Technological Characteristics
| Physical properties | |
|---|---|
| Green density (g/cm³) | 1.30 |
| Air-dry density at 12% (g/cm³) | 0.97 |
| Basic specific gravity | 0.80 |
| Total tangential shrinkage (%) | 8.2 |
| Total radial shrinkage (%) | 7.5 |
| Total volumetric shrinkage (%) | 15.0 |
Processing
| Sawing | power required |
|---|---|
| Blunting effect | moderate to high |
| Drying | very slow {nir-sensoning is recommended prior to kilndrying) U.S. kiln schedule T2-C2 for 25-38 mm (4/4 to 6/4) stock and T2-Cl for 50 mm (8/4) stock or British schedule B (25 mm) risks of distortion; slight risks of checking; possible, marked tendency to check and end split |
| Machining | difficult due to hardness; necessary to maintain sharp tools; the fine dust may cause allergy |
| Glueing | special precautions needed |
| Nailing | pre-boring necessary |
| Finishing | good |
| Veneering | possible to slice |
