My system is not decent

"See? The extra corners here can be knocked off!"

"Ah, I said why one by one, there are extra pieces of corners, and I thought it was burnt?"

"You are disabled, do you know why you did this?"

"Haha, I don't know, but the netizen in my live broadcast room is supernatural, so I can see what's going on inside, right?"

"Finally, there are smart people. According to historical records, after the gold bricks come out of the kiln, they have to go through strict inspection. If there are 6 pieces in a batch of gold bricks that cannot be knocked soundly and broken without holes, this batch of gold bricks will be broken. Bricks are considered waste products and need to be fired again, just like that, it takes as long as a year or even two years from clay to gold bricks."

"Is there any problem in this sentence? Think carefully!"

"I also remember that there are historical records: every time a gold brick is made, there must be one to five or six auxiliary bricks for selection. Even so, if there is a slight carelessness in a certain link, it will cause the entire kiln The scrapped, often out of ten."

"Yes, you are right. For a brick kiln, you have to break six bricks to see if the inside is broken without any holes. Only then can it be considered qualified, isn't that true?"

"Historical records, it must be so!"

"Hehe, look carefully. If there are 6 gold bricks in a batch that cannot be knocked soundly and broken without holes, this batch of gold bricks is considered waste and needs to be re-fired. What does this mean? One piece has to be knocked and broken, and if six pieces with holes are picked out of a kiln, it means that the craftsmanship is not up to standard, and the kiln will be scrapped.”

"Huh? Every brick has to be broken?"

"Are you stupid? You still need to smash it? Just like me, just burn some more, knock it off, and see what's inside? Do you really think that ancient money is not money?"

Chen Wenzhe knocked off all the excess corners one by one.

Then smash it, and check it carefully piece by piece to see if there are air holes inside.

However, his master mud training skills are still worthy of trust.

After looking at five or six pieces, I didn't find any one with air holes.

Of course, the main reason is that he only looks at the corners. As for breaking and checking the whole piece, he doesn't have the luxury.

Chen Wenzhe believes that even in ancient times, those craftsmen, including officials and emperors, would not be so extravagant. They would break a whole piece of gold bricks to see what's inside.

The same brick embryo has some extra edges and corners, just smash it and have a look.

Do it all in this way, and the ones with pores do not exceed six yuan, so let's make do with it!

This is the real situation in ancient times, and it is the real experience of Chen Wenzhe in his dream.

Li Qingtian felt that her IQ had been insulted, and she immediately wanted to save face.

"Your sound is like a chime, barely enough, even if you have no holes in it, you are qualified, but what about the sound like a mirror?"

"This needs to be polished!"

Chen Wenzhe sighed, and took out all the grinding machines and polishing machines that he had prepared earlier.

Of course, he has all kinds of fine and coarse sandpaper ready.

This is the penultimate step of the process, this step is grinding.

The "golden bricks" that have just been moved out of the kiln can only be regarded as semi-finished products like uncut jade. To make it into a radiant and beautiful jade, it takes a lot of effort and careful polishing.

At the beginning, of course, no superb technology is needed.

So modern tools come in handy, using a sander to polish it very quickly.

Originally, the batch of gold bricks fired by Chen Wenzhe were meticulously crafted without much unevenness, coupled with his invincible hand feel, within a few minutes, Chen Wenzhe felt almost the same.

Then change to fine sandpaper and polish carefully.

Chen Wenzhe stopped when he couldn't find any injustice.

At this time, it is the moment of real performance technology.

The tools used to polish the ancient "bricks" are extremely simple.

It is carried out in a circular sink, while grinding and flushing.

In this way, not only the surface of the gold bricks will be smoothed, but the longer it is used, the brighter it will become, and it can even be used as a mirror.

However, after the Qing Dynasty, the polishing technique that made the "golden brick" look like a mirror has been lost.

Of course, if it hadn't been lost, the system wouldn't let him pass on this skill.

Holding the gold brick in his arms, he came to the sink that had been prepared earlier, and carefully put the gold brick in it.

At this time, he still sanded slowly with fine sandpaper.

"Brother Qinghu, grab the prepared mud and bring it here, that is, the fine mud put in the basin!"

"Do you still need mud for grinding?"

"No need, if the mud is not well controlled, it will cause bad things!"

While grinding the mirror, carefully perceive the condition of the brick surface.

The newly fired gold bricks are drinking water.

And the water was specially treated by him, mainly for water rusting.

This is a one-step old-fashioned process, so there is no need to explain it to Li Qingtian in detail.

As for getting some mud into the water, it is naturally for rusting.

The easiest way to make bricks old is to add some water rust and earth rust, no other techniques are needed.

As for the internal situation, who can break open a piece to see?

Therefore, Chen Wenzhe can completely implement it in the Ming Dynasty.

This is not the case for porcelain, because the aging time is different, and there will be a phenomenon of bran-like vitrification inside the porcelain, that is, crystallization.

This point, Chen Wenzhe's professional old-fashioned technology, can't do it, so he can't make old porcelain before the Ming Dynasty.

As more and more inheritances were digested, various skills merged with each other, giving Chen Wenzhe a clearer understanding.

He has made great progress no matter how old he is or how he manufactures.

With modern tools, sanding a brick can be fast.

Of course, this requires superb technology and sufficient hand feel, otherwise, the mirror surface will definitely not be polished.

The next step is polishing. The original ancient gold bricks definitely do not have this procedure.

After the gold bricks are full of water and contaminated with mud, especially the earthy smell, it will follow the water molecules and soak into the inside of the bricks.

At this point, Chen Wenzhe will proceed to the next step.

Of course, no matter which step takes time, for example, polished gold bricks must be dried.

The next step can only be done when it is half-dried in the sun, and the easiest step is to soak in oil.

After polishing, the "bricks" should be soaked in tung oil piece by piece.

Tung oil can not only make the "golden brick" shiny and bright, but also prolong its service life.

At this point, the entire process from soil to gold bricks is considered complete.

Of course, after grinding the mirror, there is no technical content in oil soaking, mainly because it takes time to make it old.

Chen Wenzhe needs to infiltrate water rust and earth rust into the interior of the gold bricks. In this way, some corners that he did not knock off, after being knocked off, will show the appearance of ancient gold bricks.

Chen Wenzhe had already planned all of this, as long as he carried out it step by step.

He believed that the experts in Shendu would definitely be surprised by that time.
