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
Furniture oils are not recommended for maintenance as many of them contain linseed oil or other drying oils, and when used repeatedly will create a gummy, insoluble surface coating that darkens and obscures the grain of the wood. Other furniture polishes contain non-drying oils such as lemon oil, but attract and entrap dirt and grime.
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.
Wood contains an abundance of chemical groups called free hydroxyls. Free hydroxyl groups readily absorb and release water according to changes in the climatic conditions to which they are exposed. This is the main reason why wood's dimensional stability is impacted by swelling and shrinking.
Furniture preservation is the practice of maintaining the condition of furniture, especially antique or valuable wooden furniture. One of the most significant dangers to wooden furniture is humidity ; wood will tend to expand by absorbing water from the air when it is humid, and shrink when the air is drier. [ 1 ]

Wood warping costs the wood industry in the U.S. millions of dollars per year. [citation needed] Straight wood boards that leave a cutting facility sometimes arrive at the store yard warped. Although wood warping has been studied for years, the warping control model for manufacturing composite wood hasn't been updated for about 40 years ...
