Part of a melt vessel is formed from a porous member which is permeable to gas and impermeable to melts. Alternatively, a bottomed cylindrical partitioning member immersed in a melt in the melt vessel, or part of a circulating vessel through which the melt circulates, or a dam disposed in the course of circulation of the melt in the melt circulating vessel is formed from the porous member. Vacuum pump is used to suck gas from the melt or gas produced by a reaction at the interface between the melt and the porous member through the porous member, to the side of that surface of the porous member which is not in contact with the melt and kept at a vacuum or at reduced pressure. Then, the pressure at the interface between the melt and the porous member is lowered, and a space which is in a vacuum or at reduced pressure can be easily created in the melt. Thus, solute ingredients of the melt nucleate easily to form gaseous substances, so that the gaseous substances are sucked into said space and removed from the melt.
