After Xiao Zhang got it done, he turned around and looked at Wang Erlong on the other side.

Wang Erlong was not so tired, and there were a few followers around him to help, but some of the key steps were still done by Wang Erlong himself.

For example, glazing, those little followers don't dare to get started.

If you accidentally ruin Wang Erlong's work, I'm afraid it won't be easy to explain.

Moreover, Wang Erlong is also a craftsman after all, and some steps that reflect the professionalism of a craftsman cannot be handed over to others.

Wang Erlong's glaze looks decent from the color.

Everyone's glaze looks the same, but it's also completely different.

For example, Wang Erlong's glaze, even if it is not configured by Hua Xiangxiang himself, I am afraid that it is also perfectly copied by Wang Erlong.

In this way, we can ensure that Wang Erlong's glaze is fired close to perfect.

Of course, it is not 100% perfect, only Xiao Zhang can be 100% perfect......

Xiao Zhang agreed with his idea.

Wang Erlong's speed was very fast, maybe because he had more plain tires, or maybe because Xiao Zhang had already finished it, so it took Wang Erlong more than 20 minutes to put all the more than 30 plain tires in.

"Okay, please close the kiln!" Director Hu has naturally been paying attention to the dynamics on both sides.

Seeing that the two of them were all ready, they began to close the kiln.

Xiao Zhang nodded, and finally picked up a few pieces of mud that had been fired in advance, stained with a layer of glaze and put it in the kiln, which is how to take it out at any time to check the glaze color during the firing process.

After everything was ready, Xiao Zhang closed the big iron door.

Ignition, temperature control, and so on are done sequentially.

This second firing and the first firing are completely different things.

The time process of firing the kiln lasts for a day and night, and the temperature is controlled at about 1300 degrees Celsius, so that it reaches the level of porcelain.

The fire of the second firing is completely different from the first prime-fired fire, which is made of redox fire, not the true fire of Samadhi, and it is not the fire of the heart of the earth!

From this, it can be seen that the redox fire is even more powerful.

The fire used in azure glazed Ru porcelain and pink green glaze bean green glaze is not the same.

Azure glazed Ru porcelain is fired under heavy redox neutralization and high temperature conditions.

The pink green Ru porcelain is fired in a medium atmosphere and a slightly lower temperature condition, and the bean green Ru porcelain is fired in a light reducing atmosphere and low temperature conditions.

So even so, the firing of each glaze color is completely different.

Now Xiao Zhang can burn the azure glaze.

Not to mention pink green glaze, bean green glaze, moon white glaze, even sky blue glaze, Xiao Zhang is very difficult.

And for the next day and night, Xiao Zhang couldn't leave here.

It is necessary to observe the glaze color change in the kiln mouth at all times, so that the best Ru porcelain can be fired.

Because from now until the kiln is the most critical time.

In ancient times, the traditional Ru porcelain firing process had four major characteristics, and the craftsmen called it the four unique production skills.

These four must be the ingredients, the discoloration, the cracks, and the light.

And these four uniques are the perfect embodiment of the reason why Ru porcelain can be called the first of the five famous kilns.

First of all, the ingredients are absolute, Ru porcelain from the tire material to the glaze selection is very rigorous, must be a certain range of local kaolin, agate stone, gold clay, black soil and other raw materials.

Fortunately, Xiao Zhang's raw materials are all provided by Master Tang Qingchuan, and Tang Qingchuan, as one of the top masters in the capital, has absolutely the best raw materials, and it can almost be said that they are all obtained locally in the place of origin.

Therefore, what Xiao Zhang did before was only the first step of the four uniques, and now firing is only the second step.

The second is the discoloration.

The so-called discoloration is that Ru porcelain adopts a unique stacking firing technique of supporting nails.

It is a unique technique in the firing process of Ruzhou porcelain, and it is also the core feature of Ruzhou Ru porcelain firing technology. This skill is based on the observation and understanding of the kiln technician, and there is no specific and unified quantitative index.

Therefore, the temperature is not constant all the time, Xiao Zhang needs to watch here all the time, watch the glaze color change at any time and adjust the temperature, so as to change the glaze color.

As Hua Xiangxiang said before, what is so powerful about Xiao Zhang, a person who has just started for two and a half days?

Every good craftsman can make a lot of tempering to become a hand.

It is not a strong skill that is possessed, but the experience accumulated over time, and the observation and understanding of the burner are the most important.

This third must be the crack absolutely, the glaze of the general porcelain is a straight crack, and the glaze of Ru porcelain is obliquely cracked, like a fly wing, cicada wing, it is the craftsman through the precise control of the temperature, to get the crab claw pattern, pear skin pattern, caviar pattern, ice crack open piece of fine Ru porcelain.

This fragment will not be seen until after the kiln is opened, so Xiao Zhang is also looking forward to it.

Or what kind of crack direction can appear after opening the kiln by yourself?

You know, whether the crack is beautiful or not determines whether the porcelain is successful or not!

If there are too many cracks, or too few cracks, they are considered flaws, and even the smallest flaws determine whether this Ru porcelain is a fine product.

This last must be the end of the light.

This is also the most magical point of Ru porcelain.

Ying Guangjue is the use of traditional Ru porcelain firing technology fired Ru porcelain products will show different colors and shades with the intensity of light, the difference in sunny and cloudy days, the color will show obvious differences, and the small bubbles accumulated under the glaze will present the wonder of the stars under the microscope.

Such a scene is completely unimaginable for Xiao Zhang.

What kind of porcelain can reveal different colors and tones in different weathers?

This is why there is such a poem that has been passed down through the ages to describe Ru porcelain.

After the rain, the sky is clear and the clouds break the beginning......

This is probably because of the characteristics of Ying Guangjue.

However, this step will not be seen until after the kiln is opened.

Wang Erlong on the other side also got the kiln mouth.

"You have closed the kiln now, everyone can disperse if you are fine, and tomorrow afternoon friends who want to know the results can come and visit again, and now it's late, let's go home and eat." Director Hu shouted to the people around him.

This is also normal, I saw Xiao Zhang and Wang Erlong close the kiln with my own hands, and it is impossible to spend the rest of my boring time with them for this day and night.

So it's just right to wait for the kiln to open tomorrow.

And the people scattered.

Liu Chengfeng walked over and smiled at Xiao Zhang and said, "Stinky boy, you have to come on, I'll wait to see the excitement, don't let me down." ”
