There is a young man named Chen Xiaosi in the family, who has clear eyebrows and beautiful eyes, and is also quite spiritual, with four hands like tender bamboo shoots, very delicate, and he has learned to make many porcelain styles in four or five days. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info Sun Lang saw that he could teach his son, so he rewarded him with gold, and taught him some more complex and elaborate porcelain styles. Gooseneck bottles, chicken bowl cups, halberd bottles, fish basket bottles, general jars, pankou pots, Fushan furnaces, double fish washing, flower gourds, slag buckets, etc., nearly 100 porcelain styles, but everything that Sun Lang saw in later generations was depicted on paper with a brush and compiled into an atlas, all of which were handed over to Chen Xiaosi to study and ponder slowly.

When Chen Xiaosi saw Sun Xianggong exalting himself like this, he had to work harder and harder, and studied all kinds of porcelain in this atlas day and night. The rest of the people saw that the drawing skills were good, and they could still be rewarded, and they also competed and practiced.

The previous one dried and became a solidified porcelain fetus, so Sun Lang picked up a bamboo skewer and carved it repeatedly on the tread, carving exquisite patterns. The surface of porcelain can only be called a fine work of art if it has a texture, otherwise it is no different from those ordinary clay pots and bowls of the Qin and Han dynasties.

Although this craft requires skill, it is one of Sun Lang's best jobs, and he used to cast patterns on iron tools, and this is especially handy for carving on the surface of this carcass as thin as glutinous rice.

Sun Lang carved and painted a pair of "Zhang Liang picking up shoes", which tells the story of Zhang Liang and Zhang Zifang, one of the three masters of the early Han Dynasty, picking up straw shoes for the old man, and was later presented with the story of "Taigong Art of War" by the old man. The grass and trees, mountains and rivers on the pattern, the appearance of the characters, and the action instruments are all vividly and vividly.

Chen Xiaosi led a few people to pull out the blank shape, and the carcass after drying was continuously sent, like an assembly line. Sun Lang showed his strengths and carved all kinds of patterns onto the tread. Some are "Taigong fishing", some are "soldiers crossing the customs", some are "two elders admiring the moon", and some are "five sons Dengke". Not only allusions, but also pure scenes, such as "Meilan bamboo chrysanthemum", "high mountains and flowing water", "Luo Shen Ayabo", "a hundred birds and a phoenix", etc., in short, all kinds of patterns with beautiful meanings in later generations, he carved them, a wide variety, too many to mention.

More than a month has passed, and Sun Lang's porcelain production line has hoarded a large number of carved carcass. During this period, Dong Xi went back and forth three or four times, and each time he brought back Cai Wenji's letters, and Sun Lang was also happy to take time out of his busy schedule to reply to the letters.

And Cao Ajiao often came to visit her husband, personally served him tea and poured water, wiped sweat and beat his shoulders. As long as it suits her at night, no matter what Sun Lang is busy with during the day, she has no complaints. Not only that, but on the contrary, it was full support, and if anyone dared not listen to Sun Lang's orders, he would be rewarded with a violent beating, until he swore that he would never dare to disobey again.

During this period, Sun Lang re-counted the ore consigned from the imperial treasury, and saw that although there were many patterns, only one cobalt ore was missing. This cobalt ore is rich in cobalt elements, and when heated at high temperatures, it will form cobalt oxide, which can leave a touch of indigo pattern on the carcass of porcelain, which is the famous blue and white porcelain.

In order to get cobalt ore, Sun Lang went to the imperial treasury and told the arsenal order: "After the cobalt ore is crushed, if it is mixed into the iron slurry of the smelting weapon, it can increase the toughness and corrosion resistance of the weapon, and it can not help but improve the strength, and it can also avoid the frequent rust of the weapon due to the age, so why not seize and mine some cobalt ore for weapon smelting?" ”

Although the arsenal Ling was skeptical, he listened to what Sun Lang said, and he seemed to be an expert, so he ordered a large group of soldiers to go to the mountains to mine cobalt ore. Sun Lang described in detail the appearance and texture of the cobalt ore, which is steel gray in color with slight white spots, and hard in texture with a metallic luster. The soldiers searched for more than half a month, and found many similar stones, but none of them were cobalt mines, and finally had no choice but to send a senior old miner to finally find this ore in the mountains hundreds of miles away.

Wu Ku Ling received an order from above, saying that no matter what, he would support Sun Lang with full assistance, and no matter what he wanted, he would supply it together. Since he got the cobalt ore, he ordered the official workshop under the jurisdiction of the imperial court to crush all of it into fine powder, put it in jars, and send it to Caofu in batches.

The metallurgists in the arsenal sprinkled this cobalt ore powder into the iron slurry, and the smelted spear was indeed much sharper and stronger than before, and the tip of the blade was slightly blooming with blue light, which made people feel frightened at first sight. Not only that, this spear has been placed in the open air for more than ten days, whether it is wind and rain, or water and dew dripping, there is no rust at all, and I can't help but be amazed, and one by one I stretched out my thumbs and couldn't stop praising it, saying that this Sun Gongzi is really in a word, and he has been smelting weapons for most of his life, but he knows such a trick for the first time. The arsenal Ling was overjoyed, and while taking this improved blade to the upper mission to ask for merit and reward, he also ordered his subordinates to grind all kinds of ores into fine powder, and send them to Sun Lang for his use without any impurities.

In this way, Sun Lang once again obtained the necessary raw materials for the preparation of blue and white porcelain without much effort. Not only that, but it also saves a huge amount of work to break up and grind the ore into powder.

Cobalt ore powder is mixed with water, stirred and mixed into a dark black liquid, dipped with a brush, and evenly applied along the previously drawn ridge line like a painting. After the cobalt glaze is painted, the surface is then coated with a layer of clear glaze, which can increase the brightness and luster of the porcelain. This is a delicate job, and the glaze must be applied in a uniform thickness without defects such as sagging and thin glaze.

After all the porcelain tires have been glazed, it is time to open the kiln.

The porcelain tires are packed into the pre-prepared boxes one by one, and they are moved one by one into the small homemade kilns made of adobe bricks, and then neatly stacked together. The so-called box is a container made of mud tires, the purpose of which is to prevent the porcelain blank from direct contact with the kiln fire and avoid the pollution of fire ash and soot.

The kiln door is sealed with mud, leaving only a small opening to measure the fire, the fuel of the kiln is pine firewood, which is not only resistant to burning, but also can minimize the fire smoke. When the pine wood is lit, the fire suddenly rises, and through the small hole in the mouth of the kiln, you can see that all of it has become a sea of red fire.

The control of the kiln temperature is extremely important, and it is generally controlled at a high temperature of more than 1,000 degrees. Sun Lang used a long iron rod to reach into the kiln every half an hour, and measured the temperature by how hot the iron rod was for a fixed time. This is also a commonplace craft for him, and a blacksmith who can't even control the temperature of the furnace can't train a sword at all.

If the temperature of the furnace is low, order someone to fan the fire, and if it is high, you need to stop adding firewood. More than a dozen family members waited at the other end of the kiln, holding firewood in their hands and waiting at any time. At the other end, there are five or six housekeepers pulling a huge bellows, fanning the fire in the kiln.

This lasted for nearly a night, and near the ugly hour in the early morning, Sun Lang ordered everyone to stop adding firewood and fanning. By the early morning of the next day, the fire in the kiln gradually subsided, and finally naturally subsided into a few wisps of green smoke, which was extinguished. Sun Lang had a confident smile on his face, knocked on the kiln mouth with a hammer to ventilate, and after another half a day, when the temperature in the kiln returned to normal temperature, and the smoke and dust had almost dissipated, he ordered people to go in and take out the clay boxes one by one.

The moment the clay box was peeled off, all the people who had worked hard for months had a puzzled look, not knowing what was hidden inside. As if waiting for the birth of his child, his face was full of hope and expectation.

The dirt on the crate had been burned black by the fire, and with a light blow of a hammer, it peeled off layer by layer. It seems that the silkworm chrysalis broke through the cocoon and turned into a beautiful butterfly, and it is indeed a piece of porcelain as white as clotted fat and as bright as jade!

Moreover, these sparkling porcelains are also painted with a variety of pale cyan patterns and patterns, which look so elegant and dignified, warm and auspicious...... (To be continued.) )
