Something that can be solidified from a liquid state, soaked in water, may be useful.

And this box, which also has a layer of black paint inside, is not afraid of blisters, you can try it.

There was ready-made pure water in the room, and Yu Yao first dipped it in his hand and wiped it on the surface of the beads, which felt similar to ordinary glass.

"Pour water on the bubbles, if it's useless, then it can't be harmful, if it's useful, we'll observe and deal with it at any time!" Lin Feng said causticly.

Yu Yao nodded and poured water. Then he lit a cigarette and watched from the side.

This kind of wrapping looks almost transparent, but it is difficult to say what color or very fine texture it has, and you can only see it when you take out the beads.

Although when I used a carving knife before, the situation was not very good. But after soaking in the water, the situation is much more optimistic than they thought.

After about ten minutes, it can be clearly seen by the naked eye that the surface of the bead seems to have softened.

Yu Yao touched it lightly with a toothpick, there was a sense of piercing, but it couldn't be pierced, and it was plucked at the bottom again, and the beads seemed to have a slight shaking.

Lin Fengcao looked at it, "Pour out the water and try it!"

Yu Yao poured the water from the box into a cup, but the beads were still attached to the groove at the bottom of the box.

Then, Yu Yao simply probed the edge with a toothpick to provoke, feeling that the adhesion was still there, but it was not inseparable.

Yu Yao and Lin Fengcao exchanged tools, tried several times, and finally got the beads out of the groove and "transferred" them to an empty cup first.

At this time, the surface of the bead, the transparent wrapping looks a little soft and trembling, and the surface also has a certain sticky feeling, but it still does not detach from the bead.

"Since this is to protect the beads, it shouldn't be corrosive!" Lin Fengcao said, directly reaching into the cup and trying to knead it.

After kneading, the surface of the beads is slightly deformed, but I feel that this layer of wrapping is still relatively tough, and it cannot be broken or peeled off.

Lin Fengcao let go and sniffed his fingers, there was no obvious smell.

Yu Yao picked up the bottle of pure water, "Since water can separate the surface, then continue to bubble?"

"Okay!" Lin Fengcao nodded.

Yu Yao poured water into the cup and continued to soak the bead.

At this time, Lin Fengcao cleaned the bottom of the box with his hands. There is no black lacquer in the semicircular groove exposed at the bottom of the box, and looking at the bottom, it should be Nanmu.

Most of the lacquered woods are relatively cheap woods that are not easy to deform, because mahogany is more valuable, and lacquering is a kind of painting snake to add to the problem, and the cheap wood is all in the cork category, among which fir is relatively the most used. Pine wood is not good because it is easy to produce oil.

As for Nanmu, it is also a cork, the wood is not as dense as mahogany, and it is not easy to deform, and it does not like to produce oil. However, nanmu is almost the most expensive wood other than mahogany, and very few are lacquered to make things.

The tire of this black lacquered wooden box is actually Nanmu, which shows that no expense is spared, and what stands out is a skill.

After the box is wiped dry, it is intact. And this bead, in the clear water in the cup, has also gradually changed.

The wrapping on the surface seems to have increased the intensity of decomposition, and the originally relatively smooth wrapping has a rough feeling, a bit like peeled grapes. This "roughness" refers to the surface, and the texture of the wrapper itself gives people a feeling that is still very delicate.

This time, Yu Yao and Lin Fengcao didn't rush to do it, and waited for half an hour, and the beads finally became no longer round, and became a random "hanging paste" shape, and this cup of pure water also changed color.

It has turned into a beer-like yellow.

Lin Fengcao took a closer sniff, but there was still no obvious smell.

"I think it's okay. Yu Yao said, stretching out his hand. Lin Fengcao nodded.

Yu Yao tried this time, the touch was like lime plaster, and after rubbing it in the water a few times, the wrapping fell apart!

"It's done!" Yu Yao was pleasantly surprised, and then took out the beads, and Lin Fengcao immediately poured pure water into a transparent cup and let Yu Yao put it in first.

And after Yu Yao took out the beads, the wrapping in the beer-colored glass of water also changed further, and finally turned into a cup of suspension. This shows that there are water-soluble and water-insoluble substances in this package.

Yu Yao and Lin Fengcao didn't have time to pay attention to this, but stared at the beads in the pure water.

Looking at it this way, it is completely different from the original look through the package!

I can see it very clearly.

This bead, which should be about 1.8 cm in diameter, has a blackish-gray purple color on the surface, and is not yellow. The color of yellow that I saw before should be caused by the wrapping.

"Pearl!" Lin Fengcao blurted out.

"Black Pearl!" Yu Yao added, "Such a big black pearl is still perfectly round, unheard of!"

Judging from the current market situation, the volume of black pearls is mostly about one centimeter in diameter, and most of them will not exceed 1.1 centimeters. Black pearls of more than 1.5 centimeters, and they are still perfectly round, they have never appeared on the market, and their value is difficult to estimate for a while.

"It's a big deal! I didn't expect it to be inlaid with a black pearl!" Lin Fengcao tapped his finger on the wall of the cup, "If there was no such wrapping, the pearls of the Ming Dynasty would have turned into powder long ago!"

There are many people who like pearls, but there is one biggest problem, that is, they cannot be stored for a long time, and the lifespan is about the same as that of people. Even if you are careful, the maximum shelf life is about 100 years.

As the so-called old pearl yellow, because of the material, after the pearl is preserved for decades, to the time period when the person is old, it will generally turn yellow first, dull and dull, and more than 100 years, it will basically dry up and powder.

However, some pearls of extraordinary quality have undergone special care and may have a lifespan of two or three hundred years, such as the Dongzhu Dynasty pearls of the Qing Dynasty that can be preserved in some museums or on the market.

But further up, that's less likely. If someone takes a string of pearls and tells you that it is from the early Qing Dynasty or even the Ming Dynasty, do you think you don't believe it?

Of course, this black pearl is beyond the scope of conservation, but sealed!

The wisdom of the ancients should not be underestimated. However, with the development of technology, it is not difficult to seal a pearl with a special material and store it for a long time, but the problem is that it is impossible to wear and enjoy it.

This black pearl, if it hadn't been taken out and wrapped inside, it wouldn't even be able to tell what material it was.

Lin Fengcao rubbed his hands, "By the way, you said that there may be craftsmanship?

Yu Yao nodded, carefully took out the black pearl in the cup, dried it, put it on the soft cloth on the table, and said while observing the surface: "I was even whimsical just now, it can't be a 'Nine Curved Bead', right?
