"Dear Wu, what treasure made you all the way to the Middle East?"

Wu Tianyuan looked at Tagil, who was very enthusiastic, and said with a smile: "Can't I come to see your good friend?" ”

"Hahaha, okay, please come in!" The two of them came to the garden and chatted over tea. Pen, fun, pavilion www. biquge。 info

"I just received an invitation from Bonhams for the special mountain residence, and Tianyuan Hall, is it your newly created hall number?"

"Yes, I have nothing to do to get some antique porcelain to play with, the effect is not bad, this time I am also looking for Yuan Qinghua raw materials, Su Ma is away from Qingqing, and there are some clues."

Tagil's eyes lit up and he asked with interest, "Oh? Can you, the treasure hunt master, go out, and it seems that nine out of ten are safe? ”

Wu Tianyuan smiled slightly, did not answer, and asked rhetorically: "I also came today to ask for your help, the clue is in the mountains of northern Iraq, if you really find mineral deposits, do you have the ability to get the mining rights?" ”

"No problem, I still have a little face in Tagil!" He said confidently: "It's not a gold mine, leave it to me to deal with." ”

"That's good, I won't let you do it in vain, wait for Yuan Qinghua to be imitated, count it as you, and all the sales in the Middle East will be handed over to you!"

Tagil laughed, a little disapproving, if Wu Tianyuan hadn't said this, he would have laughed at someone else! Just kidding, Yuan Qinghua has been imitated by countless people for hundreds of years, and none of them have succeeded. Su Ma is a key to leaving Qing, but there are still many recipes lost, otherwise the Middle Eastern tyrants would not have collected Yuan Qinghua with hundreds of millions.

Wu Tianyuan did not explain, and it is nonsense to say anything without results, as long as Su Ma Li Qing Ore can be mined, Yuan Qinghua will solve the biggest problem.

He did not stay long, entered the mountains of northern Iraq through Tagil's connections, and finally found a deeply hidden target two days later.

Su Ma Liqing is a low-manganese high-iron iron cobalt material, cobalt oxide Coo, the color is dark blue, it is the most stable coloring agent. Whether it is fired repeatedly or under any glaze, it has a stable blue color. 0.25% cobalt oxide gives a brilliant blue color in the glaze.

Cobalt deposits are abundant in northern Oman in Iraq, and the use of cobalt in local pottery was widespread in Abbasi times.

When the Abbasid caliphs received jade-like porcelain from China, which had to be brought back from China after a year-and-a-half-year voyage due to the preciousness and fragility of the porcelain, the caliphs built their own kilns to fire imitation Chinese porcelain.

Porcelain shards excavated in Samarra prove that the first pottery fired here was entirely a replica of Chinese Xingyao white porcelain, and the lack of significant kaolin made it impossible for the imitation ceramics to be essentially high-temperature porcelain.

Samarra is rich in cobalt and is a porcelain-making center for the mass production of underglaze blue and white ceramics, and at the same time very close to Baghdad, the final destination and distribution center of China's blue and white porcelain trade since the Tang and Song dynasties, especially during the Yuan and Ming dynasties.

It is not known when the cobalt blue material was brought to China by merchants, but from the special color of early Chinese blue and white porcelain such as Hongwu, Yongle and Xuande in the Yuan Dynasty and the Ming Dynasty, combined with literature and modern chemical analysis, it can be clearly proved that Su Ma Liqing is a cobalt blue material from Samarra, Iraq.

After Wu Tianyuan discovered the ore vein, he wrote down the coordinates, found Tagil, and asked him to dredge up the relationship to deal with the mining permit issue. After all, it is a Middle Eastern royal family, and this little thing is a breeze. In less than a Sunday, Yuan Mining officially moved in and began small-scale mining.

"Boss, did you really find Su Ma Liqing?"

Old Tang looked at the cobalt material in his hand incredulously, and hurriedly began to test the ingredients with the machine to see if it matched the glaze color and hair color after the Yuan blue and white firing.

Yuan blue and white has several characteristics, rust spots are the most typical characteristics of Su Ma from the green material, in the accumulation of green materials, such as the pen and the pen, the intersection of the two strokes, the pen, the tire, etc., is the place with the highest probability of rust spots.

The reason for the formation of rust spots stems from the chemical composition of high iron and low manganese in Su Ma Liqing material. Through the scientific instrument determination of the black spots of blue and white porcelain tiles, the iron content in the black spots is several times higher than that in the blue and white materials.

There is also halo, which is a blurred and unclear visual phenomenon at the boundary between the blue and white pigment area and the non-pigment area, like ink splashing on rice paper and spreading outward.

The reason for the halo is that the viscosity of the blue and white pigment and glaze decreases and the fluidity increases at high temperature, resulting in the diffusion of the blue and white pigment from the coloring area to the non-coloring area, forming a natural halo effect.

Yuan blue and white porcelain glaze is made of calcium-alkali glaze, and the melting effect of CAO reduces the viscosity of the glaze at high temperature, makes the glaze more easy to disperse, and increases the halo effect of the pigment.

"Boss, you see, when observing the color of Yuan blue and white under a high-powered microscope, you will find a phenomenon, in the pigment area, there are often dot-like black spots condensation, especially on a long line decoration, there will be a wonderful dark dot-like spot like a string of pearls, this phenomenon is described as bead-like condensation."

"After the detection of modern scientific and technological means, it has been proved that the typical tin light reaction in the Yuan Qinghua cobalt material is due to the crystallization of manganese iron oxide, which shows that the tin light is the same as the principle of rust spot formation, which is due to the enrichment of iron oxide, and the crystalline patch of this iron oxide will form tin light under the refraction of light."

Wu Tianyuan has a lot of Yuan blue and white in his hands, so that Lao Tang can study it carefully, and even scrape off a part of the glaze and analyze the composition with the most advanced instruments, which is very luxurious.

"Here are some secret recipes in my hand, you combine the family heirloom to see if you can copy it successfully? Let's discuss it in detail when the finished product comes out. ”

Now the kiln factory has money and some people have raw materials, Ming and Qing antique porcelain is the old Tang Dynasty's housekeeping skills, the production line is very mature, at least 600 pieces of fine products can be produced every month. The newly launched Longquan celadon and kiln are improving their technology, up to 300 pieces this month, but after the new equipment and talents are in place, it will reach almost 1,000 pieces per month.

Now he has time to start studying Yuan blue and white, this number is not much, and the five famous kilns of the Song Dynasty are the same, and they are the top antique porcelain. After he needs to experiment with his own hands, he can only find a craftsman with the highest level to complete it.

"Yuan blue and white also has glaze, which requires top painters to complete." Geng Lao said with a smile: "Brother Ruguan Jun is all monochrome glazed into the kiln, and what conquers people's hearts is the elegant shape, and the texture of warm and jade, which can only be perceived by the old Tang and their hands, and there is no possibility of industrialization." ”

"I know that, but I can't industrialize it." Wu Tianyuan nodded in approval and said: "Yuan Qinghua and the five famous kilns must be few and fine!" Even if there is only one finished product in a month, it is enough to be a representative of the highest level of Tianyuantang! ”

"When the time comes, it will be auctioned, so that collectors all over the world will know our antique level, and Tianyuantang will definitely become the first number of antiques in the future!"

Wu Tianyuan has a plan, antique porcelain can be mass-produced is the Ming and Qing dynasties and celadon kiln kiln, according to different quality, divided into three grades of high and low sales to the international market. Blue and white were mainly European, and the aristocracy liked luxurious and delicate patterns. Celadon and Jianyao Dingyao all entered the Japanese market, and they were aesthetically appreciative of these monochrome glazes.

As for Yuan Qinghua, once it succeeded, it was mainly sold to Middle Eastern tyrants through Tagil, and the highest quality was auctioned and became one of the signboards of Tianyuantang.

Not to mention the three famous kilns, Brother Ruguan is an absolute heavy weapon, even if it is antique, it is also a star product. The real product in the world does not survive more than 100, and it is also a rare fate to have one piece of antique porcelain. (To be continued.) )
