Abstract: Red oak, soft maple, cherry, pecan, sweetgum, basswood, aspen, white oak, elm, hackberry, black ash, and bur oak were kiln-dried by normal-temperature (180°F maximum) and high-temperature (230°F) schedules. Degrade from warp after drying at normal temperature was compared with degrade from drying at high temperatures. Only the oaks and several boards of "wet pocket" sweetgum and aspen that were green from the saw did not dry successfully at high temperatures—they had a greater amount of honeycomb or warp than the conventionally dried material. However, these species did dry satisfactorily at high temperatures if their average MC was reduced to below 25 percent by air-drying or below 20 percent by normal-temperature kiln-drying.
