Abstract: A process and product for increasing the flame resistance and thermal insulation properties of chemically treated substances, in some cases providing the treated substance with flame resistance at temperatures higher than 1800° C. (direct fire), with no limit to the time of exposure. A number of embodiments of flame resistant compositions are discussed herein but all embodiments include a mixture containing water, inorganic acids, ammonium salts, sodium carbonate and pyrophosphate and, in some instances other constituents. The disclosed process treats substances to prevent the generation of any flames. The substances that have successfully been tested with the disclosed process include cloth (natural and synthetic), rugs and carpets, wood, cardboard, and paper. However, it is believed that this process can be applied to an unlimited number of flammable cellulose substances.
