The process of firing glass is first of all, material selection.
The main raw material for burning glazed products is crucible soil.
The crucible soil mined outside Chang'an City is selected.
The standard for material selection is to use crucible soil with less iron, so that the embryos burned in this way will turn white.
Embryos burned with iron content in the pile soil will turn red, affecting the brightness of the glaze color.
The second step is to dry it.
After selecting the materials, pull the raw materials back to the kiln for drying the materials, because the mined raw materials contain moisture and the dry materials are easily crushed and crushed.
All the crucible soil that Zhao Chen and the others carried back that day were sunburned.
Otherwise, such a heavy crucible soil would not be able to be brought back by human power.
Then there are a series of steps such as ingredients, crushing, and silt.
The water in the pit is soaked with crucible soil, which is called Yin mud.
After the last step of stirring the mud is completed, the pre-task of burning glass is completed.
The process of firing glazing is more complicated than the process of firing cement.
But if it really starts to burn, it will be very fast.
That's like now.
"You go and get all the molds prepared in the yard."
"That biggest one, you have to be careful. If it is broken, someone will cause trouble for you." Zhao Chen said to everyone.
The students of the academy were already impatient.
Immediately rushed to the rear yard.
A few people left behind the kiln fire that had already burned the kiln.
"Sir, I heard that this glass is a Western object, extremely precious."
"I have never heard of it, we can also burn it."
"Your skills are really admired by Qinghe!" Su I, Qinghe, came over and bowed to Zhao Chen.
Su Wo Qinghe was actually suspicious in her heart.
After all, she had never seen this burning glass before, and she felt that no matter how capable Zhao Chen had, he should not be able to do such a thing.
Glazing is originally a Western thing.
How could the East burn such a rare thing?
However, no matter how questioned it is, Su I-Qinghe would not be like others, so she stood up and sang the opposite tune at that time.
This is stupid.
She came to learn from Zhao Chen, not to be right with Zhao Chen.
Su I, Qinghe, is very sure of this.
Zhao Chen looked at Su Woqinghe.
He actually had a good impression of this Japanese princess.
But she was the identity of a Japanese princess, which naturally made Zhao Chen feel irritated.
"This is not a skill, it's just that you are ignorant!" Zhao Chen's words were not at all affection for Su I-Qinghe.
Su Wo Qinghe was talking about it at that time, his face looked embarrassed.
Wu Zi is also a bit strange.
Zhao Chen is very good to everyone, except for the enemy.
But he is obviously not familiar with Su Wo Qinghe, and Su Wo Qinghe is quite good to Zhao Chen.
Why is this guy so unaware of Su Wo Qinghe?
Could it be that the plank road is built openly and the Chencang secretly?
On the surface, I said coldly to Su Wo Qinghe, but behind my back it was...
Wu Yu thought to himself, but he didn't dare to relax at all.
"Others say that beating is a kiss, scolding is love, Bao, are you talking to Sister Qinghe?..."
"Why do you have it everywhere? If you make a noise, you will throw you into the kiln and burn it or not."
"After all, I really love you!" Zhao Chen heard the word "bao" now, even his brain hurt.
Immediately threatened Wu Zi fiercely.
Wu Xi showed timidity on his face.
Li Ruoshuang is not here, so she dare not really fight against Zhao Chen.
Otherwise, maybe they would throw it into the kiln and burn it for Zhao Chen.
This is a loss!
The three of them had their own thoughts and didn't speak.
Cheng Chumo and others came back soon.
One person was holding several burned models.
Li Ke and Qin Huaiyu are different.
The two of them carried a model that was as tall as theirs and moved over step by step.
"I'm so kind, sir, why did you make your Majesty's image?" Fang Yi looked at the model being carried into the middle, smacked his tongue, and looked shocked.
They entered the yard and saw this huge model at a glance.
Other models have larger legs, while those with smaller legs are the size of fists.
But this model is really outrageous.
This is clearly the emperor standing in front of them!
If you are not sure this is really a model, no one dares to move it.
"Sir, are you going to burn your father's emperor out?" Li Ke gasped and asked Zhao Chen.
"Ah, you kid are so good at speaking!" Zhao Chen nodded.
He understood why Li Ke was not liked by the emperor like Li Chengqian and Li Tai.
Can you like this?
Burn an emperor out?
Although they were going to do this, they always felt strange except for saying this.
If the emperor hears it, then he shouldn't kick him?
"Hehe!" Li Ke did not feel ashamed, but was proud and opened the model's cover.
That's right, it's the emperor's celestial spirit cap.
"Sir, did you pour that mud into it from here?" Li Ke asked.
Everyone was thrusting.
Fang Yizhi also ran to the door to take a look.
I was afraid that the emperor would suddenly appear here.
"Yes, put mud in." Zhao Chen nodded.
Li Ke's actions made him feel a little nervous.
If the emperor saw him lifting the inspiration for the model, he would not have to clean up them all.
After firing, the mold must be processed as soon as possible.
Otherwise, there is really no explanation.
"You can all choose a model you like. After firing it, it will be yourselves!" Zhao Chen said again.
Fortunately, these models were created by him by the craftsmen of the Ministry of Works.
They are all in a proper manner.
Otherwise, if these guys from the academy came to do it, they wouldn't know what strange things they would have to make out.
"Mr. Zhao, can I choose one too?" Su Wo Qinghe was very interested.
She found that Zhao Chen had great confidence in making glass.
Su Wo Qinghe began to have some self-doubt.
But Zhao Chen said that he could choose a model he liked, and she couldn't help it.
"All students in the academy are OK!" Zhao Chen said lightly without looking back.
When Su Wu Qinghe heard Zhao Chen say this, he was full of happiness.
Walk quickly into the crowd of models.
I picked a rabbit model.
Wu Xi was different. He held the model of the dragon in front and sneaked aside.
"What are you doing with this?" Zhao Chen even thought, this little girl movie wouldn't be thinking about those false things, right?
"It's made for you." Wu Yu poured mud into the model without raising his head.
"This is Long, please give it to me, I'm afraid I don't want to frame me!" Zhao Chen was very suspicious. This guy wanted to take revenge on the incident he scolded her just now.
Little girl movies are not very old, and her mind is very vicious.
"Do you think everyone is like you and can't suffer any loss?"
"What's wrong with the dragon? You even dare to beat the emperor. It's just a dragon, what are you afraid of!" Wu Xi looked at Zhao Chen with contempt.
But the movements in the hand are constantly.
Zhao Chen felt embarrassed because he was actually despised by a little girl.
"Listen, the fire in the kiln cannot be stopped for two days. Also, no matter what happens, don't turn on the kiln."
"Remember it?" Zhao Chen shouted to everyone.
"Remember!" Everyone responded, but they were busy filling the model with soil, and didn't even look at Zhao Chen.
Chapter completed!
