Several classic green glazed porcelains were thoroughly studied by Chen Wenzhe, and it became easier to make them later.
When he first started, Chen Wenzhe couldn't guarantee that he would be able to directly produce top-notch porcelain such as Apple Green Glaze and Lang Kiln Green Glaze.
Therefore, he started from the basics and first imitated a three-color sea-tangled lotus pattern stemmed bowl from the Zhengde period of the Ming Dynasty.
One of the three colors is green glaze, and it is very likely that it will eventually be fired into a melon-skin green color. We will know if it can be fired once.
Next, Chen Wenzhe imitated a plain three-color seawater toad pattern wash from the Zhengde imperial kiln in the Ming Dynasty.
Plain three-color porcelain, in principle, refers to porcelain containing three or more low-temperature glaze colors, but does not contain or contains a very small amount of red color.
Because in traditional Chinese culture, red represents happiness and is a meat color, other colors of colored porcelain that do not contain red are called plain three colors.
The three here means more, and it does not necessarily have to be three colors.
Plain three-color porcelain is influenced by the image of low-temperature lead-glazed pottery since the Western Han Dynasty, and developed from the mixed-glazed porcelain without red color fired by Jing kiln in the early Ming Dynasty.
It was founded in the Chenghua period of the Ming Dynasty. Since then, it has experienced three important development stages: the Zhengde period of the Ming Dynasty, the Jiajing Longqing Wanli period of the Ming Dynasty, and the Kangxi period of the Qing Dynasty.
The plain three-color porcelain of the Zhengde Dynasty has coordinated colors and simple and elegant colors, giving people a soft and pleasing aesthetic feeling.
"feel good!"
After painting and drying for a while, Chen Wenzhe seemed to see two pieces of porcelain that had been successfully fired.
A tall bowl and a brush wash, the shapes of the vessels are very simple and the colors are not very complicated.
Chen Wenzhe has fired too many porcelains like this in his inheritance. Now he just changed some raw materials, hoping to get the best results!
"Imitate another piece of pure green glazed porcelain and make a white ground green colored cloud and dragon pattern plate."
I glanced at the workbench next to me. Most of the utensils that the boy Zhang Gu had made were dishes.
By using these embryos, he doesn't have to draw and make them himself. The most important thing is that he doesn't have to waste time drying them.
This time Chen Wenzhe imitated a Ming Dynasty Hongzhi plate with blue and white edging and green colored clouds and dragon patterns on a white ground.
This blue and white plate is decorated with green clouds and dragon patterns on a white ground. It is 4cm high, 20.8cm in diameter and 13cm in foot diameter.
This one has a curled mouth, a shallow arc belly, and round feet.
The inner and outer walls of the foot are trimmed obliquely with a knife, and the end of the foot is relatively thin.
On the inner wall near the mouth edge and the inner bottom, two blue and white double string lines are painted.
The inner bottom and outer wall are painted with cloud and dragon patterns, and the outline is outlined with black lines and filled with green color.
The outer wall has underglaze molding with entwining lotus patterns and deformed lotus petal patterns.
The lower edge of the mouth is decorated with blue and white string lines and flower patterns. There are 4 blue and white string lines on the outer wall of the circle foot. The inside of the circle foot is covered with blue and white glaze without any markings.
Feeling that there should be no problem, Chen Wenzhe made an embryonic bowl from Zhang Gu and coated it with a layer of malachite green glaze.
He has fired malachite green glaze dishes before, some with success and some with failure, but now he is very confident.
So, this time he copied another famous product.
The decoration and shape of this malachite green glaze bowl are all characteristics of the Ming and Hongzhi periods, and the authentic treasure is in the collection of the Palace Museum.
If this malachite green glaze bowl is to be successfully fired, it must be glazed on a high-temperature biscuit fired body, then returned to the kiln and fired in an oxidizing atmosphere. The glaze firing temperature is approximately 1,200 degrees.
Previously, the firing of this fine malachite green glaze porcelain was too random, making it difficult to successfully fire it in one go.
But things are different now. If Chen Wenzhe wants to increase his success rate, he needs some skills.
Technology is not based on craftsmanship or formula, but on kiln firing technology.
If he hadn't seen the firing process of the broken porcelain piece given by Wu San, Chen Wenzhe would never have expected it.
When Jingzhen fired malachite green glazed porcelain, the glazed body was placed at the root of the chimney behind the kiln, where the temperature was exactly in line with the firing temperature of malachite green glazed porcelain.
Such skills can only be learned through long-term practice and countless firings. By coincidence, the malachite green glazed porcelain placed at the root of the chimney behind the kiln was fired successfully every time.
Such a little trick.
Although the technique is not difficult, it can be said to be a layer of paper, and anyone can pierce it.
However, who would have thought of such a little trick before discovering it by chance?
What's even more coincidental is that kiln transformation, kiln transformation porcelain, is never something you can get if you want it.
You must know that changing the glaze in the kiln is not something that can be done manually, and it is even more difficult to make the world enchanted by the color after it comes out of the kiln.
Therefore, kiln-turned glaze has always been praised for its unparalleled kiln-turned glaze.
The so-called kiln glaze change refers to the unexpected glaze color effect that cannot be controlled by humans due to the glaze formula and other reasons during the firing process of the utensils.
The kiln glaze is unpredictable and unique, so there is also a saying that "the kiln glaze is unparalleled".
The ancient book "Collection of Barnyard History" records: "Porcelain has the same quality, but becomes different; the same color, and then becomes different colors. The combination of water and soil cannot be added by human skill. This is called kiln change."
Kiln glaze change is due to the fact that the kiln contains a variety of color elements. After oxidation or reduction, the porcelain may show unexpected glaze color effects after it comes out of the kiln.
In ancient times, the emergence of kiln glaze was not under human control, but was the result of accidental firing.
The shape of kiln-glazed porcelain is very special, and the glaze color is very beautiful, but the ancients at that time did not have solid scientific theoretical knowledge.
Therefore, we don’t know the real principle of its formation, but we only have a rough understanding that it is due to the changes in the baking process in the kiln.
The ancients didn't have a better name, so they just called it "kiln glaze".
The biggest difference between modern people and ancient people is that they can trace its principles and let people understand why such changes occur.
In other words, through scientific means, we can figure out the reasons for the changes in kiln glaze.
If the reasons for these kiln changes can be clarified, not only can we produce a kind of red kiln fire, but we can also think about green glaze kiln fire.
You must know that the earliest kiln changes have already appeared on some celadon glaze porcelain before the Tang Dynasty.
The Jun kiln glaze of the Song Dynasty in my country is the earliest known kiln-transformed glaze.
The glaze color of these kilns can be dark or light, or red with purple, or purple with blue, which is unpredictable and miraculous.
During the Kangxi period of the Qing Dynasty, Lang kiln red and Lang kiln green and reverse Lang kiln appeared due to kiln changes;
Cowpea red will turn into apple green and apple green due to kiln degeneration.
During the Yongzheng period of the Qing Dynasty, kiln-varnished glazes also appeared, which were very beautiful and dazzling.
However, the original kiln-glazed porcelain was not accepted by the ancients.
Especially the royal aristocrats believe that the occurrence of kiln disaster means unlucky.
Therefore, many beautiful artifacts were directly smashed.
However, with the development and progress of the times, the ancients' knowledge and understanding of kiln glazes gradually deepened, and later ancients became more fond of this unique and charming porcelain glaze color.
Especially during the Kangxi and Qianlong periods of the Qing Dynasty, kiln-varnished glazes were considered auspicious by the royal family, and official kilns even specialized in producing this kind of glaze-colored porcelain.
