I went back to ancient times to do business with my game account

Chapter 239 Overglaze Color

When Dong Erlang heard that someone was firing porcelain, he immediately blew his beard and stared: "What are you doing, you layman?"

Fangzhu Zhao hurriedly dismissed Dong Erlang: "Shut up, this is a distinguished guest!"

Dong Erlang shrank his neck from his reprimand, and stopped speaking.

Fangzhu Zhao then turned his head and showed a kind smile to Qiao Yun: "Guest officer, what do you want that porcelain billet for? It can't be used, and it has to be returned to the furnace for a second time. The current furnace makes this idiot It’s burnt out, let alone useable.”

"I said, show me the porcelain blank."

Qiao Yun's smile didn't fade, but there was already a hint of impatience in her tone.

Fangzhu Zhao hesitated for a moment, thought carefully, and there was nothing wrong with showing her.

He said to the little apprentice in a very rude tone: "Go, take out your burnt things and show them to the guest officer."

The little apprentice wiped away his tears in grievance, ran into the brick house, and took out his burned things.

"Here, this is it."

Qiao Yun took the white porcelain blank, a pair of bright and agile eyes flashed a trace of surprise and joy.

In her previous life, she once traveled to Jingdezhen and visited many kilns in Jingdezhen.

The famous ceramics in Jingdezhen are not only the blue and white porcelain with underglaze color, but also the exquisite porcelain with engraving technology on the porcelain body, the colored glaze porcelain with colorful glaze color like gems, and the representative term of overglaze color, famille rose porcelain.

She has seen many white porcelain blanks like this in the kiln mouth of pastel.

The surface of underglaze color is smooth, does not fade, and is durable to wear, while the pattern drawn by overglaze color will highlight the glaze surface, which feels more hand-feeling, far less smooth than underglaze color.

But the color texture of the overglaze color is far from that of the underglaze color.

Glaze color is actually not suitable for tableware, but she wanted to highlight something special this time.She plans to use overglaze on the outer walls of utensils such as soup pots and bowls, which look brighter, and underglaze for plates and the like.

Most of the porcelain in the Tang Dynasty was underglaze color, and the overglaze color was not invented until the Ming and Qing Dynasties became more mature.

The underglaze color is to quickly bake the kneaded porcelain green embryo at a temperature of about [-] degrees Celsius. After baking, it is decorated with colored paintings, and finally it is fired at a kiln fire of about [-] degrees Celsius to [-] degrees Celsius. glazed.

The overglaze color is to burn the white porcelain blank at a high temperature of about [-] to [-] to produce a beautiful layer of glaze, then to decorate the surface of the porcelain with colored paintings, and finally put it into the kiln with about [-] degrees. The characteristic of kiln firing is that the glaze color and pattern need to be fired separately.

The plain white porcelain blank in Qiao Yun's hand is almost the same as the semi-finished products piled up in the mouths of those overglaze kilns in Jingdezhen in later generations.

If such a porcelain body is taken away and decorated with underglaze paint, and finally fired at high temperature, it will definitely not work.

Seeing her holding the porcelain blank and looking around, Dong Erlang scoffed a little, hum, he thought she was an expert just now!I didn't expect to be dumbfounded holding a waste product!

Fangzhu Zhao was also a little confused, he asked: "Guest officer, what kind of tricks have you seen?"

Qiao Yun raised her head, smiled and handed the porcelain blank back to the little apprentice, and said kindly, "What should I call you?"

Looking at this little lady who was a head lower than himself, the young Xiaolangjun suddenly felt a sense of meeting a bosom friend. He sniffed and said, "My surname is Shi, and I have no name. The master and the master both Call me Stone."

"Oh... Mr. Shi Xiaolang." Qiao Yun nodded thoughtfully, she turned to Fangzhu Zhao and said, "I'll leave this batch of orders to him to burn."

Dong Erlang was so startled that his legs gave way and he almost fell to the ground. He kept yelling, "What, what? This guest officer didn't see what the ball made of porcelain, and let him do it?"

Fangzhu Zhao was also a little surprised, as if he heard a thunderbolt from the blue sky, he asked: "You, are you kidding me?"

Qiao Yun nodded: "I'm in the south of the Yangtze River... Oh, Raozhou, I've seen a kind of porcelain, and that's how they burn the porcelain body."

As she said that, she looked around at the people present, especially Dong Erlang and Shitou, and said firmly: "When you usually burn porcelain, do you first fire the plain body at low temperature, paint decorations, and then go into the kiln and fire it at high temperature?" Is the glaze coming?"

Dong Erlang nodded reflexively: "Isn't it true, isn't all porcelain fired like this?"

Qiao Yun took a breath and said, "Then I'm going to say that this batch of porcelain, such as soup basins, cups, and bowls, needs to be fired at a high temperature to produce a glaze color, and then it is taken out and decorated before being used in the kiln. Burn at a low temperature. The time for the second burn...well...about four hours."

Seeing that Fangzhu Zhao and Dong Erlang were still talking, Qiao Yun jumped ahead of them and said, "The Ding Shiji happens to have tableware from Raozhou. Although there are not many, there is room for them. I will bring one tomorrow." Let the plate come over to let you see what kind of porcelain they fired over there."

Raozhou is located in today's Poyang County.But in the Tang Dynasty, the scope of the entire Raozhou was still very large.

Jingdezhen is in Raozhou.

Of course, Jingdezhen probably didn't exist at this time, and there wasn't any overglaze painting. This was Qiao Yun's nonsense.

In ancient times, transportation was inconvenient, and everything spread extremely slowly.

It is even more difficult for ceramics, a luxury product that breaks when touched, to spread on a large scale. Although there is a Grand Canal, ships on the inland river can't transport much ceramics at a time. Expensive, so ceramics are still spread around the mouth of each kiln.

Four of the five famous kilns in the Northern Song Dynasty were located in Henan, because Bianliang was the capital of the Northern Song Dynasty.

It is even more impossible for the owner of the small porcelain kiln workshop in front of him to immediately go thousands of miles away to seek proof.

Stone was so moved.

Someone recognized his ability!
He just said, this time he slapped his head, and the furnace that was fired out of a whim, although it is all plain white porcelain blanks, and it is true that it cannot be glazed at high temperature, but it doesn't look like something burnt out!
He was a little annoyed, and with a bit of imperceptible resentment, he secretly glanced at Dong Erlang and Fangzhu Zhao.

One of these two people is a porcelain kiln owner and the other is a veteran of porcelain firing, but the result is not as good as this little lady's discerning eyes!
After ordering everything and paying the deposit, the two left the Zhao Family Porcelain Kiln, Wang Jinzhi was still a little worried.

She pulled Qiao Yun and asked worriedly, "Are you sure that person is okay?"

"Don't worry." Qiao Yun said with a smile, "It's his first time firing porcelain, and the white porcelain blanks he fired are so pure and free of impurities, which shows that he has talent, and his control over the kiln fire is not bad."

"Be careful, my birthday party is not far away! If something goes wrong with this batch, what will happen to the party?"

"When the time comes, I'll give you the bottom line." Qiao Yun hugged Wang Jinzhi's arm and acted coquettishly: "At worst, I'll close Ding Shi Ji for a day and use the tableware in the restaurant to hold a banquet for you!"

Holding the limp little loli in her arms, Wang Jinzhi looked at Qiao Yun's confident eyes, her heart softened, and she let go.

"Okay! Then you have moved out of Ding Shi Ji, so I will trust you."

On the second day, Qiao Yun took out a famille rose peony teapot and a famille rose peony tureen from the game, put them into the bag behind the saddle, and asked Yun Xuemei to ride the horse to Zhaoji Porcelain Kiln.

Fangzhu Zhao and Dong Erlang stared straight at this thing.

"This... is this really ceramic?!"

"It's not ceramics!" Qiao Yun was rather annoyed, "I just burn it like this, you understand?"

"How did this come out of the fire!" Dong Erlang looked at the beautiful meticulous painting on the teapot, couldn't put it down, wanted to touch it but dared not.

While the two were marveling at the pottery that Qiao Yun had brought, Shi Shi came out of the brick kiln with a look of hope on his face.

Shi Shi looked haggard, and his eyes were covered with bruises. It seemed that he hadn't slept all night.He took out a small cup from his sleeve and handed it over: "I, I stayed up late last night and tried to burn one, because it was a trial product, and the pattern was a bit missed. You, take a look..."

On the snow-white porcelain cup, only a simple peach blossom branch is drawn, but the texture and color are very similar.

Dong Erlang's eyeballs almost popped out.

This kid, why did he really burn out?

Qiao Yun was ecstatic.

"That's right, just press this to burn!"

Thank goodness!

This little man is simply a genius!
