[1] [a] At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.
Fire is the visible effect of the process of combustion – a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. The products from the chemical reaction are completely different from the starting material.
