The Effect of Organic Liquids on Collapse and Shrinkage of Wood. II. Effect of Drying Temperature

The effect of drying temperatures from 110? to 276?F., on the collapse and shrinkage of black oak and madrone samples in which the water had been replaced with either cellosolve or n-propyl alcohol was determined. It was found that, although collapse of the green control specimens tended to increase with drying temperature, particularly in the radial direction (thickness), the collapse of treated specimens was only slightly affected by temperature. Treated specimens showed an increase in shrinkage after steam distillation and redrying which was generally greater for specimens originally dried at the lowest temperatures.
