A flame retardant or fire retardant preparation can be employed with fibrous material containing either cellulosic fibers, non-absorbent fibers, or blends thereof. The preparation is formed of an aqueous solution of ammonium sulfate, a metasilicate salt serving as binder, and ammonium phosphate (MAP or DAP). An ultraviolet inhibitor is preferably included in the solution. A wetting agent promotes penetration of the solution into cellulosic fibers. An ultraviolet fluorescent agent permits non-destructive testing of articles after treatment. For increased sensitivity, the preferred fluorescent agent is a substituted 2,2' disulfonic acid sodium salt.
