C. for more than 24 hours, they form a mixture which is capable of flow, and on heating to temperatures above 45.degree. C. they change into a transparent gel in less than 24 hours. In addition to other uses, such fireproofing gels are particularly suitable for the production of laminated glass constructions having a-fire protection action.
