Chapter 28 Jade Porcelain

On the other hand, Shi Da began to organize workers to put the new ware into the kiln.

Then use hay and coking coal, stack layer by layer, and ignite the fire.

The function of the hay is to help the coking coal burn more fully, and then the holes can be penetrated with long wooden poles plastered to control the oxygen intake and adjust the flame structure.

This is particularly important, for example, in the case of copper oxide glazes, which appear green at the oxidizing flame but red at the reducing flame, which can make a huge difference.

The glaze color of Jun kiln is rich in variety, that is, the kiln worker changes the flame composition in the process of firing, forces out the kiln change, and fires a colorful and rich glaze.

But this is the next step, now is to use the high temperature of coking coal to fire real bone china porcelain embryos.

Su oil is not as good as Shi Dong to repair Gao Yuan, and the choices are all small and medium-sized mud embryos.

Shi Dahe foreman looked at the situation in the kiln through the kiln eye, and couldn't help but be a little frightened, the fire color and flow cloth, uniform and stable, the temperature is extremely high, just like the legendary Laojun furnace.

A true connoisseur cares about these things.

When the firing was completed, the sagger was opened, and the crystalline snow-white objects shook so much that Shi Dongxiu couldn't open his eyes.

This quality is a huge grade higher than the porcelain plate that Cheng Wen should have taken away just now.

The function is different, the firing method is different, the porcelain plate is to control the error of each version to the minimum, according to the current new firing method, so that the porcelain clay inside a considerable degree of vitrification, will definitely cause the porcelain plate shrinkage ratio to increase greatly, and then lead to a huge error.

Now, however, the fine vitreous structure of the porcelain clay has brought a lustrous phenomenon to the new porcelain.

Shi Dongxiu held a cup, like a rare treasure: "What bone china, it's too ugly!" Jade porcelain! This is jade porcelain! In the future, it will be called jade porcelain! ”

Shi Da began to secretly slander again, you are embarrassed to grab the naming right, this should be the right of Mr. Xiao.

Su You didn't care: "Okay! Shi Shibo has obtained a good jade porcelain, which is more elegant than what bone china and bone ash porcelain. ”

Shi Dongxiu smiled and said, "Virtuous nephew, the old man got carried away for a while, forgot the rules......

Su You didn't care and said: "This name is already good, but if you want to really deserve the title of jade porcelain, you have to wait for the glaze to be reburned." ”

Shi Da patted his chest: "No problem, with the guidance of the little master, smelting a thin layer of glaze is much less difficult than sintering the carcass, Shi Da promises to do a good job." ”

Su You said: "Shi Da, today we will solve the problem of too thick glaze. In this way, bottles and other things, you first swing the inner glaze, and the process requirements are not high. As for the outer layer of thin glaze, as well as pots and bowls, when I went out of the city, I ordered a few things from the blacksmith shop by the city gate, and you sent someone to fetch them, and with that thing, you could really solve the problem of glazing. ”

At this time, Banniang and Twenty-seven Niang came over to greet everyone for dinner.

The general citizens of the Song Dynasty had two meals a day, and the wealthy people had three meals a day, and sometimes they even added supper.

Su oil is three meals a day in Kelong, even if you don't eat much at each meal, but they are all exquisite, and every meal is indispensable.

This is also the reason why the old uncle often scolds him, he is poor and rich, and eats the old man to death!

When the atmosphere of Demei Mountain changed, it seemed that everyone here felt sorry for him if he didn't eat three times a day.

Even the craftsmen of the workshop were stained.

After lunch, something was delivered.

This thing is very strange in the eyes of the Song people, it is a T-shaped copper pipe.

If you look closely, there are actually two of them, one is bent, and there is a hole in the bend, and the other is penetrated through the hole, and the two pipes are put together.

At the back of the straight pipe, a pump is connected.

Su You took the pipe over and checked the joints and the gaps in the joints.

The copper pipe is a red-hot copper skin wrapped diagonally on the iron bar and knocked out, the Huangyadong Arsenal used this method to process the steel barrel, it seems that the wisdom of the craftsmen of the Song Dynasty should not be underestimated.

Then the interconnected parts between the copper pipes are directly sealed with glue, and the chisel process is between the pump and the copper pipe.

It is very tightly combined, and this craft cannot be done by ordinary coppersmiths and blacksmiths.

A cork is punched through the copper pipe at the bottom, a porcelain bottle is filled with oil, and a wooden stopper is plugged to get a spray gun.

There should also be an air inlet hole in the cork to ensure that there is no low pressure in the bottle.

The principle of the spray gun is Bernoulli's principle, the high-speed airflow of the inner tube will cause the pressure of the inner and outer pipe walls to decrease, thus forming a pressure difference with the inside of the pot, causing the liquid in the pot to be sucked out, and then torn into fine mist droplets by the high-speed air flow.

The copper tube is very thin, the pump pushes very slowly, and there is not much glaze that can be sprayed per unit time, but it lasts for a long time.

The porcelain tire that had been glazed by Shi Dadang was placed on the turntable, and soon a uniform and thin glaze layer was sprayed.

This glazing method is definitely unique to the Great Song Dynasty now.

After waiting for the glaze to dry, it was fed into a sagger and filled with straw and coke again, and near evening, a new kiln of porcelain was re-fired.

The porcelain in the sagger is crystal smooth, white and flawless, and extremely solid. It is not an exaggeration to call it "jade porcelain".

The small kiln has not many things that can be fired at one time, sixteen small bowls, eight plates, two vases, and eight small wine glasses, and one below is a small wine corner with an open mouth on the conical head.

This set of white jade-textured porcelain came to the world for the first time, and everyone was so shocked that they couldn't speak.

Shi Dongxiu's hands trembled and stretched out to a plate in the pottery bowl, but he couldn't muster up the courage to take it out of the sagger.

I struggled a few times with shaking hands, and I was so anxious that I stomped my feet and shouted to Twenty-Seven Niang: "Hurry up and take it out and show it to Daddy!" This daughter! No eyes at all! ”

Twenty-seven Niang herself still felt a little weak in her legs: "Shi Da! Shi Da! ”

Shi Da is appraising the price of this kiln porcelain, and the people of the Great Song Dynasty especially like to search for odds, and a very fine whetstone can be sold for several pieces.

Well, scarcity is expensive, the first thing in the world to appear, a small bowl is a three-run, a plate is a five-run, two vases are a total of twenty, and the wine utensils are ten...... I'm a good girl, this small kiln is the bottom number of 100 times!

Porcelain rooster, this is a big deal!

Hearing Twenty-Seven Niang calling herself, Shi Da quickly took out the porcelain from the kiln bowl and washed it and placed it on the table.

Shi Dongxiu looked at this, touched that, carefully picked up the plate and gently tapped it with his fingers, and then picked up the plate and shone it into the sun.

Su You felt in a trance that all that flashed in his eyes under the sunset was real golden light.

I can't stand it! Su You found a box and put the small wine glass and small wine corner into it: "Banniang, let's go home and promise to get a good set of wine vessels for my in-laws, but we finally didn't break our promise." ”

When I returned home, I saw Cheng Wenying sitting on a chair and smirking, with a picture of Guanyin hanging opposite.

The thin black line is like a fine brushstroke, the set is very accurate, the stone blue of the ground rock, and the black of the stone on the bottom of the previous ink plate, constitute the effect of the law, Guanyin's skin is flesh colored, bamboo leaves, lotus leaves are emerald green.

The red goldfish and lotus flowers are very cleverly designed, and the tail and petals are created by pulling threads and large cut-outs to create the effect of excessive red and white, which is really similar to Gongbi at first glance.

Su You took a look: "It's amazing!" Yu Gong's craftsmanship is really convincing......"

Cheng Wenying turned around and saw that it was Su You: "Virtuous nephew, can the old history be over there?" ”

Su You said with a smile: "So that the in-law will know that Banniang will go to the kitchen to prepare, and I will give you a surprise in a while." ”

After a while, Banniang came up with a food plate, which contained a plate of lo-mei platter, a white jade-like wine corner, and a set of cups that only held four yuan.

Banniang put the wine and food on the cloth: "Grandpa, this is the porcelain that Uncle Xiao fired today." This plate of lo-mei, although it is also Uncle Xiao's recipe, is cooked by Banniang herself. Banniang's time has made Grandpa worried. ”

Cheng Wenying said with a smile: "Good boy, you are also for the family, but in the future, these things can no longer be hidden, you see, the matter is told to the virtuous nephew, isn't it easy to solve?" ”

After speaking, he picked up a cup and watched: "Dense and white, comparable to high-grade white jade." ”

Su You said with a smile: "Yes, Shi Shibo disliked that bone china was too ugly, so he gave it a new name, called 'Jade Porcelain'." ”

Cheng Wenying said hatefully: "This old man does not cultivate, and he dares to take away the right to name my virtuous nephew!" ”

After speaking, he said embarrassedly: "Uh, virtuous nephew, it seems that Shi Lao'er took this name, which is indeed more than bone china......"

Su You said with a smile: "I have no opinion at all on choosing the good one." ”

Banniang poured out a glass of wine from the wine corner: "Grandpa, grandma-in-law respects you Songzhu Rongxuan, Changqing Yongjian." ”
