I was a village chief in a primitive society

Chapter 241: Plant ash cement production. (4 more please customize)

"crackling......"

The flames in the kiln grew stronger and stronger, and a large pile of hay was burned in a short time.

And every time after a pile of hay is burned, the ashes under the kiln are collected and put in a wooden barrel.

In more than an hour, more than ten barrels of plant ash have been placed next to the kiln.

"Wu, all the hay has been burned, and the ashes inside have been collected."Yanjiao came over.

"Let someone prepare some water, the more the better, and bring it from the pool."Su Bai ordered.

He stepped forward and reached into the barrel to check the ashes. Fortunately, there was almost no charcoal in the perfectly fired ashes.

"yes." Yanjiao immediately asked the slave to continue fetching water.

Ten minutes later, the dozen buckets of water fetched by the slave were placed next to the kiln.

Su Bai didn't say anything, but just set an example by himself. A bucket of ashes and a bucket of water were put together.

He put all the ashes in the bucketin the water, then picked up a wooden stick and started stirring, trying to stir them until they were even.

Yanjiao and Fox-Eared Girls all stood aside quietly, looking at Su Bai's operation in confusion.

After Su Bai stirred the plant ash water evenly, he slowly held the wooden bucket and began to drain the water inside.

This action is to drain out the water containing potassium carbonate in the plant ash water, and then retain the insoluble calcium hydroxide and calcium carbonate paste.

These two things are the most important things for making plant ash cement. Without these two things, there is no way to make plant ash cement.

After Su Bai slowly poured out the water in the bucket, he looked at the paste inside the bucket and wanted to make sure it was qualified.

After making sure it was what he wanted, he started to grab a piece of plant ash and hold it tightly to drain out the excess water.

Repeat this action several times until the plant ash in the barrel is completely removed.

Yanjiao looked at the ash balls of vegetation on the ground and wondered,"Witch, is this cement?"

"It doesn't need to be processed for the time being. You can have people start lighting the fire in the kiln."Su Bai ordered.

Making plant ash cement is not that simple. The next step is to use fire to burn it into a yellow hot state.

How did the chief know this? He immediately asked people to continue to light the fire, and then put out all the plant ash balls. go in

"crackling......"

The fire in the kiln was burning brightly, and the ashes of the vegetation slowly turned into yellow heat.

"Okay, take out all those grass and tree ash balls and let them cool down."Su Bai ordered

"yes."The slaves nodded.

Ten minutes later, Su Bai waited until the grass and vegetable dumplings had completely cooled down, and then he put the dumplings into a new bucket of water.

Let the dumplings begin to slowly disintegrate in the water, and then He took a wooden stick and started to stir them together.

Su Bai took out a bucket of sand and gravel that he had asked them to prepare before. These are also important binders.

He mixed the dissolved grass and tree dumplings with these fine sand and gravels. The stones slowly fused together, and then began to stir.

The first time, because there were too few gravels and sand, Su Bai added a little more and continued to stir evenly.

After ten minutes, all the grass and tree dumplings and fine sand were gone. It blended together, and it looked like cement.

Su Bai picked up two stones, smeared a lot of grass plaster on the front of one of the stones, and then placed the other stone on the side with the grass plaster.

Make sure that the two After the stones were stuck with vegetation and plaster, he went to wash his hands clean.

"Wu, is the cement ready to be made?"Yu Ying asked curiously

"It doesn't look simple, but it's not difficult at all. Are these things used to build houses?"Yanjiao said doubtfully.

He had seen all the operations just now and had no other thoughts except a little doubt.

"Wait for an afternoon. If the two stones can not separate, the cement will be made."Su Bai explained.

Yanjiao squatted in front of the two stones curiously, looking at the two stones curiously. His red eyes were full of question marks, and he resisted the desire to touch them. Time passed. A second passed, it was already sunset, and the two stones had been exposed to the sun all afternoon.

Su Bai came to the two stones, reached out to touch them, and found that the two stones had been glued together.

He put the stones He picked it up and said with satisfaction:"I didn't expect it to be successful the first time."

Just in case, Su Bai threw two more stones on the ground, and found that they were not disconnected immediately, but remained in their original state.

To be more sure of success, he put the two stones in again In the water, I wanted to see if the plant ash cement would dissolve.

It turned out that the two stones were still firmly bonded together and did not dissolve when exposed to water.

"Great, this time it really worked."Su Bai nodded with satisfaction.

Yanjiao saw all this scene, and finally found that the two stones were still glued together, and was very shocked.

He calmed down his emotions and asked:"Witch, this is cement ? so amazing!"

This was the first time he saw two stones stuck together, but it had nothing to do with witchcraft.

"This is cement, the artifact for making houses."Su Bai is also very satisfied.

"I thought it was witchcraft, oh my god."Yu Ying said in surprise, her pink eyes blinking.

"This is the power of nature and does not require witchcraft."Su Bai smiled.

Yanjiao kept looking at the two bonded stones, his red eyes full of surprise.

He kept holding the two stones in his hands and looking at them, and kept mumbling about the magic.

Others also Same, I was particularly fascinated by it, and I respected Su Bai's feelings even more..........................................
