Chapter 381 380. Inventory Collection (3)

Sophie was going to work, and Li Du took Ah Ao outside.

There is a large lawn in the hospital, and many people are recuperating. He took the pup to the grass. The pup was exposed to the sun and the wind, as if he had been given a stimulant, and immediately regained his energy.

Don't look at Ah Ao's short legs, and he can't run easily when he was born, but he is still very majestic on the lawn.

It's just that it's too small, the lawn is uneven, and there are potholes in some places, and it's easy to fall into it while running.

He is young, small, and has weak legs. Once Ah Ao falls into the pit, he can't climb up, so he can only yell and yell non-stop.

At noon, Li Du invited Sophie to have a meal.

There is a music restaurant in Flagstaff City, with a very high-end style. It is full of small private rooms, and different music is played in different private rooms.

The two chose a private room for piano music. Sophie explained the piano music to him, and Li Du introduced these dishes to her. They had a great time eating.

In the afternoon, Hans called Li Du and said, "I contacted a furnishing store. They have experts in mahogany. I want to ask them to identify the identities of these woods."

Li Du was also very concerned about this. He first went back to the room in the crown of the pine tree to look at a few precious treasures, and then returned to the camp.

Among the treasures in his collection, the most valuable one should be the Trossi-Leggenda watch on his hand. There is no need to worry about it being stolen, because he always wears it on his hand.

The second is the gem saber he picked up from the Arabs. This knife is inlaid with beautiful gems, the blade is sharp, the material is exquisite, and the handle and scabbard are made of ivory.

But what really multiplies the value of this knife is its owner's identity. Li Du has used the ability to reproduce time to see that the owner of this knife is either rich or noble.

One of the last masters he often sees in the news is the supreme leader of Libya, Omar Muammar Gaddafi.

Even without Xiao Chong's ability, he could find the knife. In some news about Gaddafi, his desk sometimes appeared, and the knife was placed in the center of the desk.

It's a pity that there is no introduction about this knife on the Internet. Li Du guessed that it is not a legendary knife, but was collected by Gaddafi only because it used a lot of rare materials.

In addition, there are papyrus that he does not understand. He has not deciphered the words on these papers, and he does not know what is written on them.

These three things are in his private collection, and there is an aboveboard specimen of a dodo skeleton on the table.

This thing doesn't belong to him anymore, but he is still very satisfied when he thinks that a specimen can be exchanged for a million dollars.

When he arrived at the camp, the mahogany experts had already arrived. They were a middle-aged Chinese man and an old white gentleman. They brought tools to the camp.

Hans introduced them and said: "This is a compatriot with you, his name is Antonio Su, and his family has been engaged in mahogany research. There is also this gentleman named Bart Kerry, who is an expert in wood and furniture. .”

Li Du shook hands with the two of them, and Antonio Su asked in awkward Chinese: "Nihao, Li, you are very popular with people, I am lucky to be in Jiangnan."

His Chinese made Mr. Li very shabby. Mr. Li introduced himself, and then opened the wooden box, revealing the tree trunks inside.

Seeing these tree trunks, the two looked at each other and nodded at the same time.

Seeing this, Hans happily asked: "Is the result very optimistic?"

"Needs identification, but from the looks of it, the results look promising," Butt said.

Li Du asked: "From the appearance, what can you tell?"

Antonio explained, and he said: "These woods belong to different varieties of mahogany. As you may know, mahogany is divided into 33 species, and they are all different in appearance."

"Take this as an example," he said, pointing to a purple-red tree trunk. "This looks like red sandalwood, and it looks like Indian small-leaf red sandalwood, a very precious tree species."

Li Du said: "I'm also learning about this recently, but according to what I know, the appearance of the African red sandalwood is very similar to this."

Antonio smiled and said: "With all due respect, you may have acquired knowledge, but you are still inexperienced. The color of Indian red sandalwood is red at first, and then gradually becomes darker. Compared with African red sandalwood, there are patterns in the purple, and it is oily. Don't do it."

"African red sandalwood is purple-black, dull, with thick fibers. After drying and shrinking, there are many cow hair patterns, which is very ugly."

"If it's a bit mysterious, it's the same red sandalwood, the small leaf red sandalwood is a living wood, and other red sandalwood is dead."

While Antonio was introduced, Bart moved into action.

He solicited the opinions of the two, and after obtaining permission, he cut off a small piece from each tree trunk, and then divided it into several smaller pieces for different treatments.

He took a small piece of each kind and put it into a small beaker, added some solvents into it, and sliced ​​some of them under the microscope, and processed them in various ways.

Hans was surprised when he saw it: "Is the inspection so complicated?"

Bart smiled: "Of course, it will take five or six hours."

Hans looked at Li Du and said, "All of us lack knowledge of mahogany. So when we were in Holbrook, we did something stupid."

Some of them called their friends to describe, some took photos to show their friends, and some made videos, thinking that they could identify the true identity of Hongmu.

It turned out that these methods were very low-level and unreliable.

Among the redwoods, the most precious one is red sandalwood, and the first thing the two of them inspected was purple red wood.

Bart took out a piece of white paper. He took a piece of wood and scratched on the white paper. He drew more than ten lines in a row, all with purple-red marks, and the marks remained unchanged from the first to the last.

Li Du asked: "Isn't it possible to determine its identity?"

Bart said with a smile: "Sir, you don't know how advanced the counterfeiting technology is now. Using potassium permanganate mixed with iodine and litmus solution to soak some wood can be faked."

As he spoke, he chopped some sawdust from the wood chips, put them into a glass filled with clear water, and said, "We can wait, and we will use fluorescence detection to identify them later."

"It shouldn't be a big problem." Antonio, who was observing in front of the microscope, raised his head and said.

Li Du leaned over to the microscope and looked at it. The cross-section and fiber texture of the wood were magnified many times in the lens.

He couldn't see anything, but for Antonio and Bart who were in contact with wood every day, the information revealed by the microscope was too much.

Antonio is a good teacher, and said: "This is a 30-fold mirror, which is the most authoritative method for physically judging the message of mahogany. Of course, it must be combined with other physical methods. Do you want to know?"
