According to the productivity of the Ming Dynasty was able to cut sandalwood tree is not native left, was a miracle! China is indeed in some places to some species that red sandalwood, red sandalwood of China in the end produced what is not known. \

real number of the rare luxury of rosewood, mahogany is from a relatively large volume of production of the Dalbergia species, Dalbergia Dalbergia, the world's approximately 120 species, with trees and shrubs of about 25 species in China, the Huaihe River south of the wide distribution of trees for the good material. Press material can be divided into heartwood and sapwood color clear and obvious two categories, with obvious heart sapwood with heartwood red, beautiful patterns, materials and better, is a valuable timber, civil and commercial as mahogany, high commercial value. This is not obvious who heartwood and sapwood of wood, the heartwood yellow-white, non-beautiful patterns, poor corrosion resistance, low commercial value, the vast majority of our distribution of such material.
This is a mahogany name

messy, not pan-valuable wood, yellow rosewood and ebonylike wood (Dalbergia Guangdong imported mahogany with this term) are in this case, rare African Ebony D.melanoxylon, 1.20g / cm3, wood color depth close to Mexico, also from this case. My Rosewood class, there are two: First, the black Xishuangbanna Dalbergia D.fasca, 0.99g/cm3, the Government of the species found in 1968 arrival in North America, and in Shanghai trial. Second, Hainan Island Dalbergia odorifera D.odorifera ,0.818-0 .94g/cm3, brown or light brown sapwood, the heartwood is small, reddish-brown with black stripes, a pungent aroma, but also for the system of Buddhist raw materials, antique world should have said is it yellow rosewood. \50 years old, a small number of tree diameter at breast height up to 45cm.

can be seen from the above

, whether or Dalbergia rosewood timber, the quality differences are large, and some red sandalwood is nowhere near as comprehensive quality wood Dalbergia. Wood is a few really good, so some of them a powerhouse in the red sandalwood, pear, etc. stand out individually addressed.


mahogany is not difficult to identify, according to the severity of wood, color, light and dark patterns determine whether the quality pretty close, and to identify what species a kind of timber in the end? it is difficult for another difficult . Specifically: pattern, texture and color is the soul of wood, some of Southeast Asia, although the heavy trees and foliage, the intensity is high, but the door is a common characteristic rough texture, no pleasing patterns, there is no decorative value, high commercial value are not up.


Dalbergia rosewood and mahogany red sandalwood is not easy to distinguish, the most convenient way, using wood chips placed in a glass bubble, red sandalwood is often grayish green. Produce the phenomenon of so-called fluorescence, Dalbergia rosewood is little fluorescence phenomenon.
