The wax of the candle and some oxygen in the air are converted into some carbon soot, water vapor, some complex hydrocarbons in the smoke, and carbon dioxide.
If you stand a small candle on a saucer and cover it with a tall glass, you can see each of these things. The candle will burn the oxygen in the glass. You will see the carbon dioxide and smoke fill the bottom of the glass. You will see a little water condense on the side of the glass, and the top of the glass will be blackened with the soot.
When the level of smoke and CO2 reach the level of the flame, the candle will go out.

∙ 13y agoat the beginning you are in extreme pain and run to the closest tap and leave your hand in a bowl of ice cold water. normally you have to wait about half an hour before taking it out and putting a damp towel over it. then the next day, or later on in the day, there is red and if it is hot candle wax your skin peels and the burnt area goes red and you get a huge swelling that is filled with a sort of clear gel. it then becomes very agitating and annoying but the pain goes down. I'm not sure how long it lasts.

∙ 13y agoIf we look at a burning candle, we'll see that the wax (paraffin) is melting and being wicked up to the flame where it burns. The wax is a complex hydrocarbon, and the heat of the continuous chemical reactions in the flame breaks the hydrocarbon chains in the presence of oxygen to form (idealy) carbon dioxide and water. If you're interested in the actual chemical reaction, use the link below to the related question. You'll find the basic equations there.

What candle burns out first an oil candle or a wax candle?
Generally more energy is in a solid versus a liquid, so a wax candle will have more energy than an oil based candle which means the solid wax candle will burn out last over the oil one. Actually, I can't think of a case where the reverse is true. And btw, wax candle has around 42 kJ/g with oil candle being around ~30 kJ/g (type of oil will make a difference here). tho' i agree with most of the above, the most important part of any candle is the oil/oil byproduct/animal fat or beeswax that it is made from! a wax candle will NOT burn until it heats up enough to dissolve into an oil - which occurs between 140-160 degrees! therefore, an oil candle and a wax candle burn out at the same time!
Which is to burn longer a tallow candle or a wax candle?
If you freeze the candle, before using it, it will burn for a longer period of time. ANSWER Beeswax burns very quickly.
Energy flow diagram for a candle?
The wax in the candle contains chemical energy. When you burn the candle the chemical energy is transferred into heat (thermal) and light energy.
Why does the wick in my scented candle burn fast and the wax builds up the sides and makes a big hollow in centre of andle leaving hardly any wick?
How long have you been allowing your candle to burn at a time? Most candles have a minimum length of time that they must burn in order for the wax to melt evenly. If you are burning your candle for a shorter period of time than is recommended, then the wax near the wick is melting, but the wax further from the wick isn't getting hot enough to melt. It takes time to heat up the wax near the outside edges of these candles.
Does size and shape affect how candles burn if the candles have the same amount of wax?
The shape and angle of candle will effect how long a candle burns because when a candles reaches the middle of glass jar candle, the lack of oxygen to feed the fire causes it to go out.
Why doesn't the wax on a candle burn?
Well the wax on a candle doesn't burn because of how it is made. The waX does melt though.
What is the difference between melting of candle wax and burning of candle?
Burning a candle is the process in which the wick is burnt. The wax is there to make the wick burn slower in order to let the candle burn for longer. Melting wax is part of the process but not burning the candle itself.
How fast does a candle burn?
It depends on what kind of wax that the candle is made out of
Is candle wax melting physical property?
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
Does a candle need to have wax for it to burn?
No. Not all candles are made of wax. A candle can be made of soap, oil, fat.
When you burn a candle what happens to the wax?
it floats away
Does the thickness of a candle affect the burn time of a candle?
Yes, thicker candles have more wax to burn and therefor take longer to burn out.
Is melting wax physical property?
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
How do you get your three wick candle to burn even?
Remove some wax and re-burn the candle to level out the wax melt. When the candle wax is solid, carve out a "moat" from the wax, around the circumference of the candle, by running a knife (or spoon) around the edge of the glass. Depending on how short your wicks have gotten, make your moat about 1/2" deep by 1/2" wide (for a 4" diameter candle). It doesn't have to be pretty; it'll all smooth out when re-burning. Next, scoop out the wax berms between the three wicks and in the middle of the candle. Depending on how shallow your wicks have gotten, you could go 1/4" to 1/2" deep here. Then relight the candle and let it burn for several hours until the wax has re-leveled itself. You can help it along by gently tilting the candle in a circle after about an hour of burn time. Repeat as needed.
What makes a white and colored candle burn?
Not depending on the color, it's always the wax that lets the candle burn. Near the flame, the wax melts until its gaseous and this paraffin gas is burned.
How does oxygen Affect how fast a candle will burn?
when a candle burns, the wax is reacting with oxygen in the air to give out heat and light. If you give the candle more oxygen then it will burn brighter, but it will burn out more quickly. It all depends whether the candle has a high or low concentration of oxygen. The main reason why the candle burns brighter is because there is a better chance that the oxygen will bump into the wax on the wick. when a candle burns, the wax is reacting with oxygen in the air to give out heat and light.
