"Rosewood is one of the most precious woods in the world, mainly produced in the tropical areas of the Nanyang Islands, followed by Jiaozhi. Guangdong and Guangxi in my country also produce rosewood, but the number is not large. The small-leafed rosewood in India, also known as chicken blood rosewood, It is the most precious wood known at present, and the highest among rosewood. As the saying goes, nine out of ten sandalwood is empty, and the largest rosewood is only about twenty centimeters in diameter, so the preciousness can be imagined."
"Red sandalwood is an evergreen sub-tree tree, five or six feet tall, with a complex leaf, a flower butterfly-shaped fruit, and its wings are very hard, red in color, and it sinks when it enters the water.Red sandalwood is a rare wood, also known as 'green dragon wood'
.Lexice family, evergreen large trees, odd-pinned complex leaves, butterfly-shaped corolla, yellow, panicle. Pods are flat and round, with wide wings around them. They are generally divided into two types: large-leaf sandalwood and small-leaf sandalwood. Small-leaf sandalwood is purple sandalwood
The most exquisite products are usually referred to as 'Red Sandalwood'. Rosewood is denser and has smaller brown eyes. It is mostly produced in tropical and subtropical primeval forests. Indian Rosewood is the best. The growth period of rosewood is extremely slow, and it only grows 3 cm thick every 100 years.
, it takes eight or nine hundred or even thousands of years to grow into a talent."
Luo Tian said: "During the Ming Dynasty, Zitan was valued by the royal family. Everyone knows that Zheng He went to the West, right?"
"I know!" Sure enough, Zheng He is quite well-known.
"The development of maritime transportation and Zheng He's voyage to the West, countries often have a certain amount of precious wood, including red sandalwood, in regular and irregular trade exchanges with China. But this is far from that of China's huge ruling group
It was far from meeting the needs, so the Ming Dynasty government sent officials to Nanyang to purchase. Subsequently, private traders also came into being. By the end of the Ming Dynasty, high-quality wood in various parts of Nanyang was basically cut off. In particular, the red sandalwood was almost completely covered.
He left with him."
"As of the late Ming and early Qing dynasties, most of the red sandalwood produced in the world were collected in China. All the red sandalwood used in the Qing Dynasty were collected in the Ming Dynasty. According to historical records, people were sent to Nanyang to pick red sandalwood in the Qing Dynasty.
, but most of them are thick and not full, and the curved joints are not straight. They cannot be used at all. This is because the rosewood grows slowly and cannot be made into a material for hundreds of years. It was harvested in the Ming Dynasty and did not resurrect in the Qing Dynasty. Its source is exhausted. This is also the rosewood.
An important reason that is cherished by the world.”
"Western people such as Europe and the United States attach more importance to red sandalwood than China because they have never seen big red sandalwood materials and believe that they can only be used as small objects. It is said that there is a five-inch-long red sandalwood coffin model in front of Napoleon's tomb. All visitors are surprised and think that
Rare. It was not until the late Ming and early Qing dynasties that Western missionaries came to China and saw many great red sandalwood objects that they knew that all the red sandalwood elites were in China. So they bought and transported back to China from many sources. Now the red sandalwood objects circulating in Europe and the United States are basically from China
Those transported there. Due to difficulties in transportation, they generally do not buy the entire item, but only those with patterns such as cabinet doors and box surfaces. After transporting it back, they are equipped with wooden frames for decoration."
"In the middle of the Qing Dynasty, due to the shortage of rosewood, the royal family also purchased rosewood from private merchants from time to time. The Qing Palace Construction Office recorded the purchase of rosewood almost every year. During this period, an unwritten rule gradually formed.
That is, no matter which level of official, as long as they see the red sandalwood, they will never let it go, and buy it as much as possible and hand it over to the royal family or weaving institutions in various places. After the mid-Qing Dynasty, all the wood stockpiled by private merchants in various places was bribed, and these wood materials were all bribed.
In the middle, a large number of them were used to decorate the Old Summer Palace and the Palace of the Supreme Emperor in the Palace; there was only a lot left after the Tongzhi, Guangxu wedding and Cixi's 60th birthday; by the time of Yuan Shikai, all the remaining red sandalwood was used up."
The students present only knew that the red sandalwood was precious, but they did not know that red sandalwood had attracted the attention of Western countries in history. They all listened with relish, and Gu Yuping was fascinated by the hearing.
"But teacher, there are still a lot of red sandalwood furniture on the market now. What's going on?" Many students were puzzled.
"More than 90% are impersonated by African sandalwood. Generally, the rosewood we recognize should be small-leafed rosewood. In addition to rosewood, there are also yellow sandalwood, green sandalwood, yellow sandalwood, and red sandalwood. Some are red wood, but some are not red wood.
It is because of the golden sign "Tan" that is posted, so it is very confusing. Everyone must distinguish it clearly in the future."
"Teacher..." As soon as a student opened his mouth, Luo Tian understood what they meant.
Luo Tian waved his hand: "I know, next I will tell you how to distinguish between red sandalwood. Red sandalwood is larger than water, and it will sink when placed in water. Use a sharp tool to scrape the red sandalwood. The lining is reddish brown, and it is on the surface.
The purple-brown color contrast is sharp. After a few days, the scraped surface will slowly turn purple-brown due to oxidation. Use thick alcohol to wipe the surface of the red sandalwood, and the alcohol will turn brown red. The more you cut it, the thicker the alcohol color will become. The surface will be wiped shortly after
Oxidize to purple-brown. The color of the red sandalwood carvings is the natural color of red sandalwood oxidation. There is no need to paint, just polish it with cowhide and waxing it. The surface of the big-leaf red sandalwood is black, while the small-leaf red sandalwood is brown; the big-leaf red sandalwood smells fragrant
Weak, even without fragrance, small-leafed rosewood has a fragrance. Generally speaking, it is best to collect modern rosewood utensils with small-leafed rosewood utensils."
Luo Tian picked up the piece of red sandalwood, and it was Venus Rosewood, and called a student: "Come on, follow my method just now, come and operate it on the spot and let the students take a look."
The student took out the keychain, and there was a knife on it. He scraped the skin of the purple trembling wood, and when he saw the color inside, he was amused: "Hey, it's really reddish-brown."
"Classmate, it's not okay for you to see alone. You have to share it with other students." Seeing that he was only concerned about researching on his own, Luo Tian couldn't help but remind him. The student smiled embarrassedly, raised it, walked down, and then said.
Let the students see, and the students nodded one after another. This method of physical teaching made them very excited. Some people grabbed the piece of red sandalwood and were reluctant to let go.
Gu Yuping had an idea and immediately walked out to find a container that could accommodate the red sandalwood. After finding a washbasin, he rushed to the bathroom and filled it with water. Then he carefully brought it over and delivered it to Luo Tian.
In front of him, Gu Yuping squeezed his eyes at Luo Tian, and Luo Tian smiled: "It's really a blessing to let Professor Gu be an assistant to me."
Gu Yuping glared at him: "Stop coming, this is the gift you gave me to find a scale for me just now!"
The funny conversation between the two attracted a burst of laughter in the classroom. Gu Yuping hurriedly retreated. The student was also clever and immediately took the red sandalwood to the stage and threw it into the water neatly. The piece of red sandalwood entered the water.
, immediately fell straight down and fell to the bottom of the basin. All the students said "Oh" and now it became clear.
Luo Tian looked at the time. The scheduled 45 minutes was not long. He cleared his throat: "Students, because there is not much time left, I will introduce to you another more precious one.
