Note: Asian pear that is not a single timber, but a general term for a class of timber. Pterocarpus timber is divided into three categories: red sandalwood, rosewood class, there is the Asian rosewood class.

recent years as people appreciate the level and quality of life improvement, classical furniture began to become people's attention. Since last year, China's high-grade hardwood material prices shot up so that everyone dumbfounded.
2006 sandalwood red sandalwood market price in the second half is about 120,000 yuan per ton, to October 2007 shot up to 65.7 million yuan / ton. Brazil pear wood in a relatively similar price, high quality edge to become a new bright spot in the market.

After the string in the paint decorated surface or near the surface of wood rays obvious strings, string section wood ray markings are clear. Gives a quiet, soft feel. Room furniture and paper can do all devices.
the physical properties of wood: air-dry density of about 0.80-0.86g/cm3, wood with a gloss,easy indian recipes, no special smell and taste, texture oblique to the staggered structure thin and uniform. Timber weight, high strength. Few termites. structural characteristics of the wood
: diffuse porous wood. Obvious difference between heartwood and sapwood, yellowish brown to reddish-brown heartwood, sapwood white to pale yellow white. Growth rings indistinct. Pores under a magnifying glass clear, slightly smaller to medium alone, and a few short tracks out complex pores (24), the pore often with dark sediment, loose. Axial parenchyma under a magnifying glass clear, the main pipe for the waterfront, wing shape, wing-shaped and round circles poly shape. Wood-ray non-overlapping Health, under a magnifying glass clear, medium to slightly dense,south indian cooking, and even fine to just fine. Grain straight, often staggered, fine structure, uniform shrinkage of the great, good nail holding power, dry and slightly faster, easy to crack, warp. Evaluation pear better than Myanmar.
Recently, the raw material exporting country itself, protection of natural resources under international community pressure, limiting logging and exports. According to the United Nations reported that the material provides a large number of environmental funds to Madagascar, to subsidize the ban on logging policy, from early 2005 to implement the restrictions on timber exports Myanmar policy. July 2006 Laos has banned black wood red wood timber exports. In early 2006, Brazil made a log export ban policy on the export profile also made more stringent restrictions on the thickness of 10cm width 60cm. The introduction of export policy, has undoubtedly become more scarce wood Jingui.
the kind of wood as early as the early Republic of China have used classical furniture with it has been five or six years old. More important is the pear and Brazilian rosewood some properties similar to, but the price is relatively low, naturally became the new darling of some white-collar workers, those who favor more and more.
