Abstract : Various factors must be considered if good results are to be obtained by seasoning. Among these are the size of the lumber to be dried, the use of end coatings to retard end drying, proper piling, and other practices. Above all, thorough seasoning is essential. If wood is not at a uniform moisture content throughout at the time of fabrication, subsequent machining may expose surfaces of unequal moisture content. Surfaces with a high moisture content, when exposed to a drying atmosphere of low relative humidity, will begin to lose moisture rapidly. As a results, unequal drying stresses will develop, and further checking or warping may occur. This may be overcome by coating the article with a moisture resistant coating, and storing in a cool room until thoroughly dry. The best solution, however is to allow the wood to season to a uniform moisture content throughout before fabrication is attempted.
