There are several reasons why a candle flickers, including the length of the wick, the quality of the wax, and air drafts. In this article, we will explore the common causes of candle flickering and provide solutions to fix this issue, ensuring you can safely enjoy the warm and enchanting atmosphere that candles create.

| Characteristics | Values |
|---|---|
| Reason for flickering | Wind or draughts, impurities in the wax, carbon build-up, incorrect wick size, manufacturing defects, improper storage, air bubbles, dust, dirt, moisture, low-quality wax |
| Prevention techniques | Trim wick to 0.5 cm-1 cm after each burn, ensure adequate ventilation, burn for at least an hour, keep candle covered when not in use, opt for high-quality wax, ensure proper storage, choose candles with well-constructed wicks |

What You'll Learn
Avoid placing candles in windy areas
A candle's flame is fed by the circulation of oxygen and wax. A slight breeze or draught can cause a candle to flicker as the air movement around the flame disrupts the combustion process. Windy areas can also cause the flame to dance, leading to an inconsistent flame. This can be dangerous as it can cause the candle to burn quicker and become a potential fire hazard.
To avoid this, it is important to position candles away from open windows, air vents, or fans. Windy areas can cause the flame to flicker and produce more soot. A flickering flame can also be a sign of impurities in the candle or carbon build-up. If the candle is left uncovered, it can collect dust, dirt, or moisture, which can contribute to flickering once the candle is lit.
In addition to external factors, the candle's wick can also cause unusual flickering. A wick that is too long or too short can cause the flame to flicker. This is because the wax has to travel up the wick, and if it is too long, it affects the stability of the flame. A wick that has ""mushroomed"" will also cause the flame to be irregular.
To prevent your candle from flickering due to wind or draughts, ensure it is placed in a still area, away from any open windows or fans. Keep the wick trimmed to about 0.5cm to 1cm for a steadier, cleaner burn. Also, check that the candle has been stored correctly and has no dirt or moisture on it before lighting.

Trim candle wicks to 0.5cm or 1/4 inch
A candle's wick plays a crucial role in the flame's stability. If the wick is too long, the wax has to travel up the wick, affecting the flame's stability and causing it to flicker. Additionally, a longer wick can cause the candle to burn through wax more quickly, reducing its overall burn time.
Trimming the wick to the correct length is essential for a steady and clean burn. The recommended length for a trimmed wick is 0.5 cm or 1/4 inch. This ensures the wax and the wick are in proper balance, preventing the flame from flickering and emitting black smoke.
By trimming the wick, you can also prevent mushrooming, a term for the carbon build-up that occurs on burned candles. This build-up can cause the flame to become irregular and flicker. Therefore, it is advisable to trim the wick after each burn to maintain the optimal length and prevent flickering.
It is worth noting that different sources suggest slightly different optimal wick lengths. While some recommend trimming the wick to 0.5 cm, others suggest 1/4 inch (approximately 0.6 cm). Trimming the wick within this range will help ensure a steadier flame and reduce the likelihood of flickering.
In addition to wick length, other factors such as air drafts, wax quality, and impurities in the wax can also contribute to candle flickering. However, maintaining the appropriate wick length is a crucial step in reducing flickering and improving the overall burning experience of your candles.

Store candles correctly
Storing candles correctly is essential to maintaining their shape, scent, and colour. Here are some tips to ensure your candles remain in good condition:
Choose a Suitable Storage Location
Select a dry, enclosed, and dark place, away from direct sunlight and heat sources like windows, vents, radiators, or kitchen appliances. A cool, temperature-controlled environment, such as a basement storage room, a shelf in a guest room, a linen closet, or an under-the-stairs closet, is ideal. The temperature should remain consistent, ideally between 50 and 85 °F (or no higher than 28 °C), with low humidity.
Organise and Protect Your Candles
Keep like items together and organise your candles by type, scent, or colour to easily find what you need. Use coasters under the candles to protect shelves. For candles without lids, consider using elegant bell cloches to display them while preserving their fragrance. Additionally, cover or bag your candles when not in use to maintain their scent and keep dust and moisture out.
Ensure Safety and Accessibility
Always prioritise safety by storing candles out of the reach of children and pets. Store heavier items on shelves between shoulder and mid-thigh height, ideally at waist height. Avoid placing candles in areas prone to leakage, such as under sinks, and be mindful of potential oil seepage from ceramic or cement candle jars, which can damage furniture.
Rotate and Display Your Candles
Regularly rotate your candle collection to use older candles first. There is no time limit on how long you can store a candle, and displaying them can be part of your decor. Feel free to leave candles on display in guest rooms, on bedside tables, or even on a bar cart to set the mood.

Opt for candles made from high-quality wax
While a small, natural flicker in any candle is normal and can even be appealing, excessive flickering can become a fire hazard and affect the overall burn time of the candle. One of the biggest reasons for flickering is wind or draughts. If the draught is strong enough to move curtains or blinds, it will definitely affect a candle's wick and flame.
Another reason for flickering is the size of the wick. Candles with large wicks burn through wax too quickly, causing the flame to flicker. Conversely, wicks that are too small create an uneven wax pool, leading to tunnelling. The wick may also have ""mushroomed",", which refers to a carbon build-up on a burned candle, resulting in an irregular flame. These issues can be resolved by trimming the wick after each burn to 0.5cm.
To prevent flickering caused by impurities in the wax, ensure that your candle is stored away from draughty areas and kept covered when not in use to prevent the collection of dust and moisture. Regularly wipe your candle with a dry cloth to remove any dust, soot, or grime, and always burn your candle for at least an hour to allow enough time for the wax pool to build up.
To summarise, opt for candles made from high-quality wax that is clean and non-toxic, as this will ensure a safer burning experience and reduce the likelihood of flickering. Additionally, pay attention to the size of the wick and follow the recommended steps to minimise the negative impact of wind or draughts. By following these steps, you can create a relaxing and safe atmosphere with your candles.

Ensure the candle is well-ventilated
A candle's flame is fed by the circulation of oxygen and wax. If the flame gets too much or too little air or wax, it can flicker or flare up. Therefore, it is important to ensure that your candle is placed in a well-ventilated area.
Firstly, avoid positioning your candles near open windows, air vents, or fans, as these can create drafts that cause the candle to flicker. Even the slightest breeze or draft can disrupt the combustion process, causing the flame to dance. If a draft is strong enough to move curtains or blinds, it will definitely affect a candle's wick and flame.
Secondly, be mindful of the surrounding objects and their potential impact on airflow. For example, if your candle is burning near fabric, the flame can get high and become a potential fire hazard. Keep flammable materials at a safe distance from the candle to prevent accidents and ensure adequate air circulation around the flame.
Additionally, consider the size and number of candles in the space. Burning multiple candles in a confined area may result in insufficient oxygen for each flame, leading to flickering. Ensure there is enough ventilation in the room to accommodate the number of candles you intend to light.
By following these ventilation guidelines, you can help minimize flickering and create a safer and more enjoyable candle-burning experience.
