The trick of soaking bronzes in vinegar is generally only used by archaeological teams and museums, because this is a comprehensive and indiscriminate treatment, which can be described as a nuclear bombardment!

If Tufuzi and private collectors obtained bronzes, they would treat them with vinegar in local locations unless they were sure that an important inscription was covered with patina, which would increase the value of the artifact. Pen ~ fun ~ pavilion www.biquge.info

But you must grasp the degree, otherwise there is no place to cry!

Because if the time is too long, vinegar will basically eliminate everything on the surface of the bronze, including the patina, including the pulp left over the years, which is fatal to the Tufuzi: the value is all in the pulp, without that layer of things that will be formed over the years, how many buyers will recognize your antiques?!

Museums can not care: all kinds of records are sufficient, and they do not sell them.

……

This will have vinegar, and this will be easy to deal with: because the most simple and crude method will be used, holding the copper plate directly to the kitchen, putting the large copper plate on the ground, and then opening the vinegar bottle.

It was already 9 o'clock at this time, and only a few followed: the bodyguards did not participate in the boss's secrets, and the fireworks outside had temporarily stopped, and my sister had already taken her little nephew and asked Yongqiang to send her home first.

My brother-in-law won't leave for the time being, it depends on Zhang Nan's rust removal method.

Zhang Nan went to find a mask to bring on first, and he was not happy when he smelled vinegar!

"Gas masks or not? Karimina has two. ”

As soon as he heard Guan Xingquan's words, Zhang Nan shook his head: "Brother Guan, I'm allergic to vinegar, eat it." It's not terrible!"

"Big brother, are you sent by the monkeys to be funny?"

I didn't say anything in the last half of the sentence.

Even Nicole and Jenny are here, you asked me to wear a gas mask to operate this, those who know are probably laughing, and those who don't know think that this is "Lethal Poison"!

It's vinegar, not a highly toxic chemical.

When the bottle is opened, whether it is white vinegar or rice vinegar, it is poured into the large copper plate, and it is necessary to ensure that it does not spill out, and the outside cannot be corroded.

After pouring fifteen bottles, there was still a section from the edge.

"Tang Gui, give me a pot of boiling water. ”

"Oh. ”

Comrade Chef Lisuo handed over the boiling kettle, and Zhang Nan poured half a pot of hot water at least 90 degrees into it, this is to control the acidity, and the second is to increase the heat, which can speed up the speed of rust removal.

took a bamboo chopstick and stirred it: there was a small amount of hot steam, the clean and tidy kitchen was filled with a smell of vinegar, and Zhang Nan was a little uncomfortable wearing a mask.

It's faster to heat the vinegar and pour it in, but it's too much to eat!

03 During the SARS period, almost all units and buildings used rice cookers with open lids to heat vinegar for fumigation and disinfection, which caused Zhang Nan to be smoked enough everywhere!

Painful memories that must not be made.

Straightened up and said, "Okay, it will take at least half an hour for such a thick patina to bite off, and it may take a night to scatter!"

Others are embarrassed to follow up, but brother-in-law and Brother Guan, Nicole and Jenny, as well as two "landlords" and chef comrades, plus themselves stuffed in the kitchen, this is enough to squeeze.

Zhang Nan was the first to retreat, passing through the door and through the dining room to the living room, and Xiang Weirong at the back motioned to Tang Gui to look at the big copper plate and followed.

Nicole and Jenny were curious, squatted down for a long time to look at this strange shape, but there was a kind of ancient thick beauty of the bronze, and soon they couldn't stand the pungent sour smell and left the living room.

My sister went back first just now because Jia Nan was still young and needed to go to bed early, and as for the others, even if they only came back today, it was still early to rest.

When they arrived in the living room, the two women sat next to Zhang Nan, and Andy Lu, who also arrived in the living room together, saw the situation and felt that his chef was a little inappropriate here, so he went back to the kitchen and went to accompany Tang Gui: In fact, he can go to rest, but he feels that the boss may need to help himself later, so he is embarrassed to go.

What if the boss is looking for something in the kitchen and can't find it!

Xiang Weirong and Guan Xingquan also took a turn in the living room and left first, going to Qiu Bo's dormitory.

The bodyguards just met to play poker: the capital of the soldiers, they will also add some small chips, and tomorrow is the New Year, killing time.

It's the same with the beauties, you can also play Texas Hold'em together.

Anyway, I said it for at least half an hour, and I want to come back after watching the excitement.

Here, Nicole and the two are asking what that big copper plate is.

I know it's an antique, but I don't know anything else.

"Alan, how old is that thing?"

"Almost 2,800 years ago, the high-grade bronzes of the Western Zhou Dynasty in China were used by the high-ranking nobles to wash their hands. ”

"Oh!"

The small meaning of nobility or nobility: two women are not stupid, they know what it meant in that era!

Around 800 B.C., 28 centuries ago!

The Battle of Thermopylae between the Greeks and the Persian Empire would not take place until 320 years later, Alexander the Great would not be born until more than 400 years later, and Gaius-Julius Caesar would not be born until nearly 700 years later!

2,800 years ago, apart from China, the ancient Egyptians were probably the only ones in the "third intermediate period" and began to conflict with the Assyrians, who had built a strong army at that time.

To put it bluntly, ancient Babylon and ancient Egypt were going to fight, and the former finally beat the latter half to death!

As for ancient India, then hehe......

India's ancient civilization was only discovered in 1922, and you can imagine what the ancient Indian civilization thousands of years ago left behind in today's India!

Of the four ancient civilizations, only the history, culture and people of China have been handed down, and the other three have long been things and people!

People have changed one stubble after another, not to mention culture.

The Chinese civilization is not the oldest in the world, but it is the only one that has survived!

This is the greatest thing about Chinese civilization!

As for ancient Greece in the west, the Cretan civilization disappeared around 1400 BC;

Between 1100 and 1000 BC, the invasion of the Dorians destroyed the Mycenaean civilization, and Greek history entered the "Dark Ages".

It was not until the first Olympic Games in 776 BC that the ancient Greek civilization began to flourish.

For Westerners, around 2,800 years ago is a very important period: because the ancient Greek civilization, one of the main sources of Western civilization, actually began at that time, and then lasted for about 650 years: 800 BC - 146 BC.

……

At that time, two American women could imagine how noble it was to use such a beautiful piece of art as a toiletry in such a distant era!

I didn't ask where it came from, I can't do it!

"The Ball at the Moulin Rouge" was hanging right in front of them, and it was not surprising for two American women to pull any unexpected artwork out of their man's hands.

It can't be helped, it's hard for Americans to tell the difference between artifacts, antiques and art. < br>

"Alan, what are you pouring vinegar into that big basin?"

It was Jenny who asked about it: Americans originally didn't eat rice vinegar, but sometimes they would eat fruit juice vinegar and red wine vinegar, which would of course be strange for Zhang Nan's behavior.

Zhang Nan didn't say the reason for doing this in the kitchen just now.

Sitting in the middle of two beauties, I feel that my own women are fragrant, very good, much more comfortable than the pungent vinegar smell just now!

"I'm removing the patina that covers the inside, and it's covering the words cast in the copper plate underneath.

It's a professional job that ordinary people can't do. ”

"Chinese characters 2,800 years ago?"

"Of course it's kanji! Zhang Nan scratched Jenny's nose, "It's the grandfather of the grandfather of the Chinese characters we use today......

After many evolutions and developments, many characters are written differently than now, but they are just not easy to recognize, and they are Chinese characters.

And some of them are exactly the same as the way Chinese characters are written today, such as the ...... of production."

Nicole and Jenny are also learning Chinese, and they can still understand this: Chinese characters are the only highly developed morpheme script that is still widely used in the world, and the morpheme scripts that have developed maturely and represent a high level of culture in history include cuneiform script in West Asia, sacred script in Egypt and Chinese characters in China!

The first two scripts are now recognized by only a very small number of professional scholars, because they are long since "dead"!

Only Chinese characters remain, starting with the oracle bone inscription of the Shang Dynasty around 1300 BC, then the Zhou script, the Jin script, and then the small seal of the Qin Dynasty, and then to the Han Dynasty, and then to the Tang Dynasty Kaihua into the handwritten font standard used today - block letters.

Chinese characters are by far the longest continuously used script, and they are the only ones that have been passed down to this day in the major writing systems of antiquity!

"It's a wonderful feeling to know what people were doing 2,800 years ago!"

Nicole laughed and said, "Understand, things are dead, but words are alive." ”

"That's the reason. ”

Zhang Nan had been chatting for a while, then looked at his watch and said, "Almost, go see how it is." ”

When I returned to the kitchen, I saw that all four people were there, but none of them touched the copper plate on the floor.

"Anan, it seems to have changed color inside. ”

It was the brother-in-law who spoke.

When these vinegars are added together, the color is originally reddish, but this will become a little cloudy, and there are a lot of black slag at the bottom, which is a small amount of patina that has been corroded.

The discoloration is the original patina, commonly known as "patina", which has completely turned black.

"Normal, see how much bites come off. ”

Zhang Nan squatted down, picked up the chopsticks he had just used, and directly scratched the bottom of the basin a few times, and suddenly the slag rose up!

"It's still almost, I guess I won't be able to do it in three or five hours, I knew I would do it again tomorrow. ”

The vinegar worked, but it didn't completely gnaw off the patina of a lot of thickness, so I could only continue soaking.

Zhang Nan is not like some people in museums, who dare to soak things overnight before talking! Looking at this situation, he will not be able to sleep until the second half of the night tonight.
