A glass sheet accommodating jig (1) accommodates a plurality of glass sheets (2) under a state in which the plurality of glass sheets (2) are arranged upright at intervals in a thickness direction in order to immerse the plurality of glass sheets (2) in a chemical tempering liquid. The glass sheet accommodating jig (1) includes a string-shaped body (7) being formed of at least one metal fiber. An end portion (2a) of the glass sheet (2) is supported by a V-shaped recess (7c) formed by intersection of a pair of string-shaped bodies (7a and 7b).

A method of manufacturing a glass bent sheet includes a printing step (S1), a provisional sintering step (S2), and a crystallization step (S3). In the printing step (S1), a paste including glass powder that contains an alkali metal oxide as a component and a pigment is printed onto a flat sheet-shaped glass substrate formed of a LAS-based crystallizable glass. After the printing step (S1) and before the crystallization step (S3), in the provisional sintering step (S2), the paste printed onto the glass substrate is heated at a temperature equal to or higher than a softening point of the glass powder plus 20C and lower than the highest heating temperature in the crystallization step (S3). In the crystallization step (S3), the glass substrate having the paste printed thereon is subjected to bending work by heating, and the crystallizable glass is crystallized by heating.

Provided is a top plate for a cooking device including a glass sheet (2) and a light-shielding film (3) formed on a lower surface (2c) of the glass sheet (2) through sputtering. The light-shielding film (3) contains an oxide, a nitride, or an oxynitride of a transition metal of Group 6 to Group 11 on the periodic table. In this manner, a color close to grey can be achieved as a color of the light-shielding film (3) while insulating properties of the light-shielding film (3) are secured.


A method of producing a glass film includes forming an inorganic thin film on a surface of a supporting glass so that a surface of the inorganic thin film after being formed has a surface roughness Ra of 2.0 nm or less after film formation, and forming a glass film laminate by laminating a glass film having a surface roughness Ra of 2.0 nm or less on the surface of the inorganic thin film in a state of being in contact with each other. The method also includes carrying out treatment involving heating with respect to the glass film laminate, and peeling off the glass film from the supporting glass after the treatment involving heating.

A method of manufacturing a glass roll, includes: a forming step (S1) of forming, while conveying a glass film, the glass film by a downdraw method; a temporary rolling step (S3) of rolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying in the forming step (S1), to thereby manufacture a source glass roll; and a main rolling step (S4) of unrolling, while conveying the glass film to a downstream side, the glass film from the source glass roll, and then rerolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying, to thereby manufacture a glass roll. Higher tension in a rolling direction is applied to the glass film in the main rolling step (S4) than in the temporary rolling step (S3).
