All waxes are essentially hydrocarbons, which means they are primarily composed of hydrogen (H) and carbon (C) atoms.
The line in the middle of the candle is called the wick, which plays the role of liquid wax. When the candle is just produced, the candle wick already has solid wax oil. The solid wax oil is heated and introduced when you use the candle. After the vaporization, the wax vapor is ignited by the fire to light the candle.
When the candle burns, it releases heat to allow the solid wax oil below to contain, is sucked up by the wick, and continues to be heated, vaporized, and ignited by the above fire to form a cycle.
The flame's heat vaporizes the liquid wax (turns it into a hot gas) and starts to break down the hydrocarbons into molecules of hydrogen and carbon. These vaporized molecules are drawn up into the flame, where they react with oxygen from the air to create heat, light, water vapor (H2O), and carbon dioxide (CO2).
Approximately one-fourth of the energy created by a candle`s combustion is given off as heat radiates from the flame in all directions.
Enough heat is created to radiate back and melt more wax to keep the combustion process going until the fuel is used up or the heat is eliminated.
It takes a few minutes for this combustion process to stabilize when you first light a candle. The flame may flicker or smoke at first, but once the process is stabilized, the pet will burn cleanly and steadily in a quiet teardrop shape, giving off carbon dioxide and water vapor.
A quietly burning candle flame is a very efficient combustion machine. But if the pet gets too little or too much air or fuel, it can flicker or flare, and unburned carbon particles (soot) will escape from the love before they can fully combust.
The wisp of smoke you sometimes see when a candle flicker is caused by unburned soot particles that have escaped from the flame due to incomplete combustion.
The candle is a beautiful thing. After you use it, you will find his wonderful things, and you will not be able to separate from it.
