Red sandalwood is a precious wood, mainly produced in the Nanyang Archipelago in the tropical region. There are also a few growing in Guangdong, Guangxi and Yunnan in China. Its wood is hard and heavy, and it sinks in water immediately. No scars, purple and black. "Natural History" says "The new one is red, the old one is purple, and there are crab claw patterns, the new one is soaked in water, and it can be dyed." From the actual furniture photos in the color picture, it can be seen that its texture is dense After waxing and polishing and air oxidation, it gradually evolved into red purple and black purple. The tone is deep and steady, with a quaint and quiet feeling. This is the most important feature of rosewood furniture. The use of purple to make artifacts has a long history, and it has been recorded in the early years of the Eastern Han Dynasty. In the Ming Dynasty, rosewood was favored by the royal family. Officials from the Ming Dynasty regularly dispatched them to Nanyang to purchase, and the royal family stored a lot of red sandalwood. Until the early Qing Dynasty, the palace made furniture, mostly using the Ming Dynasty inventory. In the Qing Dynasty, red sandalwood was regarded as the most valuable wood, but after the mid-Qing period, the inventory was exhausted, the supply was interrupted, and the red sandalwood was in short supply. Therefore, the furniture after the mid-Qing Dynasty was replaced by mahogany. Rosewood is produced in Guangdong and Guangxi, but the number is not large. "The Museum of Natural History" says: "The rosewood produces Jiao (Jiaozhi) Guang (Guangdong, Guangxi) Xidong, a flowering palm tree with leaves like pears but no flowers, The wood color is red and purple, and the texture is delicate. It can be used as utensils, tables, chairs, and study rooms. "" Guangzhou Zhi "records:" The flower palm color is purple red, slightly fragrant, and its patterns have ghost faces, also known as raccoon spots, also known as 'Flower raccoon'. The old pattern is fisted, the tender pattern is straight, and its knots are round like money, and those with the wrong size are better. " Rosewood is divided into new and old pears. Laohua pear, also known as Huanghua pear, is of moderate material, warm and non-deformed, with aroma, orange-yellow color, red-purple color, and dark and dark patterns like tanuki. Most of the high-end and elaborate furniture of the Ming Dynasty was made of Huanghuali. Due to the beautiful texture of the old rosewood, the craftsmen mostly use the whole body and smooth treatment, without carving, to highlight the natural beauty of the wood texture, and the rosewood furniture is gorgeous. Xinhua pear, also known as Caohua pear, has a reddish yellow color, loose wood, thick brown eyes, stripes, and no luster. The material is far inferior to old Huali. Black wood Also known as Qizi wood and chicken wing wood, it is also a valuable wood produced in Xifan. This wood is also produced in Guangdong and Hainan. This kind of wood is hard. Suzhou artisans say that "there is sand in the wood". When the material is broken, it is often sawed, so it is also called "sand stone wood". The texture and tone of the wenge wood is special, and it changes under the influence of light, ranging from dark red to heavier purple brown. This may be what Beijing craftsmen call the difference between old and new. The new wood is rough, purple and black, and the texture is unclear; the old texture is delicate, with purple and brown shades, and shiny, as beautiful as the feathers of the blackbird. There is not much chicken wing wood, so there is less furniture handed down. Product Features
