Pieces

Although Ba Niang didn't understand this, she looked over at the pottery fragments and knew they were extraordinary.

Most of the porcelain pieces produced during the test firing are completely white, with only a small amount having a faint pink color. This is because the impurities have not been removed.

This is a kind of porcelain they have never heard of!

At present, most of the general porcelain, except Jun kiln, which is slightly better, has a dark body color, indicating that the internal texture is crisp and loose, and it mainly relies on glaze color decoration.

As for this porcelain tile, the internal molten vitrification effect is excellent, and the whole body is as white as snow, crystal clear and fine!

Such a matrix is ​​like a piece of white paper. Apply different glazes and you can immediately get various colors of fine porcelain.

Su You was extremely picky, so he woke up the two idiots and started firing the next two furnaces.

Then, together with Shi Da, all the porcelain pieces were appraised.

Even the worst-grade porcelain pieces can easily scratch marks on pottery pots. Such hardness is difficult to match among all existing porcelains, let alone pottery.

Thin as jade, stronger than steel!

The rest is to compete with each other among the porcelain tiles, and then take into account the shrinkage ratio, viscosity, and processing difficulty, and finally determine the formula of the first batch of No. 15 porcelain tiles as the matrix formula.

As for the No. 3 porcelain tile formula of the third furnace, it shows perfect glaze melting at high temperatures and can be used as the basic formula of a new glaze.

Su You smiled at Twenty-Seven Niang and said: "Look, if you select ingredients more accurately, the processing techniques are more delicate, and the experiments are more scientific, the results will be more sophisticated."

Twenty-seven Niang and Shi Da didn't know what science was, but that didn't stop them from nodding their heads.

Su You said: "Twenty-seventh mother, Eighth mother and I have finished our work. For the formula of the printing material, we have chosen No. 12 for the first batch."

Twenty-seventh lady grabbed Su You and said, "Don't let me go! You must burn the porcelain for me!"

Su You said: "These are experimental products now. They are basically no problem in dealing with calligraphy. But porcelain burning does not take a day or two. If the mud is not aged, it will not achieve the best porcelain-making effect. You are experts and you should know it."

These.”

Shi Da was extremely excited and said to Su You: "Young Master, do you mean there is still room for improvement in this porcelain?"

Su You said: "That's right, and there are many areas that can be improved, such as kiln mouth insulation and air intake preheating. These methods can increase the furnace temperature..."

"For example, pickling can purify quartz sand..."

"For example, Guanyin soil removes impurities..."

"For example, the formula will continue to be refined and optimized..."

"For example, using test paper to accurately measure pH..."

"For example, develop a glaze sprayer, take the opposite approach to building a kiln, and make the glaze layer as thin as possible..."

The words made Twenty-seven Niang and Shi Da's eyes bulge.

Su You sighed secretly in his heart. This thing is the only type of porcelain developed by Europe after the great development of the glass industry. Even so, its thickness is not as thin as that of Chinese shadow celadon. Although it can also transmit light,

But because Yingqing is as thin as an eggshell, it can beat it by a few in terms of light transmittance.

Its advantages are that it is hard and fair. Well, if ease of mass production is a benefit, you can also add this.

If there was a crack in the ground, Twenty-Seventh Mother would be eager to get into it now.

Seeing the indifference, regret and slight disapproval on Su You's face, Twenty-Seventh Mother knew that the family's proud ceramics workshop and those excellent porcelain pieces just now were in his mind.

What is the weight in .

It is said that children cannot lie, but because of this, it hurts people even more.

After cleaning up her messy mood, Twenty-Seventh Mother sighed softly, found a box, lined it with fine linen cloth, numbered all the porcelain pieces, and stored them in a precious and important way.

Su You saw Twenty-seventh Mother's disappointed look: "Twenty-seventh Mother, you know what I said is the truth."

Twenty-seven mothers said: "I know. Looking at what you have done in the past two days, I already understand."

Su You couldn't help but paused and comforted: "The Jiang Qing family has always been one. Let's take our time and improve step by step."

Twenty-seven mothers raised their heads in surprise: "Really? Xiaoyou, you promise to help me?"

Su You said innocently: "I never said I wouldn't help you, but things are so complicated that I can't figure out a plan at the moment. I need to think about it carefully. In terms of time, I estimate that the process can be completed within three to five years. In the future,

The exploration is endless.”

"And this is not only related to porcelain making, but also involves many related processing techniques and manufacturing technologies, involving many, many products and industries."

"Where does technology come from? It requires a lot of investment to develop technology and transform equipment. Therefore, we can only accumulate it step by step."

"Use business to gather wealth, use wealth to develop technology, use technology to support industry, use industry to run business, and then maintain technology to replace differences. The soup plate inscription: 'New every day, new every day, new every day.' Only in this way can we remain invincible.

land."

Twenty-seven mothers gave Su You a gentle blessing and said with a smile: "Xiao You is a real man, but if you have orders, no one in the slave family dares to disobey them."

Su You smiled and said: "Then let's eat the braised beef first!"

The braised beef is already flavorful, so let the cook cut it into large slices against the muscle texture. Eat one portion just like this, and mix the other portion with garlic juice, celery, crushed peppercorns, sesame oil and salt to make a cold salad. Add a few seasonal vegetables and you have a complete meal.

The current braised pork in the Song Dynasty is actually more similar to braised pork. Now that the recipe of Su You Thirteen Spices has been developed, it can be used in more places.

This formula of sour oil was given to Baniang, and the future charity work of the dock will also be controlled by Baniang.

After telling Shi Da to start the work of forging clay according to the No. 12 recipe, Ba Niang and Shi Qi Niang took Su You back to the city. They also had to go to the dock to oversee the construction of the charity shed.

Su You rushed to find Cheng Wenying. Great progress had been made in the clay work, and the engraving and color printing work could be improved again.

I ran into the bookshop, and fortunately, there were still two old men left among the three. Old Han went to make color adjustments, while Cheng Wenying and Old Yu were gesticulating and discussing over a ready-made engraving.

Seeing Su You come in, Cheng Wenying greeted warmly: "My dear nephew, the Shi Dai you asked for has been brought. I asked the pharmacy to make a fine powder using a new method. Can you see if it is still suitable for use?"

Su You opened it and took a look. He was very satisfied. He closed the box and said, "Uncle-in-law, on the way back, I thought of another way."

Cheng Wenying's head felt a little tight again. He felt that he was used to a slow life, and it was really difficult to keep up with his nephew's thoughts. He couldn't help but put his hand on his temple and asked: "What does your nephew think?"

Su You said: "The porcelain seal prescription over at Taofang has been successful."

Cheng Wenying said in surprise: "So fast?! Show me quickly!"

Su You then remembered that all the test pieces had been taken away by Twenty-Seventh Mother, and said awkwardly: "Uh, they are all at Twenty-Seventh Mother's place, and I didn't bring them with me."

After saying that, he waved his hand: "But this is not important. What is important is that I thought of a way to speed up the production of color printing plates."

Cheng Wenying asked curiously: "What else can we do, other than carving it slowly?"

Su You said: "Don't we have ready-made engravings? Brush the engravings with beeswax and fill them with gypsum mud to get a mold for the engraving. Then put clay into the mold. After the clay dries, remove the gypsum.

You can get the clay tablets."

"Although it is rougher than the original version, one advantage is that it is convenient and fast. Dig out the required single-color plates, remove the unnecessary parts of each color plate, and then carve and repair them carefully. It is much faster than carving the clay tablets."

"Waiting until the trimming is completed and sending it to the kiln to fire the porcelain plate can save a lot of time."

Cheng Wenying happily slapped his thigh: "Take a photo! This is the reason why the imperial court uses money mothers to make coins!"

Old Yu had long admired Su You and said, "Young Master is truly a child prodigy. I admire him so much."

Cheng Wenying said: "Let's go to Taofang now."

Su You smiled and said: "There is no need to rush this. You continue to finalize the details. First, look through the plaster. The clay needs to be tempered and it will take time. I went to Shajixing to learn rhyme."

Seeing Su You's small figure stepping onto the street, Cheng Wenying withdrew his gaze: "I wish I had another daughter..."

Lao Yu laughed slyly from behind: "Master, hurry up and get another room. In fact, it's still not too late."

Cheng Wenying turned around and said, "Get out! Wait, can you cast this plaster cast?"

Lao Yu said: "Oh! I'm so happy just to patronize you! Please call the young master back quickly."

As soon as Su You sat down, Cheng Wenying grabbed him out.
Chapter completed!
