The multi-layer foamed glass is mfd. by (a) mixing 100 wt. pts. of soda lime glass-crushed material with 0.3-0.4 wt. pts. of calcium carbonate and 3.0-5.0 wt. pts. of water glass to obtain a granular base foamed layer (A), (b) mixing 100 wt. pts. of soda lime glass with 0.2-0.3 wt. pt of calcium carbonate, 0.5-2.0 wt. pts. of inorganic pigment, 1.0-2.5 wt. pts. of clay and alumina and 3.0-4.0 wt. pts. of water glass to obtain a granular color foamed layer (B), (b) laminating layers (A,B) and a glassy coated layer (C) in the guide mold, and press-molding the laminated layers, and (c) melt-foaming them. The glass is used for a building material.
