PROBLEM TO BE SOLVED: To provide a method of manufacturing crystalline molten slag, in which dense and fine crystals can be grown to have sufficient mechanical strength to apply for aggregate or the like. SOLUTION: In a melting step for forming an incineration ash molten material by charging garbage incineration ash into a melting furnace and heating and melting, its composition is adjusted so that the basicity of the crystalline molten slag is 0.8-1.3 and TiO<SB>2</SB>is contained in amount of 2-10 mass%. The incineration ash molten material is cooled by air to obtain the crystalline molten slag. COPYRIGHT: (C)2008,JPO&INPIT
