Glass article manufacturing method

A manufacturing method for a glass article, the manufacturing method comprising:

• a supply step of supplying glass raw materials onto molten glass accommodated in a melting chamber of a glass melting furnace from a plurality of supply units mounted to a front wall of the melting chamber in parallel;
• a melting step of melting the supplied glass raw materials through heating;
• and
• 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 the glass raw materials supplied from one supply unit and another supply unit, which are adjacent to each other out of the plurality of supply units, extend in parallel along a flowing direction of the glass raw materials from a front wall side to a rear wall side through intermediation of a gap on the molten glass,
• wherein the glass raw materials are melted through heating only with electrodes each immersed in the molten glass in the melting chamber, and
• wherein when a distance from the front wall to the glass raw material located on a most downstream side along the flowing direction is L1 and a length of a surface of the molten glass along the flowing direction is L2, L1 and L2 satisfy a relationship expressed by 0.65L2≤L1≤0.95 L2.
