Abstract
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.
