Datang: Acting as a celestial mystery at the beginning

After the play was sent to the cave for firing, Cheng Yaojin didn't know why, and felt that the husband might not be reliable this time.

Put a piece of maple leaf on top of the porcelain body and fire it. Even if something is fired, it is just a piece of porcelain. As for the maple leaf placed inside, it has no effect. The temperature in the cave is so high that it will be wiped out as soon as it is fired.

Sure enough, when the thing came out of the kiln, the leaves were only ashes, and then left faint marks on the surface.

However, the black glazed porcelain bowl looks quite beautiful. The porcelain of the Tang Dynasty is mainly celadon white porcelain, which is as clean as jade, but this is the first time Cheng Yaojin has seen such a black and shiny porcelain bowl. It looks very fresh.

"Sir, this porcelain bowl of yours is very beautiful. If you sell it, you may make a lot of money at first, but if you put leaves in it, it will cause blemishes on the surface, which is very worthless."

Cheng Yaojin hesitated for a while, but still said what he thought in his heart: "Even if there are no flaws, this thing can't reach the level of earning a lot of money that you said, sir."

"General Cheng, this is just a failure, but you can take a longer view."

What Li Yi'an made was not ordinary porcelain, but the famous Konoha Tianmu Zhan in later generations.

Turning leaves into cups, turning wood into gold.

This thing first appeared in the Jizhou kiln in the Southern Song Dynasty. The wooden leaves were placed on the body of the Tianmu glaze, fired at high temperature, and then the leaves were oxidized at high temperature to naturally ash, and fused with the Tianmu glaze to form a texture of wooden leaves.

It is said that only the soil in Jizhou is easy to succeed for this thing, and Li Yi'an asked Cheng Yaojin to send people to dig the soil in Jizhou. The first one that was fired now ended in failure as expected.

"Is this still a failure?"

Cheng Yaojin asked in surprise: "What will the finished product be like?"

"I haven't seen the finished product either."

Li Yian said casually.

In later generations, he only saw pictures of Tianmu lamps, but never saw the real thing.

Cheng Yaojin felt that it was really going to be over this time, and the husband was definitely a failure. It was a pity that he still invested so much money and was going to make a big fortune. From this point of view, everything was ruined.

But he can't do anything. If he dares to ask his husband for money, Li Shimin promises not to kill him.

"Forget it, I'll just play with you, sir."

Cheng Yaojin said proudly: "Sir, how many more do you want to burn, just go ahead, I still have some money for my old Cheng."

"General Cheng, I said you are too small!"

Li Yi'an didn't seem to care about his doubts, and waved a few craftsmen over, saying: "Continue to work."

Li Yi'an taught how to do the method, all of them were members of the Cheng family, so he didn't worry, he quickly made more than ten more, put them all in the cave for firing, and took them out at night, without exception, they failed again .

Successive failures made Li Yi'an lose his temper, but he didn't give up and continued to fight the next morning.

Cheng Yaojin ran over early in the morning, today he said that he didn't want to do it himself, and just threw Cheng Chumo over to help.

Cheng Chumo was even more clumsy than Qi Cheng Yaojin, and after a while, his face was covered with mud.

Then they fired many more batches, all of which failed. Fortunately, there was enough soil in Jizhou, and Cheng Yaojin also had plenty of money. Li Yian did not believe that the last one could not be produced.

Two days passed quickly, the imperial examinations were over, and Li Yi'an's Konoha Tianmu lamp hadn't succeeded, not even a single one.

Every day he had to throw money into it, and Cheng Yaojin couldn't tell how painful it was.

On the third night, Cheng Yaojin finally couldn't bear it and said, "Sir, why don't you forget about it? Don't make any leaves. I think the black porcelain bowl is also very beautiful, and it will definitely sell for money. "

Anyway, they can’t succeed. They only sell these porcelain bowls with Tianmu glaze, and they should be able to pay back the cost. Recently, their production technology has become more and more mature, and the color of Tianmu glaze is getting better and better. You can even see some special ones. pattern.

If things continue like this, let alone helping the poor, Cheng Yaojin feels that he will become a poor household.

Li Yi'an felt that his self-confidence was severely frustrated. Just as he was considering whether to give up, Cheng Chumo ran over and said excitedly: "Sir, do you think this is a success?"

Li Yi'an quickly picked it up and took a look, only to see a red maple leaf with veins clearly imprinted on the bottom of the bowl, it was completely natural, and when he touched it with his hand, there was no flaw.

"Finally...successful!"

Hearing this, Cheng Yaojin snatched it over and took a look, and looked at the porcelain bowl in disbelief.

How could the leaves be fused into the bowl, and they couldn't be picked off without any flaws, which is too beautiful.

"So this is the effect you wanted, sir!" Cheng Yaojin said in surprise.

He is also a member of the aristocratic family, of course he knows how valuable porcelain is, such a Tianmu lamp is so novel and exquisite that there is no second one in the entire Tang Dynasty, and it is definitely a high-quality product.

The husband said that he can make a lot of money, and it is true. This thing can definitely sell for a good price.

"General Cheng, don't be surprised now, Chu Mo, bring some water here." Li Yi'an said.

Pour the fresh water into the Tianmu cup, and Cheng Yaojin and his son were amazed.

The leaves that were originally at the bottom of the bowl, through refraction, seemed to be floating on the water surface, clearly visible, and the leaves rippled slightly with the fluctuations of the water surface.

"This……"

Cheng Yaojin shook his hand and almost dropped the finished product he had made so hard. He said excitedly, "Sir, is this a miracle you created?"

If it wasn't for a miracle, he couldn't imagine why the leaves could still appear on the water.

Cheng Chumo stretched out his hand and lightly touched the water surface, shook his head and said, "It's not a miracle, it's the principle of light refraction, but you don't understand it."

Cheng Yaojin almost slapped him in the face: "Stinky boy, you have studied with Mr. for several months, and you dare to look down on me, right?"

"Okay, General Cheng, you have to teach your son, let's talk about it when we go back."

Li Yi'an interrupted them and said, "If General Cheng sells this Konoha Tianmu lamp in the East Market, how much will it sell for?"

Cheng Yaojin thought for a while, clapped his hands and said: "One hundred guan, we fired it for several days, I lost so much money in it, only one succeeded, I won't sell less than [-] guan! "

Li Yi'an smiled and said, "Won't we make a lot of money in this way?"

"That's right!"

Cheng Yaojin's eyes lit up, one would cost a hundred pennies, and dozens of coins would come out at that time, one could imagine a mountain of coins, he seemed to have selective amnesia, he directly forgot the doubts about Li Yi'an just now, and patted Li Yi'an's With a smile on his shoulders, he said, "I've just said it, the master's methods are superb. If you agree to make a lot of money, you will definitely make it. My old Cheng absolutely trusts you."

"I don't know who questioned Mr. just now."

Cheng Chumo tried his best to expose his faults every day.

"Stinky boy, your skin is itchy, right?"

Cheng Yaojin couldn't take it anymore, he picked up the wooden stick next to him and wanted to beat his son.

Their father and son really escaped too much, Li Yi'an felt that it was not easy for Cheng Chumo to live to this day.
