Chapter 790

After working for more than three hours, the old farmer was finally a little tired. During this period, he wrote a total of more than [-] characters.

After putting down the pen, the old man suddenly found several people standing in front of him, and was shocked.

Yang Dongsheng gave the old man a thumbs up, and the old man smiled with a simple and honest face.

At this time, Director Li's elder nephew, who is proficient in calligraphy and painting appraisal, came over. He first said hello to Yang Dongsheng, then picked up a piece of calligraphy, and quickly frowned.

"Huang Wenjie's characters still have vulgar meanings, rhymes and Jin..." He took out a red pen and drew circles on the characters while talking, "These few places are only resembling in shape, but not in spirit!"

It was only then that Yang Dongsheng realized that the previous exercises were just practice.

It wasn't until seeing the third work that Director Li's nephew nodded and said, "This one is not bad!"

Qualified calligraphy works were picked out individually and put aside.

In the end, among the twenty or so characters, a total of seven qualified ones were selected.

Five of them are Huang Tingjian's - just looking at Huang Tingjian's handwriting, this old man's pass rate is 50%, and he is really good at imitating Huang Tingjian.

It wasn't until this time that Liu Weiguo asked someone to take out the carefully purchased paper and ink.

According to different times and regions, the materials used in calligraphy and painting works are also different.

Some calligraphy works are made of paper, some are made of silk, and some are made of silk.

Before the Tang Dynasty, paintings on silk were mostly used, but after the Tang Dynasty, paintings on paper gradually increased.

Even paper, there are hemp paper, leather paper, bamboo paper, cotton paper, rice paper, mulberry paper...

It took a lot of effort just to collect these papers.

Now the paper industry, sodium hydroxide and sodium sulfide for pulping;

Chlorine and calcium hypochlorite are used for bleaching, and sulfamic acid is added to reduce cellulose degradation and maintain cellulose strength;

Sizing uses synthetic glues such as alkyl ketene dimer and alkenyl succinic anhydride.

Where did these things exist in ancient times?

The ancient artificial paper bleaching method is to spread the material on the open space, let the wind and the sun shine, and bleach naturally.

Polishing was first done by rubbing the surface of the paper with a smooth stone, and later gradually evolved into wetting the paper with a slurry, and then beating it repeatedly with a mallet.

Starch paste is used for sizing, and animal glue is used for advanced paper.

Nowadays, it is very rare to make paper using the ancient method, and many paper making techniques have even been lost, so we can only buy paper left over from ancient times at a high price.

This kind of paper is really one less.

So they have to practice repeatedly to make sure nothing goes wrong.

The emphasis on ink is even more complicated.

Su Shi once said: "I have Jiamo Seventy Pills, but I am still asking for it."

Su Shi not only has a rich collection of ink, but also likes to make ink by himself.

Fortunately, compared with paper, most people can't tell the quality of ink. Otherwise, if you want to get the ink made by Su Shi himself, it will be difficult to die.

This time, the old man was not as casual as before. He deliberately changed into a clean suit, and rarely washed off his oily hair. It took more than an hour to finish writing a line, and each stroke was as heavy as Tarzan.

Director Li's eldest nephew nodded after appraising it.

Then it is to stamp various seals on the work, and finally use it to make it old.

The old scene was a bit offensive, and Yang Dongsheng walked out quickly.

I was seeing the expert in charge of appraising porcelain shaking his head at a tri-colored horse figurine of the Tang Dynasty.

"What's wrong?" Yang Dongsheng asked.

Seeing that it was Yang Dongsheng, the other party quickly said hello, and then pointed to the horse figurine and said, "This three-color fly-wing pattern has been done so many times, but it still looks too rigid!"

"Fly wing pattern" is a form of natural cracking of porcelain.

The expansion coefficients of the base layer and the glaze layer of porcelain are different. After high-temperature firing, natural cracking will appear after cooling.

However, during the use of ancient porcelain, it repeatedly expands with heat and shrinks with cold, absorbs water, dehydrates, and the density of brittle cracks will gradually increase.

The longer the porcelain, the more serious the natural cracking phenomenon.

The Tang Dynasty has a history of more than 1000 years. If the porcelain from that time can be preserved to the present, there will be dense cracks on the surface. At first glance, it looks like the lines on the wings of flies, so it is called "fly wing pattern".

Ru kiln's crab melon pattern and fish roe pattern;

Cow hair patterns, gold wire and iron thread patterns of official kilns in the Southern Song Dynasty;

……

These have almost become rigid indicators for authenticity.

Of course, there are exceptions. Ru kiln celadon narcissus basins without patterns are not opened, and are called divine products by porcelain lovers.

Now this artifact is in Yang Dongsheng's hands.

There are many ways to make porcelain old since ancient times.

Relying on the current equipment, they first put Tang Sancai in an autoclave to fully expand and absorb water, and then put it in an electric oven to bake and dehydrate.

Then, before the porcelain cools down, it is cooled with carbon dioxide immediately.

After repeating this many times, if the porcelain is not broken, "fly wing patterns" can also be made.

However, the imitation "fly wing pattern" always looks stiff, like formatting.

The "fly wing pattern" that has been formed naturally for thousands of years should be natural, agile, delicate and soft.

"It is said that there is a master of Tang Sancai in Yu Province. The Tang Sancai he made can fool the experts in the Huajing Palace Museum. I have asked for help, but he is unwilling to come to Shanghai. I am going to Yu Province. If If he can do it, I want to entrust him with all the Tang Sancai in the future! Do you think so?"

"Yes!" Yang Dongsheng nodded and patted the other person on the shoulder, "Don't be afraid to spend money, don't be so careful, and don't stick to one place. There are many talented people in the country, so we must fully mobilize them. It is a great event through the ages. Our current speed is too slow, and my idea is to vacate the National Palace Museum in Taipei within three years, and then there will be the Louvre, the British Museum, and the Tokyo National Museum waiting for us!"

Yang Dongsheng had already negotiated with Jason Bourne about the business of the Louvre, the British Museum, and the Tokyo National Museum, but before even a deal was made, Jason Bourne died, and the matter was shelved up.

Looking for an opportunity, Yang Dongsheng wants to find out about David Webb and see if he is willing to take over all of Jason Bourne's business, and even go a step further and include the Metropolitan Museum of New York.

Both Yang Miao and Yang Yue had their summer vacation, and Yang Miao was still studying and managing the company as in previous years.

In Nanjiang Shipyard in Shanghai, the construction of the first ship of the second batch of China Aegis ships officially started.

The China Aegis is my country's first warship equipped with a phased array radar system and a vertical launch system.

The service of this type of warship enabled the Navy to have long-range area air defense capability for the first time.

But since the launch of the first two destroyers in 2003, nothing has happened.

In the previous life, our country did not start the construction of the second batch of China Aegis ships until 2008. The reason was that the Changxing Island shipbuilding base was not completed, and more importantly, it was stuck in the power system.
