Video Narration

A Bunsen burner is lit and adjustment of the air inlet changes the yellow, fuel rich flame, into a transparent flame with several regions. A wire probes the flame to reveal the presence of a cool preheating region containing unburned methane and oxygen. Scorching a heat resistant board shows the presence of the blue luminous inner cone and the outer mantel. The board is used to show the flame profile. The hottest part of the flame is just above the inner cone. A match placed in the preheating region does not ignite until it is moved into the inner cone.
