Defectos por secado
Ease of Drying: It takes about 4 months to air dry boards 15 mm thick. Drying Defects: Wood from this species is difficult to kiln dry as it is prone to deform. Kiln Schedules: For kiln drying, a temperature of 40.5 to 65.5 degrees is recommended with corresponding relative humidity of 85% to 40%. A mild kiln schedule is recommended, drying the wood in about 7 days from green to 1% moisture content.
