PROBLEM TO BE SOLVED: To obviously form the unevenness of a die pattern without causing the break of a striped die pattern in a glass ribbon and in a figured glass made by cutting it. SOLUTION: An apparatus for producing a figured glass is provided, which transfers, to a glass ribbon, a figured pattern which is on the surface of a die roll and is used for a pair of molding rolls for roll out molding of a fused glass into a glass ribbon having a figured pattern on at least one surface. The apparatus is characterized by using the die roll of which the surface is etching processed. COPYRIGHT: (C)2009,JPO&INPIT
