Chapter 1,042 Its an accident, but its also inevitable
Looking at the azure three-legged bath in front of him, Chen Wenzhe seemed to have seen Yan He back then.
Not to mention anything else, the glaze of the porcelain he produced is beyond the reach of ordinary people.
The glaze is like jade, which must be related to the inclusion of agate in the glaze.
Through review, Chen Wenzhe was able to determine that the glaze color of Ru kiln was so delicate because agate powder was added to the glaze.
However, the glazing of agate seems to have nothing to do with the glaze color and changes in glaze color?
Adding agate to the glaze can make the glaze surface as crystal clear as jade, but it cannot appear azure?
Also, modern research shows, especially the latest laboratory reports, that although agate powder and the main minerals in the glaze are not mutually exclusive, they do not contribute to changing or improving the color.
Of course, this information is a big blow to artists who have lost their ambition to revive Ru kiln, but it is an affirmation of the precious value of Ru kiln in existence.
Because even the only clue that could decipher the secret recipe of Ru Kiln has been broken, this cultural heritage becomes even more rare!
Seeing this, Chen Wenzhe was already laughing and the corners of his mouth were cramping. There was definitely something wrong with this.
The role of agate in glaze is certainly controversial.
Of course, the more difficult it is to make Ru kiln porcelain, the happier he will be, so that he will have a greater sense of accomplishment when he imitates it!
"There are too many pitfalls here!"
Chen Wenzhe found that there were so many things that could be learned.
As long as modern people don't understand it and feel it's a trap, it's worth learning.
Feeling that the harvest would definitely be great, he simply found a comfortable place, half-lying down, squinting his eyes, and completely lost himself in the memories.
"Fire light?" Just now he was watching the firing process of Ru kiln porcelain, so what he saw must be a kiln!
When observing the kiln, a special term must be mentioned: fire!
He has heard of this term. "Tao Ji" written by Jiang Qi of the Southern Song Dynasty is the earliest document that can be traced that records the porcelain making technology of the Song Dynasty.
Information about kilns, porcelain-making raw materials and "fire photos" are all recorded in "Tao Ji".
After checking it carefully, Chen Wenzhe immediately became happy. It was full of useful information!
This time, he did not make the embryo first, but first looked at the kiln and kiln-firing technology of the Song Dynasty.
Fire photos, also called "test pieces", are used to measure the temperature in the kiln.
The Huozhao of the Song Kiln was made from a bowl blank, with a flat upper part and a pointed lower part, roughly in the shape of a 5.
The lower tip is inserted into a sagger filled with sand. The sagger is placed in the kiln chamber and can be seen in the fire viewing hole.
There is a round hole on the upper end of the fire lamp. When the kiln worker measures the temperature in the kiln, a long hook is inserted into the fire observation hole and the fire lamp is hooked out of the sagger.
Every time a kiln is fired, the fire light must be inspected several times. Each time a fire light is inspected, a fire light is drawn.
The fire photos are half-glazed and can only be used once.
When firing porcelain, the fire light socket is placed at the front end of the kiln bed near the kiln door, so that during the firing process, the kiln worker can use a long hook to go deep into the fire observation hole, pass through the small hole in the middle of the fire light, and hook out the test piece for inspection and judgment.
The temperature in the kiln and the color of the glaze.
Chen Wenzhe read and compared the knowledge he accumulated.
He now has a very good understanding of the firing of Ru porcelain and has accumulated a lot.
You must know that imitating Ru porcelain is not that simple, so many ancients have done research in this area.
One of the major categories is embryo making, and pottery carts have to be mentioned when making embryos.
A pottery cart is a ceramic product forming machine, also known as a pottery wheel, pottery wheel, or pottery wheel.
In the Dawenkou Culture of my country's Neolithic Age, pottery shaped using pottery carts has been unearthed.
The pottery cart is composed of wooden plates and frames, and is equipped with bamboo sticks and frames.
The entire pottery cart has basically fallen to the ground. Only the wooden plate is slightly above the ground about 20cm, and the machine is not visible.
The frame is square in shape and is composed of wooden sticks. It is set around the wooden plate and is a certain distance above the wooden plate.
The craftsman sits on the side of the frame, facing the wooden plate, with his legs placed on the wooden sticks on both sides of the frame.
A good spatial state is formed between the craftsman and the pottery cart and its movement. The arm activity area is wide and flexible. Whether using a bamboo stick to rotate the cart or drawing the slab, the arm and finger strength can be maximized. .
Moreover, the two knees can support the two elbows, which can stabilize the arms and prevent irregularities in the body due to shaking of the arms.
Compared with the drawn pottery cart, the drawn pottery cart is located above the ground, the wooden plate is smaller, and the machine frame is visible.
This makes it easier for craftsmen to sit or stand while painting and glazing.
The machine frame should consist of a straight wooden shaft, shaft top cap, swing hoop and wooden pole.
The pottery carts of the Song Dynasty should not be much different from those of later generations, especially those of the Yuan and Ming dynasties.
Chen Wenzhe had never seen the pottery carts of the Song Dynasty, but he knew about the pottery carts of the Ming Dynasty and knew how to use them.
By the Ming Dynasty, Song Yingxing's chapter "Tiangong Kaiwu. Pottery" specifically introduced the production process of ancient porcelain and introduced the tools and equipment for making porcelain.
There is a description of "After testing the soil to find mud, the pottery wheel is still made. Those who are skilled in the skill pinch the clay according to the size of the pot, and do not add much. Two people hold the clay and rotate it, and it is done with just one pinch."
The chapter "Tiangong Kaiwu. Pottery" records in detail the ancient method of using pottery carts to shape.
Of course, this is not because Chen Wenzhe wants to learn how to use ancient pottery carts, but because he saw that Yan He, the author of the Three-legged Washing Machine, was very knowledgeable about pottery carts.
In fact, these are not important. What is important is that after he made this exquisite Ru kiln three-legged washbasin, he actually summed up his experience and wrote a book "An Explanation of the Porcelain Making Atlas".
Chen Wenzhe was sure that he had never heard of this book.
Needless to say, even if this book was published in the Song Dynasty, it must have been lost.
Yan He's craftsmanship has reached its peak in producing fine porcelain from Ruguan Kiln.
It doesn't seem so strange for a master craftsman like him to write books and talk about it.
Besides, the social atmosphere and cultural exchanges in the Song Dynasty were relatively open-minded.
Yan He came from a porcelain-making family, had accumulated enough money, and successfully transformed Ru kiln from a private kiln to an official kiln, so he was naturally qualified to write a book.
Seeing this, Chen Wenzhe naturally became more interested in this book "An Explanation of Porcelain Making Atlas".
Firing a fine piece of Ru porcelain is very important, but the works of a Ru porcelain master seem to be even more important.
Fortunately, Chen Wenzhe's cheating methods have now been upgraded, and there are many historical fragments related to this Ru kiln three-legged wash. Even if this porcelain is not involved, he can still see the full picture.
Therefore, as long as Chen Wenzhe thought about it, he could see this "Porcelain Making Illustrations", and it was the complete book.
Unexpectedly, the beginning of this book records how Ru kiln changed from a private kiln to an official kiln.
This can also be said to be the beginning of Yan He’s family’s glory, so he naturally wanted to record it!
It was also at this time that Chen Wenzhe determined that many of the legends were exaggerated and should not be fully believed.
For example, the previous legend of martyrdom in the kiln was false, because it was not difficult for Yan He to make azure, and he would not be embarrassed!
It can be said that Ru kiln changed from a private kiln to an official kiln, which was an accident but also inevitable!
