The combustible material in a candle—or its fuel—is the wax. As the wick burns down the heat of the flame melts the wax around the wick. Because the wick is absorbent it sucks the liquid wax into the wick and upward into the flame. Once the liquid wax gets hot enough, it then turns from a liquid into a gas.
How does a candle wick not burn up?
The reason the wick does not burn is because the vaporizing wax cools the exposed wick and protects it. You may have seen the camping trick of boiling water in a paper cup. The cup does not burn because the water inside cools it. The liquid wax does the same thing for the wick.
How does a wick burn?
When you light a candle wick, the wax around the base of the wick melts. Through capillary action, this liquid hot wax is drawn up the wick. The heat of the flame turns the wax into a hot gas (a.k.a. vaporizes it) and starts to break down the wax into molecules of hydrogen and oxygen.
What does the wick do in a candle?
The wick is the braided cotton that conveys (or wicks) the fuel — which is the wax — to the flame. If the wick is too tall, it could supply too much fuel to the flame too quickly, creating excess smoke and soot.
How do candle wicks last so long?
The wick absorbs the liquid wax and pulls it upward. The heat of the flame vaporizes the wax, and it is the wax vapor that burns. It continues to form as long as the wick is hot enough to vaporize paraffin.
Why do you think the flame died when the candle was covered with the jar?
Why does a candle stop burning when covered with a glass tumbler? Candle burning requires oxygen and that is present in the air naturally. When we close the candle with jar, then oxygen flow is limited and once all the oxygen present is exhausted the candle gets extinguished.
Where does the wax go when you burn a candle?
When candles burn, most of their matter goes into the air. The light and heat from a candle comes from the wax burning. When you light the wick, the flame causes some of the wax to melt, flow up the wick and evaporate, and then the wax vapor burns.
Is a candle wick just string?
Small candles only need single wicks while medium candles require a wick made from three strands of twine braided together. If you plan to braid your wick, cut three equal lengths of twine that are four inches longer than the height of the candle the wick will be used for.
Why does only the wick burn?
because the candle not only melts it, it vaporizes it and burns the vapor. That is why there is a flame. The wick only burns as a side effect … it’s job is to transport liquid wax to be burned as vapor. You can make a candle wick out of glass tubing that does not burn.
What is actually burning when you light a candle?
When you light a candle, the heat of the flame melts the wax near the wick. The heat of the flame vaporizes the liquid wax (turns it into a hot gas), and starts to break down the hydrocarbons into molecules of hydrogen and carbon.
How do I know which wick to use?

Do candle wicks need to be waxed?
The short answer is no. However, a pre-waxed wick will improve the performance of the wick and is considered superior in the candle-making world, especially when it comes to a great scent throw! And if you don’t buy cotton, paper, or hemp wick pre-waxed wicks – you’ll need to wax them yourself.
What is the purpose of this wick?
The purpose of a wick is to deliver fuel (wax) to the flame. Acting like a fuel pump, the wick draws the liquefied wax up into the flame to burn.
What happens if you let a candle burn all the way down?
The National Candle Association (www.candles.org) states that the reason to not burn the wax (in a container or just a candle itself) all the way down is SAFETY. A glass jar or container can become too hot, causing it to break or shatter and possibly causing a fire as well as other damage.
Do you have to burn a candle to the edge every time?
The best way to fix candle tunneling is to prevent it from happening in the first place. And it’s very simple, too. To prevent tunneling, all you need to do is burn your candle long enough each time so that the entire top surface of wax is melted.
Do candle wicks expire?
Scented Candles and Shelf Life While the wax and wick in a candle never go bad, the fragrance oils in a candle do expire. Over time, the oils will dissipate so the candles won’t have as much of a scent when burned.
