Daming: In the beginning, he mistakenly regarded Emperor Yongle as his own father

Kindly treat it as the liver and lungs of a donkey.

When Yang Shiqi heard this, he immediately got angry.

What should we do? If we don't stop it, Lu Lin will be doomed.

Chapter 46

Lu Lin didn't know the calculations and worries of Xu Guogong and others.

All my mind is on the salt mine.

This side ordered people to mine salt mines, and Lu Lin couldn't wait to go back to the house to prepare salt-making tools.

It is said to be a salt-making tool, but it is actually just a set of simple filtration and distillation devices. I have learned chemistry in junior high school before.

The reason why poisonous salt cannot be eaten is because there are a lot of toxic minerals in poisonous salt.

However, many of these toxic minerals are insoluble in water. As long as they are filtered several times and then distilled out, they can basically be detoxified.

However, this time the amount of poisonous salt was large, so he purposely built a large device to facilitate the extraction of more edible salt.

After the salt mine entered the mansion, he ordered his servants to break the large salt blocks into as small grains of sand as possible.

Then put the salt grains into a stone mill, grind them into powder, and then put them all into wooden barrels.

Soon, a dozen buckets of yellowed salt powder were carried into his newly opened laboratory.

Now it's time to filter.

First add water to the wooden barrel, stir, let the salt dissolve in the water, after the dissolution, pour the water into another prepared wooden barrel with three or four layers of filter cloth.

A bucket of water came down, and the filter cloth was covered with gray-black, water-insoluble minerals.

Lu Lin glanced at the water that had been filtered for the first time, and it was still yellow, but the color was obviously lighter than the yellowish brown just now.

But far from edible.

So repeat the previous steps again, filter.

After this cycle for about three or four times, the yellow impurities are basically invisible in the water.

Next is detoxification.

There are many ways to detoxify, and the Ming Dynasty had its own detoxification method.

But the cost is too high, and detoxified materials are more expensive than table salt, which is why many people are unwilling to produce table salt even though they have salt mines.

It's all a loss-making business.

The reason why Uncle Lu pushed him to mine the salt mine was because he knew it was a loss-making business.

Who doesn't seem to know.

But apart from the expensive detoxification methods of the Ming Dynasty, Lu Lin has the most primitive and effective charcoal detoxification method.

Grind the charcoal into powder, cover it on the filter cloth, and then cover it with a layer of filter cloth to cover the charcoal.

About four layers of charcoal powder will do.

Charcoal can absorb toxic substances in water, but it will not absorb edible salt dissolved in water.

Because of the addition of charcoal, the filtration will be very slow. Lu Lin specially made dozens of large funnels, poured all the water into it, and waited overnight for it to filter slowly.

When I got up early the next morning, the water below the leak was basically clear salt water without debris.

He tasted it with his finger. It was very salty, but not bitter.

Proved to have been completely detoxified.

The final step is distillation.

Set up a large iron pot and burn wood to evaporate the water directly.

After boiling for about 2 hours, all the food has been precipitated.

The flakes of white flowers stick to the bottom of the pot.

Salt was made, but no one believed that the salt was edible.

The servants whispered even more.

"The master really dares to do anything, he dares to make poisonous salt, and he is not afraid of eating dead people."

"Isn't it? I heard that the master's father has already persuaded him, so he insisted on not listening."

"If so much poisonous salt is produced, if it is sold, the family will be ransacked and exterminated."

"Let's pay our wages and leave before the poisonous salt is sold. We can't risk our lives."

Yu Qian was very angry when he heard his servant arrange Brother Lu in such a way.

But he didn't scold them, because he knew it was useless, what really worked was telling them with actions that the salt was edible.

So Yu Qian stepped forward silently, broke off a small piece and put it in his mouth, with a heroic appearance.

But the next moment, he suddenly froze, and the hand holding the salt trembled violently.

"Salt, it's salt, it's really salt."

It is finer and saltier than the official ones.

With a snarl from Yu Qian, the whole Lu Mansion trembled three times.

When the other servants heard that fine salt had really been made, they were shocked and froze in place.

what?

Really fine salt?

Not poisonous?

The next second, suddenly a swarm of bees gathered around, one of them dug a little bit, and put it in his mouth to try it out.

salt.

Really salt.

No impurities at all.
