What kind of wood is the dark wood that sinks when placed in water?

Black wood is a type of wood that sinks when placed in water.

Blackwood. A type of wood with a hard, dense head that sinks when placed in water. They are generally carved into works of art, and on the outside they look as if they were painted with black lacquer, dark and shiny, and a piece of black wood carving is not easy to come by.

The dark wood tree looks like a shrub, with leaves as large as fingernails, thin branches with 2 cm long thorns, and its branches are prone to forking, so it is difficult to grow into a towering tree. Without artificial pruning, the Blackwood tree will grow a lot of twigs from the ground. The so-called black wood is the core of the tree, and only branches with a diameter of 20 centimeters can form a black core with a diameter of about 10 centimeters, and thin branches have no black wood at all.

The black wood stem is not black, and generally the branches with a diameter of 10 cm do not have black wood, and only the branches that have grown for three to five years will have black wood, so when you see a black wood product with a thick arm, it is actually sawn down from a very thick tree. Black wood is not beautiful, before processing, black wood and ordinary wood are the same, only from the section can see that the middle is a black core, processing black wood, is to peel off the outside, cut into sections, carve the inside of the black core. Black wood carvings are troublesome to process, and the carvings here are often whole wood carvings.

Dear, I'm glad to answer for you: Is the wood that sinks to the bottom of the water all good wood? A: No, wood that can sink is not necessarily good wood.

Because whether the wood sinks or not is determined by the density, not whether the wood is good or bad. Wood that is denser than water will sink to the bottom, such as rosewood

It is produced in India, the Philippines, Guangdong, the Malay Peninsula and Thailand. Submerged wood is dense and hard wood, wood is divided into softwood and hardwood, hardwood is better than softwood, but not all hardwoods will sink. Only hardwoods with high hardness and density will sink.

Wood is a lignified tissue formed by plants that can grow secondarily, such as trees and shrubs. After the end of primary growth in these plants, the vascular cambium in the rhizome begins to move, developing bast outward.

Red sandalwood, red sandalwood, wenge, sour branch, etc.

An object immersed in a liquid is subjected to the vertical downward gravity and the vertical upward buoyancy force, and when the gravity is greater than the buoyant force, the object sinks; When gravity is less than buoyancy, the object floats; When gravity is equal to buoyancy, the object is suspended in the liquid.

For a solid object, immersion in the liquid, if the density of the object is greater than that of the liquid, the object sinks; If the density of the object is less than that of the liquid, the object floats; If the density of the object is equal, the object is suspended in the liquid.

Water sinking wood belongs to the sinking wood, it can also be called gloomy wood, this wood texture is very hard, not afraid of insects, will not corrode, is a very precious high wood, it is buried under the riverbed for several years after geological disasters to form, it will not float on the surface in the water, and can keep the water clear.

Indonesian ebony, its wood has an air-dry density, the specific gravity is greater than water, and it can sink in water.

Lightning strikes jujube wood, lightning treatment changes the internal composition and density of jujube wood, and the density is greater than that of water, so it can sink in water.

Its wood Daqing is hard, the specific gravity is very large, and it cannot float in the Qifang Qishui, but it sinks to the bottom like a stone.
