Candles are a great way to create a cosy atmosphere, but they can also be a fire hazard. It is estimated that candles start 8,200 home fires each year. While candles can burn out on their own, it is not always predictable, and it is unsafe to rely on this. Factors that influence whether a candle will self-extinguish include the type of wax and wick used, the length of the wick, and the amount of fuel. To increase the chances of a candle burning out on its own, place it on a stable, heat-resistant surface, and trim the wick regularly. However, it is important never to leave a burning candle unattended. Instead, always extinguish a candle before leaving the room or going to bed, using a candle snuffer, wick dipper, or your fingers.

What You'll Learn
The type of wick used
Self-extinguishing wicks are typically made from materials like zinc, tin, or metal, and are commonly found in container candles, such as glass jar candles or tealights. These wicks are designed to snuff out automatically once they reach the end of their burning time, reducing the risk of fire hazards.
On the other hand, some types of cotton wicks may continue burning even after the wax supply is depleted, requiring manual extinguishment. This highlights the importance of choosing candles with self-extinguishing wicks to prioritize safety.
The purpose of a wick is to act as a fuel pump, drawing liquefied wax up into the flame through capillary action. Different wick sizes and materials influence the amount of fuel delivered to the flame. For example, larger diameter wicks result in a larger flame and a faster-burning candle.
There are various types of wicks available, such as flat wicks, square wicks, and cored wicks. Flat wicks are commonly used in taper and pillar candles, while square wicks are preferred for beeswax candles. Cored wicks use materials like cotton, paper, zinc, or tin to keep the wick upright and provide stiffness.
Additionally, wooden wicks are a relatively new option, offering a unique crackling and popping sound when burned. Softwood wicks, in particular, are ideal for natural waxes like soy and can hold a lot of fragrance oil. However, they should only be used in containers and not in pillars or votives.

The type of wax used
Soya or beeswax candles are more likely to self-extinguish by drowning the wick in a smaller pool of liquid wax. However, this can impair the flame, and it is better to manually extinguish a candle before the wax drowns the wick. Candles with self-extinguishing wicks, made from materials such as zinc or tin, are designed to increase the likelihood of the candle going out on its own. These wicks are often found in container candles, such as glass jar candles or tealights.
The presence of a metal wick tab or sustainer also contributes to the self-extinguishing property of some candles. The wick tab keeps the wick secured and forces the candle to self-extinguish when it burns down to the top of the wick tab. An extended wick tab can be a safer option as it forces the flame to go out earlier, although this may result in more wax being left unused.
To ensure optimal burning and minimise safety risks, it is important to follow proper candle care practices. This includes regularly trimming the wick to a length of about 1/4 inch to prevent large flames and promote an even burn. Additionally, placing candles on a stable, heat-resistant surface, such as stovetops, granite countertops, or treated wood furniture, is crucial to prevent accidents.
While candles may eventually burn out on their own, it is important to prioritise safety and manually extinguish them using appropriate methods like a candle snuffer, wick dipper, or your fingers.

The importance of trimming the wick
While candles may eventually burn out on their own, it is unsafe to rely on this. The wick material significantly influences whether a candle will extinguish itself. For instance, wicks made from self-extinguishing materials like zinc or tin increase the likelihood that the flame will go out once it reaches the end of its burning time. On the other hand, certain types of cotton wicks may continue to burn even after reaching the end of their wax supply unless manually snuffed out.
Trimming the wick is an important step in candle maintenance and fire safety. Here are the reasons why wick trimming is essential:
Prolongs Candle Life and Performance
Trimming the wick helps to prolong the life and performance of your candle. When the wick is not trimmed, it can lead to a flame that is too tall, which can increase the risk of fire. A tall flame also generates too much heat, causing the candle wax to melt faster. As a result, the scent and wax vaporize more quickly, reducing the overall burn time of the candle.
Promotes a Clean and Even Burn
Trimming the wick helps to ensure a clean and even burn and consistent scent throw throughout the life of the candle. Untrimmed wicks can produce larger flames, which can result in excess smoke and soot that leaves stains on the candle vessel or nearby surfaces.
Maintains a Healthy Flame Height
A healthy flame height is typically between 1/2 inch to 1 inch. Trimming the wick to the recommended height helps to maintain a safe and optimal flame size.
Enhances Safety
Trimming the wick is a crucial aspect of candle safety. By preventing the wick from becoming too tall, you reduce the risk of large flames that could potentially cause a fire. Additionally, trimming the wick helps to minimize excess smoke and soot, which can be a fire hazard.
In summary, trimming the wick of your candle is essential for maintaining optimal performance, prolonging the life of the candle, and enhancing safety. By following the recommended wick height and trimming regularly, you can enjoy a clean, even, and long-lasting burn while reducing potential fire risks.

Self-extinguishing candles
Candles are a great way to create a cosy atmosphere, but they can also be a fire hazard if left unattended. While candles may eventually extinguish themselves, it could take hours, and in that time, a fire could start. Therefore, it is always best to practise candle safety and extinguish candles before leaving the room or going to bed.
To increase the chances of candles extinguishing on their own, place them on a stable, flat, heat-resistant surface, away from flammable objects and draughts. Additionally, ensure the wick is made from self-extinguishing materials, such as zinc or tin, which increase the likelihood that the flame will go out once it reaches the end of its burning time.
Some candles have metal wick tabs, also known as wick sustainers, which will self-extinguish when left to burn out. The wick tab keeps the wick secured while also forcing the candle to self-extinguish when the candle burns down to the top of the wick tab. You can also purchase a separate device, such as an automatic candle extinguisher, to make your candle self-extinguishing.
However, even with these precautions, it is important to never rely on a candle to go out on its own. Always snuff out the candle before leaving it unattended, and be sure to regularly trim the wick to prevent large flames and promote an even burn.

Candle safety tips
While candles can go out on their own, it is not always predictable, and it is unsafe to leave a candle unattended. Here are some candle safety tips to keep in mind:
Choose the right candles
Select candles with self-extinguishing wicks made from materials like zinc or tin. These wicks increase the likelihood of the candle going out once it reaches the end of its burning time. Candles with wicks that have a metal "neck" or bottom will also self-extinguish.
Prepare your space
Place candles on a stable, flat, heat-resistant surface to prevent accidents. Keep candles away from flammable objects and materials like curtains, rugs, and fabrics.
Practice proper wick maintenance
Regularly trim the wick to 1/4 inch to prevent large flames and promote an even burn. When lighting a new candle, trim the wick before placing it in its holder.
Extinguish properly
Always extinguish candles before leaving the room or going to bed. Use a candle snuffer, wick dipper, or your fingers to put out the flame safely. Avoid using water, as it can cause hot wax to spatter and potentially cause burns.
Be mindful of burning time
As a general rule, avoid burning candles for longer than four hours at a time. Allow the candle to cool for at least two hours before relighting it.
