In the article "Redwood Furniture and Solid Wood Flooring" by Mr. Yang Jiaxuan, the distinction between rosewood and black red rosewood was introduced in detail .
Â
The first is the difference in weight. The rosewood wood of the genus Pterocarpus is light and soft, mostly floating in water, and the air-drying of 7 kinds of rosewood ( Chongqing rosewood, Andaman rosewood, Hedgehog rosewood, Indian rosewood, big fruit rosewood, sacred rosewood, bird foot rosewood ) density of 0.53-1.01 grams per cubic centimeter (average 0.79-0.91 grams per cubic centimeter); red rosewood multi-submerged in water, 7 rosewood wood (Barry rosewood, rosewood state tournament, Cochin rosewood, fluff rosewood, Central America rosewood, Albright, Dalbergia slightly concave) of air-dry density of 0.90-1.22 grams per cubic centimeter (an average of 1.02 - 1.14 grams per cubic centimeter). Black rosewood also sinks in water, 8 kinds of black rosewood ( knife-shaped black rosewood, black rosewood, broad-leaved rosewood, Lushi black rosewood, East African black rosewood, Brazilian black rosewood, Amazon yellow Tan, Belize Dalbergia has a dry density of 0.82-1.33 grams per cubic centimeter ( average 0.92-1.06 grams per cubic centimeter ) .
Â
The second is the fluorescence phenomenon of wood dust leaching solution. Wood shavings water infusion, rosewood has more fluorescence ( birds and red sandalwood is the most significant ) , while red rosewood and black rosewood are not.
Â
The third is the smell. Rosewood wood has a spicy aroma, while red and black rosewoods have a strong acidity.
Â
The fourth is that rosewood wood has many tendency to diffuse to semi-disperse or ring-hole material, while red-black acid is a loose-pore material, and semi-annular holes are invisible.
Â
The fifth is that the rosewood color is reddish brown to purple red, relatively uniform, the ray tissue is homomorphic, and there is no tendency for the ray tissue to be organized, usually in a single row. Red black rosewood wood color red brown to purple red or black, relatively uniform, often mixed with dark stripes, the ray tissue is usually homomorphic, the shape is obvious, usually 2 columns, less single-ray.
