The driver and Xiao Hong left, the driver went to the northwest, and Xiao Hong went to the northeast. Both of their teams had five people, so they did not take away any more labor force.

Wang Yang took a deep look at the direction Xiao Hong was leaving and pursed his lips. She seemed to not care much about the potential danger and hoped she wouldn't mess around.

Returning to the granary, Wang Yang opened the bag containing white clay. He was very interested in this kind of thing and wanted to find out.

He poured the white clay onto the ground, and with a crash, large and small gravels rolled onto the ground, raising dust all over the ground.

He stepped forward and touched it. The white clay was a bit like the white paint on the wall in later generations. It was very brittle and turned into powder very easily. He knocked the stone lightly on a large stone and the stone broke into pieces.

He brought some more water, poured some powder into it, and stirred it gently.

In fact, at the beginning, he doubted whether it was lime. If it was really lime, it would be excellent and could be used to make cement and alkali.

Of course, this is definitely not lime. If it is lime, when it comes into contact with water, the heat emitted will increase the temperature of the water and turn it into alkaline water. If the concentration is enough, Wang Yang will put his hands in it and take it out.

Turn into bones.

This is naturally a bit exaggerated, but it can be completely proven that this is not lime.

After understanding this, Wang Yang didn't think much about it, but the white clay was really surprising.

After two days, the bricks made from this white clay were basically finalized. Wang Yang didn't make many. He only made ten bricks and put them in the kiln for calcining.

After firing for a day, Wang Yang felt that it was almost done. He closed the kiln and waited quietly for it to come out of the kiln.

Wang Yang has mastered the brick-making technique better and better now. At first, he was at a loss. He burned the bricks for two days, fearing that the bricks would not come out.

Later I discovered that it actually doesn’t take so long to burn. It only takes one day. This reduces the time it takes to produce bricks.

Wang Yang started the furnace the next day, which should be relatively early in time.

He doesn't particularly care.

Thick smoke dispersed along the air inlet and outlet that had been dyed black, and emerged from the ground.

Wang Yang sat aside with a bowl of dumplings, ate a few, and took a look. After he finished, he went to catch up on his afternoon nap, rested comfortably in the cool granary, and came out in the evening.

By this time, the thick smoke has dispersed, and the bricks can be removed.

Wang Yang and several adults walked into the closed air inlet. Wang Yang moved forward slowly to ensure that there was no more thick smoke.

The air inlet was originally open to the air, so you didn't feel too hot when adding charcoal, but in the rainy season, a lot of rainwater poured in along the air inlet.

I had no choice but to seal the top of the air inlet. I left a small outlet that was not too big. When it rained, I sealed the outlet.

There was some incompletely used charcoal in the passage, scattered in the corner, and no one was collecting it, making it look a bit messy.

Wang Yang took out ten bricks from the kiln without thinking too much.

Under the red afterglow of the setting sun, the surface of these ten bricks was covered with a layer of black ash. They were washed in water to reveal a white surface.

Wang Yang touched it, and surprise flashed in his eyes. The surface of the bricks made of white clay was very smooth, and it felt like touching the ice. It was very different from the rough bricks made of red clay.

It looks more like a thick piece of white hard plastic.

He picked up a brick and without thinking, he smashed it on a big rock. "Crack", the brick broke into two halves, but miraculously, there were not many debris.

It didn't look like the brick had been chewed, but rather cut, leaving a sharp edge.

The osteologist looked at it and smiled, and told Wang Yang that the quality of the bricks seemed to be better.

Wang Yang expressed doubts. If it was so good, why didn't anyone use it in his previous life? He decided to test it in another way.

I polished it on a big stone, and I was surprised to find that the white brick was like chalk, leaving white lines on the stone. The mark was very deep, and it seemed... very wear-resistant.

He was even more confused. Since it is wear-resistant and hard, it should look better than red clay bricks, but why are they not widely used?

Could it be said that there are not many reserves of this type of clay?

It was possible, after all, it was rarely seen. Then he did another test, hitting the brick with pebbles.

Pebbles are a very good thing, neither too hard nor too soft. Ordinary bricks cannot withstand the impact of pebbles.

This brick was no exception. It cracked immediately after being hit, and it cracked with just a slight hit.

Wang Yang suddenly realized that it was not all good. It was just because it was too hard that it was too brittle.

It doesn't matter whether the bricks used to build the house are hard or not, they should be just about right, but they should not be too brittle, otherwise the quality will be inferior.

But having said that, there should be no problem in building a house with these bricks. As long as there is enough clay, they can be manufactured in large quantities.

Suddenly, he thought of something. Would it look better if he used this white clay to make ceramics?

I just did it as I thought, and a few days later, a batch of exquisite white ceramics appeared.

Wang Yang made an estimate and estimated that these white clays are important raw materials for making those ceramics. After all, the color is beautiful and the surface is smooth. As long as the technology is better studied, it will be very beautiful.

Maybe in ancient times, these white clays were specially used for making ceramics by the royal wealthy.

The matter of making bricks and ceramics was put on Wang Yang's agenda. The most important thing now is the source of food, which has been properly arranged.

The second most important thing is to find other human beings, increase productivity, and expand horizons. Arrangements have also been made.

Thirdly, building a relatively complete habitat is also very important.

He called everyone, and an adult who usually followed the team of expellers was specially kept by Wang Yang, asking him to select some people to transport clay, and then arrange for others to bake bricks in preparation for building houses.

He didn't care about the main purpose of the white clay, no matter what kind of objects it was more intended to make, he would use it first anyway.

Finally he began to prepare the tools for purifying the salt.

As mentioned before, his purification is not the high-demand purification in the laboratory, nor does it require any chemical principles. The purification he does is only to eliminate the number of impurities in the salt, at least not to eat sediment into the stomach.

Therefore, any normal person can achieve his purification.

Just then the wooden barrel made by Zhang San arrived.

This wooden barrel has a large capacity and was taken from a very large tree, with a diameter of at least three meters.

And according to Wang Yang's request, there are several small holes two fingers thick at the bottom of the barrel, which serve as openings for filtering.
