A pair of roughly identical bottles, one failed and the other succeeded.
The same temperature and the same kiln firing technology cannot produce such a big change because of the temperature. Then it can only be the red glaze formula.
In this firing, Chen Wenzhe was mainly doing experiments, so the formula used for each piece of porcelain, even the location of the kiln and the method of controlling the temperature, were different.
Now the results have been produced. According to his most ideal plan, which is the firing method of the first kiln, the firing was successful.
The second kiln failed, so I would not be too optimistic about the third kiln.
Sure enough, after opening the kiln entrances one after another and looking at them, one can tell with just a few glances that they all failed.
Not to mention the two pieces that were mixed with red and blue and fired together, he didn't have a suitable formula. Even if he had master-level temperature control technology, it would be useless.
In two of them, the upper and lower dragons were entangled with each other, and the separation was not very clean, so they failed.
The other one is wrapped around the left and right, at the boundary, whether it is blue and white hair color or red glaze hair color, it will not work.
After burning six pieces, it became one piece, which made Chen Wenzhe a little disappointed.
However, if he can successfully bake one piece according to his ideas, he can successfully bake countless pieces according to this method.
Unfortunately, this is not without flaws, that is, if he opens a kiln, he can only bake one piece. Otherwise, his temperature control technology will not be good enough.
"The quantity never increases. No wonder blue and white underglaze and red have been so scarce throughout the ages."
Shaking his head, Chen Wenzhe used his imagination and started to create again.
He believed in evil, so the works he produced this time were all made of blue and red glazes separated.
As long as the blue and white glaze and red glaze are slightly separated, he can fire it successfully.
Since the success rate is guaranteed, Chen Wenzhe does not need to bake all the elephant-leg bottles.
In the past, elephant-leg bottles were made because of their large size and because they were simple to make.
In fact, he had misunderstood. The elephant-legged bottle was forty centimeters high but only fifteen centimeters in diameter. It would be a bit difficult to completely separate two dragons from such a bottle.
Therefore, Chen Wenzhe only made one piece this time, and the others were either made into plates or large pots.
Such two dragons can more easily stretch out their bodies without interfering with each other.
After entering the kiln, Chen Wenzhe carefully controlled the temperature. After passing the warning point and feeling that there would be no problem, he set the next firing temperature and stopped caring about it.
After working for two days in a row, he was still a little tired, but he had gained a lot.
After sorting through the harvest of these two days, Chen Wenzhe knew very well that from the perspective of firing technology, in order to obtain good underglaze red and blue and white colors, each needs to be carried out under a specific firing system.
To fire the two pigments under a unified firing system, you must look for the underglaze red formula and the blue and white formula that are fired under the same system.
The methods used by Chen Wenzhe now are not original to him.
In this world, nothing can be done without taking it seriously. As long as you take it seriously, you can achieve anything.
The method he used was actually thoroughly studied in the 1990s.
In the 1990s, some masters were able to successfully fire blue and white underglaze red porcelain in a wood kiln.
However, it still requires a skilled kiln firing master to master the kiln atmosphere, and mass production is not possible.
Using modern testing methods to fire blue and white underglaze red porcelain with gas was only completed in the 1990s by an expert scientific research team, and could only be produced in small batches.
Compared with wood kiln firing and trial and error firing using testing methods, Chen Wenzhe's success rate is considered high.
However, he can only produce in small batches, so the price of blue and white porcelain with red underglaze will remain high in the future.
After a night's rest, Chen Wenzhe didn't get up until eight o'clock the next day, because at this time, he could open the kiln again.
In fact, what he looks forward to most is the peony vase. Using the blue and white underglaze red technique, he can create a picture of wealthy peonies, which will definitely be very beautiful.
However, limited to technology, Chen Wenzhe was a little clever this time.
Open a gas kiln and reveal two plates.
The blue and white flowers on the outer edge are rich in color, and the peonies hanging from the branches on the inner wall emit a rich red light.
Seeing this result, Chen Wenzhe knew that his idea had come true.
The outside of the plate is covered with blue and white glaze, and the inside uses the technique of crossing the wall branches to get the peony flowers to the inside of the plate. In this way, the green leaves on the outside and the red flowers on the inside are separated, which is suitable for him to control the temperature, so the firing can be successful.
Unfortunately, this is still a trick, not a true blue and white underglaze red.
Firing it once was just to see if it could be fired in large quantities. Now Chen Wenzhe has succeeded.
At least he didn't let all the copper ions evaporate, and he could successfully achieve underglaze red. However, he still needed to explore the formula for firing blue and white and underglaze red at the same time.
Now, according to his firing method, as long as the temperature of the upper and lower parts is controlled, the blue and white glazes and red glazes can be perfectly colored. The most important thing is that this can be fired in large quantities.
Sighing, he opened the second gas kiln, which fired peony plum vases.
He still adopted a clever approach. The two peonies are both diagonally branched peonies, trying to separate the branches, leaves and flowers as much as possible.
The two peonies all tilt in the same direction, which divides a plum vase into four parts. Two sides have opposite peony branches and leaves, and the other two sides have bright red peonies.
This time the firing was successful, and the two plum vases are very beautiful.
The two colors of green and red complement each other, making the peonies look particularly delicate and pleasing to the eye.
Blue and white underglaze red art porcelain, the harmonious unity of elegance and beauty is vividly expressed here.
Especially the peonies on it, with green leaves and red flowers, are graceful and luxurious, and the country is beautiful and fragrant.
“Finally got a pair of satisfactory works!”
I was just happy here and opened the third gas kiln again, but what appeared inside was a large scrapped tank.
The next three times in a row were all scraps.
Two large cans and two large bowls were all scrapped.
"We still need to separate red and blue!"
This time, Chen Wenzhe finally realized the reality.
Without an accurate formula, the red and blue glazes would not be successfully fired at the same place.
"You still have to look for a blue and white underglaze red one. As long as you get the formula, there are no restrictions."
Real blue and white underglaze red hues have wide variability in their hue proportions.
Either thick and light, or realistic and freehand, they all have profound artistic conception and wonderful craftsmanship, which cannot be compared with Chen Wenzhe's current artful works.
Mainly, red and blue cannot be displayed on the same plane, which limits the visual impact caused by the contrast between red and blue.
"It's not as good as the superior, but it's more than the inferior!"
Compared with the real top-notch blue and white underglaze red works, this one of his is far behind.
However, compared with the blue and white underglaze red porcelain he saw on the Internet, Chen Wenzhe laughed.
The red glaze color of those porcelains cannot be compared with the porcelains he made.
