Chapter 146 Devitrification of enamel
After Wen Biquan finished speaking, he took the initiative to pick up the little jade elephant and said to Bao Qianqian: "You are holding the Tianqiu bottle!" ”
Bao Qianqian saw that Wen Biquan was very interested, and he also wanted Wen Biquan to have more knowledge, so he said to Wen Biquan: "Okay! Come with me and I'll show you the real experts here! ”
As he spoke, Bao Qianqian carefully picked up the Tianqiu bottle, opened the door of the office, and took the lead towards the studio of the chief treasure connoisseur of the auction house.
went down one floor, turned left and went straight to the innermost, stood at the door, Bao Qianqian carefully knocked on the door with his hand, then pushed the door open and walked in.
Wen Biquan also followed and walked in, and when he looked up, he saw a spacious and bright laboratory of more than 100 square meters, with several clean and tidy experimental tables arranged in the middle.
A thirty-eight or nineteen-year-old young man wearing glasses and overalls entered her field of vision, neat and exquisite, elegant and a little bit of jumping, seeing Boss Bao coming in with a porcelain vase, standing up and walking over quickly, respectfully greeted her.
He nodded and smiled, "Boss Bao!" The boss came in person and brought the baby again? I love to appreciate the baby brought by the boss! ”
"Less sycophants! I'll introduce you to it later! Bao Qianqian glared at the visitor and said.
The person who came cautiously took the Tianqiu bottle in Bao Qianqian's hand, looked down, his eyes quickly fell to the Tianqiu bottle, and he couldn't stop shouting: "Wow! Amazing, good stuff! ”
Bao Qianqian ignored the startled colleague, turned to Wen Biquan beside him and introduced: "This is our team's chief treasure connoisseur Chen Zhipeng, Brother Chen!" In terms of identification, he has strong professional ability! ”
Wen Biquan smiled and nodded.
Immediately afterwards, Bao Qianqian said to Chen Zhipeng, who was focusing on the porcelain vase: "Brother Chen, don't look at it, there will be time to watch it for a while!" I would like to introduce you to an important person, this is Wen Biquan! Last time, I brought back Hetian Yutian, and Tianlu Yuzhen was her treasure. Her baby will be more than me in the future, and it's okay, keep it for you to see enough! ”
"Wow! Really? Tianlu Yuzhen is hers? So young? I really didn't expect it! …… Boss, did you just say those things with your sister's consent? Did you mean it or did she mean it? Or is it ......? Haha, I'm more interested in this sister! In the future, my sister and baby will take me here for identification! Give me a chance to feast my eyes on it! Chen Zhipeng quickly raised his head, his eyes moved from the Tianqiu bottle, and he looked at Wen Biquan and said with a slight teasing, and then he had a slightly flattering charm.
"Of course! With Brother Chen, how can there be someone else's share? It must be a feast for Brother Chen's eyes! And it will also allow you to enjoy the treatment of 'exclusive home, no other semicolon'! Wen Biquan also responded with a smile and a half-joking smile, and peeked at Bao Qianqian again after speaking.
"Don't be poor! Less of her idea! Wen Biquan is my girlfriend! Go and help me take a good look at this, I'm sure you'll be surprised! Bao Qianqian saw Wen Biquan's glance out of the corner of his eye, and hurriedly took over the conversation.
Although Bao Qianqian knew that Chen Zhipeng quickly guessed the relationship between the two people, Bao Qianqian still patted Chen Zhipeng's head and jokingly said the above words, officially indicating the relationship between the two people.
Wen Biquan instantly felt that he had a unique face in front of his colleagues, and he was also happy to walk beside him and appear in front of his circle of friends.
"Yes! Boss! Boss, you are free, I'm busy! Congratulations to the boss for successfully getting rid of the single and finding true love! In the future, it will be blessed with all the blessings, and the longevity will be better than the sky! Chen Zhipeng didn't joke about his boss, but who could refuse a mouth full of compliments and blessings?
Then he obediently ran away with the big guy in his arms.
Wen Biquan also glanced at Bao Qianqian with a smile, shook his head and said with a smile: "Your relationship is very good!" It looks like it's in harmony and comfort! ”
"Of course! The friendship of life, the brother of life and death! Bao Qianqian restrained his smile and said to Wen Biquan seriously, "Let's go, go over and take a look!" ”
Wen Biquan didn't say anything about him anymore, and when he looked around, he saw all kinds of experimental instruments placed on the experimental table, tall, short, fat, and thin, standing quietly there one by one, waiting for someone to open it.
Wen Biquan looked at the instruments on the table with novelty, and unconsciously said the names of the instruments in his mouth: "Carbon 14 analyzer, thermoluminescence analyzer, devitrification spectrometer, scanning electron microscope, X-ray diffractometer, infrared absorption spectroscopy, ......and these, there are no names!" ”
Bao Qianqian accompanied Wen Biquan around the laboratory, and then came not far from Chen Zhipeng, quietly watching him busy with his work.
Chen Zhipeng first opened a set of instruments, and after preheating, the surface enamel of the porcelain bottle was detected by non-destructive devitrification spectroscopy to check the degree of devitrification of the enamel on the surface of the porcelain, and then the aging coefficient was calculated to determine the approximate production age of the porcelain vase.
This technology was created specifically to deal with high-imitation fakes.
Because the porcelain glaze is a sub-stable glassy homogenizer with a disordered structure after firing, in the natural environment, the internal structure gradually transforms to an orderly crystal stable state over time, forming microcrystals and showing the phenomenon of devitrification, which is the evidence of the natural aging of porcelain enamel.
It is manifested as a gradual decrease in light transmittance, an increasing increase in light scattering, and a soft and warm glaze is seen.
And even if the porcelain enamel of the old-fashioned high-imitation fake is still in a glass state, the glaze color still has "thief light" and "fire".
Vitrification is a natural evolution over time, and it is not possible to artificially fire new porcelain with aging bubbles. Therefore, the devitrification identification of porcelain enamel has become the only way to identify imitation fakes.
Therefore, Chen Zhipeng's first item is to do a devitrification test of the Tianqiu bottle, verify the body, and determine the age. It didn't take long, and the results came out, this Tianqiu vase is about two or three hundred years old, and it belongs to the porcelain works of the Qianlong period of the Qing Dynasty.
Chen Zhipeng also found out the porcelain sample with Qianlong porcelain, used a portable microscope to observe the surface bubble state of the two of them and compared, and compared the writing font and style of the inscription, and finally came to the conclusion: it is a Qianlong pastel nine peach celestial ball bottle in the Qing Dynasty.
When it was finally confirmed, Bao Qianqian and Wen Biquan were not very excited, but Chen Zhipeng was very excited, "Boss! You've sent it again! The reserve price is at least more than 20 million! ”
"Don't get excited, it's not mine, it's hers!" Bao Qianqian coldly interrupted Chen Zhipeng's imagination, pointed at Wen Biquan and said to Chen Zhipeng, "Issue an appraisal report, the person who submitted the appraisal report belongs to her name!" ”
When Wen Biquan heard this, he was startled and really shocked.
This Bao Qianqian is too generous! This was obviously bought by two people together, and he used his 150,000 yuan, but he gave it to himself without blinking?
If it were someone else, would he be able to do that?
An inexplicable feeling of gratitude lingered in his heart, Wen Biquan did not have too much hypocrisy, accepted it calmly, and said with a smile: "Thank you!" It's my name! ”
Chen Zhipeng also retracted his excitement just now at this time, and said with a smile: "It's better if it's my sister!" You can also entrust us with an auction! Then again, yours is also the boss's, and it's all the same in my eyes! ”
"Brother Chen is right, entrust your auction house to be in charge of the auction! But you're not done yet, and here's more! After speaking, Wen Biquan took out the little jade elephant from his arms and carefully placed it on the table in front of Chen Zhipeng.
