Abstract
The present invention provides a process for the treatment of wood material impregnated with an aqueous ammoniacal solution of water-insoluble treating chemical and having deposits of treating chemical on its surface. The process comprises submerging the impregnated wood material in the ammoniacal solution, separating the wood material from the solution and maintaining it in a moist, ammoniacal atmosphere until the wood surface is substantially free of liquid. In another aspect, this invention relates to a process for producing wood material treated with the ammoniacal solution, where the product has a clean surface.
