There are several reasons why a candle might keep going out. The most common cause is a problem with the wick, such as incorrect length, manufacturing errors, or contamination by hard wax, additives, dyes, or flavours. Another issue could be the type of fragrance oil used, which may contain non-combustible ingredients that eventually starve the flame of fuel. Drafts can also cause a candle to go out by removing the heat required for combustion.

What You'll Learn
The wick is too short
If your candle keeps going out, one possible reason could be that the wick is too short. This is a common issue, especially with candles that have been burned for a long time or those that were not initially wicked correctly. When a wick becomes too short, it cannot draw enough wax up from the candle to fuel the flame, resulting in a weak flame that may flicker and eventually go out.
To fix this issue, you should first trim the wick to the appropriate length. The ideal wick length for most candles is between 1/4 and 3/8 of an inch. If your wick is too long, it can become unstable and produce a large, uncontrolled flame that can be dangerous. Use a wick trimmer or scissors to cut the wick to the correct length.
However, if the wick has burned too far down into the candle, you may need to take additional steps to fix the issue. Try pouring out some of the melted wax around the wick to create a lower wax level and expose more of the wick. Be very careful when doing this, as the hot wax can cause serious burns. Always handle hot candles with caution and use heat-resistant tools if possible.
If there is not enough wax to pour out, or if the wick is still too short, you may need to add more wax to the candle. This can be done by carefully pouring hot, melted wax into the candle around the wick. Ensure the wax you add is similar in type and color to the original wax, and take care not to spill any hot wax.
Finally, after addressing the wick length and ensuring there is enough wax to fuel the flame, light your candle again and observe if it stays lit. You may need to readjust the wick length or add more wax if the issue persists. Always practice candle safety, including keeping candles away from drafts, flammable materials, and children or pets.

The wick is flooded with wax
One of the most common reasons a candle flame blows out is due to a flooded wick. This occurs when the wick becomes saturated with melted wax, causing the flame to suffocate and eventually extinguish. There are several reasons why a wick may become flooded, and understanding these can help you prevent the issue from reoccurring.
When a candle is lit, the heat of the flame melts the solid wax nearby, creating a pool of liquid wax. This liquid wax is then drawn up through the wick by capillary action, providing fuel for the flame. However, if the pool of melted wax becomes too deep, it can submerge the wick, causing it to become saturated. This is especially common in candles with wide or shallow containers, as the wick is more likely to be surrounded by a deep pool of wax.
Additionally, some types of wax are more prone to causing wick flooding than others. For example, soft or highly-fragranced waxes tend to melt more easily, increasing the risk of wick flooding. Using the wrong size or type of wick for your candle can also contribute to the issue. If the wick is too large, it may produce a flame that is too big for the candle, leading to excessive wax melting and wick flooding. Conversely, if the wick is too small, it may not be able to draw up the wax quickly enough, resulting in a flooded wick.
To prevent wick flooding, it's important to trim the wick to the appropriate length before lighting your candle. A wick that is too long can interfere with the flame's ability to burn properly, leading to smoking and wick flooding. It's also helpful to allow your candle to burn long enough to create an even wax pool that reaches the edges of the container. This helps ensure that the wick is not surrounded by excess wax, reducing the risk of flooding. If your candle does exhibit wick flooding, it's best to let the wax cool and harden, trim the wick, and then relight the candle, being mindful of the issues that may have caused the flooding.

Fragrance oil contains non-combustible ingredients
One of the reasons why your candle keeps going out is that your fragrance oil may contain non-combustible ingredients. These non-combustible ingredients accumulate in the melt pool as the candle burns. Eventually, the melt pool may contain so much non-combustible material that it can no longer fuel the flame, causing the candle to go out. This often occurs with fragrances from generalist stores, as they may not be optimised for candle-making.
To avoid this issue, it is important to purchase fragrances that are optimised for candles. Reputable suppliers like Candle Shack have fragrances that are tested and optimised for candle use. It is also recommended to be cautious of suppliers that offer a wide range of fragrance oils marketed as suitable for various purposes, such as candles, soaps, and carpet fresheners. These products may not have undergone sufficient testing.
Additionally, some fragrance oils that are not optimised for candle-making can effectively "cook" the wick, turning it into charcoal and preventing capillary action. This results in the flame being starved of fuel and eventually going out.
To ensure the safety and quality of your candles, it is advisable to choose fragrance oils that are non-toxic and free from harmful chemicals. Look for certifications such as "phthalate-free," "paraben-free," and "formaldehyde-free," which indicate that the product has been tested and certified by regulatory bodies. Reputable companies like Aroma Retail offer fragrance oils that are free from harmful toxins, allergens, disruptors, carcinogens, and pollutants.
By selecting fragrance oils from trusted sources and ensuring they are optimised for candle-making, you can help prevent issues with your candles going out and also maintain a healthy home environment.

The wick is too large
If your candle keeps going out, it could be because the wick is too large. A wick that is too large will consume too much fuel too quickly, generating excessive heat and melting only the middle of the candle. This issue is less common, but it does occur.
To address this problem, you can try adjusting the wick size. Start by going down a size, choosing a slightly smaller wick, and observing if that makes a difference. A smaller wick may burn more slowly and efficiently, ensuring that the candle wax melts at a similar rate to the wick's fuel consumption.
Additionally, consider the type of wick you are using. Laminar wood wicks, for example, are made from natural materials and may have knots and inconsistencies that affect their performance. Fragrance oils that are not optimised for candle-making can also affect the wick. These oils may 'cook' the wick, turning it into charcoal and impeding its ability to draw and burn fuel.
To avoid issues with your wicks, ensure you purchase fragrances that are specifically optimised for candle-making. Avoid general craft supply stores, as their products may not be adequately tested for this purpose. Seek suppliers that specialise in fragrances for candles, ensuring the quality and compatibility of your candle-making ingredients.
Finally, be mindful of the placement of your wick during the candle-making process. A wick that is inserted too loosely or positioned too far to one side can lead to uneven burning and potential issues with the candle staying lit.

Poor air circulation
To prevent this issue, ensure that your candle has sufficient air circulation by following these steps:
- Trim the wick: Before lighting your candle, use a wick trimmer or nail clippers to trim the wick to the recommended length of 3-5mm or 1/4" (6mm). Trimming the wick helps to control the size of the flame and prevent it from becoming too large or too small.
- Remove excess wax: If the wick is flooded with wax, gently remove the excess liquid wax with a spoon, chopstick, or paper towel. This process is known as "tunneling." Be careful not to scratch the glass or walls of the candle container.
- Create a well-ventilated space: Ensure that the area where you are burning the candle is well-ventilated. Open a window or create a gentle breeze to improve air circulation and prevent the flame from being extinguished due to lack of oxygen.
- Choose the appropriate wick: Use a wick that is suitable for the type of wax and fragrance combination in your candle. Some wicks may have a chemical treatment that is too strong or too weak for the candle material, causing the wick to become unstable and fall into the melt pool.
- Maintain the candle: Regularly inspect your candle to ensure that the wick is centered and secure. A wick that is inserted too loosely or placed too close to the wall of the container can affect the burn and lead to poor air circulation.
By following these steps, you can improve air circulation and help prevent your candle from going out due to insufficient oxygen or heat dissipation.

Frequently asked questions
There could be several reasons for this. Firstly, check the length of the wick. If it's too short, it might not be able to stay lit. Try keeping the wick about 1/4" or 3-5mm above the surface of the wax. If it's too long, trim it with a wick trimmer, nail clippers, or scissors.
Another common issue is the wax drowning the wick. This is known as "tunneling". Gently remove the excess wax with a spoon, wick dipper, or chopstick.
Yes, there are a few other possibilities. Your candle may have a manufacturing error, such as a wick that is too thick or too weak for the type of wax. It could also be an issue with the fragrance oil or other additives. Non-combustible materials in the melt pool can starve the flame of fuel, causing it to go out. Additionally, drafts or issues with air circulation can extinguish the flame by removing the necessary heat for combustion.
To prevent your candle from going out, ensure that the wick is trimmed to the correct length and that there is no excess wax drowning the wick. Use fragrances and additives that are optimised for candle-making, as some substances can clog or "cook" the wick, disrupting the capillary action. Additionally, avoid placing candles in drafty areas to prevent the flame from being extinguished.
Wooden wicks can be more prone to going out due to their natural imperfections. Ensure that you are using fragrances optimised for candles and that the wick is not too short or too thick. Trim the wick regularly, about every 3 hours, to prevent it from becoming too charred.
