Do I need to open the window to ventilate the scented candles? Why is there a pit in the middle of the scented candles?

Many of us like to light scented candles in our daily lives, and scented candles have many benefits for us. Many people open windows for ventilation when lighting them, so do we need to open windows for ventilation when lighting scented candles? Why is there a pit in the middle when lighting a scented candle?

Do I need to open the window for ventilation when burning scented candles?

Some good scented candles are made of natural ingredients such as soy wax, which are non-toxic and harmless, and smokeless when burning. If the room is large enough, it is okay not to open the window for ventilation, as long as it is not a closed room, just make sure that the indoor air circulates. If the scented candle is made of paraffin, even food-grade paraffin, it contains certain harmful ingredients. Although the content is not high, it is harmful to the human body after all, so it is better to open the window for ventilation. If the room is small, it is recommended to open the window slightly, as long as it does not affect the fragrance too much, because the burning of scented candles consumes oxygen, which will reduce the indoor oxygen content. Insufficient oxygen may also generate carbon monoxide, so it is necessary to open the window for ventilation.

Why is there a hole in the middle when I light a scented candle?

When the candle burns, the heat radiates from the wick to the outside. It usually takes a certain amount of time for the outer edge of the scented candle to reach the ignition point. If the wick is suddenly extinguished at this time, the heat will not be enough to reach the outside, and only the middle part of the candle will melt. Over time, a pit like a "tunnel" will be formed in the middle of the candle. The "tunnel phenomenon" will affect the normal service life of the candle. To avoid the "tunnel phenomenon", it is best to ensure that it burns continuously for at least 2-4 hours when it is first lit, so that the heat can fully reach the outer edge of the candle. If the candle itself is large, when the scented candle burns, only the area around the wick is heated, and the heat cannot be transmitted to the edge. It is recommended to choose an iron candle holder. The thermal conductivity of iron metal is relatively strong, which can disperse the heat well, and the edge of the candle can also be heated and melted evenly. You can also wrap the upper part of the candle with tin foil and close it at the mouth of the cup. The range should be smaller than the candle cup itself. After burning for two hours, extinguish the candle and use chopsticks or cotton swabs to push the melted candle at the edge to the center. This method is more suitable for scented candles that have formed a memory circle.

How long does it take for a scented candle to have a scent?

Aromatherapy candles generally burn continuously for three to four hours. Aromatherapy candles are guaranteed to burn for three to four hours each time, which is enough for the aromatherapy candles to form a beautiful wax pool and make the fragrance strong enough. If the aromatherapy candles burn for too long, the fragrance will become stronger and stronger, and it is not good for the nose to smell too much. There are not many reasons for aromatherapy candles to produce black smoke, generally because of incomplete combustion or impure paraffin wax. Incompletely burned black smoke with particles drifting around can cause harm to the human body, and black smoke will also blacken white walls and ceilings. Note that every time before lighting an aromatherapy candle, use scissors to trim the candle wick to about 6-8mm. Aromatherapy candles should be kept away from direct sunlight when stored and used. If the aromatherapy candles are exposed to sunlight for a long time, they will fade and lose fragrance, which is not worth the loss. When your aromatherapy candles start to be used, it is best to light them up within six months after opening to avoid the volatilization of the essential oil components contained in them and the aromatherapy will no longer be fragrant.

Do scented candles have a shelf life?

There is no shelf life. Because it is a candle, it should be stored away from sunlight and heat sources, and placed in a dark and ventilated place. If possible, it can also be refrigerated. And please note that if you store scented candles in summer, you need to wrap them in plastic bags and be careful not to lose the oil. However, scented candles will add essential oils, and the essential oils and smells will evaporate over time. The shelf life of scented candles is much shorter than that of ordinary candles, and it is also related to the storage method of scented candles.
