What is meant by kiln seasoning of wood?
The process of kiln drying.seasoning consists basically of introducing heat. This may be directly, using natural gas and/or electricity or indirectly, through steam-heated heat exchangers, although solar energy is also possible. In the process, deliberate control of temperature, relative humidity and air circulation is provided to give conditions at various stages (moisture contents or times) of drying the timber to achieve effective drying. For this purpose, the timber is stacked in chambers, called wood drying kilns, which are fitted with equipment for manipulation and control of the temperature and the relative humidity of the drying air and its circulation rate through the timber stack (Walker et al., 1993; Desch and Dinwoodie, 1996).
This form of seasoning/drying provides a means of overcoming the limitations imposed by erratic weather conditions. In kiln seasoning as in air drying, unsaturated air is used as the drying medium. Almost all commercial timbers of the world are dried in industrial kilns.

As fresh timber which is obtained from trees contains about 30 to 40 % sap or moisture. This sap is very harmful for the life of a timber.

Seasoning of wood from my experience is when wood is cut and stacked or stored to be used in the future, for example the following winter. The wood seasons as it sits, the longer the better. Season meaning "ages" which allows the wood to dry out and the natural chemicals and oils in a tree to become more susceptible to flame which allows it to burn better and hotter
Like many words in English, seasoning can mean different things. It can apply generally to the different herbs and spices that we put in food, and it can refer to an aging process. Seasoned wood means wood that has aged, probably out of doors, for some length of time. This means that it is a stronger and more stable building material. It has done most of the drying and shrinking that it will do. On…
Kiln dried Pine will be much lighter and show no signs of any sap or sap leakage. Sometimes will have a more "whitish" tint to the wood, not as yellow as non kiln dried, but that is not always the case. Some studs will actually be stamped as so.
