Chapter 90: Knock it out loud and break it without a hole (500 monthly tickets yesterday)
"Did you see that? The extra corners here can be knocked off!"
"Ah, I asked you why there are extra pieces of corners on each one, and you thought they were burnt?"
"You are disabled, do you know why you did this?"
"Haha, I don't know, but I live streamed the room and the netizens have great powers. Is it to see what's going on inside?"
"After all, there are smart people. Historical records record that after the gold bricks leave the kiln, they must undergo strict inspection. If 6 of a batch of gold bricks cannot make a sound when knocked or break without holes, this batch of gold bricks will
Bricks are considered waste products and need to be fired again. It takes up to one or even two years to go from clay to gold bricks."
"Is there any problem in this sentence? Think about it carefully!"
"I also remember that there are historical records: Every time a gold brick is made, one main brick must be made, and one to five or six auxiliary bricks must be prepared for selection. Even so, if there is a slight carelessness in a certain link, the entire kiln will be damaged.
When scrapped, it’s often the worst.”
"Yes, you are right. A kiln brick must be broken into six pieces to see if there are no holes inside before it is considered qualified. Isn't that right?"
"History records it, it must be like this!"
"Haha, look carefully. If 6 of a batch of gold bricks cannot make a sound when knocked or break without holes, then this batch of gold bricks are considered scrap and need to be re-fired. What does this mean? What does it mean for each brick?
Every piece has to be knocked and broken. If six pieces with holes are picked out from a kiln, it means that the workmanship is not up to standard and the kiln will be useless."
"Ah? Every brick has to be broken?"
"Are you stupid? You still need to smash it? Just like me, just burn out an extra part, knock it off, and see what's going on inside? Do you really think that ancient money is not money?"
Chen Wenzhe knocked off all the extra corners piece by piece.
Then break it into pieces and examine each piece carefully to see if there are any air holes inside.
However, his master-level clay training skills are still worthy of trust.
After looking at five or six pieces, I couldn't find any with holes.
Of course, the main reason was that he only looked at the corners. As for breaking the whole piece into pieces to examine, he didn't have the luxury.
Chen Wenzhe believes that even in ancient times, craftsmen, including officials and emperors, would not be so extravagant as to break the entire gold brick to see what was inside.
The same brick embryo, with some extra corners, can be broken and looked at.
Do this all over again, and if there are no more than six pieces with holes, just use what you have!
This is the real situation in ancient times and Chen Wenzhe's real experience in his dream.
Li Qingtian felt that his intelligence had been insulted and immediately wanted to regain his face.
"Your sound is like a chime, which is barely enough. If it is broken without holes, it is considered qualified, but what about the sound as clear as a mirror?"
"This needs polishing!"
Chen Wenzhe sighed and took out all the grinders and polishers that he had prepared.
Of course, he has prepared sandpaper of various thicknesses and sizes.
This is the penultimate step, this step is polishing.
The "gold bricks" that have just been moved out of the kiln can only be regarded as semi-finished products like rough jade. To turn them into dazzling and beautiful jade, it takes a lot of effort and meticulous polishing.
In the beginning, of course, there is no need for any superb skills.
So modern tools came into use, and grinding with a grinder was very fast.
Originally, the batch of gold bricks fired by Chen Wenzhe were made with fine workmanship and there were not many uneven spots. Coupled with his incomparable touch, Chen Wenzhe felt that they were almost ready in just a few minutes.
Then replace with fine sandpaper and sand carefully.
Only when he couldn't find any injustice did Chen Wenzhe stop.
This is the time to truly perform your skills.
The tools used to polish ancient "gold bricks" were extremely simple.
It is done in a circular sink, grinding and flushing at the same time.
In doing so, not only will the surface of the gold brick be smoothed, but it will also become brighter and brighter the longer it is used, and it can even be used as a mirror.
However, after the Qing Dynasty, the polishing technology that made the "bricks" look like mirrors has been lost.
Of course, if it had not been lost, the system would not let him pass on this craft.
Holding the gold brick in his arms, he came to the sink that had been prepared and carefully put the gold brick in.
At this time, he still used fine sandpaper and slowly polished it.
"Brother Qinghu, take the prepared mud and bring it over, that is, the fine mud placed in the basin!"
“Do you need mud for polishing?”
"No need, if the mud is not controlled well, bad things will happen!"
While grinding the mirror, carefully feel the condition of the brick surface.
The newly fired gold bricks are drinking water.
This water has been specially treated by him, mainly to prevent rust.
This is a one-step distressing process, so there is no need to explain it to Li Qingtian in detail here.
As for getting some mud into the water, it is naturally for rust.
The simplest way to make bricks look old is to add some water rust and soil rust. No other techniques are needed.
As for the internal situation, who can break it open and take a look?
Therefore, Chen Wenzhe can definitely make it into the Ming Dynasty.
This does not work with porcelain, because with different aging times, a chaff-like vitrification phenomenon will occur inside the porcelain, that is, crystallization.
Chen Wenzhe's specialized distressing skills cannot accomplish this, so he cannot distress porcelain from before the Ming Dynasty.
As the inheritance of digestion increased, various skills merged with each other, giving Chen Wenzhe a clearer understanding.
Whether it's distressing or manufacturing, he has made great progress.
With modern tools, polishing a brick will definitely be very fast.
Of course, this requires superb skills and sufficient hand feel, otherwise, you will definitely not be able to polish the mirror surface.
The next step is polishing. The original ancient gold bricks definitely did not have this procedure.
After drinking enough water in Brick, it is stained with mud, especially the earthy smell, which will follow the water molecules and penetrate into the interior of the brick.
At this point, Chen Wenzhe will take the next step.
Of course, no matter which step, it takes time. For example, the polished gold bricks must be dried.
Only when it is half dry in the sun can you proceed to the next step, and this step is the simplest, which is to soak it in oil.
After polishing, the "gold bricks" should be soaked in tung oil piece by piece.
Tung oil can not only make the "gold brick" shiny, but also extend 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 soaking it in oil. The main reason is that it takes time to make it look old.
Chen Wenzhe needed to penetrate the rust and rust into the interior of the gold bricks. In this way, after some of the corners that he did not knock off were knocked off, what would appear inside would be what the ancient gold bricks looked like.
Chen Wenzhe had planned all of this a long time ago, as long as he implemented it step by step.
He believed that it would definitely surprise the experts in the city of God.
