Abstract
A study was conducted to measure how the color in rubberwood boards developed under standard kiln drying schedule. Edge-matched rubberwood boards were dried at 20, 40, 60 and 80 % of the drying time to achieve the final moisture content of 12 ± 2 %. Discoloration increased with higher temperature and drying time, while lower relative humidity tended to minimize discoloration. It is recommended that lower drying temperature and relative humidity schedules are used to minimize discoloration of rubberwood during drying.
