The next day, the National Industry Standards Development Conference, Jade Cervical Branch was held normally.

Yesterday, Song Tao thought hard for a night, but his mind was broken and he didn't come up with any solution. He couldn't get Qin Qiongwen's technical details, and no one could find a loophole in something that could not be seen at all.

However, regardless of whether Song Tao has a clue or not, today's Jade Cervical Conference must be attended normally.

As expected by Song Tao, Qin Qiongwen was also sent to attend the Jade Chopin Conference, which was obviously intended to target the project Song Tao was responsible for.

Since Qin Qiongwen and Song Tao were several minutes late for attending the meeting yesterday, they led their respective participants to the conference room early today.

Song Tao noticed that when Qin Qiongwen came, she brought a group of people to move a large box to the conference room. The box was tightly sealed, and a group of staff were looking for a suitable placement, but they didn't know what was contained inside.

Song Tao pointed to the box and asked, "What's the thing that has been moved around? Is it true that Bao Xie wants to move?"

Qin Qiongwen stroked her hair and said with a smile: "Baoxi won't move, but this thing may allow you to move after you go back."

Song Tao said disapprovingly: "I currently live in Huachang City. Unless I resign, it is impossible to move in the short term."

When she said this, Song Tao gradually felt something was wrong. The more she spoke, the less her voice became. He looked at Qin Qiongwen with a strange look and asked, "You mean, this thing can make me fired by the quality inspection center, right?"

"Smart." Qin Qiongwen gave a thumbs up.

Song Tao shook his head: "Don't believe it."

However, Song Tao's tone was a little weak. After all, Qin Qiongwen's resume was too amazing. Who knew what she would do to trick her into.

Just as the two were chatting, representatives from the Standard Management Committee, industrial and commercial testing, and business circles arrived one after another. The host of the meeting was Liu Xi of the Standard Management Committee.

"Dear delegates and attending members, if there is no problem, let's start the meeting." Liu Xi suggested.

After seeing everyone nodding in agreement, Liu Xi emphasized the meeting matters and stated the current status of the current industry standard on the chalcedony regulations. After completing all these processes, he entered the representative's speech time.

Song Tao sat in the first place this time, so it was his first turn. Under the gaze of everyone, Song Tao took out a bag of Zimbabwe green chalcedony samples.

Song Tao said: "Team leader Liu, dear delegates and attendees, the industry standards of chalcedony have not changed at all for two consecutive sessions. This is because chalcedony is in the middle and lower level of the jade category, and no new minerals are found with good commercial properties, so the attention has always been unsatisfactory."

"But the situation is different now. Yunshi Mining Group discovered this new green chalcedony ore in Zimbabwe, Africa. In the past, the green chalcedony on the market were all artificially dyed with variegated chalcedony. Now there are natural green chalcedony varieties. I think the trademark should clearly distinguish the two."

Song Tao pushed the bag of Zimbabwe green chalcedony samples into the middle of the table and concluded: "So, Huachang Dida's opinion is to include the identification of the cause of the color formation of green chalcedony in the industry."

Liu Xi copied his speech in his notebook and asked: "Representative Song, the prerequisite for incorporating the color identification of green chalcedony in Xingbiao is that the technical standards are met. What do you think?"

Song Tao said lightly: "It is only possible to distinguish whether green chalcedony has been dyed and only use a spectrometer to observe, which has been concluded in the academic community."

Liu Xi nodded and continued to remember Song Tao's speech seriously in his notebook.

However, after Song Tao finished speaking, Qin Qiongwen suddenly retorted: "Technology is constantly developing. Representative Song said with certainty that green chalcedony dyeing only requires a spectrometer to distinguish it, but that is probably a thing of the past."

Song Tao frowned. Jiang Zhongtuo led the school experts to review the proposal on Jade Cervical. No one has ever raised any questions about the technical issues of dyeing and identification. Why did Qin Qiongwen suddenly say that using a spectrometer is not possible?

Song Tao asked in confusion: "Representative Qin, what do you mean?"

"Everyone, wait a moment." Qin Qiongwen stood up and made a gesture to the other personnel from the treasure association: "Come on the pot."

pot?

Song Tao frowned. His first reaction when he heard the "pot" was that the meal was about to start.

Of course, this is definitely not the case. I saw several staff members of the Baohui Association move the box to the conference table and place it in the center.

"Open it." Qin Qiongwen ordered.

Song Tao had a bad premonition and subconsciously stood up to see what was contained in the box. The other participants who were present also stood up and got around the box.

After the box was opened, I saw a hollow cylindrical metal bucket with a bottom inside, and the walls and bottom of the bucket were very thick.

Song Tao frowned: "It's really a crap?"

"No, right." Song Tao quickly identified what the pot was from its shape: "Is this a reaction kettle?"

"To be precise, it is the sample cavity of the large cavity press. I temporarily removed it from the main machine." Qin Qiongwen corrected.

Then Qin Qiongwen emerged a green cylinder with a diameter of one centimeter and a height of about half a centimeter from this sample cavity. She smiled at Song Tao and said, "Can you recognize what this is?"

Song Tao stared at the green cylinder that was twisted in Qin Qiongwen for a while, and then said in surprise: "Is this artificial synthesis of green chalcedony? Did you synthesize green chalcedony using high-temperature and high-pressure method and a large cavity press?"

When Song Tao said this, he had a little sheep sound - trembling.

Synthetic gemstones are not ordinary counterfeit products. The physical properties and chemical properties of synthetic gemstones are almost no different from their corresponding natural gemstones. The only difference is that one forms mineralization in nature and the other forms in laboratory equipment.

The history of human synthesis of gems has lasted for more than a hundred years. As early as 1877, French chemists Fremy and Ferre used the crucible method to synthesize rubies. In more than a century since then, flame melting, lifting, hydrothermal synthesis, vapor deposition and other methods have emerged one after another.

Of course, the current synthetic gems are similar to natural gems, and there will always be a little different under high-precision instruments.

It can be said that since the birth of synthetic gems, the technical game between appraisers and engineers has never stopped.

The originator of the principle used by Qin Qiongwen to synthesize green chalcedony is the American GE Company, which used this high-temperature and high-pressure method to synthesize jade for the first time in 1984.

However, this technology is extremely costly and has narrow application and has not been valued by the academic community for decades.

It is no exaggeration to say that the entire Internet papers about this technology can be counted with one hand. Song Tao never expected that Qin Qiongwen would use this rare technology to synthesize green chalcedony.

Song Tao only felt his heart was so cold.
