Abstract
A manufacturing method for a glass article includes a supply step of supplying a glass raw material onto a surface of a molten glass accommodated in a melting chamber of a glass melting furnace from a supply unit mounted to a front wall of the melting chamber, and a melting step of melting the supplied glass raw material through heating with an electrode immersed in the molten glass in the melting chamber. The method also includes an outflow step of causing the molten glass to flow outside the melting chamber from an outflow port provided at a rear wall of the melting chamber, wherein 60% to 95% of an area of the surface of the molten glass in the melting chamber is covered with the glass raw material supplied in the supply step.
