The multilayer foaming glass product is composed of the base foamed glass layer including a heat resisting metallic wire, the intermediate color foamed glass including an inorganic pigment and the transparent glass layer. The specific gravities of glass layers are 0.7-0.9, 1.0-1.8, 2.5 g/cm3 respectively, and the used metallic wire comprises 18-20 wt% chromium and 8-10 wt% nickel alloy. The multilayer foaming glass product is manufactured by (a) mixing 0.3-0.5 wt% calcium carbonate, 2.0-5.0 wt% a binder, 1.0-5.0 wt% metallic wire and glass powder for the base layer, (b) mixing the foaming composition with 3mm granular particles and 0.2-0.3 wt% calcium carbonate, 1.0-3.0 wt% a binder, 2-5 wt% a sintering agent, 0.2-0.5 the inorganic pigment and glass powder for the intermediate layer, (c) filling each layer composition and the transparent glass composition powders, (d) heating and foaming the mixed layers.
