Cross section: Heart sapwood has obvious difference. The heartwood is black or dark brown. The sapwood is nearly white. The growth ring was not obvious.
Macro-structure: loose-porous materials. Under the tube-hole magnifier, it is slightly less and smaller; it is mainly single tube-hole and a few diameter-row compound tube-holes (2-3); it contains dark gum. Axial parenchyma is obvious and well developed under magnifying glass. It is stringed in chord direction and arranged evenly. It often forms a network with wood rays. It is slightly dense and narrow under a wood-ray magnifying glass.
Wood properties: slightly glossy; interlaced texture; very fine structure; very hard; high strength; very dry shrinkage. It is difficult to process, contains silica, easy to blunt cutter and smooth cut surface. Good adhesion and polishing. Nails must be punched first. It's very resistant to decay. Drying slowly, easy to crack. Sawdust is irritating to the skin and throat. The air-dry density is 1.01g/cm3.
Heartwood is dark brown to yellowish purple brown, some nearly black or often with black stripes. Log pole shape is poor, the end surface is irregular, rarely round or elliptical. There are many holes, and the yield is very low, about 10 to 15 percent.
