Asian pear refers not to a single type of wood, but to a general term for a class of wood. The wood of the genus Pterocarpus is divided into three categories: rosewood, rosewood, and Asian rosewood. Rosewood and rosewood belong to the category of redwood national standard, while Asian pear is not.
There are 30 kinds of wood in the red sandalwood, and there is only one kind of wood of rosewood, namely sandalwood rosewood. There are seven kinds of wood in rosewood. These seven kinds of wood are: Andaman rosewood, Hedgehog rosewood, Vietnamese rosewood, Indian rosewood, bird foot rosewood, sacred rosewood, large fruit rosewood. There are more than twenty kinds of Asian rosewood. The properties of these more than 20 kinds of wood are close to that of rosewood, but they cannot fully meet the standards required by the national standard for rosewood in terms of density, so they are called "Asian pears".
At present, the Asian rosewoods appearing in the Chinese market mainly include African red sandalwood and Angora purple. These two kinds of wood are classified into the Asian rosewood because of the large diameter of the tube hole and the relatively small density. In the market, it is also called "grass pear".
The following are the basic identification features of these two kinds of "Asian pears", which are briefly introduced for consumers to refer to when purchasing furniture.
