<P>PROBLEM TO BE SOLVED: To provide a method for producing a flake-shaped glass object by which the flake-shaped glass object having a smooth surface and having a desired thickness of less than 4 μm is produced by a means simpler than that of a conventional technique. <P>SOLUTION: The method for producing a flake-shaped glass object includes: a step A to form a first hollow object 6 composed of molten glass 9 by introducing a gas into the molten glass 9; a step B to bring the first hollow object 6 and at least one ring 1 for decreasing wall thickness into contact with each other; a step C to extrude the molten glass 9 in a section surrounded by points of contact with the ring 1 for decreasing wall thickness by introducing the gas into the first hollow object 6, and to make the molten glass 9 pass through the inner wall of the ring 1 to thereby form a second hollow object 7; a step D to crush the second hollow object 7 and to form the flake-shaped glass object; and a step E to recover the flake-shaped glass object. <P>COPYRIGHT: (C)2012,JPO&INPIT |
