediately, but they lived by the sea for generations, and their ancestors occasionally found that when the sun was exposed, there would be white grains on the beach, and they knew it was salt when they touched it.

Therefore, the ancestors secretly tried to dry salt in seawater, but the salt that came out was very bitter, and it was difficult for people to swallow, and they would be poisoned and die after eating it for a while.

So they refuse to dry salt.

However, Fu Tinghan insisted on drying salt.

The craftsman and Fu Tinghan, Zhao Kuan naturally believed in Fu Tinghan, so he directly handed over the two craftsmen he had finally found to Fu Tinghan, as well as the one hundred young men selected.

Fu Tinghan took them to live in an abandoned small fishing village by the sea, which is very convenient, not only the tidal flats are flat and open, but also Gwangju next door.

When Sun Linghui heard that Fu Tinghan had arrived, she immediately selected a hundred young men and brought them over to him.

Regardless of whether the salt drying method works or not, anyway, it is always right to hand it over to Fu Tinghan, and it is always right to learn skills from him.

What Qingzhou has, she also has in Gwangju.

Seeing that Sun Linghui led people to cross the boundary directly to Qingzhou, and asked Fu Tinghan to open a few salt pans to test on the tidal flats next door, Zhao Kuan couldn't help but say: "Sun Tingshi, why are you in such a hurry, the salt drying method has not been skimmed yet." ”

Sun Linghui smiled, "I never doubted Fu Shangshu's ability. ”

Zhao Kuan glanced at Fu Tinghan, who had the corners of his mouth slightly upturned, and secretly cursed in his heart for "sycophancy", and then immediately said: "Third brother-in-law, I also believe in you." ”

The corners of Fu Tinghan's mouth were more curved, and even there was a smile between his eyebrows, "I still need something, and I have the help of Lao and the two thorns to find it." ”

He was also very impartial, and one person gave them a piece of paper, and the contents of the paper were still the same, and they looked at it, and it was the same as the recipe they had obtained when they left Chen County, which asked for all kinds of strange things, such as barite, which was not uncommon on the seaside, and found a large piece of rock in the area of the shallow sea.

Fu Tinghan said: "These things are not valuable, and they will need a lot in the future, so the more the merrier." ”

Zhao Kuan and Sun Linghui glanced at each other and nodded.

It's so busy, Fu Tinghan came here not only did not reduce their workload, but also increased.

The two of them went down to arrange sadly.

Fu Tinghan began to lead people to build salt pans.

He took people all over this river beach, in order to increase the contact area between salt water and air, increase the evaporation area, and strengthen evaporation, Fu Tinghan also arranged it in each salt field.

In order to prevent any disputes between Qingzhou and Gwangju in the future, he treated them equally, and the 100 people they sent were used for their own tidal flats, and even the number of tidal flats developed was the same.

At this time, it is actually not very suitable for drying salt, after all, the weather is starting to turn cold, and Fu Tinghan also knows that he is still mainly researching here.

Fu Tinghan led the young men to dig out the trench, and every time the tide rises, the seawater will pour into the trench, opening the pass of the salt pan, and the sea water in the trench will pour into the salt pan.

Qingzhou and Gwangju have less rain, more sunlight, and strong winds, so even if the temperature is slightly lower at this time, the sea water is still evaporating rapidly under the sunlight and the wind, especially Fu Tinghan also makes people regularly stir to increase the contact area between salt water and air, and the evaporation is faster.

The brine from the first zone is placed in zone 2, and when it is dried in zone 2, zone 1 is leveled again and then put in brine, and when the brine in zone 2 evaporates more thickly, it is put into zone 3, and then the sea salt is dried for the second time and enters zone 2......

In this way, all the hundred people given on both sides were not allowed to be idle, and the speed was very fast, and the salt pans were precipitated with gray-white and gray-yellow crystals.

After Zhao Kuan heard about it, he ran over to see, and after not seeing him for more than 20 days, he lost some weight, and his beard covered half of his face, making him look even darker.

Although Fu Tinghan was also dark, he didn't make himself look like this that no acquaintance could barely recognize.

Zhao Kuan squatted on the edge of the field, grabbed a handful of sea salt that had been piled up into a hill, and asked, "Is this okay?" ”

Fu Tinghan glanced at him and said, "Not yet, this is coarse salt, I need to dissolve and filter the impurities again." ”

Fu Tinghan uses two methods to filter coarse salt, one is to dissolve coarse salt with proportioned materials and then filter and then dry the salt, and the other is to dissolve it with water, stir it and filter, and then precipitate out sea salt.

He wanted to see which method was faster and better, and maybe a combination of the two when the time came.

Zhao Kuan looked at the coarse salt like a hill in each salt pan and was amazed, "If the salt dried in this way is really edible, the price of salt will ...... in the future" Isn't it a diving price?

Zhao Kuan's heart trembled, and he had a feeling that the world was about to change.

Cheongju and Gwangju may be in a whirlpool.

Zhao Kuan patted off the salt in his hand, and said to Fu Tinghan with a serious face: "Shangshu, just tell me what you need in the future, as long as I can find it, I will definitely find it for you." ”

"Shall I send you another two hundred? I think there are a few people in this salt farm, and the sea water is the same for such a large piece over there, so it should be possible to produce salt. ”

Fu Tinghan can even make colored glass, isn't it easier to dry salt than to make colored glass?

Zhao Kuan felt that his confidence in him before was still not big enough, and he could have been a little bigger.

"If two hundred people are not enough, I will recruit you more, and you can ask as many as you want."

Fu Tinghan asked: "Our grain and grass are in arrears for two days, can you afford to raise another two hundred people?" ”

Zhao Kuan wiped his face and said, "I'll let someone send you grain and grass, and the people who make up for it will also make up for it."

He gritted his teeth, big deal, he sold something and bought some food with the passing merchants.
