"What is this, Master?" Luo Tian looked at the old wooden box placed on the rooftop table. It was already the afternoon of the next day, and it was only a dozen hours before Lu Tai'an left.
"You recognize me as your master. Although there is no formal ceremony, I can't be a master without showing any expression at all. I have received many one-sided comments in my life for making jade, but I never thought that I could accept someone like you in my lifetime.
Such an outstanding apprentice, this can be considered as our farewell gift to establish the relationship between master and apprentice."
Luo Tian was ashamed: "Master, even my disciples didn't think of this. I'm really ashamed."
Why didn't he think of a parting gift? Luo Tian was secretly annoyed.
"Open it and take a look."
Looking at the look on Lu Tai'an's face, one could imagine that the contents inside must be extraordinary. Luo Tian carefully opened the box and saw a wooden bowl inside!! A rosewood colored wooden bowl!!
Luo Tian was surprised: "A bowl?"
Lu Tai'an was very satisfied with Luo Tian's reaction: "Look carefully before talking."
As soon as Luo Tian's hand touched the bowl, his expression changed and he blurted out: "Muyu stone!!"
Muyu stone, Muyu stone, is a very rare hollow stone. Its scientific name is "Taiyi Yuliang", "Yu Yuliang", "Huangzi in the Stone", commonly known as "Resurrection Stone" and "Phoenix Egg", which symbolizes good luck and good luck.
Buddha's power is boundless and can protect all living beings, ward off evil spirits and eliminate disasters. Muyu stone is a famous mineral in China. According to research, it was formed about 550-580 million years ago. It is a precious jade stone, and its origin is limited to the west of the Taishan Mountains.
On the other hand, the Manshou Mountain area in Changqing District, which is listed as one of the three ancient cross-section specimen mountains in the world, has limited reserves and is extremely precious. Because its color, pattern and sound resemble the wooden fish that monks chant and beat, it is called wooden fish stone.
This is why Luo Tian thought it was a wooden bowl when he first saw it.
"If you use wooden fish stone utensils to hold wine (referring to liquor) for 24 hours, the methanol content can be reduced by 50%, and the fusel oil content can be reduced by more than 65%, while the alcohol content remains unchanged. Any white wine only needs to be placed in the wooden fish stone wine utensils for 20 minutes, that is,
It becomes soft, sweet and delicious, and the spicy and bitter taste is significantly reduced, which is obviously different from the wine served in other drinking vessels, so I use it as my drinking vessel."
"Master, such a precious wooden fish stone, I..." After knowing that it was a wooden fish stone, Luo Tian knew that this red sandalwood colored wooden fish stone was of the highest quality and the most valuable among the rare.
"Alas, I, Lu Tai'an, do not recycle the things I send out, let alone those given to my apprentices?" Lu Tai'an closed the wooden box and said, "Put it away!"
It was hard to reject the kindness, so Luo Tian took it with both hands respectfully: "I will definitely keep it well."
"That's decent." Lu Tai'an nodded with satisfaction: "I hope I can return to China in my lifetime and see you making a difference with my own eyes. You have just shown your feet in the antique world. I hope you can
It’s about showing off your talents.”
"Thank you, Master, for your message." Luo Tian already felt his heart racing. Yes, it's just the beginning, and the fun is yet to come.
"Today, I am teaching the last few methods of refining jade. The first is the acid etching method. The antique jade is put into strong acid to make the surface of the jade appear uneven. Some of them look like chicken bones after being corroded by strong acid.
White, and then dyed as needed. The general method is to put the jade in 10% hydrofluoric acid solution and soak it for about 4 to 10 hours. After taking it out, it will have the so-called "white gray skin". Or soak the jade in sulfuric acid solution
, in a mixed solution of nitric acid and water (the ratio is: 50% water, 25% each of sulfuric acid and nitric acid). If you want to add other colors to certain parts of the jade, use wax to remove the gray skin before soaking.
Seal the parts and isolate them.”
Lu Tai'an spoke very quickly, and Luo Tian quickly wrote down the proportions and timing. Lu Tai'an looked at Luo Tian's complacent expression and said seriously: 'Did I really remember it?"
"Yes, Master."
Lu Tai'an didn't quite believe it: "Then let me ask you, what is the ratio of sulfuric acid, nitric acid and water?"
"50% water, 25% each sulfuric acid and nitric acid."
Lu Tai'an was surprised. He spoke very fast. He didn't expect this guy to really remember it. Luo Tian continued: "Master, I will try it myself when I find a chance."
"Okay, I'm relieved now."
"Wind jade, also known as the method of imitating ox hair patterns. Boil the jade in thick gray water and ebony water, take out the jade from the heat, and freeze it in the wind and snow for about a day and night. The jade pattern will freeze and crack, and the jade will be hard.
, the cracks are as thin as a hair, and they are used to imitate the cow hair pattern in ancient jade. However, the cow hair pattern in real ancient jade is tortuous and uneven in thickness, and the fake one is unnatural."
Luo Tian nodded repeatedly: "I remember."
Lu Tai'an believed that he really remembered it, and said quickly: "Plum jade, use jade with a loose texture and poor quality to make utensils, and then steam them with high-concentration black plum water. Repeat several times, and the soft parts of the jade will become
It was hollowed out by black plum water, showing traces similar to those after water washing, and then painted with oil extraction method to pass it off as puddle ancient jade."
……………………
Time passed so quickly. Lu Tai'an didn't feel thirsty at all during this process. It was as if all the energy and burden contained in his body had been cleared away on this day. Suddenly, he felt a sense of joy that he had never felt before.
It's easy. He has been burdened with too much infamy in his life. At this moment, all the burdens have disappeared.
On the contrary, Luo Tian suddenly felt a sense of fulfillment that he had never had before. This sense of fulfillment gave him a power that he had never had before. The preparation of Dapeng before spreading its wings refers to this.
