PURPOSE:To manufacture the titled glass plate in high productivity with generation of bubbles, by laminating a pair of glass plates interposing plural sodium silicate layers therebetween. CONSTITUTION:A solution obtained by adding glycerol to sodium silicate of No.3 or No.4 (JIS) is applied to the surface of a glass plate with a curtain flow coater to a thickness of 0.05-0.5mm., and dried at <=100 deg.C for 1-30min. The coating and drying are repeated several times until the thickness of the sodium silicate layer reaches about 0.2-5mm.. Another glass plate is placed on the sodium silicate layer, and the laminate is firmly integrated by heating under pressure in an autoclave.
