Excerpt from Creosotes and Creosoting: A Discussion of Oils and Methods From a Practical Viewpoint, With Some Examples From Experience of Difficulties Encountered in Obtaining Satisfactory Results

The actual operation of. Injecting the creosote is divided into three parts the steaming of the timber to dissolve and evaporate the contents of the wood cells; the application of a vacuum to empty the wood cells by draw ing off the sap and resinous substances, and the injection of the creosote under pressure.

For light treatments air seasoning or hot-air seasoning may be substituted for the steaming process, but in general for a treatment of 14 pounds per cubic foot or more the timber is steamed. Besides facilitating the removal of the contents of the wood cells, the steaming, if carried far enough to raise the temperature of the timber throughout above 1000 C., sterilizes itand prevents absolutely any deterioration of the timber by rot as long as the outside cells are filled by the antiseptic oil.
