Putting a lid on a candle to extinguish it is a common practice, but it is not without its drawbacks. While it can be an effective way to smother the flame, it can also create a vacuum effect, causing the jar to turn black and releasing soot into the air and onto the wax. This can affect the scent and appearance of the candle, and even cause the lid to get stuck. So, while it may be tempting to simply place the lid on a burning candle, it is recommended to use alternative methods such as a wick dipper or a candle snuffer to safely extinguish the flame without causing any damage to the candle or its surroundings.

What You'll Learn

Candle lids are not for extinguishing
While it is possible to put out a candle by placing a lid on it, there are several reasons why this method is not recommended. Firstly, not all candle lids are designed to be used for this purpose. Some lids are purely decorative, made from flammable or heat-sensitive materials such as wood, plastic, or rubber seals that can melt or deform when exposed to heat. Using such lids to extinguish a candle could pose a safety risk.
Secondly, using a lid to extinguish a candle can result in smoke and soot becoming trapped within the jar. This can leave black, sooty residue on the underside of the lid and the inside of the container, affecting the appearance of your candle. More importantly, the trapped soot can settle into the wax, potentially altering the scent and appearance of the candle.
Thirdly, placing the lid back on a candle while it is still hot can create a vacuum seal, causing the lid to suction tightly to the jar and making it difficult to remove. This can also result in the jar turning black due to the trapped soot. Additionally, if you fully seal the lid, the candle may continue to burn and consume oxygen, potentially leading to an unsafe situation.
Finally, there are alternative methods for extinguishing candles that are safer and more effective. Using a wick dipper or a candle snuffer are recommended options. A wick dipper involves dipping the wick into the melted wax, instantly putting out the flame with minimal smoke. A candle snuffer involves using a long-stemmed metal rod with a small cone or bell on the end to cut off the oxygen supply to the flame. This method produces a minimal amount of smoke and prevents debris from falling into the wax.

Using a candle lid can create a vacuum effect
Using a candle lid to extinguish a flame is a common practice, but it is important to do it correctly. If the candle came with a non-flammable lid, placing it on top without pushing down can effectively suffocate the flame. However, one must be cautious not to fully seal the candle with the lid. Doing so can create a vacuum effect, making it challenging to reopen the jar.
The vacuum effect occurs due to changes in air pressure and density. When the hot air inside the candle cools down, it becomes less dense and occupies less space. This results in a decrease in pressure, creating a partial vacuum with lower pressure than the atmospheric pressure outside the candle jar. As a result, the outside air pushes its way into the jar to equalize the pressure, leading to a vacuum-like seal.
To avoid this issue, it is recommended to gently rest the lid on top of the candle until the flame goes out. This allows the smoke to escape and prevents the buildup of soot or smoke inside the jar. It is also advisable to remove the lid once the flame is extinguished to facilitate the release of any remaining smoke or soot particles.
Additionally, other methods can be employed to extinguish a candle flame, such as using a snuffers or a wick dipper, which can help avoid the potential issues associated with using a candle lid. It is worth noting that blowing out the candle is not recommended as it can cause smoke to be released into the air and increase soot accumulation.
By understanding the science behind the vacuum effect and following the proper guidelines, individuals can effectively use a candle lid to extinguish flames while avoiding any unwanted consequences.

The lid traps smoke and soot within the jar
Candle lids are an essential accessory for candle enthusiasts. They are particularly useful for extinguishing flames, preventing dust and bugs, and preserving the scent of the candle. While some people prefer to blow out their candles or use a wick dipper, others opt for using the lid to snuff out the flame. This method involves gently setting the lid on top of the candle to smother the flame quickly.
It is important to note that simply resting the lid on top of the candle is sufficient to extinguish the flame. Pressing the lid down is unnecessary and may even cause issues. Doing so can create a vacuum seal, making it challenging to reopen the jar. Additionally, it can cause the jar to turn black due to the trapped smoke and soot. Therefore, it is recommended to avoid forcing the lid shut and instead allow the flame to go out gently.
The candle lid plays a crucial role in trapping smoke and soot within the jar. By gently placing the lid on top, the smoke and soot released during combustion are contained, preventing them from escaping into the surrounding area. This containment helps maintain the air quality and reduces the amount of residue that would otherwise accumulate in the room.
While the lid effectively traps smoke and soot, it is important to exercise caution. Some individuals have expressed concerns about the potential buildup of soot within the jar. To mitigate this issue, it is advisable to remove the lid after the flame has been extinguished to allow any remaining smoke to escape. This practice helps minimize the amount of soot that accumulates within the jar over time.
Overall, the candle lid is a valuable tool for managing the by-products of candle combustion. By using the lid to extinguish the flame and containing the smoke and soot, individuals can enjoy their candles while maintaining a relatively smoke-free and soot-free environment. However, it is essential to balance this containment by providing an outlet for the smoke to escape, thus reducing the buildup of soot within the jar.

Blowing out candles is not the best method
There are safer and more effective methods to extinguish a candle flame. Using a wick dipper or snuffer ensures a peaceful and worry-free candle experience. A wick dipper is a long piece of metal with a flat handle on one end and a thin tip with a bent hook on the other. You use it to gently press the lit candle wick into the wax pool, instantly snuffing out the flame, and then pull the wick back up. This method produces minimal smoke and re-coats your wick with a fresh layer of wax. Antique wick dippers are also prized by collectors and candle connoisseurs.
Another option is to use a candle snuffer, also known as a douter. These date back to the mid-17th century and are still popular today due to their effectiveness and safety. They work well with most candles, quickly extinguishing the flame and minimizing smoke. Modern candle snuffers are inexpensive and fashionably designed, and they come in various delightful forms, such as a beehive, disk, or pyramid.
If you are looking for a smokeless and aesthetically pleasing way to extinguish your candles, consider using a wick dipper or candle snuffer instead of blowing them out. These methods will lengthen the life of your candles and keep them sootless.

Safer methods include wick dippers or snuffers
Safer methods of extinguishing a candle include using wick dippers or snuffers. While blowing out a candle may seem like a straightforward solution, it can result in wax droplets being sprayed onto nearby surfaces or furniture. The wax spray is often so fine that it may go unnoticed initially, potentially causing unintended damage.
Wick dippers are slender, elegantly designed metal tools used in candle care and maintenance. They work by gently submerging the lit wick into the molten wax, cutting off the oxygen supply and extinguishing the flame without producing smoke or soot. This process also coats the wick with wax, priming it for the next burn and ensuring an even burn throughout each use. Wick dippers help maintain the integrity of the wick, enhancing the overall burn of the candle. They are also durable, with a sleek appearance, and their heat-resistant nature makes them a safe choice.
Candle snuffers, on the other hand, are tools that pinch or cover the wick, depriving the flame of oxygen and extinguishing it. The most common type is the bell-style snuffer, often crafted from silver or brass. While effective, they can lead to unnecessary smoking, making it challenging to relight the candle. Pinch-style snuffers, resembling small tongs, are better suited for smaller candles and produce very little smoke.
Both wick dippers and snuffers are safer alternatives to blowing out candles, minimising smoke and maintaining the condition of the wick for future use.
