The invention relates to the preparation of hydrated alkaline silicate compositions for making intumescent layers for fireproof glazing, said compositions being such that, when applied between glass sheets, they form a solid gel without drying, wherein the compositions are obtained from a stable and fluid solution subjected to partial dehydration at a limited temperature and under a reduced pressure for a duration shorter than that required for the mass curing of the final composition. |
