Chapter 190

It's not easy to make leather boots.

First of all, raw animal skins should be tanned into leather.

It was the easiest step to get animal skins. In primitive society, there were many kinds of animal skins. Ye Xi gave up conventional leather materials such as cowhide and sheepskin, but chose a kind of ant eating tapir skin.

The animal's skin is more durable and more resilient.

Soak the peeled skin in a bucket for about four days. Take out the soft raw skin and clean the fat and meat foam on the skin with a stone knife. The skin of an ant eating tapir does not grow hair, so the hair removal procedure can be omitted.

Then we need to use the chemical solution mirabilite solution.

Mirabilite is a kind of sulfate mineral, which is formed naturally in salt lakes and other places. Later, Tu Shan asked the secret of Huangbo's salt production from the slaves, and knew that their tribe had found a salt spring.

Ye Xi spent a day to take some natural Glauber's salt from this salt spring and made it into mirabilite solution.

The next step is to make leather.

In the Green Valley, ye Xiqing came out of a piece of land and asked everyone to help build a stove.

Setting up a stove is a simple job. Originally, ye Xi asked ordinary men in the tribe to help, but cangpan soldiers, who knew about it, were very active in holding stones to build the stove.

"Come on, come on, let's do this. You can do something else." Cangpan squatted on the ground with a smile and built a stone stove.

Qi was half kneeling on the ground to grind the stones so that the stones could fit better. He said to the men without lifting his head: "yes, you can do other things."

Cones, minks and porpoises all pushed over with stones, pushing these ordinary men aside.

These men are not willing to go.

They finally had a chance to help Ye Xi do things. They heard that they were going to make a pair of "leather boots" that would not hurt their feet. How could they be willing to go? At the beginning, cangpan and their experience of making salt were shown off by them intentionally or unintentionally.

But cangpan and they were all soldiers of the tribe. They did not dare to disobey them, so they could only look at Ye Xi with the eyes of praying.

Ye Xiqing coughed: "I'll ask you for help later. You'll have to wait."

They were relieved.

A simple and honest man said to Ye Xi: "if you have any work, please tell me, we can do anything!"

"Good." Ye Xi nodded with a smile.

With so many people working together, the stove was set up quickly, and the fire under it was soon set up.

Ye Xi said to the simple and honest man: "now I need a stone bucket. Help me to get a stone bucket from the cave."

"OK!" As soon as the man's eyes lit up, he would go.

But at this time, a group of soldiers rushed to the cave like an arrow leaving the string, which disappeared for a while.

Men can only look at their strong back, messy in the wind.

Ye Xi shook his head, some speechless.

It's just to make a pair of boots. They look like they're building rockets.

The stone bucket was quickly taken, and ye Xi put it on the fire, and then poured the mirabilite solution into it. After the heat is heated to a temperature slightly higher than the body temperature, wring the skin dry and putting it into the pot.

A group of people around him looked serious from afar.

Looking at this scene, the cone covered his mouth with his hand and whispered to the mink beside him: "won't the fur be cooked like this?"

Mink slanted one eye cone, the voice is not audible: "do you see when ye Xi made a mistake?"

Cone was a little tired of mink's manner, and snorted in response.

Ye Xi found that the water was overheated. He said to the men waiting for him: "please help me control the fire and make it smaller."

As soon as the words fell, the men rushed to the stove and made a fire.

Cangpan, a little late, was waiting for the soldiers to stand up.

"Look at their appearance. Ye Xi told them to do it, but we won't rob them." Hulu murmured, quietly withdrawing his left foot.

Ye Xi felt the solution with his hand to feel its temperature, and constantly let the men adjust the heat, while rubbing the skin with his hands, so that the solution could penetrate into it better.

After a while, ye Xi felt that he was almost done. He took out the animal skin, spread it out on a stone slab and put it to dry in the sun.

It takes a while to dry. During this time, ye Xi went to the farmland to see the crops.

In the process of drying, a group of people gathered around the hide and curiously discussed: "it seems that the hide has been soaked so much, it seems that it is different."

"That's for sure, or is it white?" Some people scoff at it.

The cone held out a forefinger: "I want to poke it to see if the skin has softened or hardened."

Cangpan immediately slapped his hand down, rebuked: "will you be responsible for the damage?"

Awkwardly pouted, but he did not dare to poke.It was half an hour after ye Xi went to the farmland and came back.

And a group of people were still whispering around the hide.

Ye Xi pushed aside the crowd. Seeing that the hide was almost dry, he announced, "OK, let's continue."

When the stove was on fire again, ye Xi soaked the dried animal skin into the Glauber's salt solution and rubbed it repeatedly with his hands. After kneading it almost, he dried it in the air, and then put it in to soak and knead it, and so on.

This step is called "eating salt". After eating through the salt, remove the floating salt from the skin, and it will be finished.

The next thing is more luxurious behavior.

Ye Xi set up a stone basin on the stove. The stone basin was filled with oil and heated to keep the temperature of the oil slightly higher than the body temperature. Then he put the animal skin into the oil and pushed it continuously with his hands, so that the oil could penetrate into the skin evenly.

Ye Xi took the skin out of the oil pan, went to the cave, and dried it on a wooden pole which had been erected in advance, and let it dry naturally in the shade.

The hide will be tanned.

Looking at the completely different hide curiously, he asked Ye Xi, "can you make boots after it's dried?"

Ye Xi shakes his head: "still need one thing to make sole."

The sole cannot be made of animal skin. It must be thick, wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact resistant and elastic. In the past, most of the soles were made of synthetic rubber, synthetic plastics, recycled leather and even elastic cardboard.

But here, ye Xi can use natural rubber to make soles. The advantages of natural rubber soles are endless.

He remembered that he saw a rubber tree in Houlin of Ye tribe last time, so he planned to go to Ye tribe and pay some price to ask Ye tribe to sell the rubber tree to Tushan, or if not, just cut some rubber.

I believe that the Ye tribe will still sell him face.
