1. A method for manufacturing a glass article, the method comprising a heating step that heats a heating object made of glass, wherein
the heating step includes heating the heating object by converting, by a converter arranged between the heating object and a radiant heat source that radiates infrared light, a spectrum of the infrared light radiated from the radiant heat source and causing the heating object to absorb the infrared light radiated from the converter,
the converter includes:
an infrared light absorber that generates heat by absorbing the infrared light radiated from the radiant heat source; and
an infrared light radiator made of a silicon-containing material, the infrared light radiator being heated through thermal conduction from the infrared light absorber, wherein the infrared light absorber defines a space through which the infrared light radiated from the radiant heat source is transmitted through, and at least part of a surface of the converter facing the heating object includes at least part of a surface of the infrared light radiator.
