PROBLEM TO BE SOLVED: To provide a manufacturing process capable of continuously and inexpensively giving foamed glass having a surface formed into zeolite which is effective as embedding material, a soil conditioner or marine covering sand material. SOLUTION: The foamed glass having the surface formed into zeolite is manufactured by heating and melting a raw material obtained by mixing powdery glass with a foaming agent, lowering the temperature to a temperature near the glass softening temperature to keep the foamed state and applying an aluminum salt aqueous solution to react and cool.
