A method for producing products for treating wood and other cellulose produc ts to improve the flame retardancy, and the insecticidal and fungicidal properties of the products. A calcium borate ore, such as colemanite, is reacted first with an acid such as acetic acid. The reaction products, including calcium in solution, are then treated with ammonia, producing ammonium pentaborate. The resulting composition is applied to the wood or other cellulose products by methods such as pressure, diffusion, or immersio n and/or dipping treatment. The products have superior leach resistance to wat er when compared to conventional treatment compounds.
