Title: Effect of Oven Heating and Hot Pressing on Strength Properties of Wood

Abstract: There are various commercial operations and service conditions under which wood is heated that will have much the same effect on the strength properties of the material as heating in an oven. For example, it is common practice to dry veneer in mechanical dryers in which relatively high temperatures are used. Fairly high temperatures are also employed in wood laminating. Wood may be similarly heated in hot air ducts, in dry kilns, roof timbers over boilers and furnaces, in floors under ovens, dryers, and steam traps, and under or near steam pipes or radiators. Under some of these service conditions, the wood may be exposed when there is more or less humidity that may accelerate the rate of strength loss to a variable extent. Increasing the humidity of air in which wood is heated increases the effect of hydrolysis, depending on the amount of moisture present, the temperature, and the time the temperature is applied. Wood heated in the oven where it is soon ovendried will naturally have the strength affected the least.
