Abstract

139,974. Lambert, A. June 11, 1919. Wood, treating with liquids.-A process for hardening soft wood, preserving it against attack by vermin, and fire-proofing it consists in impregnating the wood with a solution of metallic salts, such as an ammoniacal solution of copper and zinc salts, mixed with borax, potassium chromate, and cement powder, with or without a small proportion of salicylic acid and sodium fluoride. A suitable impregnating mixture comprises 4 to 6 parts by weight of copper salts and 2 to 4 parts of zinc salts dissolved in strong ammonia, 2 to 3 parts of borax, and 1 to 2 parts of potassium chromate dissolved in 10 to 20 parts of water, and 5 to 10 parts of Portland or like cement.
