What is air seasoning?
Air or Natural seasoning this process takes rather a long time,approximately one year for every 25 mm of timber thickness but it is effective. The floor of the shelter is rested on concrete or brick pillars, and the area underneath the floor is hard cored to discourage insects and fungi which would have detrimental effect on the timber being seasoning.The traditional method of seasoning timber was to stack it in air and let the heat of the atmosphere and the natural air movement around the stacked timber remove the moisture. The process has undergone a number of refinements over the years that have made it more efficient and reduced the quantity of wood that was damaged by drying too quickly near the ends in air seasoning.Moisture loss from the side of the wood is at about the right rate not to cause collapse of the cells, but near the ends of the wood, the moisture loss can prove to be too fast. Often the ends are wrapped or painted to slow the moisture loss from the end grain.
