Zusammenfassung:	PROBLEM TO BE SOLVED: To appropriately melt glass at high temperature even while suppressing a combustion chamber wall from being overheated and suppressing a combustion noise by combining a tubular flame burner used for melting glass with a density combustion technique.SOLUTION: A glass melting method comprises: burning fuel in a fuel condensed state being at an air ratio of less than 1 in at least one tubular flame burner 10a of a plurality of tubular flame burners 10a and 10b; burning fuel in a fuel diluted state being at an air ratio of more than 1 in at least the other tubular flame burner 10b; introducing a carrier gas H having floated glass raw material powder G into the combustion chambers 11a and 11b from the upstream side ends of the combustion chambers 11a and 11b; and catching and collecting glass liquid droplets generated by a molten vitrification reaction at the downstream side ends of the combustion chambers 11a and 11b.
