A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction made in a thin zone. [ 1 ] When flames are hot enough to have ionized gaseous components of sufficient density, they are then considered plasma .
The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. [2] Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. [3]
A reducing flame is a flame with insufficient oxygen. It has an opaque yellow or orange color due to carbon or hydrocarbons [3] which bind with (or reduce) the oxygen contained in the materials the flame processes. [2] The flame is also called carburizing flame, since it tends to introduce carbon soot into the molten metal.
Similarly, while oxygen is relevant to sustain a flame, weather and associated winds feed oxygen into a spreading fire, and the longer-term pattern of weather is summarized as climate. Lastly, fuels is the term to describe what burns in a single flame to the range of materials burnt in a spreading wildfire, but fuels vary over larger space and ...
The Chemical History of a Candle was the title of a series of six lectures on the chemistry and physics of flames given by Michael Faraday at the Royal Institution in 1848, as part of the series of Christmas lectures for young people founded by Faraday in 1825 and still given there every year.

A candle flame is formed because wax vaporizes on burning. A candle flame is widely recognized as having between three and five regions or "zones": Zone I – this is the non-luminous, lowest, and coolest part of the candle flame. It is located around the base of the wick where there is insufficient oxygen for fuel to burn.
