What Manny different types of flames can a Bunsen burner produce?

A Bunsen burner can produce three main types of flames: the yellow, luminous flame; the blue, non-luminous flame; and the roaring blue flame. The yellow flame is cooler and indicates incomplete combustion, producing soot. The blue flame is hotter and indicates complete combustion, which is ideal for heating. The roaring blue flame, achieved with a higher gas flow, provides an even hotter and more efficient flame, suitable for specific laboratory applications.
