    摘要： Provided is a method for producing a glass material by a containerless levitation technique, which enables production of a large-sized glass material. The method includes the steps of: preparing a forming member and a cover member 20, the forming member including a gas jetting portion 11 in which a plurality of gas jet holes 12 for use in levitating a block of glass raw material are formed, the cover member 20 which is capable of covering a peripheral portion of a gas jetting surface 13 of the gas jetting portion 12 and in which a controlling surface 21 controlling, near the peripheral portion of the gas jetting surface 13, a flow of gas jetted through the gas jet holes 12 is formed and an opening 25 capable of releasing the gas to outside is formed; placing the block of glass raw material on top of the gas jetting surface 13 and covering the peripheral portion of the gas jetting surface 13 with the cover member 20; and heating the block of glass raw material to melting while holding the block of glass raw material levitated by jetting the gas through the gas jet holes 12 and then cooling the melted block of glass raw material.

    摘要： Provided is a method that can manufacture a glass plate having a curved surface shape with high surface accuracy even without polishing the surface after forming and a glass plate manufactured by the method. The method of manufacturing a glass plate having a curved surface shape includes the steps of: preparing an original glass plate, a forming die (10) including a recess (11) corresponding to the curved surface shape, and a forming tool (20) operable to press the original glass plate (2); placing the original glass plate (2) on the recess (11) in the forming die (10); heating the original glass plate (2) and the forming die (10); maintaining a temperature of a surface of the recess (11) in the forming die at a temperature lower than a temperature of the original glass plate (2); and giving the original glass plate (2) the curved surface shape by pressing the heated original glass plate (2) with the forming tool (20) to deform the original glass plate (2) while bringing the original glass plate (2) into contact with the surface of the recess (11).

    摘要： Provided is a mobile-display cover glass less susceptible to damage from impact caused upon dropping of a mobile display. A mobile-display cover glass (1) is a mobile-display cover glass configured to cover a display region (2a) and at least a portion of a side surface (2b) of a mobile display (2). The mobile-display cover glass (1) includes a flat sheet-like front portion (11) and a side portion (12, 13). The front portion (11) is configured to be disposed in front of the display region (2a). The front portion (11) extends in a first direction and a second direction perpendicular to the first direction. The side portion (12, 13) is configured to be disposed lateral to the mobile display (2). The side portion (12, 13) includes a bent portion (12a, 13a). The bent portion (12a, 13a) bends backward from one end of the front portion (11) in the first direction. A corner (12c, 13c) of the side portion (12, 13) has a rounded shape.
