Organic gemstone - 玳瑁

"玳瑁", I believe that most people who have studied jewellery or people in the coastal areas have rarely heard of it. However, after watching the newly-developed drama of the New Year, "Yue Yue Chuan", everyone should be "玳瑁" This vocabulary is no stranger to it:

In fact, the "玳瑁" is not a small one, let Xiaobian tell you.

It was originally a marine animal of the sea turtle family. It is generally about 0.6 meters long and 1.6 meters long. The main living areas are shallow lagoons and coral reefs. Many caves and deep valleys in the coral reef provide a place to rest. The coral reef also houses the main food, the sponge.玳瑁 is the only turtle that can digest glass. The foods also include invertebrates such as jellyfish, sea anemones, shrimps and shellfish, as well as fish and seaweed. The carapace and scales are amorphous, and they are slightly transparent to translucent. They have a waxy to oily luster and can be made into eyeglass frames or decorations. A piece can be used as a medicine. Distributed in the vast sea area. However, excessive fishing has made cockroaches an endangered species, and it has almost disappeared in China's coastal waters.

Pelicans are large and fierce carnivores in the ocean, often found in coral reefs, mainly preying on fish, shrimp, crabs and mollusks, as well as seaweed. It has a strong ability to move and swim faster. I like to eat on coral reefs, continental shelves or shoals filled with brown algae. Although cockroaches are omnivorous animals, the main food is sponge.

玳瑁 - Organic Gems

An ornament made of a horny structure such as a carapace and a scale is a kind of organic gemstone.

Many cultures have the use of enamel crafts. In the famous poem of the Han Dynasty, "Peacock Flying Southeast", there is a poem "The foot is squatting and the head is shining".

Sima Qian’s "Historical Records of Chunshen Jun Biography" records: "Zhao Pingjun makes people in Chunshen Jun, Chun Shenjun is in Shangshe. Zhao wants to boast, why, the sword room is decorated with beads, Please call Chun Shen Jun guest. Chun Shen Jun guest three thousand monks, their guests are all squatting to see Zhao, Zhao made a big sigh." The meaning of this passage is that Zhao Guoyuan, the emperor of the emperor, when he came to Chu, for the spring Shen Jun showed off his head and wore a sword with a beaded jade. When he saw the 3,000-door guest of Chun Shenjun, everyone saw their shoes in the big pearls. This shows that during the Warring States Period in China. , 玳瑁 jewelry is already a very popular men's jewelry.

In the Tang Dynasty, Yan used to make coins - Kaiyuan Tongbao, unearthed in the underground Tibetan palace of the Famen Temple in Xi'an, which is very precious, only 13 in the world.

The scales are crystal clear, the pattern is clear and beautiful, the color is soft and bright, and the craft ornaments made with it are dazzling, and the treasure is Huasheng, the taste is noble and elegant. In the eyes of the oriental people, since ancient times, it has been a symbol of auspicious longevity and evil spirits, and has won the love of royal aristocrats, rich people and even the general public. Wu Zetian, the emperor of the Tang Dynasty, used 玳瑁 bracelets and earrings. The Song Dynasty people loved 玳瑁, and they used the pattern and color of the clam shell to create a beautiful and realistic black glaze.

During the Ming and Qing Dynasties, the use of enamel products seemed to be more common. Up to the palace, wearing jewellery, down to the literati's study wenwan, such as small screen, vase, aromatherapy, pen holder, pen holder, printing box, glasses case, glasses frame, and even the bracelets and fans used by the singers. The toner cartridges, etc., are all used by the makers. Although the gongs are easy to see, in the museum, you can still see the combs and other items used by the Empress Dowager Cixi in the Qing Dynasty and the 玳瑁 peach blossom fans left by Dong Xiaowan in the late Ming and early Qing dynasties. They are all exquisite, rare treasures, and the Forbidden City. There are also some handicrafts crafted in the museum.

In the West, 玳瑁 was used by ancient Greeks and Romans to make jewels such as combs, brushes and rings, and ancient Egyptians, ancient Greeks and ancient Romans put enamel on furniture. Many exquisite urns have been found in the ancient tombs of the Han Dynasty and the Egyptian tombs of the Nubian rule. In Japan, only the shells of the various turtles are used by the Japanese to make jewelry, so in Japanese, the shell is called "armor".

Identification of cockroaches

Look at the color: 玳瑁 yellow-brown, translucent, soft, soft, bright, warm; imaginary 玳瑁 is made of chemical materials such as celluloid, bakelite, resin, etc., its color is less than the real product, lack of moisture The bright and warm feeling seems to be dry; the fake cockroaches pretending with the horns are not as bright as the brilliance, and there are no red and black transparent yellow spots, which are prone to cracks in the layers during use.

Look at the markings: The inside of the real scales has a variety of dark brown markings. These markings are gathered by countless dots of different sizes. The denser the dots, the deeper the color, the clearer, more beautiful and transparent, especially the shade. The change of smudges and the natural interest; the markings of the imitation goods are often brownish red, and the boundary between the translucent background and the translucent background is blurred, not as the markings of the real product are clearly distinguishable, and the markings are flat and stagnate, no shading changes and halos color.

Distinguish the odor: scrape some powder from the bottom or inconspicuous part of the product. Use fire or hot needle to touch it. The true cockroach will not solidify and give off the smell of burnt hair. The imitation is different, and the bakelite gives off a sour smell. Celluloid is a camphor smell, and casein plastic gives off a vinegar flavor.

Observing the light transmission effect: under the illumination of the strong light or the light-collecting tube, the blood-grain pattern of the true product is silky and penetrates into the inside of the nail piece; the blood-texture of the imitation product is in the form of a sheet or a mass, which is located on the surface of the nail piece. . In addition, under the ultraviolet light, the yellow and transparent parts will emit a slight blue fluorescence, but the imitation does not.

Observe the water condition: 玳瑁The real thing has the function of “water escaping”. When it is taken out from the water, the water will spread out around; the imitation will not happen.

Jujutsu Kaisen

Yuji Itadori is an unnaturally fit high school student living in Sendai with his grandfather. He regularly avoids the track team due to the time commitment required for it, despite his innate talent for the sport. Instead, he chooses to join the Occult Research Club; due to the freedom it allows him in attending, he goes to visit his dying grandfather in the hospital every day. On his deathbed, his grandfather instills two powerful messages within Yuji: "always help people" and "die surrounded by people". These two ideas seemingly stem from his grandfather's own regrets. After his grandfather's death, Yuji interprets these messages as one statement: everyone deserves "a proper death". He is then confronted by Megumi Fushiguro, a sorcerer who informs him of a high-grade cursed charm talisman at his school that Yuji recently made contact with. His friends at the Occult Club unsealed the talisman, a rotting finger, which attracted Curses to the school, creatures that are brought about through negative emotions and are strengthened by consuming magical powers present in sorcerers or such charms. Unable to defeat the Curses due to his lack of magical powers, Yuji swallows the finger to protect Megumi and his friends and becomes the host of Ryomen Sukuna, a powerful Curse. Due to Sukuna's evil nature, all sorcerers are required to exorcise him (and by extension, Yuji) immediately. However, despite being possessed, Yuji is still able to retain control over his body for the most part. Seeing this, Satoru Gojo, Megumi's teacher, decides to take him to the Tokyo Prefectural Jujutsu High School to propose a plan to his superiors: postpone Yuji's death sentence until he consumes all of Sukuna's fingers, allowing them to kill Sukuna once and for all.
