Chapter 23 Porcelain Tiles

Although Banniang didn't understand this, she turned her head to look at the pottery shards, and she also knew that it was an extraordinary product.

Most of the porcelain tiles that came out of the test were white all over, with only a small amount of faint pink, which was the relationship between the impurities and the inexhaustible impurities.

It's a porcelain they've never heard of!

At present, the general porcelain, except for the Jun kiln, is slightly better, and most of the rest are gray and dark, indicating that the internal texture is crisp and loose, and it mainly relies on glaze decoration to win.

And this porcelain piece, the internal molten vitrification effect is excellent, the whole body is as white as snow, crystal fine!

Such a carcass is like a blank piece of paper, and when different glazes are applied, a variety of fine porcelain colors can be obtained immediately.

Su You was extremely picky, woke up the fool-like two, and then fired the two furnaces behind.

Then together with Shi Da, all the porcelain tiles were identified.

Even the worst porcelain pieces can easily mark on the clay pot, such a hardness, let alone pottery, even in all the existing porcelain, it is difficult to achieve.

As fine as jade, strong as steel!

The rest is to compete with each other among the porcelain tiles, and then consider the shrinkage ratio, viscosity, and processing difficulty, and finally determine the formula of the first furnace No. 15 porcelain tiles as the carcass formula.

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

Su You smiled at Twenty-Seven Niang: "Look, the selection of ingredients is more accurate, the processing techniques are more delicate, and the experiment is more scientific, and 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 like garlic.

Su You said: "Twenty-seven Niang, the matter between me and Ba Niang is completed, the formula of the printing material, we select the first furnace No. 12." ”

Twenty-seven Niang grabbed Su You: "Don't let go!" You have to burn the porcelain for me! ”

Su You said: "Now these are experimental products, there is basically no problem with the word print, but it is not a day or two of hard work to burn porcelain, and the mud is not aged, and the best porcelain-making effect cannot be achieved. ”

Shi Da excitedly said to Su You: "Little young master, that is, there is still room for improvement in this porcelain?" ”

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

"For example, pickling, quartz sand can be purified......"

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

"For example, the formula continues to be refined and tuned......"

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

"For example, the research and development of glaze sprayers, take the opposite path to building a kiln, and make the glaze layer as thin as possible......"

With a few words, the eyes of Twenty-Seven Niang and Shi Da went straight to the circle.

Su You sighed secretly in his heart, this thing is the only porcelain species developed by Europe after the great development of the glass industry, even so, its thinness can not reach the level of Chinese shadow celadon, although it can also transmit light, but because the shadow blue is as thin as an eggshell, so in terms of light transmittance, it can throw out a few streets.

The good thing about it is that it's hard, fair, uh, and if it's easy to mass-produce it, you can add that.

If there is a crack in the ground, Twenty-Seven Niang must be eager to get into it now.

Looking at Su You's indifference, regret, and a hint of disapproving expression, Twenty-Seven Niang knew what the weight of the family's proud ceramic workshop and those excellent porcelain pieces just now was in his mind.

It is said that children do not deceive, but because of this, it makes people hurt even more.

Cleaning up the mess, Twenty-Seven Niang sighed lightly, found a box, put it on fine linen, numbered all the porcelain pieces, and stored them in a precious and heavy place.

Su You saw the lost look of Twenty-Seven Niang: "Twenty-seven Niang, you know that what I said is the truth. ”

Twenty-seven Niang said: "I know, looking at what you have done in the past two days, I have understood. ”

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

Twenty-seven Niang looked up in surprise: "Really? Xiaoyou, you promised to help me? ”

Su You said innocently: "I didn't say I wouldn't help you, but things are complicated, and I can't figure out a charter for a while, so I need to think about it." Time, it is estimated that the process can be formed within three or five years, and the exploration in the future will be endless. ”

"And this is not only about porcelain-making, but also involves a lot of related processing technology, manufacturing technology, and a lot of products and industries."

"How did the technology come about? It takes a lot of money to invest in R&D technology and equipment modifications. Therefore, we can only accumulate slowly, step by step. ”

"Gather wealth with business, become technology with finance, support production with technology, operate business with production, and then maintain the technology generation gap. Tang Pan Ming: 'Gou is new, every day is new, and every day is new. Only in this way can we be invincible. ”

Twenty-seven Niang lightly blessed Su You, and grinned: "Xiao You is really a big husband, but if you have a life, the slave family will not dare to disobey." ”

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

The braised beef has already tasted, let the cook cut it thinly into large slices against the muscle texture, one is eaten like this, one is mixed with garlic juice, celery, chopped peppercorns, sesame oil and salt, and a few seasonal vegetables are added, which is a meal.

The current braised meat of the Great Song Dynasty is actually more similar to yellow stewed meat, and now that the Suyou thirteen-spice recipe has been made, there are more places where it can be used.

This recipe Su oil was handed over to Banniang, and the future dock charity was also mastered by Banniang.

After explaining that Shi Da started the work of forging mud according to the No. 12 formula, Banniang and Twenty-seventh Niang returned to the city with Su You, and the two of them had to go to the dock to take care of the construction of the shed.

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

Ran into the bookstore, fortunately, there were still two old men left, Lao Han went to do color matching, Cheng Wenying and Lao Yu were discussing with each other on a ready-made engraving.

Seeing Su You coming in, Cheng Wenying greeted warmly: "Virtuous nephew, the Shi Dai you want has already been brought, I will ask the pharmacy to use the new method to make fine powder, can you see if it is still suitable?" ”

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

Cheng Wenying's head was a little tight, feeling that he was used to living a slow life, and it was really difficult to keep up with this virtuous nephew's train of thought, so he couldn't help but press his hand to his temples and asked, "What does the virtuous nephew think?" ”

Su You said: "The porcelain printing recipe over there in the pottery workshop has been successful. ”

Cheng Wenying was pleasantly surprised: "So fast?!" Hurry up and show me! ”

Su You then remembered that all the test pieces were taken away by Twenty-Seven Niang, and said embarrassedly: "Well, they are all with Twenty-Seven Niang, and I didn't bring them." ”

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

Cheng Wen said curiously: "What else can be done, isn't it just carving slowly?" ”

Su You said: "Don't we have ready-made engravings? The engraving plate is brushed with beeswax and filled with gypsum mud to get the mold of the engraving, and then the clay is pressed in the mold, and after the clay is dry, the gypsum is removed, and the clay plate can be obtained. ”

"It's rougher than the original, but it has the advantage of being convenient and fast. Turning out the required number of monochrome plates, removing the unnecessary parts on each color plate, and then finely carving and repairing them, is much faster than carving clay tablets. ”

"Waiting until the trimming is complete and sending it to the kiln to be fired into porcelain plates can save a lot of time."

Cheng Wenying happily slapped his thigh: "Photos!" This is the reason why the imperial court uses money to make money! ”

Lao Yu has long admired Su You: "The little young master is really a prodigy, and he admires it so much." ”

Cheng Wenying said: "Let's go, let's go to the pottery workshop now." ”

Su You said with a smile: "There's no need to rush this, you continue to finalize the details, first look through the plaster, the clay still needs to be tempered, and it also takes time." I went to the yarn line to learn rhyme. ”

Seeing Su You's small figure stepping onto the street, Cheng Wenying retracted his gaze: "I can't wait to have another daughter......

Lao Yu smiled at the thief behind: "Master, hurry up and take another room, in fact, it's still too late." ”

Cheng Wenying turned his head: "Get out!" Wait, will you be able to cast this plaster cast? ”

Lao Yu said: "Ouch! Patronized it and was glad! Master, hurry up and call the little master back. ”

So Su You just sat down and was arrested by Cheng Wenying again.

Now that tofu has been popularized, the application of gypsum Su oil thought it was very mature, but I didn't expect Yu Gong to even know this.
