The average audience naturally knows very little.

But at the moment.

Listen to the detailed explanation of relevant professionals.

Everyone also realizes that this technique is not easy!

Don't underestimate tanned leather.

Even if it is a good leather.

if not carefully processed.

The effect of using it will be unbelievable!

And even more unexpected.

Furs can be seen everywhere in everyday life.

There are still unknown top craftsmanship!!!

【It seems that Master Kui can not only develop heavy industry!】

【Light industry is also within your grasp!】

Fresh leather.

Apply sea salt.

It can guarantee the fresh skin state of the raw skin to a great extent!

Not only can it prolong the shelf life of the leather.

It also ensures that the fibrous web under the skin is not damaged.

To achieve the purpose of protein aggregation in meat.

Convenient after soaking.

Remove debris from the skin!

in the live room.

The audience was shocked.

Jiang Kui has coated the inside of the bear skin with sea 720 salt.

Until it was confirmed that every blood stain and residual meat residue was covered with sea salt.

It's over.

then.

He took out the knife.

Make a small slit in the four corners of the leather.

Find four more small sticks.

penetrate into it.

Plunge into the ground to fix it!

Take a whole huge bear skin.

propped up.

At this moment.

Just wait a while.

When the salt above dissolves and the moisture in the meat is sucked out, the second step of tanning can be carried out - soaking in water!

Flesh is a colloid.

At least it's colloidal.

It will coagulate when encountering electrolyte solutions, heating, and electrolytes with opposite electrical properties!

This is why the addition of sea salt particles can make the residual flesh and blood colloid particles aggregate into larger particles.

Thereby a precipitate is formed and precipitated out of the dispersant!

This action is similar to alum in modern tanning agents.

The effect is actually about the same.

but.

Sea salt tanning is indeed an ancient technique known to humans trying to obtain good leather!

It was first used by the Inuit to process handcrafted raw materials such as fish skins.

Later spread to northern Europe.

Favored by Vikings.

These Vikings.

Everyone is a leather maker!

Weapons, shields, equipment used.

Even daily necessities are inseparable from animal fur.

The spread of ancient tanned leather.

Greatly improved their (bjfh) production life.

So that he becomes brave and good at fighting!

later.

It was not until the invention of vegetable tanning agents that it gradually disappeared from the stage of history.

while waiting.

Jiang Kui took out the wooden tub that he had made when making paper.

Got some water.

Set aside for later use.

Then.

Take four more sticks.

Based on the length of the fur.

Two by two as a group.

Stand on each end.

Connected with rattan ropes.

Made two simple clothes drying rods.

Subsequently.

He brought another bundle of firewood.

Lay it under the two clothes rails.

Take the fire and light it.

Wait until the bonfire burns out into a dark red charcoal fire.

Just put the dipped, degreased and washed leather on the clothes rail for drying and drying.

within a few hours.

The fibers in the skin can become very tight.

Even if it is used for several years or decades.

Will not shrink or deform.

soon.

About an hour has passed!

Arrange clothes rails for drying leather.

Jiang Kui boiled a large pot of boiling water.

then.

Again find the tub from which the paper was beaten to the pulp.

Clean up any scraps inside.

Get clean water.

Set aside for later use.

Everything is ready here.

He turned around again and came to the leather.

Observed carefully.

now.

After an hour of marinating.

Residual flesh under the skin.

Great color change.

A lot of blood flowed out.

Status and Color.

All pretty good.

see.

He hurriedly removed the stick that supported the leather.

Take a large bearskin.

Drag to the bottom of the reservoir.

Start by dipping a small portion into the tub.

Then add some water to it.

Take out the knife.

Keep shaving inside your skin!

"Shhhhh-!"

The purpose of soaking is to restore the raw skin to its fresh state again.

Facilitates the removal of partially compatible proteins.

Blood-stained feces and other debris.

usually.

The temperature of immersion depends on the type of raw skin.

Generally 15-18C is appropriate.

For example, the softening of the skin below 18C is slow.

Bacteria above 20C are easy to multiply!

Ordinary salt peel or salt dry peel.

Soak in running water for 5-6 hours.

For dry or salt-dried skins that have been stored for a long time.

It should be softened by physical or chemical methods during soaking!

If it is fresh leather.

According to the degree of softening.

Just be random.

But the water temperature must be controlled!

must remain within the appropriate range.

Otherwise, it will seriously affect the production.

Second.

In order not to damage the hair roots.

when shaving.

Jiang Kui is also extra careful!

Because shaving is closely related to the next step of degreasing!

If there is a lot of residual fat.

It is not good for degreasing!

Besides.

The reason for using a knife to deal with the residual blood and meat residue.

It can also be squeezed.

The residual fat in the skin is raised to the surface of the skin.

Better for degreasing!

soon.

Repeat this.

More than two hours passed.

at this time.

Fat adhering to the meat surface, residual meat, etc.

It's all been cleaned up.

"Hoo! 35

Look at the mess and blood on the ground.

Jiang Kui was relieved.

He moved his stiff shoulders.

Get up and take out the soap.

Ready to use saponification.

Degrease the skin!

The quality of the fur product depends on whether the degreasing is complete!

during the degreasing process.

Fat should be shed.

Does not damage the fur.

The saponification method is more moderate.

The principle is to use alkali and oil to generate soap properties.

Get rid of the oil from the coat!

For Jiang Kui.

This is the most convenient and cost-effective method at the moment!

Soap is not as good as soda ash though.

But the advantages are very obvious!

That is, without considering the ratio.

No matter what kind of leather.

Can be killed!

The reaction is relatively stable!

How to operate.

The end result is no different!

Take a break.

Jiang Kui fixed the bear skin directly under the water pipe.

Then, grab the soap.

The inside of the bearskin is covered with a thick layer of foam!

Until the peculiar greasy smell of fur is removed.

At the same time, the bubbles do not disappear!

When seeing the bubbles no longer disappear.

This means that the skin has been degreased!

at this time.

Degreasing fur.

Should be washed immediately.

Remove the soapy liquid!

Notice this scene.

Jiang Kui hurriedly turned on the faucet of the reservoir.

Rinse off the soap on the skin!

Now look at the inside of the bear skin.

It has become very delicate!

Compared with the dirty and blood-stained appearance just now.

Absolutely heaven and earth!

here.

The entire ancient method of tanning is completed.

After drying and baking.

Then apply beeswax maintenance.

Ready to make a bed!
