A method for manufacturing a modified wood prepares a natural wood material containing more than a predetermined amount of a solvent for dissolving two different compounds which chemically react with each other to form an insoluble compound, provides a layer of each of the different compounds inside each of two opposing surfaces of the wood material, causes the different compounds to chemically react with each other within the wood material and fixes the formed insoluble compound in the wood material, whereby the fixation amount of the insoluble compound in the wood can be effectively increased.

Method for manufacturing modified wood

A method of manufacturing a modifed wood material can fix within a raw wood material an insoluble, non-flammable inorganic compound with a highly efficient reaction achieved between cations and anions by sequentially immersing the raw wood material at least three times alternately in each of, and different one from that employed immediately before of a first water-soluble inorganic substance solution containing cations and a second water-soluble inorganic substance solution containing anions.
