A candle that cannot be lit is a common problem that many people experience. This issue can be caused by various factors, such as a defective wick, improper burning techniques, or the wrong wick size. In some cases, the wick may become clogged with debris or impurities, preventing it from staying lit. To address this problem, it is recommended to trim the wick regularly and ensure that the candle is burned for an adequate amount of time to allow the wax to melt evenly. Additionally, choosing the appropriate wick size for the container is crucial to prevent the wick from drowning in the melted wax and extinguishing itself. Understanding and addressing these issues can help ensure a pleasant candle-burning experience.

What You'll Learn
The wick might be defective
If your candle won't stay lit, it could be due to a defective wick. The wick is the candle component that delivers fuel to the flame. When a candle is lit, the heat melts and ignites the wax, which is drawn up through the wick via capillary action, fuelling the flame.
A candle wick may be defective if it is too short, or if it becomes clogged or drowned. A wick can become clogged when debris, impurities, or non-burnable materials are drawn into it, starving the flame of fuel. This can occur when certain additives, such as mica or crayons, are used to colour the candle. A wick may also become drowned when it is too small for the candle container, causing it to be submerged in the pool of melted wax and extinguishing the flame.
To prevent wick defects, it is important to choose the correct wick size for your candle container. Additionally, regularly trimming the wick can help to prevent clogging and promote steady burning.

The wick could be too short
A candle that cannot be lit may be referred to as having defective wicks. One of the reasons for this could be that the wick is too short.
When a candle is lit, the heat melts and ignites the wax, which is then drawn up the wick and fuels the flame. The candle shortens as the wax is consumed, and the wick burns along with it. If the wick is too short, it may not be able to draw up enough wax to fuel the flame, causing the wick to get covered in wax and the flame to extinguish. This is known as "drowning out" and often occurs when the wick is too small for the candle container.
To prevent this issue, it is important to ensure that the wick is of appropriate size for the candle container. The size of the melt pool, or the layer of liquid wax around the wick, can also help determine if a candle is properly wicked. Additionally, regularly trimming the wick can promote steady burning and prevent smoking.
If a candle with a short wick is already drowning in wax, it may be possible to save it by lighting it and letting it burn until the wax melts evenly. While the wicks may initially drown, the candle should progressively improve with each subsequent burn.

The wick is drowning in wax
The phenomenon of a wick drowning in wax is known as "drowning out". This occurs when a wick gets submerged in the pool of melted wax, typically as a result of the wick being too small for the candle container. When a wick is drowning out, it is unable to consume enough of the melted wax to remain lit. Consequently, the wick becomes covered by melted wax and extinguishes itself.
To prevent wick drowning, it is important to ensure that the wick is appropriately sized for the candle container. If a wick is too small, it will not be able to draw up enough wax through capillary action to sustain the flame. Additionally, a wick that is too large can lead to carbon buildup, resulting in a mushroom-shaped ball of carbon residue at the end of the wick. This can occur when a candle consumes more wax than it can burn.
Wick maintenance is also crucial to prevent drowning. Trimming the wick regularly with scissors or a candle snuffer can help promote steady burning and prevent smoking. By removing excess wick material, the flame is able to receive an adequate supply of wax for combustion.
Furthermore, allowing the candle to burn for an extended period during its initial lighting can help establish a proper melt pool. This refers to the layer of liquid wax that forms around the wick when the candle is lit. If the melt pool is too shallow, the wick may not be able to draw up enough wax to sustain the flame. Therefore, it is recommended to burn a candle for at least 2 hours during its first use, ensuring that the wax has melted evenly across the top.
By understanding the causes of wick drowning and implementing proper wick sizing, maintenance, and burning techniques, one can prevent this issue and ensure the optimal performance of their candles.

The wick is clogged
A candle that cannot be lit may have a clogged wick. A wick becomes "clogged" when debris, impurities, or other non-burnable materials are drawn into it. When non-burnable materials enter the wick, the flame does not have enough fuel to continue burning properly. The flame will eventually starve and burn itself out. Wicks often become clogged when additives such as mica or crayons are used to colour the candle.
A clogged wick may also be the result of the wick being too small for the candle. In this case, the wick is unable to consume enough of the melted wax to remain lit, and it will get covered by the wax and extinguish itself. This is known as "drowning out".
To prevent a wick from becoming clogged, it is important to trim it regularly. If a wick is not trimmed, carbon will build up and form a mushroom-shaped ball at the end, which will cause the candle to burn poorly.
If a candle's wick is clogged, there are a few potential solutions. Firstly, ensuring that the candle is burned for long enough each time it is lit can help. This allows the wax to melt evenly and prevents the wick from becoming submerged in wax. Trimming the wick can also help to improve the burn, as a trimmed wick will be better able to draw wax up through capillary action.
If a candle's wick is consistently unable to stay lit, it may be necessary to exchange the candle for a new one.

The candle hasn't been burned long enough
There could be several reasons why a candle won't stay lit, and one of them is that it hasn't been burned long enough. This phenomenon is called "drowning out" and occurs when the wick is too small for the candle. As a result, the wick gets submerged in the pool of melted wax and extinguishes itself. This issue can be avoided by choosing a wick that is appropriately sized for the candle container.
To determine the appropriate wick size, one must consider the diameter of the container. As a rule of thumb, the wicks should be placed in such a way that the flames will not get too close to the edge of the container. Specifically, the distance between two wicks in a double-wick candle should be equal to the distance from each wick to the edge of the container.
Additionally, it is important to note that candles have a curing time, which is the period between pouring the candle and it reaching a state where it can be lit to perform optimally. During this time, the candle sets or ages, enhancing its fragrance. The curing time varies depending on the wax and fragrance oil mixture used.
Furthermore, the act of burning a candle for an extended period and then allowing it to cool is essential for evaluating wick performance and calculating burn time. This process, known as a burn test cycle, involves burning the candle for four hours and then blowing it out. By weighing the candle before and after burning, one can calculate the hourly burn rate, which is the amount of wax consumed per hour.
By understanding these factors, one can ensure that their candle burns effectively and avoid issues such as "drowning out" caused by insufficient burning time.

Frequently asked questions
A candle that cannot be lit may be referred to as having a "drowning out" issue. This occurs when the wick is too small for the candle, causing it to be submerged in the melted wax and unable to stay lit.
To fix a candle that won't stay lit, ensure that you burn the candle for a sufficient amount of time each lighting. Avoid blowing it out until the wax has evenly melted at the top. You may also need to trim the wick regularly to prevent it from becoming clogged or too short.
Candle wicks can become clogged when debris, impurities, or non-burnable materials, such as additives used for colouring, are drawn into the wick. This prevents the flame from receiving enough fuel to burn properly, causing it to eventually extinguish.
