When the kiln was being fired, Chen Wenzhe's most important job was to see what was going on inside the kiln through fire photos.
The porcelain was all placed in the sagger, but he actually couldn't see anything, and what he saw was not porcelain.
At this time, the temperature of each location in the kiln can be judged mainly through the color of the flame in the kiln.
Although he installed a lot of sensors inside that allowed him to see the temperature values at various locations in the kiln, he was still a little worried if he didn't see it himself.
After all, it is difficult to control the temperature of a wood kiln. Even if he sets a series of parameters and lets his trusted workers take turns to watch, he will not be completely reassured.
Compared with ancient times, modern kilns have been scientifically calculated, so it is not too tiring.
Even so, Chen Wenzhe will only hand over the care to other workers when the temperature inside the kiln reaches a stable period.
It wasn't until the next day, when the firing was almost done and the temperature started to cool down, that he would come over to check the heat again.
When there was no problem at all, the temperature gradually dropped and the kiln was started.
Fortunately, we are not in ancient times. There are many ways to increase the speed of temperature, control temperature, etc.
Otherwise, it would be very hard to fire the kiln, because in ancient times, it often took several days to open the kiln for firing at a time.
But things are different now. Modern kiln workers all know that it takes about 7-8 hours for ordinary ceramics to be fired at 1300 degrees, and 10-12 hours for high-aluminum porcelain at 1700 degrees.
Develop the temperature curve, degreasing section-heating section-insulation section-cooling section.
From the initial preheating to the subsequent temperature curve, depending on the type of furnace, what kind of porcelain is fired, and the internal atmosphere curve of the kiln, all can be controlled.
Even the shape and size of the porcelain are related to the appearance of the final fired porcelain.
This kind of work, speaking of precision, is quite technical.
To say it's rough is just that.
This is also a job that is not difficult for those who know it, but difficult for those who don’t know how to do it.
If Chen Wenzhe wants to teach, he can learn it easily as long as he studies hard. After all, he just needs to remember some key points.
If he doesn't want to teach, many things will require a long period of exploration and continuous firing of kilns before he can finally sum up the experience and lessons.
This time is not a day or two, nor is it a year or two, or even ten or eight years. Not much experience can be summed up.
Kiln firing is only an important step in making porcelain, and there is nothing to keep secret. As long as someone wants to learn, Chen Wenzhe will teach him.
Of course, it would be more troublesome for local workers in South Vietnam to study.
First of all, their Chinese is not good, and secondly, Chen Wenzhe will definitely not teach them specifically.
After entering the insulation section and feeling that there was no big problem, Chen Wenzhe returned to the dormitory to rest.
After breakfast the next day, as soon as he arrived at the factory, someone told him that more goods had been delivered.
At first, Chen Wenzhe thought they were raw materials for making porcelain. Unexpectedly, when he opened the packaging box, he found various pieces of porcelain.
"Who gave it to me? It shouldn't be Li Jinli!"
Chen Wenzhe looked at various porcelain pieces. He had collected these porcelain pieces before, and Cao Qingchun helped collect a lot of them.
But he didn't ask them to send the collected broken porcelain pieces here!
"Boss, is there a phone number here?" Zhang Gu asked at this time.
"Wu Er's?" Chen Wenzhe took out his phone and called according to the number.
After a while, Chen Wenzhe put down the phone.
It really has something to do with Wu Er, but this batch of porcelain pieces came back from abroad. Wu San should have helped collect and send them over.
The broken porcelain pieces from abroad still made Chen Wenzhe a little interested.
He poured them all out and sorted them carefully. There were red, green, yellow, three-color, five-color, pastel, blue and white, and enamel colors.
The most important thing is that there are fragments from various dynasties and they are very complete, which is very rare.
Recently, he has been mixing a lot of glazes of various colors, and he just needs this kind of thing.
"When did Wu San become so considerate?"
Holding a piece of green glazed porcelain, it felt very beautiful, so Chen Wenzhe already had a smile on his face.
Wu San definitely put his heart into it. Not to mention other things, it is just a green glazed porcelain piece, and there are many kinds here.
After a little selection, he actually picked out more than ten kinds of green glazed porcelain tiles of various colors, which was not easy.
What's even more amazing is that Chen Wenzhe can see that these green glazed porcelain pieces are very beautiful, and they should all belong to official kilns, or they are fine products from private kilns.
Although such porcelain pieces have no text and incomplete patterns and decorations, there are only a few remnants.
However, their role is really valuable to Chen Wenzhe now!
If it were the original, looking back at these broken pieces of porcelain, he wouldn't be able to see much information.
But it's different now. Through these broken pieces of porcelain, he can not only see the production process of the complete vessel, but he can even see some information related to it through these broken pieces of porcelain.
In this way, Chen Wenzhe can learn a lot from the value of these broken porcelain pieces.
Not to mention anything else, just the mixing of glazes on these porcelain tiles is a great reward.
"Wu San has contacted you recently?" Chen Wenzhe asked happily after admiring it carefully for a while and recognizing many classic porcelain fragments.
If possible, he wouldn't mind meeting some of Wu San's requests. After all, they had done him a great favor.
"Not recently. Half a month ago, when the contract was just signed, we contacted him several times!" Zhang Gu said.
He usually takes care of the affairs in the factory, so he has some contact with Wu San, but they haven't talked on the phone for a long time.
"After such a long time? How can I still help collect porcelain fragments? Not many people like this thing."
Holding two or three broken pieces of porcelain, all with green glaze, he had never thought that green-glazed porcelain could be made so beautiful.
"He originally asked about your interests and hobbies, so I told you a few. I didn't expect that he could collect so much in just half a month!" At this time, Zhang Gu said again.
"Ask?" Chen Wenzhe asked curiously.
"Yes, I gave the boss a treasure, so I naturally want to pay attention to your recent activities. Knowing that you are constantly firing Ru kiln porcelain, I thought of giving you a gift to thank you for your hard work."
"I like this gift!" Chen Wenzhe burst into laughter.
Recently I have been making high-end antique porcelain, which is quite hard.
Now is the time. When he takes a break, he can review the broken porcelain pieces and maybe add a few more classic porcelain pieces.
Anyway, I have nothing to do recently, so I just imitate the most exquisite classic porcelain from all ages.
Chen Wenzhe did not put away these porcelain pieces, but placed them one by one outside the workbench.
Backtracking does not necessarily require his constant attention to do it.
As long as he doesn't read the scene that was traced back, but only stores the traced information into the Pearl of Sui Hou, he only needs to put these fragments in front of him.
