Air-drying timber stack. Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood: Woodworking
Because of the composition of wood, careful control of humidity is a factor in preventive conservation. If the relative humidity is too low the wood will release some of its moisture into the air and dry out. Conversely, if the relative humidity is too high, the wood absorbs water from the air and expands.
Green wood is considered to have 100% moisture content relative to air-dried or seasoned wood, which is considered to be 20%. Energy density charts for wood fuels tend to use air dried wood as their reference, thus oven dried or 0% moisture content can reflect 103.4% energy content.
Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. .

These processes autoclave the treated wood, subjecting it to pressure and heat, along with nitrogen or water vapour to control drying in a staged treatment process ranging from 24 to 48 hours at temperatures of 180 °C to 230 °C depending on timber species. These processes increase the durability, dimensional stability and hardness of the ...
