As Master Liu chatted and waited for the kiln to open, Xiao Zhang finally achieved his wish.

Simple rubbing a kiln.

Of course, after Director Hu's signature, the workers began to step forward and turn the handle on the kiln door.

This large kiln is the kind of steel door, and the handles are similar to the swivel wheel handles of the kitchen cold storage, which has better sealing air pressure.

It didn't take long, and when the kiln door was completely opened, Xiao Zhang found that He Xiyu was back again.

And this time, he also brought a few workers, also pushing a large shelf truck.

The car was full of Tang Sancai's plain tires.

Tang Sancai's raw materials are completely different from Ru porcelain, although Xiao Zhang has never made Tang Sancai himself, but he recognized it at a glance.

This plain tire is made of finely processed kaolin as the green body, and the mined kaolin is selected, pounded, washed, precipitated, dried, and then made into a tire with a mold and fired in the kiln.

Tang Sancai's firing adopts the secondary firing method.

From the point of view of raw materials, its carcass is made of white kaolin, after about 1000 degrees of plain firing in the kiln, the roasted plain tire is cooled, and then applied with a variety of prepared glazes into the kiln glaze firing, and the firing temperature is about 800 degrees.

This is the general process of all the firing of Tang Sancai.

Thinking of this, Xiao Zhang was suddenly stunned, it's over......

I'm busy in vain.

This firing of Tang Sancai is different from firing Ru porcelain, even the temperature required for firing plain tires is different.

Firing Ru porcelain, the temperature of the plain tire is about 800 degrees, and Tang Sancai is about 1000 degrees, which is a full difference of 200 degrees, because the carcass material of the two kinds of porcelain is different, so the different temperature difference will definitely lead to the carcass problem......!

Moreover, the glazed Tang Sancai is a low-temperature firing porcelain, and the temperature needs to be controlled at about 800 degrees, and the temperature of Ru porcelain directly rises to about 1300 degrees after glazing, so Ru porcelain and Tang Sancai are not the same thing at all.

This is also a problem that I found only when I recalled the firing process of Tang Sancai.

"Master Liu, I'm really sorry, I'm afraid I can't rub your kiln. Xiao Zhang sighed and said with a smile.

"Well, why?" said Master Liu, touching his big belly and smiling.

"Master, you are a master, this firing Tang Sancai uses a low-temperature firing method, the temperature of the plain firing is about 1000 degrees, and the plain firing of my Ru kiln only needs 800 degrees, the difference is a bit big, I forgot about it at this time. Xiao Zhang said awkwardly.

I only remembered that Su Yuli also came to rub my own kiln, but I forgot that Su Yuli also fired Ru porcelain, which happened to be the same as himself, and this Master Liu was completely different.

Xiao Zhang was a little remorseful...... I knew that I should have helped that Master Hua and let Master Hua use this kiln, after all, the plain tires installed on Master Hua's car are all plain tires of Ru porcelain.

Thinking of this, Xiao Zhang suddenly found that there seemed to be many masters in this palace who fired Ru porcelain.

For example, his teacher Tang Qingchuan, such as Su Yuli's grandfather, the old man of one meter and six meters, and the honorary vice president Master Hua Xiangxiang.

And even if they are all within the system, they have to compare with each other.

Xiao Zhang is also helpless.

"You kid, the old man is still waiting to see your joke, I didn't expect to be reacted by you, I still wonder, your Tang Sancai's attainments shouldn't be unexpected, it turns out that you are really confused, hahaha......" Liu Chengfeng laughed.

Xiao Zhang was completely speechless.

This Liu Chengfeng, knowing that he couldn't rub his kiln with a porcelain plain tire, didn't explain it, and said it bluntly and waited to see him lively?

Isn't this just a righteous revenge!

No way......

Xiao Zhang had no choice but to arch his hand and apologize.

Yes, this time all the kilns in the courtyard were used, and I really had no choice but to go back and wait.

"Master Liu, Xiao Zhang retires, you are well. Xiao Zhang said.

"Go ahead, come and play with me next time, I like you stinky boy very much. Master Liu also said with a smile.

Xiao Zhang nodded and walked to He Xiyu's side again.

The face of this ascetic goddess returned to normal at this time, and her eyes were as cold as ever.

Xiao Zhang smiled, and suddenly said in a very small voice: "Go back and wash your face?" Xiao Zhang finished speaking and walked away quickly.

He Xiyu listened to Xiao Zhang's words, his expression changed, his eyebrows furrowed, but he couldn't help his movements, but his face turned red again......

Xiao Zhang laughed and touched his hair.

He Xiyu saw it in his eyes.

He reached out and touched the hair next to his cheek...... A few drops of water stand on it......

Damn, that bastard found out......

Xiao Zhang thought it was very interesting, this He Xiyu was obviously blushing before, and went back to wash his face and lower his body temperature......

I don't want to wipe it off, and the water droplets are still on the hair.

......

After teasing He Xiyu and Xiao Zhang, he walked boredly on the way back alone.

Xiao Zhang pondered carefully, he had never met any girls in the two years since he came to the Forbidden City, and today he actually met two girls.

One is the granddaughter of the Su family, one meter and five Su Yuli, and the other is He Xiyu, a disciple of Master Liu.

This Su Yuli is obviously active and very lively, although she is petite, her face is cute and a little sexy, but the more active she is, the more Xiao Zhang retreats!

Looking at He Xiyu, at a glance, it is the feeling that no one should enter, and he doesn't like to talk, his face is full of cold frost, his eyes are full of black light, but Xiao Zhang loves to tease this cold?

Xiao Zhang pondered carefully, could it be that he was sick?

......

After walking briskly for a while, Xiao Zhang returned to Tang Qingchuan's studio.

Pushing open the door, it shows a scent.

"What's going on?" Xiao Zhang was stunned.

Inside, Xiao Zhang unexpectedly found that Su Yuli was inside, and the table had been cleaned up, and a lot of food had been placed.

"Brother Xiao, why did you go, I have prepared this lunch, and you have disappeared?" asked Su Yuli with a smile.

Frankly speaking, Su Yuli is still very likable.

This appearance has a strong desire for protection for men......

It's in this feeling that the little bird is human.

And Su Yuli didn't show any ideas, just a simple personality with a good personality and cheerfulness, why didn't Xiao Zhang know how to go up!

"Haha...... Sorry, I'm going to ...... Me too...... I went to the kiln. Xiao Zhang picked up the box in his hand and said.

"Then why did you get it back?" Su Yuli cocked Erlang's legs, and the pink large sweater was also propped up, and it couldn't cover the two white, tender, thin and short dry legs at all......

"This ...... Didn't rub on the ......" Xiao Zhang was a little embarrassed.

"Hahaha, you think it's so easy to rub the kiln, I stayed there for more than an hour before I met you, it doesn't matter if you don't rub the kiln, come and rub the rice, I've already booked it, in order to thank you for letting me rub the kiln, I invite you to dinner!" Su Yuli said with a smile.
