In a process of manufacturing discrete, ceramic fiber insulation products, the steps of: (a) providing an alkali-stabilized water suspension of colloidal silica; (b) incorporating a water-soluble salt of an inorganic oxygen-containing acid in said suspension to form a modified suspension; (c) and either infusing said modified suspension into a pre-treated mat of alumino silicate fibers or infusing the alkali stabilized water suspension of colloidal silica into the pre-treated mat and then subjecting the thus-treated mat to an acidic gas; and then, (d) drying said mats.
