A burner for melting glass forming batch material includes a burner assembly constructed and arranged with a first passage for providing a fuel stream and a second passage for providing an oxidant stream, the first and second streams coacting to produce a supersonic combustion jet flame penetrable into glass melt. A method for melting glass forming batch material is also provided and includes providing a fuel stream; providing an oxidant stream; mixing the fuel and oxidant streams with sufficient force for providing a supersonic combustion jet flame; directing the supersonic combustion jet flame to contact the glass forming batch material; and penetrating the glass forming batch material to a select depth with the supersonic combustion jet flame.
