Abstract: A method for manufacturing a formed glass includes using a heating apparatus. The heating apparatus includes a heating element and a heat reservoir having a transmittance of 50% or more in a wavelength of 0.5 um to 2.5 um. The heat reservoir is arranged between the heating element and a glass substrate as an object to be heated. The glass substrate is heated with the heating element, and the glass substrate is formed into a desired shape.

Abstract: A method for producing a glass article from a glass member including a glass substrate including a first main surface, a second main surface and an end face, and an irregular layer formed in at least one of main surfaces, includes forming an irregular layer having a glass transition point Tg which is equal to or lower than a glass transition point in a central part of the glass member in a thickness-direction sectional view and performing a heat treatment on the glass member so as to have an equilibrium viscosity in the central part of the glass member in thickness-direction sectional view of 1017 Pa·s or lower.

Abstract: A method for manufacturing a bent substrate, which forms a bent part in at least a part of a substrate, in which the substrate includes a second region and a first region, the method for manufacturing including: supporting the first region of the substrate on a substrate support surface of a support member including a mold surface having a same curved surface shape as that of the bent part and the substrate support surface that supports the first region, in a state of facing the second region of the substrate to the mold surface; heating the second region of the substrate to soften the second region of the substrate by the heating; placing the second region along the mold surface of the support member by an own weight of the second region; and transferring the curved surface shape of the mold surface to the second region by an external force.

Abstract: A mold has a molding surface for hot molding of a body to be molded. The mold includes a glass having a porosity of 0.01% or more and containing 95 mol % or more of SiO2. A molding apparatus includes the mold. A method for producing a bent glass includes a placing step and a molding step. In the placing step, a glass to be molded is placed on a mold including a glass having a porosity of 0.01% or more. In the molding step, the glass to be molded which has been placed on the mold is heated, and then, the glass is caused to be molded to follow a molding surface of the mold.
