Caption: Bunsen burner flame. This device burns hydrocarbon gases (supplied through the rubber tube at left) to produce a flame. It is used in the laboratory as a heat source in experiments, or for flame tests. The vent is in a mostly closed position, which leads to a yellow flame. Opening the vent further draws air into the combustion mixture, leading to a stronger, hotter, blue flame. For a sequence and montage showing the different types of bunsen burner flames, see images C010/9562 to C010/9566.
