Blowing out a candle may seem like a straightforward task, but there are several factors to consider, such as safety, effectiveness, and even science. While blowing out a candle is a widespread technique, it can be hazardous, causing hot wax and sparks to fly and creating smoke that can irritate the eyes and lungs. Additionally, the carbon dioxide in our breath does not solely contribute to extinguishing the flame. Instead, the key components are the forceful movement of air and the displacement of oxygen. So, when is the right time to blow out a candle?

What You'll Learn
Blowing out a candle is hazardous
Blowing out a candle is a common practice, but it can pose certain hazards. Firstly, there is a risk of spreading germs and bacteria. When a person blows out a candle, they may inadvertently spread respiratory droplets containing viruses or bacteria from their mouth and nose. This can be particularly concerning during a pandemic, such as COVID-19, where the risk of transmitting the virus through respiratory droplets is heightened.
Secondly, blowing out a candle can create a fire hazard. The act of blowing can cause the flame to spread and potentially ignite nearby objects, including flammable decorations, furniture, bedding, or clothing. Additionally, blowing out a candle can result in wax splatter, which can increase the risk of burns and further enhance the danger of a fire starting. The hot wax splatter could also cause burns if it comes into contact with the skin, especially if the candle is close to the person's face when they blow it out.
Furthermore, the traditional method of blowing out a candle can be hazardous to both individuals and the environment. The force of blowing can cause sparks and hot wax to fly in different directions, creating a risk of burns or starting a fire. Additionally, the use of breath to extinguish a candle produces more smoke compared to alternative methods, which can be irritating to the eyes and lungs.
To mitigate these risks, it is recommended to use safer alternatives for extinguishing candles, such as a candle snuffer or a candle dipper. A candle snuffer is specifically designed to safely and effectively put out candles, reducing the risk of hot wax and sparks flying around. On the other hand, a candle dipper involves dipping the wick into the wax, extinguishing the flame, and coating the wick with wax, making it easier to light the candle next time. These methods can help ensure a safer and more peaceful candle experience without the potential hazards associated with blowing out a candle.

Alternative methods to extinguish a candle
Blowing out a candle is the most obvious way to extinguish it, but there are other methods that can be used. Here are some alternative ways to put out a candle:
Using a Candle Snuffer
A candle snuffer is a long-stemmed metal rod with a small cone or bell-shaped structure at the end. To extinguish the candle, hold the snuffer over the candle and lower the bell end onto the lit flame. Ensure that the snuffer does not touch the melted wax. Once the flame is fully extinguished, remove the snuffer. This method is elegant and prevents debris from falling into the wax pool.
Using a Wick Dipper
A wick dipper is a long-handled tool with a hook at one end. To extinguish the candle, use the wick dipper to quickly dip the wick into the melted wax and then lift it back out. This method instantly puts out the candle with minimal smoke. It is one of the best ways to preserve the quality of the candle's wax and fragrance.
Using Your Fingers
Another way to extinguish a candle is to use your fingers. Lick the tips of your fingers and pinch the wick quickly. However, the main issue with this method is the risk of burning yourself, so be sure to release the wick quickly. Alternatively, you can use tweezers to grasp the wick and then bend it into the liquid wax. Remember to pull the wick out immediately and straighten it again.
Using the Lid
Some candles come with a lid, and while it is not recommended, you can use the lid to extinguish the flame. Simply place the lid back on the candle to deprive the flame of oxygen and put it out. However, this method can trap smoke and soot inside the jar, altering the fragrance of the candle and leaving a black residue. It is also important to ensure that the lid is not made of a flammable or heat-sensitive material.

Candle safety in the home
Candle safety is an important aspect of preventing fires in the home. Here are some tips to ensure safe candle usage:
Candle Placement
Keep burning candles away from open windows, fans, air conditioners, vents, or drafts. Moving air can disturb the flame, causing uneven burning, sooting, and excessive dripping. It is also important to keep candles away from heavily trafficked areas to prevent them from being knocked over. Place candles on a sturdy, heat-resistant surface that is large enough to catch any drips or melted wax. Ensure that the candle is not on or near anything that might catch fire, such as furniture, drapes, bedding, carpets, books, paper, or flammable decorations.
Trimming the Wick
Before lighting a candle, always trim the wick to between 1/8 and 1/4 inches long. This will ensure a cleaner, brighter burn and prevent the flame from becoming obscured. Long or crooked wicks can cause uneven burning, dripping, or flaring.
Lighting and Extinguishing
When lighting a candle, use long matches or a long-reach lighter. Keep hair and loose clothing away from the flame. Never leave a candle unattended, and make sure to keep them out of the reach of children and pets. To extinguish a candle, use a candle snuffer to prevent hot wax from splattering. Never use water to put out a candle, as it can cause the hot wax to splatter and may break a glass container.
Burning Time
In general, it is recommended that candles do not burn for longer than four hours and that they are allowed to cool for at least two hours before relighting. Discontinue burning a candle when there is about half an inch of wax left in the container or two inches if using a pillar candle.
Alternative Options
Consider using battery-operated flameless candles, which can look, smell, and feel like real candles but pose less of a fire risk.
By following these safety guidelines, you can enjoy your candles while minimizing the risk of fire hazards in your home.

How to burn a candle correctly
Burning a candle is easy, but there are several steps you should follow to ensure you are burning candles correctly and safely.
Firstly, before you light a candle, always trim the wick to between 1/8 and 1/4 of an inch long. You can use scissors, nail clippers, or a wick trimmer. Trimming the wick will give you a cleaner, brighter burn. Untrimmed wicks can take on a strange shape that dulls and obscures the flame. Long wicks can also cause smoky stains on your jar or tin candle container.
Secondly, when you first light a candle, let it burn for long enough to melt the wax from edge to edge of the container. This will take several hours, so don't light a candle unless you have the time to do so. If you don't let the wax melt all the way across, it will start to tunnel, wasting the wax on the edges.
Thirdly, candles should burn for one hour per inch in diameter of the candle size. For example, a candle that is 2 inches across should burn for 2 hours. Burning a candle for too long will cause carbon to collect on the wick, leading it to "mushroom". The wick will then become unstable and produce a dangerously large flame. It is recommended that candles are not burned for longer than four hours and that they cool for at least two hours before being relit.
Finally, do your best to keep your burning candle away from open windows, fans, air conditioners, or heavily trafficked areas. Moving air can disturb the flame, potentially causing stains and giving you tunneling and other issues.
To extinguish a candle, it is best not to blow it out. Blowing a candle out can cause it to smoke, and you could accidentally blow some of the melted wax off the candle. Instead, use a wick dipper, tweezers, or a knife to extinguish the candle.

Why candles blow out when you blow on them
When you blow on a candle, you are diluting the wax vapour and cooling it below the point where the wax and air molecules can react. The heat of the candle flame vaporizes the wax. Then, the hot wax vapour reacts with oxygen to produce the flame. When you blow on a candle, you are forcefully moving air and displacing oxygen, which is essential for combustion. The air you blow moves faster than the speed of the flame front, and the flame is moved away from its fuel source, where it burns out due to the lack of fuel.
The visible flame is extinguished, but the wick and surrounding air remain hot. In the absence of oxygen, the combustion process is incomplete, leaving behind vaporized wax or gaseous byproducts. The heat causes the candle wax to vaporize, turning into volatile gases. These gases rise from the wick and surround the candle.
The carbon in the wick can also turn into ash, making the candle harder to light the next time. This is why blowing out a candle can cause it to smoke.
It is important to note that blowing softly on a candle might actually make the flame more intense, as more oxygen is supplied to the flame.
