Master Archaeologist

Chapter 257 Whole Extraction Method

After washing with the watering can, Chen Han soon figured out the situation of the "bottom of the bed".

There are three lacquer boxes and three gold boxes.

Two of the boxes are gold cakes, and one box is the rarer horseshoe gold, or Linzhi gold!

Gold horseshoes are generally used as imperial rewards, gifts, dowries, large transactions and extraterritorial exchanges, and are not currency in circulation.

However, it still needs to be weighed in the specific use process, so it is also a weighing currency!
Gold prevailed in the Western Han Dynasty, with gold as the unit of calculation.

The form of gold is influenced by the state of Chu, and the shape is usually cake-shaped, and there are also forms such as persimmon gold, horseshoe gold, and Linzhi gold.

"Han Shu Wudi Ji": In the second year of Taishi (95 BC), "in March, the imperial edict said: 'There is a minister who said, those who go to the suburbs of Zhen will see God, go to Longshou in the west, and get Bailin to give to the ancestral temple. There are celestial horses coming out of the hollow water, and there is gold in Taishan Mountain, so it should be renamed. Today, the gold is changed to Linzhi and Haoshoe, to help auspiciousness and auspiciousness.'”

Horseshoe gold has already appeared in the earlier state of Chu.

But when it came to Emperor Wu of the Han Dynasty, Emperor Wu of the Han upgraded it to Linzhi Gold!
In fact, the workmanship is more exquisite.

And the workmanship of these "horseshoe gold" discovered by Chen Han this time is very exquisite, and what is even more rare is that these horseshoe golds have not deformed!

As we all know, gold is a very soft metal and is very easily deformed by external forces!
But thanks to these three boxes of gold, they were all placed under the same bed.

And this bed is very strong, and it has not collapsed in the past 2000 years.

As a result, the three boxes of gold have not been oppressed by external forces.

The last box of Linzhi Gold still maintains a complete "Linzhi" shape, which is actually a bit like a horse's hoof and a bit like a donkey's hoof.

However, at the "hoof root", there is a surrounding pattern. This pattern is very exquisite, using fine gold craftsmanship, and even a lot of colored glaze with a diameter of only a few millimeters is even inlaid on it!
Let's put it this way, if you are a person with trypophobia, you will get goose bumps when you see this pattern!

Before BC, being able to achieve such precise craftsmanship was equivalent to letting a modern person make blades for an engine by hand.

"Exquisite, so exquisite!"

"These three boxes of gold are really well preserved."

After hearing the news, Kong Jianwen and other people from the Institute of Archaeology, Academy of Social Sciences, were surrounded by excitement.

Locate, scan, take pictures...

A process unfolds in an orderly manner.

Without the slightest hesitation, Kong Jianwen decided to extract the three boxes of gold first.

It's just that after all the preparations are done, the extraction can start.

Everyone is in trouble.

These three lacquered wooden boxes have been soaked in water for 2000 years, and they are already as soft as noodles.

They can still maintain the shape of a box, and they can still hold the gold, all thanks to "inertia".

It's just because there has been no external force to break this balance.

But if the archaeologists want to pick up these boxes, they will definitely be smashed into pieces, or even turned into powder!

How to put these three boxes of gold that have been placed in this 2000 years and soaked in silt and water has become a difficult problem.

"Although the gold box is severely damaged, it is still a lacquer box from 2000 years ago."

Kong Jianwen touched his chin, thought for a while and said, "Let's extract it as a whole."

"Go get some steel bars."

As soon as these words came out, Chen Han's eyes lit up immediately!
He knew how Kong Jianwen was going to extract these lacquer boxes.

Chen Han quickly ran to a place where "archaeological tools" were placed, and took a few steel bars with a length of more than 20 centimeters, and a plastic hard board measuring 1 meter by 2 meters.

Holding these things and returning to the archaeological site, Chen Han casually handed the steel bar to Zhuang Yunpeng, and then took out a ballpoint pen from the jacket pocket of his work uniform with "Academy of Social Sciences Archeology" printed on it.

Bite off the pen cap with his teeth, holding the big plastic board, Chen Han walked to the side of the three lacquered wooden boxes, propped the plastic board four or five centimeters above the lacquered box, according to the size of the lacquered box, Make a few marks on the plastic board.

"Where are the scissors, bring some scissors!"

Lin Ya quickly handed Chen Han a pair of large scissors in her bag.

According to the marks he made, Chen Han cut out three plastic boards with a length and width of [-] centimeters.

Seeing this scene, Kong Jianwen smiled with satisfaction.

This disciple's brain is still very flexible, and he can see through a little bit.

He didn't give any pointers, and just stood beside him with his chest folded, watching Chen Han play.

Chen Han didn't panic at all, raised his head and shouted to Zhuang Yunpeng: "Brother Zhuang, insert these steel bars into the bottom of the box."

These steel bars are very thin, maybe only a few millimeters thick.

But this kind of steel is a special kind of steel, which is very tough, and it can withstand a weight of more than ten catties if it is only a few millimeters thin.

Three or five can bear thirty or fifty catties together.

Zhuang Yunpeng also understood what Chen Han was thinking, he smiled, and stepped forward to get busy.

Don't look at Zhuang Yunpeng's appearance, but he is also known for his ingenuity in the Institute of Archeology of the Academy of Social Sciences, and his hand skills are very good.

It is this advantage that Kong Jianwen has taken a fancy to!

Zhuang Yunpeng held the steel rod in his hand, and after a few gestures, he neatly inserted the steel rod into the gap between the bottom of the box and the mud.

The movements are precise and fluent!

After inserting four steel rods in a row to drag the bottom of the entire box, Zhuang Yunpeng stopped.

Then Chen Han handed Zhuang Yunpeng a cut plastic board that was a little bigger than the box.

Still doing the same operation, Zhuang Yunpeng quickly inserted the plastic plate under the steel bar again.

Yes, that's how this lacquer box is extracted in its entirety.

Since the lacquer box itself can no longer bear the force, it is necessary to reinforce the bottom, and then lift the reinforcement at the bottom to extract the lacquer box together.

It's a simple, clumsy solution, but it works very well.

After the steel bars and plastic plates were inserted into the bottom, Chen Han specially sprayed a soil separator on the bottom of the paint box and the underground soil and silt to prevent it from sticking together.

This is a chemical agent researched by the Cultural Heritage Protection Center. Chen Han doesn't know the specific ingredients, but he knows that it works very well.

No matter what sticks to the mud, just spray it on and let it sit for a few minutes to let the mud separate naturally!

After waiting for a few minutes, guessing that the mud underneath had separated from the bottom of the lacquer box, Chen Han directed Zhuang Yunpeng to pull out the inserted steel bars.

Then it was replaced with a larger steel plate, which was reinserted under the plastic plate.

In this way, a layer of plastic plate and a layer of steel plate appeared under the lacquer box!
Chen Han and Zhuang Yunpeng only need to hold the two corners of a steel plate to lift the lacquer box!
