It took a little time, everyone will make fish feed raw materials collected completely, grinding, fermentation, a lot of people, work naturally fast, only a few hundred catties of bean dregs, soon packed in several large pots, sealed fermentation.

"Stay at home, Guo Du, let's go to the market."

"Brother Yuan, go get busy, there's nothing to do at home now, with us." Meng Ying said with a smile.

"Luoluo, you take Xiaoya to play more, see when Xiaobao has a holiday, call him to play, some of the things you brought back this time, Xiaoying, you take the time to send some to your father-in-law."

"Okay, Brother Yuan." Meng Ying said sweetly in her heart.

There is nothing to do at home, and there is very little farm work, this time I brought back some vegetable seeds from the county seat, which need to be planted in the vegetable field, and in the wheat field, there is some grass, but Jia Yu's family has pulled out the grass growing in the field very cleanly, and it has become the ration of the livestock and poultry at home.

"Do you want to catch a carriage?" Guo Du asked.

"Hurry." Zhao Yuan nodded and said.

When he came to the market, Zhao Yuan went to the small supermarket to take a look around, learned about the operation of the supermarket, and walked directly to the Li family's store.

The Li family is an old wealthy family in Gray Plains Town, and the pottery craftsmanship passed down from the ancestors has been passed down for three generations.

Li's father's name is Li Ziqiang, when Zhao Yuan came to Li's shop, Li Ziqiang and his son Li Yun were not there, and they asked a guy to inquire, they were in the Li family kiln, and Zhao Yuan and Guo had to go to the Li family kiln.

Lijia kiln, located at the foot of the north mountain of the old mountain, there is a large area of clay ore here, after the development of the Li family for three generations, the entire clay deposit is only a small part.

Clay ores, which contain mainly claystone and soil, are hydrous silicate minerals containing aluminium and magnesium.

Zhao Yuan and the two drove the carriage towards the Li family kiln, and from a distance, they saw the smoke of the ceramic kiln in the kiln.

"Let's walk over there." Coming to the outside of the Li family kiln, Zhao Yuan looked at the thin mud in the field and said to Guo Du.

Because of the rain last night, the Li family kiln was particularly muddy, and at this time, there were workers stepping on the mud in the mud field, which was one of the particularly important processes.

In the era when there was no machine to help, most of the operations had to be carried out manually, and stepping on mud was also called stepping on tiles. The roads in the countryside are generally muddy, and people will say that they are stepping on the mud when they walk to describe the difficult road, which is the work that the workers of the Lijia kiln are doing now.

"Excuse me, is your boss Boss Li here?" Zhao Yuan cautiously walked up to the workers and asked loudly.

"Are you here to find the owner, they are watching from the kiln." The mud stomper said.

"Yes, let's find Boss Li."

"It's a custom pottery, you go to the back and find the owner."

"Sort of, master, you are busy first." Zhao Yuan nodded with a smile, and walked towards the place where the kiln was fired behind him.

Don't look at the fact that every household will use clay bowls, clay pots, and jars, but it is not easy to turn clay ore into these commonly used things.

Zhao Yuan all the way, you can clearly see most of the process of pottery, combined with the knowledge in his mind, although there are still many flaws in the process of the Li family, but it is worthy of three generations of ceramics, the process has been very mature.

"Master, don't you use clay to make ceramics, why are there so many stones piled up in this kiln?" Guo Du asked.

"It's not any stone, it's clay ore." Zhao Yuan said with a smile.

The Li family makes porcelain relatively little, generally firing pottery, the selection of clay ore does not need to be very fine, but the steps of practicing mud are indeed indispensable, a row of sheds where the clay ore is contained, there are a lot of stone mortars, at this time there are workers to smash the clay ore with a hammer, put it into a stone mortar into powder, and then wash it with water to remove impurities.

There are many processes of clay, drawing, drying, printing, refurbishment, firing, and step-by-step pottery, which makes Zhao Yuan sigh that there has been thousands of years of magic in the ceramic manufacturing process and admires the wisdom of the ancestors.

"Boss Li, I'm bothering you again." Seeing the Li family father and son who were looking at the kiln in front of a ceramic kiln that was still hot, Zhao Yuan stepped forward and said hello.

"Boss Zhao has come back from the county seat, you are a rare guest." Li Ziqiang said with a smile.

"I just came back yesterday, and I didn't expect Boss Li to make a small clay pot from Boss Li last time."

"Boss Zhao has seen it, how is it, are you still satisfied?"

"Satisfied, Boss Li's craftsmanship in making ceramics is this."

Zhao Yuan gave Li Ziqiang a thumbs up.

"Boss Zhao is here to make some more?" Li Ziqiang's eyes lit up.

"No, I came to Boss Li to buy clay ore from you for a long time." Zhao Yuan said.

"Boss Zhao is going to build a ceramic kiln?" When Li Ziqiang heard Zhao Yuan's words, he frowned and said.

"Brother Zhao, it's not a simple matter to burn ceramics." Li Yun also said on the side.

"I want clay ore, not to make ceramics, but to make a new building material, something called cement." Zhao Yuan said with a smile.

"Don't hide it from Boss Zhao, the clay ore here in our Li family kiln is not for sale, although there are a lot of clay ores here, but this is the foundation of our Li family." Li Ziqiang shook his head slightly and said.

"Yes, Brother Zhao, our Li family has ancestral teachings, clay is our foundation, and this kiln is to be passed on to future generations."

"Well, I'm abrupt." Zhao Yuan said with a smile.

It seems that it is still unrealistic to obtain clay from the Li family, so I can only look everywhere to see if there are clay mines in other places.

In the firing process of cement, the proportion of clay accounts for about 15%, which is very important for the production of cement. There is also a need for about five percent of iron ore, which is not a big problem for Zhao Yuan, who has a large number of mineral deposits in his mind, to find a good iron ore in Shudi.

However, because of the wide distribution of clay ore, except for a few well-known production areas, later generations have not marked the production areas of each small place.

"This won't work, Boss Li, my workshop is waiting to start, before we find a new clay mine, buy some clay ore from you first, rest assured, the amount will not be very large, and it will not affect the ceramics and other firing you have here." Zhao Yuan said after thinking about it.

"Okay, that is, Boss Zhao, if it were someone else, I wouldn't let go." Li Ziqiang and his son glanced at each other, nodded and said.

"Thank you so much." Zhao Yuan said with a smile.

Because there would not be a lot of clay ore to buy from the Li family kiln, Zhao Yuanzhi didn't care about the price, and set a thousand quintals of clay at the price of ten cents per load of clay.

A quintal of clay ore is almost a hundred liters of the unit of measurement of later generations, that is, one hundred-point one, and one thousand quintals is almost a hundred cubic meters of clay ore, which should be enough for the trial production of the cement workshop in the early stage.

After talking about the clay, Zhao Yuan bought a few new fine porcelain from the kiln here in the Li family kiln, according to Li Ziqiang and his son, they are preparing to launch a new product, which will be put in the future generations, and it is an antique.
