Book excerpt: Poles of white spruce, Sitka spruce, mountain hemlock, and balsam poplar were subjected to several variations on a standard preservative process: Allowing the material to partially season before treatment; incising the material when green or partially seasoned; and elevating the temperature of first solution of copper sulfate and letting the wood cool before transfer to second solution of sodium arsenate. Double diffusion, retention and pentration were related to service life.

This book was released on 1976 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several hardwood species have proven difficult to treat with wood preservatives, by either pressure or double-diffusion processes. Conventional double-diffusion methods have generally not worked as well with hardwoods as with softwoods. Modified double-diffusion methods, though, have proven useful in treating such species as Engelmann spruce, Rocky Mountain Douglas-fir, and several Alaskan species. These softwoods have been difficult to treat even by pressure. If successful, modified double-diffusion treatment of hardwoods could offer alternatives to pressure treatment, thermal treatment, and cold soaking for many species, and possibly offer better treatment for certain species. Most of the previous work using conventional double-diffusion with hardwoods used posts or material in the round form. This study has explored the feasibility of treating sawn hardwood stock with double-diffusion methods. Penetrations were observed by use of a chemical stain and retentions were determined by the assay of various zones. The data obtained provided guidelines for recommending treatment schedules.
