A method of bonding a first, vitreous sheet to a second sheet to form a laminate which includes the steps of bonding together the sheets using an adhesive material which is at most 250 mu m thick and has a viscosity in the range 15 to 300 poises, the adhesive being such that it is settable by evaporation of solvent or by hot or cold curing. The assembly is degassed by subjecting it to sub-atmospheric pressure at a temperature such as to maintain the adhesive viscosity within that range whereafter it is exposed to atmospheric pressure and the adhesive is caused or allowed to set. |
