There are several ways to extinguish a candle flame, including blowing it out, using a wick dipper, or a candle snuffer. Another method is to put the lid on the candle. While this method does work, it is not recommended. This is because the lid traps smoke and soot within the jar, which can settle into the wax, affecting the candle's scent and appearance. It can also cause the lid to get stuck.

What You'll Learn

Using a lid to put out a candle can alter its scent
Using a candle lid to put out a flame is a popular method, as it minimises the amount of smoke and soot produced. However, this method can alter the scent of the candle.
Firstly, not all candle lids are suitable for extinguishing flames. Some lids are purely decorative and made from flammable materials such as wood, plastic, or rubber seals that can melt or deform when exposed to heat. Therefore, it is important to ensure that the candle lid is made from a non-flammable material.
Secondly, the lid traps smoke and soot within the jar, leaving black, sooty residue on the underside of the lid and the inside of the container. This trapped soot can settle into the wax, affecting the appearance and scent of the candle, especially if it is made from white-coloured soy wax.
Thirdly, repeatedly trapping smoke under the lid can gradually alter the original fragrance of the candle, causing it to smell smoky. This is because the smoke mixes with the wax, changing its scent.
Finally, if there is a lot of empty space in the container, the flame may continue to burn, creating a vacuum seal that suctions the lid tightly to the jar, making it difficult to open.
Therefore, while using a lid to put out a candle can be effective in minimising smoke and soot, it is important to consider the potential impact on the candle's scent and appearance. Alternative methods such as using a wick dipper or a snuffer can be more effective in maintaining the integrity and fragrance of the candle. These methods involve extinguishing the flame without introducing smoke or soot into the jar, thus preserving the original scent of the candle.

The lid can become stuck due to a vacuum seal
While putting out a candle with its lid can be effective, it is not recommended due to the potential hazards and negative effects it can have on the candle and its container. One of the main issues with this method is the creation of a vacuum seal, which can cause the lid to become tightly suctioned to the candle jar, making it difficult or even impossible to open again.
This vacuum seal occurs due to the depletion of oxygen inside the container. When the lid is placed on top of the burning candle, it deprives the flame of the oxygen required for combustion. As a result, the flame extinguishes as the combustion reaction between oxygen and hydrocarbons (wax) stops. However, if there is a significant amount of empty space in the container, the flame will continue to burn until it consumes all the available oxygen.
As the oxygen inside the container is gradually depleted, a vacuum seal can form, causing the lid to become stuck. This seal can be so strong that it requires significant force to remove the lid, potentially damaging the jar or the lid itself. In some cases, the lid may even become permanently sealed, rendering the candle unusable.
To avoid this issue, it is advisable not to use the lid as a primary method of extinguishing a candle. Instead, consider using alternative methods such as wick dippers or snuffers, which can effectively extinguish the flame without creating a vacuum seal or causing damage to the candle or its container. These methods also help maintain the appearance, scent, and longevity of your candles, ensuring a safer and more enjoyable experience.

Some candle lids are purely decorative
Candle lids that are not designed to extinguish flames may have decorative features that make them unsuitable for smothering a flame. For example, they may have openings or vents that allow air to circulate, or they may be made of flammable materials that could catch fire. In some cases, the lid may be purely for aesthetic purposes, with no functional value at all.
Even if a candle lid is made of a non-flammable material, it is not always safe to use it to put out the candle. The lid may not fit snugly enough to deprive the flame of oxygen, or it could have rubber seals or other components that could melt and create a mess. Additionally, using the lid to extinguish a candle can leave black, sooty residue on the underside of the lid and on the insides of the container, affecting the appearance and scent of the candle.
Furthermore, the trapped smoke and soot can alter the original fragrance of the candle, causing it to take on a smoky smell. This can be especially undesirable for scented candles, as it can ruin the intended aroma. The trapped smoke and soot can also settle into the wax, discolouring it and affecting the overall appearance of the candle.
Instead of using the lid, it is recommended to use alternative methods to extinguish candles, such as wick dippers or snuffers, which can effectively put out the flame while preserving the beauty and scent of the candle. These tools are designed to safely extinguish candles without causing smoke or wick damage, ensuring a longer-lasting and more enjoyable candle experience.

Blowing out candles is a popular but less effective method
Blowing out candles is a popular way to extinguish them, but it is not the most effective method. While it may seem like a quick and easy way to put out a candle, blowing can cause hot wax to splatter, which is not only messy but also potentially dangerous. Additionally, blowing out a candle may not fully extinguish the flame, leaving behind a smouldering wick that could reignite.
One alternative method is to use a candle snuffer or wick dipper. Candle snuffers are designed to safely extinguish candle flames without causing smoke or damaging the wick. Wick dippers, on the other hand, gently extinguish the flame by dipping the wick into the wax, preventing smoke and preserving the candle's aroma. These tools are inexpensive and can be purchased online or at most home goods stores.
Another option is to use the candle's lid to deprive the flame of oxygen and extinguish it. However, this method is controversial. While some people claim that it produces less smoke and preserves the candle's scent, others argue that it can lead to soot production and unexpected hazards. Additionally, the lid may not be designed to withstand the heat, and it could melt or deform. If the lid is not properly ventilated, it can also create a vacuum seal, making it difficult to remove.
To avoid these issues, it is recommended to gently place the lid on top of the candle jar without pushing down or sealing it. This will allow the flame to go out while still allowing smoke to escape. However, it's important to use caution and ensure that the lid is not made of flammable or heat-sensitive materials.
Overall, while blowing out candles may be the most common method, it is not the most effective or safest option. By exploring alternative methods such as using a candle snuffer, wick dipper, or the candle's lid, you can extinguish your candles more effectively while also preserving their appearance and scent.

Better alternatives include wick dippers or snuffers
While using a candle's lid to extinguish it may be tempting, it is not recommended. This is because the lid traps smoke and soot within the jar, leaving a black, sooty residue on the underside of the lid and on the insides of the container. This can alter the original fragrance of your scented candle, giving it a smoky smell. The trapped smoke can also settle into the wax, affecting the appearance of your candle. In addition, if there is a lot of empty space in the container, the flame will continue to burn, using up all the oxygen inside and creating a vacuum seal that suctions the lid tightly to the candle jar, making it difficult to open again.
If you do not have access to a wick dipper or snuffer, another way to extinguish a candle without blowing it out is to tip the jar so that the wax extinguishes the flame. Rotating the jar will ensure that the entire top layer of wax has melted, preventing tunnelling and ensuring an even burn throughout the candle's life.
